INSTALLATION
MAINTENANCE AND CLEANING
13. Maintenance and cleaning
If heat meters are installed, clean their strainers frequently as
they block easily.
When the heat pump operation is impaired (high pressure lim-
iter trips) through deposits of corrosion by-products (rust sludge)
inside the condenser, only dissolving them by means of solvents
used by our service department will remove this problem.
14. Troubleshooting
Note
Please observe the heat pump manager operating and
installation instructions.
Note
The following inspection instructions may only be carried
out by a qualified contractor.
If you cannot locate the fault using the heat pump manager, use
the controls on the IWS.

the instructions.
14.1 IWS controls
