If necessary, move the lever above the compart-
ment of the heat pump module completely
upwards. Now insert the heat pump module into
the compartment.

Push the heat pump module into the frame with
both hands as far as it will go. During the process,
the rear couplers interlock. In addition, a lever
mechanism is triggered which ensures that the
lever, which was previously positioned upwards, is
guided downwards again.

The end position of the module is reached as soon
as the lever engages downwards in its target posi-
tion and completely encloses the lateral nipples.
The lever thus combines three important functions:
On the one hand, it secures the position of the
cooling module for safety and prevents uninten-
tional loosening of the hydraulic couplers due to
existing hydraulic pressure during operation. In
addition, the correct position of the module is dis-
played: The couplers covered by the module are
now connected to each other ready for operation.
The third function provides you with the option of
conveniently disconnecting the module from the
system again in the event of service/maintenance.

The MWL has now reached the status as shown in

Release the lift panel from its latch and pull it com-
pletely out of the unit until it is in the lower end
position. Make sure that the lift panel has been
fully lowered before placing the ventilation module.
This way it avoids possible damage to the ventila-
tion module and the roof connections.
