9. Connect the process - tube - fitting with the suction pipe by wrenches.
10. Connect the charge cylinder (for HFC-134a) with the process - tube - fitting.
11.
12. Leave it until liquid surface in the glass tube of charge cylinder is stabilized (for approx. 10~20 seconds).
13.
14. Collect the liquid in the container and see how stained the discharge liquid.
15. If discharged liquid is stained, repeat the purging at low - pressure side.
16. When pipe cleaning at low - pressure side is finished, disconnect the process - tube fitting from the suction
pipe.
Connect the process - tube - fitting with the inlet
pipe of dryer by wrenches.
Do not purge the pipe at high - pressure side from
compressor side so that no deteriorated oil can
flow into the condenser.
Connect the charge cylinder (for HFC-134a) with
the process - tube - fitting.
Place a container at the inlet of discharge pipe
firmly.
When pipe - cleaning at high - pressure side is
finished, disconnect the process - tube - fitting from
the inlet pipe of dryer.
Close the valve of charge cylinder when liquid come
out.
Collect the liquid in the container and see how
stained the discharged liquid (the inside).
In case that the pressure at the charge cylinder is
low, refrigerator may not come out as liquid.
If the inside is not cleaned yet, repeat purging until
the inside is completely cleaned.
Open the valve of charge cylinder and pinch - off the end of cappilary tube when the refrigerant start
discharging.
Cut the end of capillary tube with capillary tube cutter and place a container at outlet.
