Installing A New Compressor - Electrolux E23CS75DSS0 Service Manual

Section E - Refrigeration System
NOTE
To flush evaporator and heat exchanger you
must remove evaporator from inside product to
disconnect cap tube.
4. Disconnect capillary tube from evaporator.
Flush evaporator in same manner as
condenser.
5. Flush cap tube. This is only possible if you
have proper service valve adaptor.
6. Reassemble system.

Installing a New Compressor

NOTE
Entirely new compressors have been developed
for use with R-134a and Ester oil refrigeration
systems. Both compressor and electric motor
have been modified. Old compressors intended
for R-12 refrigerant must not be used for new
systems charged with R-134a.
Replacement of compressor and installation of
filter-drier must be done in a continuous sequence
so system is exposed to atmosphere no longer
than necessary.
All replacement compressors are shipped with
rubber plugs in the suction, discharge and process
tubes and contain the correct oil charge and a
holding charge of inert gas. Compressors have a
low-side process tube attached to the compressor
shell. A high-side process tube is attached to the
filter-drier.
WARNING
Do not operate reciprocating compressor
when charging liquid refrigerant into system
through its process tube.
Replacement compressors for refrigerator may
have an oil cooler even if the original compressor
did not. If the product is not equipped for an oil
cooler, leave the plastic caps in place and install
the compressor connecting only to the suction and
discharge lines of the new compressor.
Before installing the replacement compressor
remove the discharge plug and check for the pop
sound of the inert gas leaving the compressor.
CAUTION
DO NOT use compressor if you do not
hear this sound.
If the compressor checks OK, reinstall the plug.
Do not remove any of the plugs again until the
compressor is in position and you are ready to
braze the lines.
CAUTION
On R-134a systems, compressor must NOT
be left open to atmosphere for more than 10
minutes to prevent moisture contamination of
oil.
A new compressor which is cold (e.g. after having
been kept in a cold service van) should be left to
warm to the surrounding temperature before the
plugs on the compressor connections are removed.
This will help prevent condensation from forming in
the oil and the compressor. Also, avoid opening the
system when any of the components or lines are
cold.
NOTE
Release holding charge (release slowly to avoid
oil discharge) on new compressor to ensure there
is no leak in seam or tubing. Reinstall rubber plug.
1. Disconnect electrical supply to refrigerator.
2. Remove compressor access panel.
3. Recover refrigerant by using EPA approved
recovery system.
4. Remove condenser fan mounting screws.
5. Unplug fan motor harness located in back of
fan motor.
6. Remove fan motor and fan blade.
7. Remove leads from compressor motor
terminals.
8. Remove mounting clips and washers.
