1. PREFACE
This SERVICE MANUAL provides various service information, including the mechanical and electrical
parts etc. This room air conditioner was manufactured and assembled under a strict quality control system.
The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.
1.1 SAFETY PRECAUTIONS
1. When servicing the unit, turn off the air conditioner
and unplug the power cord.
2. Observe the original lead dress.
If a short circuit is found, replace all parts which
have been overheated or damaged by the short
circuit.
3. After servicing the unit, make an insulation
resistance test to protect the customer from being
exposed to shock hazards.
1.2 INSULATION RESISTANCE TEST
1. Unplug the power cord and connect a jumper
between 2 pins (black and white).
2. The grounding conductor (green or green & yellow)
is to be open.
3. Measure the resistance value with an ohm meter
between the jumpered lead and each exposed
metallic part on the equipment.
4. The value should be over 1M .

NOTICE
-Replacement of the refrigeration circuit.
1. When replacing the refrigeration circuit, 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 unbraze 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 figure
33A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns counterclock-
wise and leave the valves open.
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 equip-
ment is used, just crack valves A
and B for a few minutes, then open
slowly with the two full turns counter-
clockwise. This will keep oil from foaming
and being drawn into the vacuum pump.
3) Operate the vacuum pump vaccum for 20 to 30
minutes, until 600 microns of vaccum is
obtained. Close valves A and B, and observe
vacuum gauge for a few minutes. A rise in pres-
sure 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 figure
37B. Open valve C.
Discharge the line at the manifold connection.
5) The system is now ready for final charging.
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 figure
33B.
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 Low-side.
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 braze and braze
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.
