NOTICE
— Replacement of the refrigeration cycle.
6. Recharge as follows :
1. When replacing the refrigeration cycle, be sure to
TM
Discharge the refrigerant system using a Freon
recovery System.
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
30B.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
TM
the Freon . 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.
With valve C open, discharge the hose at the
manifold connection.
3. Braze service valves into the pinch-off tube ports,
leaving the valves open.
4. Braze the pinch-off tubes with Service valves.
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. Evacuate as follows.
1) Connect the vacuum pump, as illustrated figure
30A.
5) With the unit running, open valve B and add the
balance of the charge.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns counterclock-
wise and leave the valves open.
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.
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 counterclockwise.
This will keep oil from foaming and being
drawn into the vacuum pump.
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 brazing 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.
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
30B.
Open valve C.
Discharge the line at the manifold connection.
5) The system is now ready for final charging.

COMPLAINT
CAUSE
REMEDY
Fan motor will not run.
No power
Check voltage at outlet. Correct if none.
Power supply cord

Replace if not within ±10% of manufacturer's rating.
Replace if shorted, open, or damaged.
Will not rotate
Fan blade hitting shroud or blower wheel hitting
scroll. Realign assembly.
Units using slinger ring for condenser fan must have
1/4 to 5/16 inch clearance to the base. If it hits 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
intermittently
Check voltage. 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

Check the capacitor.
capacitor before servicing.) Replace if not within ±10% of manufacturers rating.
Replace if shorted, open, or damaged.
Compressor
Check the compressor for open circuit or ground. If
open or grounded, replace the compressor.

Condenser air flow restric-
tion
Remove the cabinet. inspect the interior surface of
the condenser; if restricted, clean carefully with a vac-
uum cleaner (do not damage fins) or brush. Clean the
interior base before reassembling.
Condenser fins (damaged) 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.
Capacitor
Test capacitor.
Compressor cycles on
overload.
Wiring
Check the terminals. If loose, repair or replace.
Check the system for a restriction.
If restricted, clean of replace.
