1. Remove the cabinet. (Refer to section 2.1.2)
2. Remove the reversing coil from the reversing valve

assembly by loosening the screw.

3. Discharge the refrigerant system using a Freon

TM

recovery system.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the Freon

TM

.

Leave the valve in place after servicing.

4. After discharging the refrigerant completely,

unbraze the interconnecting tube at the reversing
vlave assembly connections.

5. Re-install the components by referring to the

removal procedure, above.

When connect the reversing valve assembly,
braze the reversing valve and inter-connecting
tube immersing in water not to make the tempera-
ture of surface exceed more than 120°C(248°F)

Discharge the refrigerant system using a
Freon

TM

Recovery System.

If there is no valve to attach the recovery sys-
tem, install one (such as a WATCO A-1) before
venting the Freon

TM

. Leave the valve in place

after servicing the system.

— Replacement of the refrigeration cycle.

1. When replacing the refrigeration cycle, be sure to

discharge the refrigerant system using a Freon

TM

recovery System.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the Freon

TM

. Leave the valve in place after servic-

ing 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. Evacuate as follows.

1) Connect the vacuum pump, as illustrated Figure

18A.

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 vaccum 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 
18B.
Open valve C.
Discharge the line at the manifold connection.

5) The system is now ready for final charging.

5. Recharge as follows :

1) Refrigeration cycle systems are charged from 

the High-side. If the total charge can not 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 

18B.
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.

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.

Equipment needed: Vacuum pump, Charging cylinder, Manifold gauge, Brazing equipment. Pinch-off tool capa-
ble of making a vapor-proof seal, Leak detector, Tubing cutter, Hand Tools to remove components, Service valve.
