KX6 outdoor series are available with special coating

applied for not only sheet metals but also small parts in

order to prevent salt corrosion caused by sea breeze in

area along coast line (Within approximately 500m fromcoast line).

Sea breeze

Sea

CautionEven if the outdoor unit is protected with the anti-salt damage treatment, it cannot be perfectly free from rusting.

The following points should be kept in mind during installation and maintenance of the outdoor units.

Installation(1) When installing the outdoor unit close to the coastal area, provide a windbreak to protect it from direct sea breeze and

salt water splash.

(2) Select a well-drained place to install.

(3) If any scratch or damages occurred on the outdoor unit during installation, repair it carefully.

Maintenance(1) Clean salt grains on the outdoor unit with fresh water periodically.

(2) Apply rust preventive at regular intervals for maintenance depending on the conditions at the installation place(consulting with the withstanding capacity).

(3) Confirm reset of screw tap after maintenance, if missing it may cause corrosion occurred from the hole of screw tap.

(4) During prolonged non operation periods, protect the unit with covering.

“CAUTION” Cooling operation under low outdoor air temperature conditions

KXE6 models can be operated in cooling mode at low outdoor air temperature condition within above temperature range. However 

in case of severely low temperature conditions if the following precaution is not observed, it may not be operated in spite of operable

temperature range mentioned above and cooling capacity may not be established under certain conditions.

[Precaution]

In case of severely low temperature condition

1) Install the outdoor unit at the place where strong wind cannot blow directly into the outdoor unit.

2) If there is no installation place where can prevent strong wind from directly blowing into the outdoor unit, prepare a windbreak 

fence or something like that locally in order to divert the strong wind from the outdoor unit.

[Reason]

Under the low outdoor air temperature conditions of -5 or lower, if strong wind directly blow into the outdoor unit, the outdoor heat

exchanger temperature will drop, even though the outdoor fan is stopped by outdoor fan control. This makes high and low pressuresto drop as well. This low pressure drop makes the indoor heat exchanger temperature to drop and will activate anti-frost control at

indoor heat exchanger at frequent intervals, that cooling operation may not be established for any given time.

 Note (1) A branch piping system cannot be connected after a header system.(2) 90m or less (However, difference between the longest and shortest piping : 40m or less)

(3) The indoor unit of 224 or 280 capacity cannot be connected to the header.

(2) Capacity calculation method

(a) Calculating the indoor unit capacity compensation

Indoor unit capacity (cooling, heating) = Indoor unit total rated capacity

× Capacity compensation coef ficient according to temperature conditions

See item (3) (a) concerning the capacity compensation coef ficient according to temperature conditions.

(b) Calculating the outdoor unit capacity compensationOutdoor Unit Capacity (Cooling, Heating) = Outdoor unit rated capacity (rated capacity when 100% connected)

  × Capacity compensation coef ficient according to temperature conditions

  × Capacity compensation coef ficient according to piping length

  × Capacity compensation coef ficient according to height difference

× Correction of heating capacity in relation to the frost on the outdoor unit

  × Capacity compensation coefficient according to indoor unit connection

capacity

See item (3) (a) concerning the capacity compensation coef ficient according to temperature conditions.

See item (3) (c) concerning the capacity compensation coef ficient according to piping length.

See item (3) (d) concerning the capacity compensation coef ficient according to height difference. This compensation

should be carried out only in cases where the outdoor unit is lower during cooling and higher during heating.See item (3) (e) correction of heating capacity in relation to the frost on the outdoor unit heat exchanger. This compen-

sation should be carried out only when calculating the heating capacity.

See item (3) (f) concerning the capacity compensation coef ficient according to indoor unit connected capacity. This

compensation should be carried out only in cases where the indoor unit total capacity is 100% or higher.

(c) Calculating system capacity

Compare the capacities determined in items (a) and (b) above and let the smaller value be the system capacity (cooling,

heating).

In cases where indoor unit total capacity (cooling, heating) > outdoor unit capacity (cooling, heating)

System capacity (cooling, heating) = Outdoor unit capacity (cooling, heating)

In cases where indoor unit total capacity (cooling, heating) < outdoor unit capacity (cooling, heating)

System capacity (cooling, heating) = Indoor unit capacity (cooling, heating)

(d) Calculating indoor unit capacity [item (c) 1 only]Indoor unit capacity (cooling, heating) = System capacity (cooling, heating)

(e) Correction of heating capacity in relation to the frost on the outdoor unit heat exchanger

(d) When the outdoor unit is located at a lower height than the indoor unit in cooling operation and when the outdoor unit is located at a higher height than the indoor unit in heating operation, the following values

should be subtracted from the values in the above table.

The correction factors will change drastically according to weather conditions. So necessary adjustment should be

made empirically according to the weather data of the particular area.

 Note (1) Equivalen t piping length can be obtained by calculating as follows.

Equivalent piping length = Real gas piping length + Number of bends in gas piping sEquivalent piping length of bends.

② Selection of installation location for the indoor unit

1Select the suitable areas to install the unit under approval of the user.x Areas where the indoor unit can deliver hot and cold wind sufficiently. Suggest to the user to use

a circulator if the ceiling height is over 3m to avoid warm air being accumulated on the ceiling.x Areas where there is enough space to install and service.x Areas where it can be drained properly. Areas where drain pipe descending slope can be taken.x Areas where there is no obstruction of airflow on both air return grille and air supply port.x Areas where fire alarm will not be accidentally activated by the air conditioner.x Areas where the supply air does not short-circuit.

x Areas where it is not influenced by draft air.x Areas not exposed to direct sunlight.x Areas where dew point is lower than around 28°C and relative humidity is lower than 80%.

This indoor unit is tested under the condition of JIS (Japan Industrial Standard) high humiditycondition and confirmed there is no problem. However, there is some risk of condensation dropif the air conditioner is operated under the severer condition than mentioned above.If there is a possibility to use it under such a condition, attach additional insulation of 10 to20mm thick for entire surface of indoor unit, refrigeration pipe and drain pipe.

x Areas where TV and radio stays away more than 1m. (It could cause jamming and noise.)x Areas where any items which will be damaged by getting wet are not placed such as food, table

wares, server, or medical equipment under the unit.x Areas where there is no influence by the heat which cookware generates.x Areas where not exposed to oil mist, powder and/or steam directly such as above fryer.x Areas where lighting device such as fluorescent light or incandescent light doesn’t affect the

operation.(A beam from lighting device so metimes affects the infrared receiver for the wireless remotecontroller and the air conditioner might not work properly.)

2Check if the place where the air conditioner is installed can hold the weight of the unit. If it is notable to hold, reinforce the structure with boards and beams strong enough to hold it. If the strengthis not enough, it could cause injury due to unit falling.

3 If there are 2 units of wireless type, keep them away for more than 5m to avoid malfunction due tocross communication.

4When plural indoor units are installed nearby, keep them away for more than 4m.

Space for installation and service

z When it is not possible to keep enough space between indoor unit and wall or between indoor units,close the air supply port where it is not possible to keep space and confirm there is no short circuitof airflow.

z Install the indoor unit at a height of more than 2.5m above the floor.

④ Installation of indoor unit (continued)

6. Make sure to install the indoor unit horizontally. Confirm thelevelness of the indoor unit with a level gauge or transparenthose filled with water. Keep the height difference at both ends ofthe indoor unit within 3mm.

7. Tighten four upper nuts and fix the unit after height and levelnessadjustment.

Caution

z Do not adjust the height by adjusting upper nuts. It will cause unexpected stress on the indoor unitand it will lead to deformation of the unit, failure of attaching a panel, and generating noise from thefan.

z Make sure to install the indoor unit horizontally and set the gap between the unit underside andthe ceiling plane properly. Improper installation may cause air leakage, dew condensation, waterleakage and noise.

z Even after decorative panel attached, still the unit height can be adjusted finely. Refer to theinstallation manual for decorative panel for details.

z Make sure there is no gap between decoration panel and ceiling surface, and between decorationpanel and the indoor unit. The gap may cause air leakage, dew condensation and water leakage.

z In case decorative panel is not installed at the same time, or ceiling material is installed after theunit installed, put the cardboard template for installation attached on the package (packing materialof cardboard box) on the bottom of the unit in order to avoid dust coming into the indoor unit.

⑤ Refrigerant pipe

Caution

z Use the new refrigerant pipe.When re-using the existing pipe system for R22 or R407C, pay attention to the following items.x Change the flare nuts with the attached ones (JIS category 2), and reprocess the flare parts.x Do not use thin-walled pipes.

z Use phosphorus deoxidized copper alloy seamless pipe (C1220T specified in JIS H3300) forrefrigeration pipe installation.  In addition, make sure there is no damage both inside and outside of the pipe, and no harmfulsubstances such as sulfur, oxide, dust or a contaminant stuck on the pipes.

z Do not use any refrigerant other than R410A.Using other refrigerant except R410A (R22 etc.) may degrade inside refrigeration oil. And air gettinginto refrigeration circuit may cause over-pressure and resultant it may result in bursting, etc.

z Store the copper pipes indoors and seal the both end of them until they are brazed in order to avoidany dust, dirt or water getting into pipe. Otherwise it will cause deg radation of refrigeration oil andcompressor breakdown, etc.

z Use special tools for R410 refrigerant.

Work procedure

1. Remove the flare nut and blind flanges on the pipe of the indoor unit.Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and givingtorque to the nut with another spanner in order to avoid unexpected stress to the copper pipe,and then remove them.(Gas may come out at this time, but it is not abnormal.)

z Pay attention whether the flare nut pops out. (as the indoor unit is sometimes pressured.)2. Make a flare on liquid pipe and gas pipe, and connect the refrigeration pipes on the indoor unit.

Bend the pipe with as big radius as possible and do not bend the pipe repeatedly. In addition, do

not twist and crush the pipes.Do a flare connection as follows:

z Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and givingtorque to the nut with another spanner in order to avoid unexpected stress to the copper pipe,and then remove them.

z When fastening the flare nut, align the refrigeration pipe with the center of flare nut, screw thenut for 3-4 times by hand and then tighten it by spanner with the specified torque mentionedin the table below. Make sure to hold the pipe on the indoor unit securely by a spanner whentightening the nut in order to avoid unexpected stress on the copper pipe.

3. Cover the flare connection part of the indoor unit with attached insulation material after a gasleakage inspection, and tighten both ends with attached straps.z Make sure to insulate both gas pipes and liquid pipes completely.

Incomplete insulation may cause dew condensation or water dropping.4. Refrigerant is charged in the outdoor unit.

As for the additional refrigerant charge for the indoor unit and piping, refer to the installation manualattached to the outdoor unit.

2. Prepare a joint for connecting VP-20 pipe, adhere and connect the joint to the drain hose (the endmade of rigid PVC), and adhere and connect VP-20 pipe (prepare on site).

As for drain pipe, apply VP-20 made of rigid PVC which is on the market.z Make sure that the adhesive will not get into the supplied drain hose.

It may cause the flexible part broken after the adhesive is dried up and gets rigid.z Do not bend or make an excess offset on the drain hose as shown in the picture.

Bend or excess offset will cause drain leakage.

Over20mm

3. Make sure to make descending slope of greater than 1/100 and do not make up-down bend and/ortrap in the midway.z Pay attention not to give stress on the pipe on the indoor unit side, and support and fix the pipe

as close place to the unit as possible when connecting the drain pipe.z Do not set up air vent.

z When sharing a drain pipe for more than oneunit, lay the main pipe 100mm below the drainoutlet of the unit. In addition, select VP-30 orbigger size for main drain pipe.

4. Insulate the drain pipe.z Be sure to insulate the drain socket and rigid PVC pipe installed indoors otherwise it may cause

dew condensation and water leakage.After drainage test implementation, cover the drain socket part with pipe cover (small size),then use the pipe cover (big size) to cover the pipe cover (small size), clamps and part of thedrain hose, and fix and wrap it with tapes to wrap and make joint part gapless.

Drain up

z The position for drain pipe outlet can be raised up to 600mm above the ceiling. Use elbows forinstallation to avoid obstacles inside ceiling. If the horizontal drain pipe is too long before verticalpipe, the backflow of water will increase when the unit is stopped, and it may cause overflow ofwater from the drain pan on the indoor unit. In order to avoid overflow, keep the horizontal pipelength and offset of the pipe within the limit shown in the figure below.

Caution

z Install the drain pipe according to the installation manual in order to drain properly.  Imperfection in draining may cause flood indoors and wetting the household goods etc.z Do not put the drain pipe directly into the ditch where toxic gas such as sulfur, the other harmful and  inflammable gas is generated. Toxic gas would flow into the room and it would cause serious

damage to user’s health and safety (some poisoning or deficiency of oxygen). In addition, it maycause corrosion of heat exchanger and bad smell.

z Connect the pipe securely to avoid water leakage from the joint.z Insulate the pipe properly to avoid condensation drop.z Check if the water can flow out properly from both the drain outlet on the indoor unit and the end of

the drain pipe after installation.z Make sure to make descending slope of greater than 1/100 and do not make up-down bend and/or

trap in the midway. In addition, do not put air vent on the drain pipe. Check if water is drainedout properly from the pipe during commissioning. Also, keep sufficient space for inspection andmaintenance.

② Open the suction grille, hang the panel onto 2 bolts, and secure it temporarily.

When securing the panel temporarily, hang the panel onto side bolts as shown in

the left figure, then hang onto side while turning it.

③ Tighten the temporarily secured hanging bolts and other 2 hanging bolts.

④ Remove 2 screws on the control box, and open the cover.

⑤ Connect the connector for louver motor (white 4P) and the connector for limit switch

(white 3P).

The connector on the indoor unit side is in the control box.

⑥ After connecting the connectors, pass the wiring on the panel side through wiring

hole. Hold the connector in the control box.

⑦ Close control box cover, and tighten 2 screws.

⑧ Mount the chain attached with suction grille on the panel using screw. The screws for

mounting chain and hanging bolts are in the same bag.

⑨ Close suction grille, then work is completed.

⑩ If the louver cannot be moved by remote control operation, cut off the power for over 10

seconds after confirming the connection of connector, then turn on the power again.

7.2 Electrlc wiring work instruction 

●Install an over-current and earth leakage brea ker (threshold current: 30mA) specified foreach unit without fail.

●Provide a dedicated branchin g circuit and never share a branching circuit with otherequipment. If shared, disconnection at the circuit breaker may occur, which can causesecondary damage.

●Set earth of D-type.

●Connection of a cable beyond 3.5 mm 2 is not permitted. When cables of over 5.5 mm2 arein use, provide a dedicated pull box to take a branch to an indoor unit.

●Keep "remote controller line" and "power source line" away from each other on constructingof unit outside.

●Run the lines (power source, remote controller and "between indoor and outdoor unit")upper ceiling through iron pipe or other tube protection to avoid the damage by mouse andso on.

●Do not add cord in the middle of line (of indoor power source, remote controller and signal)route on outside of unit. If connecting point is flooded, it could cause problem as for electricor communication.(In the case that it is necessary to set connecting point on the signal line way, performthorough waterproof measurement.)

●Do not connect the power source line [220V/240V/380V/415V] to signal side terminal block.Otherwise, it could cause failure.

●Screw the line to terminal block without any looseness, certainly.

●Do not turn on the switch of power source, before all of line work is done.

ƽElectrical wiring work must be performed by an electlician an qualified by alocal power provider. These wiring specifications are determ ined on theassumption that the following instructions are observed:① Do not use cords other than copper ones.

Do not use any supply line lighter than one specified in parentheses for each type below.

-braided cord (code designation 60245 IEC 51), if allowed in the relevant part 2;

-

ordinary tough rubber sheathed cord (code designation 60245 IEC 53);-flat twin tinsel cord (code designation 60227 IEC 41);-ordinary polyvinyl chloride sheathed cord (code designation 60227 IEC 53);

②Provide a separate power outlet for each outdoor or indoor unit.

③ All indoor units grouped in one system must have power source that can be turned on or off simultaneously.

④ Pay extra attention so as not to confuse signal line and power source line connection, because an error in theirconnection can be burn all the boards at once.

ƽConnection of the line ("Between indoor and outdoor unit", Earth and Remote controller)① Remove lid of control box before connect the above lines, and connect the lines to terminal block according to

number pointed on label of terminal block.In addition, pay enough attention to confirm the number to lines, because there is electrical polarity except earth line.Furthermore, connect earth line to earth position of terminal block of power source.

② Install earth leakage breaker on power source line. In addition, select the type of breaker for inverter circuit asearth leakage breaker.

③ If the function of selected earth leakage breaker is only for earth-fault protection, hand switch (switch itself and type"B" fuse) or circuit breaker is required in series with the earth leakage breaker.

Note (1) The cord distances are calculated with a voltage drop of 2%. If the distance should exceed theabove data, review the cord thickness to use in accordance with your extension cord regulations.

(2) When total extension of remote controller line is more than 100m, change the size of cordaccording to "③ Remote Control, Wiring and functions".

In case of Heat recovery 3-pipe systems

Branching controller of heat recovery 3-pipe systems wiring

●When this unit is used as a "Heat Recovery 3-pipe Systems", refer to the installationmanual of a branching controller (option).

Address setting is done by (1) Manual address setting or (2) Automatic address setting.In the case of (2) "Automatic address setting", it is possible to change address setting by wiredremote controller after once complete setting.As for details of setting procedure, refer to instructions attached to the outdoor unit for details.

Installation and wiring of remote controller

Remote controller

ƽBe sure to have the electrical wiring work done by qualified electric alinstaller, and use exclusive circuit.Power source with insufficient capacity and improper work can cause electric shock and fire.

ƽUse specified wire for electrical wiring, fasten the wiring to the terminalsecurely, and hold the cable securely in order not to apply unexpectedstress on the terminal.Loose connections or hold could result in abnormal heat generation or fire.

ƽArrange the electrical wires in the control box properly to prevent them fromrising. Fit the lid of the services panel property.Improper fitting may cause abnormal heat and fire.

ƽMake sure there is no dust or clogging on both the plug and the socket norloose connection of the socket before plugging, and plug in securely to theend of the blade.Accumulation of dust, clogging on the socket or plug, or loose installation of the socket could causeelectric shock and fire. Replace the socket if it is loose.

ƽUse the genuine optional parts. And installation should be performed by aspecialist.

● Do not use any refrigerant other than R410A. R410A will rise to pressure about 1.6 times higher than that of a conventional refrigerant.● A unit designed for R410A has adopted a different size outdoor unit service valve charge port and a different size check joint provided in the unit to

prevent the charging of a wrong refrigerant by mistake. The processed dimension of the flared part of a refrigerant pipe and a flare nut's parallel sidemeasurement have also been altered to raise strength against pressure. Accordingly, you are required to arrange dedicated R410A tools listed in thetable on the right before installing or servicing this unit.

● Do not use a charge cylinder. The use of a charge cylinder will cause the refrigerant composition to change, which results in performance degradation.● In charging refrigerant, always take it out from a cylinder in the liquid phase.● All indoor units must be models designed exclusively for R410A. Please check connectable indoor unit models in a catalog, etc.

(A wrong indoor unit, if connected into the system, will impair proper system operation)

Caution●Be sure to read this manual before installation to follow the proper installation methods.

●When installing the indoor unit, read the installation manual of indoor unit.

Refrigerant pipe distribution parts, which are not contained in the package, will be required for installation. As for refrigerant pipe distribution parts, we offer branching pipe sets (Model type: DIS) and header sets (Model type: HEAD) as parts used on the indoor side of piping.Please select one suiting your application. In selecting distribution parts, please also refer to “4. REFRIGERANT PIPING.”If you are not sure which parts to select, please consult with your dealer or the manufacture.Use refrigerant branching pipe sets and header sets designed exclusively for R410A without fail.

2. INSTALLATION LOCATION  (Obtain approval from the customer when selecting the installation area.)

2-1. Selecting the installation location〇 Where air is not trapped.〇 Where the installation fittings can be firmly installed.〇 Where any object does not prevent inlet or outlet air.〇 Out of the heat range of other heat sources.〇Where strong winds will not blow against the outlet air.

〇 A place where stringent regulation of electric noises is applicable.〇 Where it is safe for the drain water to be discharged.〇 Where noise and hot air will not bother neighboring residents.〇 Where snow will not accumulate.〇 A place where no TV set or radio receiver is placed within 5m.

(If electrical interference is caused, seek a place less likely to cause the problem)Please note

a) If there is a possibility of a short-circuit, then install a flex flow adapter.b) When installing multiple units, provide sufficient intake space so that a short-circuit does not occur.c) In areas where there is snowfall, install the unit in a frame or under a snow hood to prevent snow from accumulating on it.

(Inhibition of collective drain discharge in a snowy country)d) Do not install the equipment in areas where there is a danger for potential explosive atmosphere.e) Install the equipment in a location that can sufficiently support the weight of the equipment.f)  If a unit is installed into a special environment as shown below, there will be a danger that the corrosion of the outdoor unit or its

malfunctioning is caused. If this is the case, please consult with the distributor from whom you have purchased the unit.・Where corrosive gas is generated (such as a hot-spring resort area).・Where the unit is subject to sea breezes (coastal area).・Where the unit is subject to oil mists.・Where equipment generating electromagnetic waves exists in the vicinity.

g) When strong winds occur  ● Where it is likely that the unit is subjected to strong winds, provide wind guards according to the following guidelines.  Strong winds can cause performance degradation, an accidental stop due to a rise of high pressure and a broken fan.

CAUTION

Please leave sufficient clearancearound the unit without fail.Otherwise, a risk of compressorand/or electric component failuremay arise.

(1) Check operationThe following ① – ③ can be checked automatically with this operation.

  ① Checking of operation valves opened/closed.

Checks to see if operation valves are opened.

  ② Checking of mismatch on wiring or piping.Checks to see if refrigerant piping or signal wiring between indoor and outdoor units in the same refrigerant system are

connected properly.

  ③ Checking of indoor expansion valve operation.

Checks to see if indoor expansion valve operates properly.

* Check operation should be performed before initial test run after completion of installation.

When any corrective measure for nonconformity has been taken, perform the check operation again after repair.

Operational condition

Temperature range: Outdoor air temperature … 0㨪 43℃, Indoor air temperature … 10 㨪 32℃.

Connecting capacity of indoor units: 80% or more of outdoor unit capacity.

Precautions

Check each outdoor unit system for single use or each refrigeration system for combination use.

Outdoor units in other refrigerant system shall not be operated.

 After turning on power supply to outdoor unit and connected indoor units, start check operation with all connected indoor

units stopped.

In combination use, check the setting and the result displayed on the 7-segment display of master outdoor unit.

If the unit has been operating before check operation, wait for 5 minutes after stopping the unit operation before starting

check operation, in order to avoid misjudgment.

In combination use, judging operation valves opened or closed by check operation can be done as no good (NG), when

all of operation valves in liquid l ine, gas line and oil equalizing line of both master and slave outdoor units are closed.

However, in other cases than the above, judgment may not be done.

During check operation it is impossible to stop operation from remote controller. Accordingly, before starting check operation,

be sure to confirm that no one working near the indoor unit especially near the rotating part such as fan of indoor unit or

something is remaining near the fan of indoor unit.

Purpose

The purpose of this check operation is only to verify any overlooked items to be checked during the ordinary checking doneޓ

at the site after installation. Accordingly it has no function to substitute the ordinary checking to be done during or after installation

work and to restore automatically as a result of checking operation.

.Therefore be sure to conduct the checking in ordinary way after installation firstly, and then to perform this check operationޓ

We believe that this checking method could prevent from overlooking any items to be checked.

(3) Confirmation before check operation

Confirm the installation has been completed properly by hearing, actual inspection or other method.

This preliminary confirmation is indispensable to prevent troubles during or after check operation.

Check operation can be performed only when the following conditions (1) – (8) are established.

Check the following contents listed in the table with 7-segment display and MentePC.

Item Content Check method Check result

(1) Preparation Supply power to outdoor and

indoor units.

No outdoor unit in other

refrigerant systems is operating.

 All indoor units are stopped.

It has elapsed more than 5

minutes after the stopping.

(2) Connecting capacity of

indoor units

Connecting capacity of indoor

units is 80% or more of outdoor

unit capacity.

Check capacities of outdoor and indoor units.

(3) Address setting  Addresses of outdoor unit

(in combination use, both of master

and slave outdoor units) and

indoor units have been set.

Check the number of connected units.

(4) Temperature range Outdoor air temperature is 0 –

43℃. Indoor air temperature is

10 – 32℃.

Check outdoor air temperature with 7-segment

display and indoor air temperature with

MentePC.

(5) Others System communicating method

is of new SL.

Check the model name of outdoor unit, indoor

units, central control device, etc.

System is not in error stopcondition.

Check to see if any error code (E??) isdisplayed on indoor or outdoor unit.

(6) Outdoor unit operation

valve

Outdoor unit operation valve is

opened. *1

Check visually.

(7) Refrigerant amount Proper amount of refrigerant is

charged.

Check the additional charged amount of

refrigerant is written in the plate for specifying

refrigerant charging amount on the back of

outdoor service panel.

(8) Number of connected

indoor units

It is same as the number of

connected indoor units installed.

Check with 7-segement display or MentePC.

*1 Be sure to open the operation valves in both liquid and gas lines of outdoor unit before starting check operation. In combination use,

open the operation valves not only in liquid and gas lines but also in oil equalizing line of both master and slave outdoor units.

 Operating with operation valves closed causes vacuum operation that results in a compressor fault.

 If the operation valves are “closed” before test run, be sure to verify whether the evacuation, air tightness test and additional refrigerant

charge have been completed by hearing to installation contractor, before opening the operation valves.

Otherwise, it may cause such trouble as mixing air (non-condensation gas and water) in, forgetting to charge additional refrigerant

at the site, or others.

ead together with indoor unit's installation manual.

WARNING

● Fasten the wiring to theterminal securely and hold the cable securely so as not to applyunexpected stress on the terminal.

  Loose connection or hold will cause abnormal heat generation or fire.

● Make sure the power supply is turned off when electric wiring work.

  Otherwise, electric shock, malfunction and improper running may occur.

CAUTION

● DO NOT leave the remote controller without the upper case.

  In case the upper cace needs to be detached, protect the remote controller with a packaging box

or bag in order to keep it away from water and dust.

● DO NOT install the remote controller at the following places in order to avoid malfunction.

  (1) Places exposed to direct sunlight  (4) Hot surface or cold surface enough to generate condensation

  (2) Places near heat devices  (5) Places exposed to oil mist or steam directly

  (3) High humidity places  (6) Uneven surface

 Accessories Remote controller, wood screw (Ǿ3.5×16) 2 pieces

Prepare on site Remote controller cord (2 cores) (Refer to [2. Installation and wiring of remote controller])

  [In case of embedding cord] Electrical box, M4 screw (2 pieces)

  [In case of exposing cord] Cord clamp (if needed)

1. Installation procedure

In case of embedding cord

⑴ Make certain to remove the screw on the bottom

surface of the remote controller.

⑵ Remove the upper case of the remote controller.

  Insert a flat-blade screwdriver to a concave portion of the bottom

surface of the remote controller and slightly twist it, and the case is

removed.

⑶ Pre-bury the electrical box and remote controller cord.

⑷ Prepare two M4 screws (recommended length: 12– 16mm), and install the lower case to the electrical box.

  Do not use a screw whose screw head is larger than the height of the wall around the screw hole.

⑸ Connect the remote controller cord to the terminal block.

  Connect the terminals (X and Y) of the remote controller and the terminals (X and Y) of the indoor

unit. (No polarity of X and Y)

⑹ Mount the upper case for restoring to its former state so as not to crimp the remote controller cord,

and secure with the removed screw.

In case of exposing cord

⑴ Make certain to remove a screw on the bottom surface of the

remote controller.

⑵ Remove the upper case of the remote controller.

Insert a flat-blade screwdriver to a concave portion of

the bottom surface of the remote control and slightly

twist it, and the case is removed.

⑶ The remote controller cord can be extracted from the

upper center.

 After the thin part in the upper side of the remote

controller upper case is scraped with a nipper or knife,

remove burr with a file.

⑷ The lower case of the remote controller is mounted to

a flat wall with two accessory wood screws.

⑸ Connect the remote controller cord to the terminal block.

Connect the terminals (X and Y) of the remote controller and

the terminals (X and Y) of the indoor unit. (No polarity of X and

 Y)

The wiring route is as shown in the right.

The wiring in the remote controller case should be 0.3 mm2

(recommended) to 0.5 mm2

at

maximum.

Further, peel off the sheath.

The peeling length of each wiring is as follows:

X wiring : 160mm

 Y wiring : 150mm

⑹ Mount the upper case for res to ring to i ts former s ta te so as not to

crimp the remote controller cord, and secure with the removed screw.

⑺ In the case of exposing installation, secure the remote controller cord to the wall surface with a

cord clamp so as not to loosen the remote controller cord.

2. Installation and wiring of remote controller

⑴ Wiring of remote controller should use 0.3mm2

× 2 core wires or cables. (on-site configuration)

⑵ Maximum prolongation of remote controller wiring is 600 m.

If the prolongation is over 100m, change to the size below.

But, the wiring in the remote controller case should be 0.3mm2

(recommended) to 0.5mm2.

Change the wire size outside of the case according to wire connecting. Waterproof treatment is

necessary at the wire

connecting section. Be careful about contact failure.
