7 Method to Supplement or Discharge Refrigerant

7.1 Supplement Refrigerant

Refrigerant supplementary method for unitary air source water heater is to

supplement directly under hot water mode.

Firstly, connect the hose in refrigerant pressure gauge to the refrigerant bottle,

and connect one side of blue hose in low pressure gauge to fluorine filling nozzle of
air valve (not tight up), then open the valve of refrigerant bottle, reopen the valve
near the low pressure gauge, relief air for 5s then shut down, immediately tight up
the hose connector of fluorine filling nozzle. When pointer of low pressure gauge
declines slowly, unscrew the valve near low pressure gauge for replenishment
(refrigerant supplementary diagram is as Figure 7-1 shows).
