DRAINING - FILLING - BLEEDING REFRIGERANT CIRCUIT

1 - DRAINING

(1) high pressure valve .

(2) low pressure valve .

NOTE : the high pressure valve is fitted on the tube with the smallest diameter .

Drain the circuit via the low pressure valve (gaseous zone), very slowly to avoid draining the compressor oil .

2 - REFILLING

IMPERATIVE : before filling the circuit with refrigerant, it is necessary to carry out a vacuum extraction to dry the circuit .

Connect the filling equipment to the service valves .

Carry out a vacuum extraction (Draining time : 15 minutes). .

Check the sealing of the circuit : The vacuum should be held for more than 5 minutes. .

Carry out a pre-filling : 300 g .

Check the sealing of the circuit .

Drain the refrigerant circuit .

Carry out a vacuum extraction (Draining time : 30 minutes Minimum). .

Charge the circuit with the specified quantity of refrigerant .
