There is a gravity drain line so that it can not be installed above the evaporator unit. Otherwise a condensation pump must be used.

3. Refrigeration Piping and Charging

NOTES: ALWAYS USE THE SUPERHEAT AND SUBCOOLING, PRESSURE READINGS TO CHARGE REFRIGERANT PROPERLY, THE LISTED CHARGES ARE FOR REFERENCE ONLY.

The installation order starts from condensing unit (including the receiver), liquid line filter-drier, moisture-liquid indicator (sight glass), liquid line, evaporator unit (including liquid line solenoid valve and thermostatic expansion valve or automatic expansion valve), returning to suction line and condensing unit.

The subcooling at the condensing unit shall be around 10°F. The charge may be complete when there are no more bubbles forming in the sight glass.

The evaporator superheat is set around 8-10 °F for a 10 °F TD system at factory.

Low side pressure: around 33 psig

High side pressure: 130 -150 psig at 75 -90 °F ambient temperatures
