Mounting The "Liquid Injection" Extension Kit - Bitzer CM-RC-01 Instructions De Montage

4.3 Mounting the "Liquid injection" extension kit

Information
Use an open ring spanner for mounting the in-
jection nozzle to the injection line!
For further information, see Technical Informa-
tion KT-130.
After mounting new components such as discharge gas
temperature sensor, pressure transmitter, injection
nozzle or injection valve:
WARNING
Serious injuries are possible. New component
may suddenly become detached.
Check the thread.
Carefully screw in the new component. Observe
the tightening torques!
Perform a tightness test before commissioning!
After assembly of all components:
NOTICE
!
!
Refrigerant or oil can escape after installation
work on the compressor.
Carry out a leak test before commissioning!
4-cylinder compressors 4JE-13Y .. 4FE-35(Y):
The 4-cylinder compressors are equipped with an in-
jection nozzle:
Before installation, make sure that the injection
nozzle is clean.
▶ Then remove the sealing plug (1/8 NPTF) and
screw the injection nozzle into place (tightening
torque: 10-13 Nm).
▶ Wrap Teflon tape around the conical thread (1/8
NPTF) to seal it.
▶ Screw the injection valve into place. It comes pre-
mounted to the connecting line (including screwed
joints) leading to the injection nozzle.
▶ To avoid undefined vibrations and tensions in the
connecting line, secure the injection valve through
the fixing plate on the cylinder head.
▶ To this end, loosen the corresponding screw on the
cylinder head and tighten it again with the fixing
plate inserted (tightening torque: 80 Nm).
▶ Press the solenoid coil onto the armature until it en-
gages.
▶ Insert the electric connector of the device and screw
it down (tightening torque 5 Nm).

Information
Due to the position of fixing plate and pipe clip
on the cylinder head, the direction of pipe entry
into the valve needs to be considered for in-
stallation.
6-cylinder compressors 6JE-22Y .. 6FE-50(Y):
The 6-cylinder compressors are equipped with two in-
jection nozzles:
Information
Make a brazing joint between liquid line and in-
jection valve before definitely mounting the fix-
ing elements.
Before installation, make sure that the injection
nozzles are clean.
▶ Then remove the sealing plugs (1/8 NPTF) and
screw the injection nozzles into place (tightening
torque: 10-13 Nm).
▶ Wrap Teflon tape around the conical thread (1/8
NPTF) to seal it.
