NEO-Plasma Air Purifying System

LG Electronics’ unique neo-plasma air purifying system, equipped with 12-level bio-enzyme filters,

has further enhanced its sterilization power. While air passes each level of filters, the system powerfully eliminates household's fine dust and molds, ordinary odor, food smell, and cigar smoke,

as well as destroy bacterial cell wall thereby completely killing them. It has strong sterilization power.

Though the industrial development has enhanced people's quality of life and their satisfaction in living, it isincreasingly creating various kinds of pollution, hazardous substances and viruses.

In particular, substances (household tick dust, molds, etc.) that create allergies give rise to respiratory diseasesand atopic diseases. Harmful gases, the prime cause of 'new house syndromes,’ create chronic headache.

Auto CleanThe main cause of air conditioner's odor is molds thatbreed in the heatexchanger. If you turn off the air con-ditioner as it is, molds and bacteria will breed in the wetheat exchanger.

The automatic cleaning function will dry the wet heatexchanger to prevent molds and bacteria from breed-ing. This eliminates air conditioner's odor and save youtime from frequent cleaning efforts.

When you press "Auto Clean”, Auto clean starts after

cooling operation.

In 30 minutes, Auto clean" dries the inner

part of Air conditioner.

1STEP : Dries the evaporator with super-weak, low-

noise air blowing, and removes remaining moisture.

2STEP : Fundamentally removes the sources of molds

once again through the neo plasma system.

• Remove odor !• Restrain mildew !• Keep performance ! (Durability)• Save time to clean up.

AfterBefore Effect

Healthy DehumidificationDehumidification mode reduces uncomfortable humidity from the room without over cooling.

Indoor Temperature Distribution Chart

Conventional

Since the surrounding temperature is measured afterthe air from the unit is widely distributed,an accurateassessment of the air is not possible.

LG Healthy Dehumidification

By increasing the Vane Angle,a better assessment ofthe actual temperature is possible to prevent over cool-ing.


Auto ChangeoverWith heat pump model,cooling and heating operation ischanged automatically on the base of setting temp.

• Initial Setting Temp:18˚C Memorize final setting temp.

Hot Start FunctionDuring starting of the unit in the heating mode it pre-vents cold air blowing from the unit. It starts theindoor fan only after indoor unit pipe temperaturereaches a preset value (28˚C).

When indoor unit pipe temperature reaches 28˚C,then for initial 1 minute the indoor fan runs at a lowspeed and after that at the setting speed.

Auto Restart FunctionIn case of a sudden power failure, It automaticallysets the A/C to settings before the power failure whenpower returns.

Sleep Mode Auto ControlWith one touch of the Sleep mode button,

it automatically programs the Air Conditioning Unit toturn off, controls the fan speed and adjusts the settemperature for a more comfortable sleep.


Anti Corrosion Gold Fin™LG ’s Outdoor Heat Exchanger is coated with a golden anti-cor-rosive epoxy treatment on the aluminum coil to minimized cor-rosion. This maintains heat transfer properties of the coil for anextended time where as non-Gold Fin coils progressively loseefficiency due to surface corrosion. Standard on every LG airconditioner, this assists in areas suffering from pollution or nearthe ocean where the unit may subjected to higher levels of salt.

Drive the lower parts after facing the hole of product with plastic anchors, and fix completely the upper screws.

First, drive the two points of the upper parts by screws. (Leave 10mm for hanging product)

Drill the piercing part for connecting pipe as diameter 50mm. (In case of piercing rear surface)


14. Installation

14.1.4 Connection of piping• Preparing the indoor unit's piping and drain hose for instal-

lation through the wall.

1) Route the indoor tubing and the drain hose in thedirection of rear left or right

2) Tape the tubing, drain hose and the connectingcable. Make sure that the drain hose is located atthe lowest side of the bundle. Locating at theupper side can cause drain pan to overflow insidethe unit.

If the drain hose is routed inside the room, insulate the hosewith an insulation material* so that dripping from condensa-tion will not damage furniture or floors.

*Foamed polyethylene or equivalent is recommended.

3) Connecting the pipings to the in door unit anddrain hose to drain pipe

Align the center of the pipings and sufficiently tighten theflare nut by hand.

Tighten the flare nut with a wrench.

When extending the drain hose at the indoor unit, installthe drain pipe.

4) Wrap the insulation material around the connect-ing portion.

Overlap the connection pipe insulation material and theindoor unit pipe insulation material. Bind them togetherwith vinyl tape so that there is no gap.NOTE

14.3 Flaring workMain cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.

1) Cut the pipes and the cable.Use the piping kit accessory or the pipes purchasedlocally.

Measure the distance between the indoor and the out-door unit.

Cut the pipes a little longer than measured distance.

Cut the cable 1.5m longer than the pipe length.

2) Burrs removalCompletely remove all burrs from the cut cross sectionof pipe/tube.

Put the end of the copper tube/pipe in a downward direc-tion as you remove burrs in order to avoid dropping ofburrs into the tubing.

3) Putting nut onRemove flare nuts attached to indoor and outdoor unit,then put them on pipe/tube having completed burrremoval.(not possible to put them on after flaring work)

4) Flaring workCarry out flaring work using flaring tool as shown below.

Firmly hold copper pipe in a die in the dimension shownin the table below.

5) Check after flaringCompare the flared work with figure on right side.

9)• Check for gas leaks.

(Check at the threaded section of the flare nut for gas leak)

• Spay –type gas leak detecting products are available on the market.

• Soap water may be used to check for leaks , but use only neutral soap to prevent corrosion of the flare nut.

• Be sure to wipe the nut area clean after the gas leak check.

8) Tighten the flare nut. (Use a torque wrench to apply the proper tightening force)

7) Apply refrigerant oil on the inside and outside of the flared section.

(Do not apply SUNISO oil) (Be careful to keep dust away)

6) Flare the pipe. Rotate the flaring tool 3 or 4 turns after a clicking sound is produced. this results in a clean flared surface

1) Cut the pipe using a pipe cutter.

2) The cut edge has burrs. (the amount of burrs becomes larger when pipe wall is thick)

3) Remove the burrs using a reamer (Be careful not to let particles enter the pipe. Point the pipe end downward during cutting)

4) Clean the inside of the pipe (use a thin stick with a cloth wrapped around it)

5) Before flaring , clean the cone section of the flaring tool.

Air purgingThe air and moisture remaining in the refrigerant system have undesirable effects as indicated below.

1. Pressure in the system rises.2. Operating current rises.3. Cooling(or heating) efficiency drops.4. Moisture in the refrigerant circuit may freeze and block capillary tubing.5. Water may lead to corrosion of parts in the refrigeration system.Therefore, after evacuating the system, take a leak test for the piping and tubing between the indoor and outdoorunit.

Air purging with vacuum pump1. Preparation

• Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units have been properly connectedand all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side onthe outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage.

2. Leak test

• Connect the manifold valve(with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses.

Be sure to use a manifold valve for air purging. If it is not available, use a stop valve for this purpose. The "Hi"knob of the manifold valve must always be kept close.• Pressurize the system to no more than 150 P.S.I.G. with dry nitrogen gas and close the cylinder valve when the

gauge reading reached 150 P.S.I.G. Next, test for leaks with liquid soap.

To avoid nitrogen entering the refrigerant system in a liquid state, the top of the cylinder must be higher than itsbottom when you pressurize the system. Usually, the cylinder is used in a vertical standing position.

1. Do a leak test of all joints of the tubing(both indoorand outdoor) and both gas and liquid side servicevalves.Bubbles indicate a leak. Be sure to wipe off thesoap with a clean cloth.

2. After the system is found to be free of leaks,relieve the nitrogen pressure by loosening thecharge hose connector at the nitrogen cylinder.When the system pressure is reduced to normal,disconnect the hose from the cylinder.

Soap water method1. Remove the caps from the 2-way and 3-way valves.2. Remove the service-port cap from the 3-way valve.3. To open the 2-way valve turn the valve stem counterclock-

wise approximately 90°, wait for about 2~3 sec, and close it.4. Apply a soap water or a liquid neutral detergent on the

indoor unit connection or outdoor unit connections by a softbrush to check for leakage of the connecting points of thepiping.

5. If bubbles come out, the pipes have leakage

Evacuation1. Connect the charge hose end described in the preceding

steps to the vacuum pump to evacuate the tubing andindoor unit.Confirm the "Lo" knob of the manifold valve is open.Then, run the vacuum pump.The operation time for evacuation varies with tubinglength and capacity of the pump. The following tableshows the time required for evacuation.

2. When the desired vacuum is reached, close the "Lo"knob of the manifold valve and stop the vacuum pump.

Finishing the job1. With a service valve wrench, turn the valve stem of liquid

side valve counter-clockwise to fully open the valve.2. Turn the valve stem of gas side valve counter-clockwise

to fully open the valve.3. Loosen the charge hose connected to the gas side ser-

vice port slightly to release the pressure, then removethe hose.

4. Replace the flare nut and its bonnet on the gas side ser-vice port and fasten the flare nut securely with anadjustable wrench. This process is very important to pre-vent leakage from the system.

5. Replace the valve caps at both gas and liquid side ser-vice valves and fasten them tight.

This completes air purging with a vacuum pump. The air conditioner is now ready to test run.
