Dealing with malfunctions
FIGHTER 410P
For the Installer
26
■ Shut down FIGHTER 410P by turning the switch
(8) to “0”.
■ Remove the lower front cover.
■ Loosen the venting screw with a screwdriver. Hold
a cloth around the screwdriver blade as a certain
amount of water may run out.
■ Insert a screwdriver and turn the pump rotor.
■ Screw in the venting screw.
■ Start FIGHTER 410P and check whether the circu-
lation pump runs.
It is usually easier to start the circulation pump with
FIGHTER 410P running, switch (8) set to “1”. If help-
ing the circulation pump to start is performed with
FIGHTER 410P running, be prepared for the screw-
driver to jerk when the pump starts.
Help starting the circulation
pump
If the extract air temperature (read on channel 5) is
only insignificantly lower than the room temperature at
the same time as the compressor is operational, this
indicates a probable fault in the refrigerant circuit or its
controller. Request a service.
When the compressor is not operational the extract air
temperature lies at about the same level as the room
temperature.
High extract air temperature
Should abnormal noise come from the fan, this may
need cleaning. Contact your installer.

The pressostats are located behind the middle service
cover. To reset a tripped pressure switch, press the but-
ton on the top of it; see diagram.
The pressostat may only be reset under the supervi-
sion of a qualified installer.
When the cause of the fault has been put right, the
fault code must be cleared from the display by switch-
ing the heat pump off and on again.
