Conair UGH016/0500 manual Checking Refrigerant Charge, WARNING Refrigerant hazard, Sight glass

CHECKING

REFRIGERANT

CHARGE

All chillers are fully charged with refrigerant at the factory. Your chiller’s model nameplate identifies the type and amount of total refrigerant charge required.

Check refrigerant charge while the chiller is running. Check the refrigerant charge through the sight glass. Open the side door of the Chiller. Use a flashlight, if necessary, and check the liquid-line sight glass:

●Under normal load conditions, the refrigerant should be clear.

●Under low load conditions, when the hot-gas bypass valves are operating, bubbles may be visible in the sight glass. This is normal.

If the charge is low contact Conair service or have a local, cer- tified refrigeration technician add refrigerant to the system.

WARNING: Refrigerant hazard

Only certified refrigerant technicians should examine and correct problems involving the refrigerant circuit.
