MAINTENANCE
DANGER: Risk of electric shock!
▶ Switch off the main power supply before starting work
on the electrical part.
We recommend that a function check be performed regularly by a
competent person.
▶ Only use genuine spare parts!
▶ Refer to the spare parts list when ordering spare parts.
▶ Always renew seals and O-rings removed during servicing or repair
work.
During service, the activities described below should be conducted.
Show alarms
▶ Check the alarm log ( Chapter 21.11).
FUNCTION CHECK
▶ A function check should be performed in connection with each service
( Page 36).
ELECTRICAL CABLE ROUTING
▶ Check the electrical cable routing with regard to mechanical damage
and replace defective cables.
CHECK THE PARTICLE FILTERS FOR THE HEATING SYSTEM AND
COLLECTOR SYSTEM
The filters prevent dirt from entering the heat pump. If they are clogged,
they can cause malfunctions.
It is not necessary to empty the installation in order to
clean the filters. Filter and shut-off valve are integrated.
▶ Turn off the heat pump.
▶ Close the valve.
▶ Loosen the lid.
▶ Remove the circlip with the circlip pliers.
▶ Pull the filter out and clean it, if necessary, under running water.
