Performance Curve Diagram - Toyotomi TAN/TAG-A28EWI Service Manual

REMARKS FOR GAS PRESSURE CHECK AND CHARGING
Gas pressure is to be measured at COMPULSORY COOLING OPERATION for cooling or EMERGENCY
OPERATION for heating. (It is operated for 30 minutes at 58Hz fixed frequency.)
If you find substantial diffrence in performance compared with PERFORMANCE CURVE as shown next,
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.
