13.13 Compressor Replacement
CAUTION – R-600a REFRIGERANT (ISOBUTANE)
The refrigerant contained within the sealed in system is
flammable.
All care must be taken when servicing
these products. Vent well before brazing. Avoid any open flames or ignition source. The gauges, charging
cylinder and other such equipment used with R-600a must not be used with other refrigerants such as
R-134a, as this could cause cross contamination of the oils used in the systems. Gauges etc. should be
clearly marked to ensure that they are used only for R-600a refrigerant.
1. Disconnect the power cord from wall outlet. Empty the freezer.
2. Recover the refrigerant or vent to atmosphere from the system by fitting a line tap valve to the process
pipe on the compressor and connecting to the recovery unit.
3. Disconnect the electrical harness leads from the relay and overload. (Electric’s must be returned with
the failed compressor).
4. Unbraze the compressor suction, discharge and oil cooler lines. Cut if a blockage suspected.
5. Remove the retaining clips from the compressor mounting pins to lift clear of the unit compartment.
Seal the compressor lines.
6. Fit the new compressor to the mounting pins and place back into the cabinet.
7. Braze in the suction and discharge lines.
8. Replace the filter drier. (Cut from the system, do not heat.)
NOTE:
Do not push the capillary tube too far into the filter or it may become blocked by the filter
screen.
9. Pressurise the system and test for leaks.
