Air-Cooled Models—Self-Contained Compressor

Liebert Lee-Temp Receiver Refrigerant Level

On each receiver at the condenser are two refrigerant-level sight glasses. Refrigerant level will vary with outside temperature. Check refrigerant level after the unit has been on for at least 15 minutes.

Sight Glass Levels

40°F (4.5°C) and lower—bottom sight glass is 3/4 full 40 to 60°F (4.5 to 15.5°C)—bottom sight glass is full 60°F (15.5°C) and higher—top sight glass is 3/4 full.
