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.
CONTENTS

.
1.1 SAFETY PRECAUTIONS
1. When servicing, turn the unit Off 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, make an insulation resistance test to
prevent 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 and 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 equip-
ment at each working status.
4. The value should be over 1 MΩ.

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. Remove the valve
when finished.
CAUTION
—11—
— 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. Remove the valve when finished.
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
16A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns
counterclockwise 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.
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 figure
16B.
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
16B.
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 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.
NOTES
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.
2.4.3 CAPILLARY TUBE
1. Remove the cabinet. (Refer to section 2.1.2)
2. After discharging the refrigerant completely,
unbraze the interconnecting tube at the capillary
tube.(See caution on previous page)
3. Remove the capillary tube.
4. Re-install the components by referring to notes.
CAUTION

Replace if open. (If the compressor temperature is
high, remove the overload, cool, and retest.)
If not running, determine the cause. Replace if
required.
Remove the cabinet. inspect the interior surface of
the condenser; if restricted, clean carefully with a
vacuum cleaner (do not damage fins) or brush.
Clean the interior base before reassembling.
If condenser fins are closed over a large area on the
coil surface, head pressures will increase, causing
the compressor to overload. Straighten the fins or
replace the coil.
Test capacitor.
Check the terminals. If loose, repair or replace.
Check the system for a restriction.
If restricted, clean of replace.
Close if open.
Determine if the unit is properly sized for the area to
be cooled.
Check the set screw or clamp. If loose or missing,
correct. If the blower or fan is hitting air guide,
rearrange the air handling parts.
Remove the cabinet carefully and rearrange tubing
not to contact cabinet, compressor, shroud, and
barrier.
