3.8 Mounting the discharge gas temperature
sensor
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!
▶ Remove the sealing plug from the connector on the
cylinder head marked by a circle and clean the
threaded bore.
▶ Then screw the discharge gas temperature sensor
in (tightening torque 35-40 Nm) and tighten the con-
nector by hand.
3.9 Mounting the oil monitoring
Information
A prerequisite for mounting the oil monitoring is
a bearing cover with the respective connection
(M20x1.5).
Information
For further details, see Technical Information
KT-180.
Information
Delivery in a pre-setup state:
If the prism unit of the oil monitoring has been
ordered pre-assembled, the compressor will
have already been tested as a whole in the fact-
ory for pressure strength and tightness. In this
case, it will only be necessary to screw on the
opto-electronic unit and to connect it electrically.
Subsequent tightness testing will not be re-
quired in this case.

If subsequently mounting the prism unit of the oil monit-
oring:
NOTICE
!
!
Risk of refrigerant loss!
Check the thread.
Carefully screw the new component in and
tighten it to the prescribed tightening torque.
Perform a tightness test before commissioning!
Mounting the prism unit
Preferably mount the enclosed prism unit, before the
compressor is mounted to the system.
Tilt the compressor by lifting it up at the bottom of
the bearing cover in order that the oil in the oil
pocket of the bearing cover cannot drain through the
connecting bore.
Screw the screw (M20x1,5) onto the bearing cover
and thoroughly clean the threaded bore.
Check the inside and outside of the glass cone of the
prism unit for cleanliness and clean, if required.
▶ Screw the prism unit with metal gasket into the bear-
ing cover. Tightening torque 75 Nm.
▶ Perform a tightness test:
DANGER
Risk of bursting due to excessive pressure!
The pressure applied during the test must never
exceed the maximum permitted values!
Test pressure: 1.1-fold of the maximum allow-
able pressure (see name plate). Make a distinc-
tion between the high-pressure and low-pres-
sure sides!
Mounting the opto-electronic unit
NOTICE
!
!
Risk of compressor failure!
Possible failure of the protection device due to
penetrating moisture!
Ensure that the cable connection always faces
down!
▶ Carefully insert the opto-electronic unit into the
prism unit up to the stop.
▶ Tighten the union nut of the opto-electronic unit by
hand.
