ELECTRICAL SERVICE
Check your available electrical service. The power
supply available must be the same as that shown on
the unit nameplate (found on left side of cabinet).
All models are equipped with a 3-prong service plug to
provide proper service and safe positive grounding. Do
not change plug in any way. Do not use an adapter
plug. If your present wall outlet does not match your
plug, call a qualified electrician to make the necessary
corrections. SAVE CARTON for storage and this
OWNER'S MANUAL for future reference. The carton is
the best way to store unit during winter or when not in
use.

carrying techniques when moving unit.
• Carefully inspect location where air conditioner will
be installed. Be sure it will support the weight of the
unit over an extended period of time.
• Handle air conditioner with care. Wear protective
gloves whenever lifting or carrying the unit. AVOID
the sharp metal fins of front and rear coils.
• Make sure air conditioner does not fall during installation.

NOTICE
We strongly recommend the removal of the old wall
sleeve and the installation of a new LGE Wall Sleeve.
If you decide to keep the existing wall sleeve, you have
to redirect the louvers at the back of the wall sleeve illustration. The use of pliers is recommended. If you DO
NOT redirect, you run the risk of poor performance or
product failure. This is not covered under the terms of the
LGE warranty.
• Pick a location which will allow the conditioned air to
blow into the area you want. Good installation with
special attention to the proper position of the unit will
lessen the chance that service will be needed.

Disassembly Instructions
NOTICE
— Replacement of the refrigeration cycle.
1. When replacing the refrigeration cycle, be sure to
discharge the refrigerant system using a FreonTM
recovery System.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the FreonTM. Leave the valve in place after
servicing the system.
2. After discharging the unit completely, remove the
desired component, and unbrace the pinch-off
tubes.
3. Solder service valves into the pinch-off tube ports,
leaving the valves open.
4. Solder the pinch-off tubes with Service valves.
5. Evacuate as follows.
1) Connect the vacuum pump, as illustrated Fig.
40A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns counterclockwise and leave the valves closed.
The vacuum pump is now pulling through valves
A and B up to valve C by means of the manifold
and entire system.
CAUTION
If high vacuum equipment is used, just crack
valves A and B for a few minutes, then open
slowly with the two full turns counterclockwise.
This will keep oil from foaming and being
drawn into the vacuum pump.
3) Operate the vacuum pump for 20 to 30 minutes,
until 600 microns of vacuum is obtained. Close
valves A and B, and observe vacuum gauge for
a few minutes. A rise in pressure would
indicate a possible leak or moisture remaining in
the system. With valves A and B closed, stop
the vacuum pump.
4) Remove the hose from the vacuum pump and
place it on the charging cylinder. See Fig. 40B.
Open valve C.
Discharge the line at the manifold connection.
5) The system is now ready for final charging.
22 Room Air Conditioner
6. Recharge as follows :
1) Refrigeration cycle systems are charged from the
High-side. If the total charge cannot be put
in the High-side, the balance will be put in the
suction line through the access valve which you
installed as the system was opened.
2) Connect the charging cylinder as shown in Fig. 40B.
With valve C open, discharge the hose at the manifold connection.
3) Open valve A and allow the proper charge to
enter the system. Valve B is still closed.
4) If more charge is required, the high-side will not
take it. Close valve A.
5) With the unit running, open valve B and add the
balance of the charge.
a. Do not add the liquid refrigerant to the Lowside.
b. Watch the Low-side gauge; allow pressure to
rise to 30 lbs.
c. Turn off valve B and allow pressure to drop.
d. Repeat steps B and C until the balance of the
charge is in the system.
6) When satisfied the unit is operating correctly,
use the pinch-off tool with the unit still running
and clamp on to the pinch-off tube. Using a tube
cutter, cut the pinch-off tube about 2 inches from
the pinch-off tool. Use sil-fos solder and solder
pinch-off tube closed. Turn off the unit, allow it to
set for a while, and then test the leakage of the
pinch-off connection.
Disassembly Instructions
Equipment needed: Vacuum pump, Charging cylinder, Manifold gauge, Brazing equipment. Pinch-off tool capable of making a vapor-proof seal, Leak detector, Tubing cutter, Hand Tools to remove components, Service valve.
