2. REFRIGERANT R410A
This air conditioner adopts the new refrigerant HFC(R410A) which does not damage the ozone layer.
The working pressure of the new refrigerant R410Ais 1.6 times higher than conventional refrigerant(R22). The refrigerating oil is also changed in
accordance with change of refrigerant, so be carefulthat water, dust, and existing refrigerant or refrigerat-ing oil are not entered in the refrigerant cycle of theair conditioner using the new refrigerant duringinstallation work or servicing time.
The next section describes the precautions for airconditioner using the new refrigerant. Conforming tocontents of the next section together with thegeneral cautions included in this manual, performthe correct and safe work.
2-1. Safety During Installation/Servicing
As R410As pressure is about 1.6 times higher thanthat of R22, improper installation/servicing maycause a serious trouble. By using tools and materi-als exclusive for R410A, it is necessary to carry outinstallation/servicing safely while taking the followingprecautions into consideration.
(1) Never use refrigerant other than R410A in an airconditioner which is designed to operate withR410A.
If other refrigerant than R410A is mixed, pres-sure in the refrigeration cycle becomes abnor-
mally high, and it may cause personal injury, etc.by a rupture.
(2) Confirm the used refrigerant name, and usetools and materials exclusive for the refrigerantR410A.
The refrigerant name R410A is indicated on thevisible place of the outdoor unit of the air condi-tioner using R410A as refrigerant. To preventmischarging, the diameter of the service portdiffers from that of R22.
(3) If a refrigeration gas leakage occurs duringinstallation/servicing, be sure to ventilate fully.
If the refrigerant gas comes into contact with fire,a poisonous gas may occur.
(4) When installing or removing an air conditioner,do not allow air or moisture to remain in therefrigeration cycle. Otherwise, pressure in therefrigeration cycle may become abnormally highso that a rupture or personal injury may becaused.
(5) After completion of installation work, check tomake sure that there is no refrigeration gasleakage.
If the refrigerant gas leaks into the room, cominginto contact with fire in the fan-driven heater,
space heater, etc., a poisonous gas may occur.
(6) When an air conditioning system charged with alarge volume of refrigerant is installed in a smallroom, it is necessary to exercise care so that,even when refrigerant leaks, its concentrationdoes not exceed the marginal level.
If the refrigerant gas leakage occurs and itsconcentration exceeds the marginal level, anoxygen starvation accident may result.
(7) Be sure to carry out installation or removalaccording to the installation manual.
Improper installation may cause refrigerationtrouble, water leakage, electric shock, fire, etc.
(8) Unauthorized modifications to the air conditionermay be dangerous. If a breakdown occursplease call a qualified air conditioner technicianor electrician.
Improper repairs may result in water leakage,electric shock and fire, etc.
2-2. Refrigerant Piping Installation
2-2-1. Piping Materials and Joints Used
For the refrigerant piping installation, copper pipesand joints are mainly used. Copper pipes and jointssuitable for the refrigerant must be chosen andinstalled. Furthermore, it is necessary to use cleancopper pipes and joints whose interior surfaces areless affected by contaminants.
(1) Copper Pipes
It is necessary to use seamless copper pipeswhich are made of either copper or copper alloyand it is desirable that the amount of residual oilis less than 40 mg/10 m. Do not use copper
pipes having a collapsed, deformed or discol-ored portion (especially on the interior surface).
Otherwise, the expansion valve or capillary tubemay become blocked with contaminants.
As an air conditioner using R410A incurspressure higher than when using R22, it isnecessary to choose adequate materials.
Thicknesses of copper pipes used with R410Aare as shown in Table 2-2-1. Never use copperpipes thinner than 0.8 mm even when it isavailable on the market.

a) Flare Joints
Flare joints used to connect the copper pipes
cannot be used for pipings whose outerdiameter exceeds 20 mm. In such a case,socket joints can be used.
Sizes of flare pipe ends, flare joint ends andflare nuts are as shown in Tables 2-2-3 to 2-2-6 below.
b) Socket Joints
Socket joints are such that they are brazedfor connections, and used mainly for thickpipings whose diameter is larger than 20 mm.
Thicknesses of socket joints are as shown inTable 2-2-2.

2-2-2. Processing of Piping Materials
When performing the refrigerant piping installation,care should be taken to ensure that water or dustdoes not enter the pipe interior, that no other oilother than lubricating oils used in the installed airconditioner is used, and that refrigerant does notleak. When using lubricating oils in the pipingprocessing, use such lubricating oils whose watercontent has been removed. When stored, be sure toseal the container with an airtight cap or any othercover.
(1) Flare Processing Procedures and Precautions
a) Cutting the PipeBy means of a pipe cutter, slowly cut the pipeso that it is not deformed.
b) Removing Burrs and Chips
If the flared section has chips or burrs,refrigerant leakage may occur. Carefullyremove all burrs and clean the cut surfacebefore installation.

c) Insertion of Flare Nut
d) Flare Processing
Make certain that a clamp bar and copperpipe have been cleaned.
By means of the clamp bar, perform the flareprocessing correctly.
Use either a flare tool for R410A or conven-tional flare tool.
Flare processing dimensions differ accordingto the type of flare tool. When using a con-ventional flare tool, be sure to secure dimen-sion Aby using a gauge for size adjust-ment.

(2) Flare Connecting Procedures and Precautions
a) Make sure that the flare and union portionsdo not have any scar or dust, etc.
b) Correctly align the processed flare surfacewith the union axis.
c) Tighten the flare with designated torque bymeans of a torque wrench. The tighteningtorque for R410A is the same as that forconventional R22. Incidentally, when thetorque is weak, the gas leakage may occur.
When it is strong, the flare nut may crack andmay be made non-removable. When choos-ing the tightening torque, comply with valuesdesignated by manufacturers. Table 2-2-7shows reference values.
Note :
When applying oil to the flare surface, be sure to useoil designated by the manufacturer. If any other oil is
used, the lubricating oils may deteriorate and causethe compressor to burn out.

2-3. Tools
2-3-1. Required Tools
The service port diameter of packed valve of the outdoor unit in the air conditioner using R410A is changed toprevent mixing of other refrigerant. To reinforce the pressure-resisting strength, flare processing dimensions andopposite side dimension of flare nut (For 12.7 copper pipe) of the refrigerant piping are lengthened.
The used refrigerating oil is changed, and mixing of oil may cause a trouble such as generation of sludge,
clogging of capillary, etc. Accordingly, the tools to be used are classified into the following three types.(1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))
(2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)
(3) Tools commonly used for R410A and for conventional refrigerant (R22)
The table below shows the tools exclusive for R410A and their interchangeability.

2-4. Recharging of Refrigerant
When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to thefollowing steps.
Connect the charge hose to packed valve serviceport at the outdoor units gas side.
Recover the refrigerant, and check no refrigerantremains in the equipment.
(For refrigerant charging, see the figure below.)
Connect the charge hose of the vacuum pumpadapter.
Open fully both packed valves at liquid and gassides.
Place the handle of the gauge manifold Low in thefully opened position, and turn on the vacuumpumps power switch. Then, evacuating therefrigerant in the cycle.
When the compound gauges pointer has indicated0.1 Mpa (76 cmHg), place the handle Low in the
fully closed position, and turn off the vacuumpumps power switch.
Keep the status as it is for 1 to 2 minutes, and ensurethat the compound gauges pointer does not return.
Set the refrigerant cylinder to the electronic balance,connect the connecting hose to the cylinder and theconnecting port of the electronic balance, and chargeliquid refrigerant.
Never charge refrigerant exceeding the specified amount.
If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode.
Do not carry out additional charging.
When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in therefrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the speci-
fied amount is charged, and working pressure in the refrigeration cycle becomes abnormally high pres-sure, and may cause a rupture or personal injury.

Be sure to make setting so that liquid can be charged.
When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down.
It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant.
Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning thecylinder upside down if cylinder is not equipped with siphon.
R410A refrigerant is HFC mixed refrigerant.Therefore, if it is charged with gas, the compo-sition of the charged refrigerant changes andthe characteristics of the equipment varies.

2-5. Brazing of Pipes
2-5-1. Materials for Brazing
(1) Silver brazing filler
Silver brazing filler is an alloy mainly composedof silver and copper. It is used to join iron, copperor copper alloy, and is relatively expen-sivethough it excels in solderability.
(2) Phosphor bronze brazing filler
Phosphor bronze brazing filler is generally usedto join copper or copper alloy.
(3) Low temperature brazing filler
Low temperature brazing filler is generally calledsolder, and is an alloy of tin and lead. Since it isweak in adhesive strength, do not use it forrefrigerant pipes.
Phosphor bronze brazing filler tends to reactwith sulfur and produce a fragile compoundwater solution, which may cause a gas leak-age. Therefore, use any other type of brazingfiller at a hot spring resort, etc., and coat thesurface with a paint.
When performing brazing again at time ofservicing, use the same type of brazing filler.
2-5-2. Flux(1) Reason why flux is necessary
By removing the oxide film and any foreignmatter on the metal surface, it assists the flowof brazing fil ler.
In the brazing process, it prevents the metalsurface from being oxidized.
By reducing the brazing fillers surface tension,the brazing filler adheres better to the treatedmetal.

(2) Characteristics required for flux
Activated temperature of flux coincides with thebrazing temperature.
Due to a wide effective temperature range, fluxis hard to carbonize.
It is easy to remove slag after brazing.
The corrosive action to the treated metal andbrazing filler is minimum.
It excels in coating performance and is harm-less to the human body.
As the flux works in a complicated manner asdescribed above, it is necessary to select anadequate type of flux according to the type andshape of treated metal, type of brazing filler andbrazing method, etc.
(3) Types of flux
Noncorrosive flux
Generally, it is a compound of borax and boric
acid.
It is effective in case where the brazing tem-perature is higher than 800C.
Activated flux
Most of fluxes generally used for silver brazingare this type.
It features an increased oxide film removingcapability due to the addition of compoundssuch as potassium fluoride, potassium chlo-ride and sodium fluoride to the borax-boric acidcompound.

Do not enter flux into the refrigeration cycle.
When chlorine contained in the flux remainswithin the pipe, the lubricating oil deterio-rates. Therefore, use a flux which does notcontain chlorine.
When adding water to the flux, use waterwhich does not contain chlorine (e.g. distilledwater or ion-exchange water).
Remove the flux after brazing.
2-5-3. Brazing
As brazing work requires sophisticated techniques,experiences based upon a theoretical knowledge, itmust be performed by a person qualified.
In order to prevent the oxide film from occurring inthe pipe interior during brazing, it is effective toproceed with brazing while letting dry Nitrogen gas
(N2) flow.
Never use gas other than Nitrogen gas.
(1) Brazing method to prevent oxidation
Attach a reducing valve and a flow-meter tothe Nitrogen gas cylinder.
Use a copper pipe to direct the piping mate-rial, and attach a flow-meter to the cylinder.
Apply a seal onto the clearance between thepiping material and inserted copper pipe forNitrogen in order to prevent backflow of the
Nitrogen gas.
When the Nitrogen gas is flowing, be sure tokeep the piping end open.
Adjust the flow rate of Nitrogen gas so that itis lower than 0.05 m /Hr or 0.02 MPa (0.2kgf/cm) by means of the reducing valve.
After performing the steps above, keep theNitrogen gas flowing until the pipe cools downto a certain extent (temperature at whichpipes are touchable with hands).
Remove the flux completely after brazing.
