1.4 SAFETY PRECAUTIONS  
1.5 INSULATION RESISTANCE TEST  
1. When servicing, set the ROTARY SWITCH to  
Off and unplug the power cord.  
1. Unplug the power cord and connect a jumper  
between 2 pins (black and white).  
2. Observe the original lead dress.  
If a short circuit is found, replace all parts which  
have been overheated or damaged by the short cir-  
cuit.  
3. After servicing, make an insulation resistance test  
to prevent the customer from being exposed to  
shock hazards.  
2. The grounding conductor (green or green and yel-  
low) is to be open.  
3. Measure the resistance value with an ohm meter  
between the jumpered lead and each exposed  
metallic part on the equipment at all position  
[except Off] of the ROTARY SWITCH.  
4. The value should be over 1 M.

utes, 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 remaining in the system.  
With valves A and B closed, stop the vacuum  
pump.  
5. Remove the proper coil.  
6. Re-install by referring to the procedures above.  
6-4. Remove the hose from the vacuum pump and

7-1. 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 is  
installed as the system is opened.  
7-2. Connect the charging cylinder as shown in fig-  
ure 21B. With valve C open, discharge the  
hose at the manifold connection.  
NOTES  
7-3. Open valve A and allow the proper charge to  
enter the system. Valve B is still closed.  
7-4. If more charge is required, the high-side will  
not take it. Close valve A.  
7-5. With the unit running, open valve B and add  
the balance of the charge.  
Replacement of the refrigeration cycle.  
1. When replacing the refrigeration 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 completing the above procedures, the valve  
must be closed and left in place on the system for  
any subsequent procedures.  
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 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 still running and  
clamp on the pinch-off tube. Using a tube cut-  
ter, cut the pinch-off tube about 2 inches from  
the pinch-off . Use sil-fos solder and solder  
the pinch-off tube closed. Turn off the unit,  
allow unit to sit for a while and then test the  
leakage of the pinch-off connection.  
6. Evacuate as follows:  
6-1. Connect the vacuum pump, as illustrated in  
figure 21A.  
6-2. Start the vacuum pump. Slowly open manifold  
valves A and B with two full turns counter-  
clockwise and leave the valves closed.  
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 counterclock-
