PERFORMANCE CURVE DIAGRAM
REMARKS FOR GAS PRESSURE CHECK AND CHARGING
Gas pressure is to be measured at COMPULSORY COOLING OPERATION for cooling or EMERGENCY
OPERATION for heating.
If you find substantial difference in performance compared with PERFORMANCE CURVE as shown above,
recharge the refrigerant.
(In order to avoid excessive charging purge all the remaining refrigerant first and then evacuate the unit
completely with vacuum pump and finally apply rated volume charging of refrigerant.)
Charging of refrigerant should be done by cooling operation, because the pressure at service valve will be
too high at heating cycle, then the heating performance characteristics must be checked by restarting of
heating operation.
