Heat Controller, Inc.
REFRIGERANT ChARGE
1. Refrigerant charge is extremely critical. Measure charging amount carefully -- as exact as possible to the
nameplate amount.
2. The correct method for charging the rotary compressor is to introduce liquid refrigerant into the high side of
the system with the unit off. Then start compressor and enter the balance of the charge, gas only, into the
low side.
The introduction of liquid into the low side, without the use of a capillary tube, will cause damage to the discharge
valve of the rotary compressor.
