Conair UGH016/0500 manual Checking The Refrigerant Charge, WARNING Refrigerant hazard

CHECKING THE

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.

WARNING: Refrigerant hazard

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

Check refrigerant charge while the chiller is running:

Check the refrigerant charge through the sight glass.

Use a flashlight, if necessary, and check the liquid-line sight glass:

●Under full load conditions, the refrigerant should be clear (no bubbles).

●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 to add refrigerant to the system.
