Refrigerant amount

Before shipment, this air conditioner is filled

with the rated amount of refrigerant including

additional amount required for air-purging,

subject to 7.5m piping length. (The rated amount

of refrigerant is indicated on the name plate.)

But when the piping length exceeds 7.5 meters,

additional charge is required according to the

following table.

Example:

In case of 10m long pipe(one-way), the amount

of refrigerant to be replenished is:

(10 - 7.5) x 70 = 175g

Installation of Unit

Preparation of Piping

Main cause of gas leakage is defect in flaring

work. Carry out correct flaring work in the

following procedure.

1. Cut the pipes and the cable.

• Use the accessory piping kit or the pipes

purchased locally.

• Measure the distance between the indoor

and the outdoor unit.

• Cut the pipes a little longer than measured

distance.

•

Cut the cable 1.5m longer than the pipe

length.

2. Burrs removal

• Completely remove all burrs from the cut

cross section of pipe/tube.

•

Put the end of the copper tube/pipe to

downward direction as you remove burrs in

ord

er to avoid to let burrs drop in the tubing.

3. Putting nut on

• Remove flare nuts attached to indoor and

outdoor units, than put them on pipe/tube

having completed burr removal.

(Not possible to put them on after flaring work)

4. Flaring work

•

Carry out flaring work using dedicated

flaring tool for R-22 as shown below.

Firmly hold copper tube in a bar(or die) as

indicated dimension in the table above.

5. Check

• Compare the flared work with figure below.

• If flare is noted to be defective, cut off the

flared section and do flaring work again.

Connection of piping

• Align the center of the pipings and suffciently

tighten the flare nut with fingers.

• Finally, tighten the flare nut with troque

wrench until the wrench clicks.

When tightening the flare nut with troque

wrench, ensure the direction for tightening

follows the arrow on the wrench.

1.

If it is necessary to bend or stretch the

tubing, use the spring which is attached to

the tubing in stead of pipe bender.

• Please make a careful notice to make a

smooth line.

• Hold the tubing with your two hands closely

and then bend or stretch it slowly not to

make any crack.

• Remember that the radius (R) should not

exceed 70mm (Refer to Fig. 1)

2. Do not repeat the bending process to prevent

the tubing from cracking or crushing.

3. Keep in mind that the bending part should

not be cracked and make the radius (R) as

long as possible (Refer to Fig. 2)

Power Supply and Wiring

The unit is completely wired internally at the

factory according to general rule of electrical

technology, but local rules, if they are required,

should be complied with.

1. Power supply

Power source must fulfill the following

conditions:

• The working voltage should be higher than

90% and lower than 110% of the rated

voltage marked on the name plate.

• The starting voltage should be higher than

85% of the rated voltage marked on the

name plate.

Starting voltage

• Provide a recognized circuit breaker as

below between power source and unit.

A disconnection device to adequately

disconnect all supply lines must be fitted.

(for service operations)

• The screws which fasten the wiring in the

casing of electrical fittings are liable to

come loose from vibrations to which the

unit is subjected during the course of

transportation. Check them and make sure

that they are all tightly fastened.

(If they are loose, it could give rise to burn-

out of the wires.)

• See to it that the starting voltage is

maintained at more than 90 percent of the

rated voltage marked on the name plate.

• The following troubles would be caused by

voltage drop-down.

Vibration of a magnetic switch, damage on

the contact point there of, fuse breaking,

disturbance to the normal function of a

overload protection device.

2. Wiring

After the confirmation of the above conditions, prepare the wiring as follows:

Vacuum Drying of the Connecting Pipes and the Indoor Unit

The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the

compressor.

1. Confirm that both the liquid side valve and the gas side valve are set to the closed position.

2. After connecting the piping, check the joints for gas leakage with gas leak detector.

3. Remove the service port nut, and connect the gauge manifold and the vacuum pump to the service

port by the charge hose.

4. Vacuum the indoor unit and the connecting pipes until the pressure in them lowers to below -

76cmHg.

5. Remove the valve stem nuts, and fully open the stems of the 2-way and 3-way valves with a hexagon

wrench.

6. Tighten the valve stem nuts of the 2-way valve and 3-way valve.

7. Disconnect the charge hose and fit the nut to the service port.

Form the Piping

1. Wrap the connecting portion of indoor unit

with the insulation material and secure it with

two Plastic Bands. (for the right piping)

• If you connect an additional drain hose,

the end of the drain-outlet should be kept

distance from the ground. (Do not dip it

into water, and fix it on the wall to avoid

swinging in the wind.)

2. Tape the Piping, and Connecting Cable from

down to up.

3. Form the piping gathered by taping along the

exterior wall and fix it onto the wall by saddle

or equivalent.

1. Tape the piping and connecting cable from

down to up.

2. In order to prevent water from entering the

room, form a trap and tape the piping.

3. Fix the piping onto the wall with saddle or

bracket.

Installation guide at the seaside

In case, to install the outdoor unit on the sea-

side, set up a windbreak not to be exposed to

the sea wind.

Select a well-drained place.

- It should be strong enough like concrete to

prevent the sea wind from the sea.

- The height and width should be more than

150% of the outdoor unit.

- It should be keep more than 70 cm of space

between outdoor unit and the windbreak for

easy air flow.

CAUTION

- Air conditioners should not be installed

in areas where corrosive gases, such as

acid or alkaline gas, are produced.

- Do not install the product where it could

be exposed to sea wind (salty wind)

directly. It can result corrosion on the

product. Corrosion, particularly on the

condenser and evaporator fins, could

cause product malfunction or inefficient

performance.

- If outdoor unit is installed close to the

seaside, it should avoid direct exposure

to the sea wind. Otherwise it needs

additional anticorrosion treatment on the

heat exchanger.

!

Sea wind

Windbreak

Selecting the location(Outdoor Unit)

If the outdoor unit is to be installed close to

the seaside, direct exposure to the sea wind

should be avoided. Install the outdoor unit on

the opposite side of the sea wind direction.

NOTE

!

- If you can’t meet above guide line in

the seaside installation, please con-

tact LG Electronics for the additional

anticorrosion.

- Periodic ( more than once/year )

cleaning of the dust or salt particles

stuck on the heat exchanger by using

water

Do not use sea water when you clean

up the heat exchanger.

Final Check and Test Run

Installation Manual 19

After installing the unit, perform the final check

and running test as follows:

Final check points

Is the unit securely mounted?

Is the installation location adequate?

Is the water piping work adequately and

without leakage?

Are trapped drain lines installed at

condensate drain connections?

Has the refrigeration cooling cycle been

kept sealed?

Is the electrical wiring adequate and are

the screws tightened on terminals?

After the above final checkings, prepare the

running test as follows:

Connect compound gauges to the check

joints at discharge and suction sides of

the compressor.

Turn all switches "OFF".

Turn the main switch "ON".

Running test should be accomplished as follows:

Set operation switch at "FAN" and the fan

will start. Check to ensure that the fan

sounds normal.

Next, set it at "COOL" and the

compressor will start. Check to ensure

that the compressor sounds normal.

Check discharge and suction pressure on

the compound gauges.

Check working voltage, phase balance

and running current.

Check to ensure that the thermistor

functions properly.

Check to ensure that the high pressure

control switch functions correctly.
