Filling the appliance
Always fill with liquid.
►
Place the refrigerant cartridge on its head.
►
Open the extraction valve on the refrigerant cartridge and
break the vacuum.
►
Close the blue valve on the fitter aid.
►
Pinch off the dryer service pipe.
►
Remove the filling hose.
►
Apply Loktite or Lokprep to the thread of the Schrader valve.
►
Seal the Schrader valve with the sealing cap.
(This is required as liquid refrigerant may collect at the pressure
connection following the filling process, and when the pressure
connection is disconnected, a fairly large amount of (liquid) refrigerant
could therefore escape. The refrigerant circuit may then be
underfilled).
►
Open the blue valve on the fitter aid again and continue filling.
►
Start the compressor in order to draw in all the refrigerant from
the cartridge.
However, the compressor must not be started until the
vacuum has been broken, otherwise electrical
flashovers may occur.
►
When the compressor is running, wait until the suction
pressure moves significantly in the low pressure range
(approx. 700 mbar). Only then is the R 600A filling cartridge
completely drained.
►
Close the extraction valve on the refrigerant cartridge and the
black valve on the fitter aid.
►
Switch off the compressor.
2.12.2.6 Reseal the repaired R 600A refrigerant circuit
Pinch off the compressor service pipe
Even when the compressor has been switched off,
suction pressure remains in the partial vacuum,
therefore the service pipe must be pinched off
particulary carefully to prevent the refrigerant circuit
from drawing in any air.
►
Remove the filling hose
►
Apply Loktite or Lokprep to the Schrader valve thread
►
Seal the Schrader valve with the sealing cap
