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 .
