1.4 SAFETY PRECAUTIONS

1.5 INSULATION

1. When servicing, set the ROTARY SWITCH to
Off ( O ) and unplug the power cord.
2. Observe the original lead dress.
If a short circuit is found, replace all parts which

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

have been overheated or damaged by the short
circuit.

RESISTANCE

TEST

between the jumpered lead and each exposed
metallic part on the equipment at all position
[except Off ( 0 )] of the ROTARY SWITCH.
4. The value should be over 1 M_.

3. After servicing, make an insulation resistance test
to prevent the customer from being exposed to
shock hazards.

NOTES
Replacement of the refrigeration cycle.
1. When replacing the refrigerating cycle, be sure to discharge the refrigerant by using a refrigerant recovery system.
2. After discharging the unit completely, remove the desired components, 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. After doing the above procedures, the valve must be closed and left in place on the system for any subsequent
procedures.
6. Evacuate as follows:
6-1. Connect the vacuum pump, as illustrated figure 72A.
6-2. Start the vacuum pump. Slowly open manifold valves A and B with two full turns counterclockwise
the valves closed.

and leave

The vacuum pump is now pulling through valves A and B up to valve C by means of manifold and the 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 counter-clockwise. This will keep oil from foaming and being drawn into the vacuum
pump.
6-3. Operate the vacuum pump for 20 to 30 minutes, until 600 micron 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 remains in the system.
With valves A and B closed, stop the vacuum pump.
6-4. Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 23B. Open valve C.
Discharge the line at the manifold connection.
6-5. The system is now ready for final charging.
7. Recharge as follows :
7-1. Rotary compressor 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 is installed as the system is opened.
7-2. Connect the charging cylinder as shown in figure 72B. With valve C open, discharge the hose at the manifold
connection.
7-3.
7-4.
7-5.
a.
b.
c.

Open valve A and allow the proper charge to enter the system. Valve B is still closed.
If more charge is required, the high-side will not take it. Close valve A.
With the unit running, open valve B and add the balance of the charge.
Do not add the liquid refrigerant to the low-side.
Watch the tow-side gauge, allow pressure to rise to 30 Ibs.
rum off valve B and allow the pressure to drop.

d. Repeat steps B and C until the balance of the charge is in the system.
7-6. When the unit is operating correctly, use the pinch-off tool with the unit stillrunning and the clamp on 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 the pinch-off tube closed. rum off the unit, allow setting for a while and then test the leakage of the pinch-off connection.

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.

• If storm window presents interference, fasten a 2"
wide wood strip to inner window sill across the full
width of the sill. Wood strip should be thick enough
to raise the height of the window sill so that the
unit can be installed without interference by the
storm window frame. See Figure 80.
Top of wood stdp should be approximately 3/4"
higher than storm window frame or wood strip
(OUTDOORS) to help unit condensation to drain
propedy to the outside.
• Install a second wood strip (approximately 6" long
1" wide and same thickness as first strip) in the
center of the outer sill flush against the back of the

Test capacitor.
Replace if not within -t-10% of manufacturer's
rating. Replace if shorted, open, or damaged.

Will not rotate

Fan blade hitting shroud or blower wheel hitting
scroll. Re-align assembly.
Units using slinger ring condenser fans must
have 0.22-0.25 inch clearance to the base. If it is
the base, shim up the bottom of the fan motor
with mounting screw(s).
Check fan motor bearings; if motor shaft will not
rotate, replace the motor.

Fan motor runs.

Check voltage. See limits on this page.

Revolves on overload.

If not within limits, call an electrician.
Test capacitor.
Check bearings. Does the fan blade rotate freely?.
If not, replace fan motor.
Pay attention to any change from high speed to
low speed. If the speed does not change,
replace the motor.

CAUSE

COMPLAINT
Fan motor noise.

REMEDY

If cracked, out of balance, or partially missing,
replace it.

Blower

If cracked, out of balance, or partially missing,
replace it.

Loose set screw

Tighten it.

Worn bearings

If knocking sounds continue when running or
loose, replace the motor. If the motor hums or
noise appears to be internal while running,
replace motor.

Compressor will not run,
fan motor runs.

Voltage

Check voltage. See the limits on the preceding
page. If not within limits, call an electrician.

Wiring

Check the wire connections; if loose, repair or
replace the terminal. If the wires are disconnected, refer to wiring diagram for identification,
and replace the wires. Check the wire connections
If not according to the widng diagram, correct
the connections.

Rotary Switch

Check for continuity, refer to the widng diagram
for terminal identification. Replace the switch if
the circuit is open.

Thermostat

Check the position of knob. If not at the coldest
setting, advance the knob to this setting and
restart the unit.
Check the continuity of the thermostat. Replace
the thermostat if the circuit is open.

Compressor cycles on
ovedoad.

Capacitor (discharge
capacitor before
servicing.)

Check the capacitor.
Replace if not within_+10% of manufacturer's
rating, replace if shorted, open, or damaged.

Compressor

Chock the compressor for open circuit or
ground. If open or grounded, replace the
compressor.

Ovedcad

Check the compressor overloadif extemallymounted.
Replace if open. (If the compressortemperature is
high, remove the overload, cool and retest.)

Voltage

Check the voltage. See the limits on the
preceding page. If voltage is not within these limits
call an electrician.

Ovedoad

Check overload, if externally mounted.
Replace if open. (If the compressor temperature
is high, remove the ovedoad, cool, and retest.)

CAUSE

COMPLAINT
Compressor cycles on
overload

REMEDY

Fan motor

If not running, determine the cause. Replace if
required.

Condenser air flow
restriction

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
re-assembling.

Insufficient cooling.

Excessive noise.

Condenser fins

If the condenser fins are closed over a large

(damaged)

area on the coil surface, head pressures will
increase, causing the compressor to cycle.
Straighten the fins or replace the coil.

Capacitor

Test the capacitor.

Wiring

Check the terminals. If loose, repair or replace.

Refrigeration system

Check the system for a restriction.

Air filter

If restricted, clean or replace.

Unit undersized

Determine if the unit is propedy sized for the
area to be cooled.

Blower or fan

Check the set screw, or clamp. If loose or missing, correct. If the blower or fan is hitting scroll
or shroud, rearrange the air handling parts.
Remove the cabinet and carefully rearrange the
