careful of the liquid refrigerant).
3. Open the valve (Low side) on the charge set and charge
the system with liquid refrigerant.
•
If thesyste m cannot becharge d with thespe cifie d
amount of refrigerant, it can be charged with a little at a
time (approximately 150 g each time) while operating
the air conditioner in the cooling cycle; however, one
timeis not sufficient, wait approximately 1 minuteand
then repeat the procedure. (pumping down-pin)
This is different from previous procedures. Because you are
charging with liquid refrigerant from the gas side, absolutely do
no attempt to charge with large amount of liquid refrigerant
while operating the air conditioner.
4. Immediately disconnect the charge hose from the 3-
way valve’s service port.
•
Stopping partway will allow the refrigerant to be
discharged.
•
If the system has been charged with liquid refrigerant
while operating the air conditioner, turn off the air
conditioner before disconnecting the hose.
5. Mount the valve stem caps and the service port cap.
•
Use torque wrench to tighten the service port cap to a
torqueof 18 N.m.
