Service Manual 13  
Disassembly Instructions  
NOTICE  
Replacement of the refrigeration cycle.  
6. Recharge as follows :  
1. When replacing the refrigeration cycle, be sure to  
discharge the refrigerant system using a FreonTM  
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 Fig. 17B.  
With valve C open, discharge the hose at the man-  
ifold 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.  
If there is no valve to attach the recovery system,  
install one (such as a WATCO A-1) before venting  
the FreonTM. Leave the valve in place after  
servicing the system.  
2. After discharging the unit completely, remove the  
desired component, and unbrace 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 Fig.  
17A.  
2) Start the vacuum pump, slowly open manifold  
valves A and B with two full turns counterclock-  
wise and leave the valves closed.  
a. Do not add the liquid refrigerant to the Low-  
side.  
b. Watch the Low-side gauge; allow pressure to  
rise to 39 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.  
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.  
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 counterclockwise.  
This will keep oil from foaming and being  
drawn into the vacuum pump.  
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 Fig. 17B.  
Open valve C.  
Discharge the line at the manifold connection.  
5) The system is now ready for final charging.

In general, possible trouble is classified in two causes.  
The one is called Starting Failure which is caused from an electrical defect, and the other is Ineffective Air  
Conditioning caused by a defect in the refrigeration circuit and improper application.
