6. Recharge as follows :
servicing the 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.
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.
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
30A.
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.
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.
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.
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.
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

Troubleshooting Guide
COMPLAINT
CAUSE
REMEDY
Compressor cycles on
overload.
Voltage
Check the voltage. See the limits on the
preceding page. If voltage is not within these limits,
call an electrician.
Overload
Check overload, if externally mounted.
Replace if open. (If the compressor temperature
is high, remove the overload, cool, and retest.)
Compressor cycles on
overload.
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.
Condenser fins
(damaged)
If the condenser fins are closed over a large
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.
Check the system for a restriction.
If restricted, clean or replace.
Refrigeration system
Air filter
Insufficient cooling
Excessive noise
Unit undersized
Blower or fan
Determine if the unit is properly sized for the
area to be cooled.
Check the set screw, or clamp. If loose or miss-
ing, correct. If the blower or fan is hitting scroll
or barrier, rearrange the air handling parts.
Copper tubing
Remove the cabinet and carefully rearrange the
tubing not to contact the cabinet,
compressor, shroud, and barrier.
