NEW COMPRESSOR INSERTION
By using 4 screws fix the new compressor to motor base (wrench n°10) and then screw compressor box
(screwdriver).
After secure the compressor to the base, solder the discharge and suction piping, then also solder the
capillary tube onto the filter after cutting it diagonally and fitting it in by max. 3cm. Solder the pipe exiting
the condenser to the filter inlet. When the circuit is closed, charge the circuit with helium/nitrogen up to a
pressure of 8 bar. Close the circuit to hold the pressure in, then search for circuit leaks using a leak
detector. Adjust the sensitivity of the electronic leak detector (when available) and test each and every
soldering. The sensor will beep when a leak is found. Connect the vacuum pump to the compressor and
filter service intakes and hold the vacuum for at least 30-40minutes (value depending on pump features).
The vacuum degree to be achieved is below 15 Pa or 0,15 mbar .
WARNING! Wrong vacuum execution may cause problems on the refrigerator performance.

HIGH PRESSURE PIPE CLOSING
After 30-40 minut of vacuum operation, disconnect the vacuum machine only on the high
pressure pipe (
