Product Usage Instructions
Safety Information:
Before carrying out any repair work, disconnect the compressor from the electricity network. Turn the main switch off and secure it against unauthorized restart. Ensure there is no voltage, then earth and short-circuit before starting any work.
Disassembly:
Draining the Oil:
Do not dispose of oil in domestic waste. Dispose of the old oil following environmental regulations and national guidelines.
Removing the Air Guide Hood (only for HA):
Disconnecting the Electrical Connections:
Be careful not to damage any cables or components. Damaged parts must be repaired or replaced immediately.
Removing Case Cover:
When removing the case cover, be cautious as residual oil may flow out. Lay absorbent material under the area and dispose of it according to environmental regulations.
Removing the Stator:
Take appropriate measures to secure the stator to prevent falling or crushing. Remove motor cables first, then carefully pull out the stator.
Installation:
Connecting the Stator to the Motor Housing:
Note the direction of the feather key on the stator. Align the parts properly to install them without damaging any cables or components. Position the stator in the engine housing securely.
FAQ:
Q: What should I do if I encounter a heavy weight component during disassembly?
A: Take appropriate precautions to prevent falling or crushing risks. Securely place the heavy component and handle it with care.

Important prerequisites
DANGER
Risk of electric shock
- Before you carry out any repair work, disconnect the compressor from the electricity network.
- Turn the main switch to “O” (OFF) and secure the main switch against an unauthorized restart.
- Before starting any work, ensure that there is no voltage, then earth and short-circuit.
- Cover or cordon off neighboring live parts.
WARNING
The heavy weight of the compressor can be potentially dangerous.
Use all the seals included in the kit.
Disassembly
WARNING
Ensure that the compressor is depressurized before starting work.
Draining the oil
NOTE
Do not dispose of oil in domestic waste.
- Dispose of the old oil in accordance with the environmental regulations and observe national regulations.
Removing the air guide hood (only for HA)
Disconnecting the electrical connections

Damaged parts must be repaired or replaced immediately. - Remove the terminal board and, if available, the PTC terminal board.
- Remove the fan (only for HA).
Removing case cover
WARNING
The heavy weight of the compressor and parts can potentially be dangerous; risk of falling, danger of crushing.
- ATTENTION! The residual oil flows out when the case cover is removed.
Lay an absorbent material under the area and dispose of it in accordance with the environmental regulations.
Removing the stator
WARNING
The heavy weight of the stator can potentially be dangerous; risk of falling, danger of crushing.
- Take appropriate measures to provide a secure location for the stator. Prevent inadvertent rolling.
- Remove the locking screw and the stator screw underneath it.
- Do not damage any cables or components. First remove the motor cables from the compressor housing and then carefully pull out the stator.
Installation
We recommend cleaning the inside of the case before the installation.
There must not be any particles and dirt in the compressor.
To assemble, reverse the order of the steps. Note any particular features such as observance of different torques.
Connecting the stator to the motor housing
WARNING
The heavy weight of the stator can potentially be dangerous; risk of falling, danger of crushing.
- Note the direction of the feather key — stator. You must align the parts in order to install them.
- Do not damage any cables and components. Position the stator in the engine housing as far as it will go.
- Screw in the stator screw. The hardening time of the thread coating is 6 hours. The stator screw must only be used once.
- Screw in the locking screw.
Installing the terminal board and PTC terminal board
- Slightly oil the new seals.
- Connect the electrical connections as per the illustration .
