Maintenance / repair

General
The domestic hot water heat pump is extremely low mainte-
nance. Furthermore, a one-off visual inspection for possible
leaks in the water system and clogging of the condensate drain
must be carried out a few days after commissioning.
The refrigeration circuit of the heat pump does not require
maintenance.
Only use a damp cloth with a little soap solution to clean the do-
mestic hot water heat pump.
ATTENTION!
Disconnect the power supply before opening the device;
possible fan coasting must be considered!
ATTENTION!
Risk of injury caused by sharp-edged fins. Fins must not be
deformed or damaged!
ATTENTION!
The terminal X8 (photovoltaic) can also be energized when the
heat pump is in switched-off state

8.1 Water circuit / condensate drain

The water circuit check is limited to filters that may have been
installed on site and possible leakages. Dirty water filters should
be cleaned and, if necessary, replaced. The seal valve in the end
of the condensate hose must only be checked for contamina-
tion, and cleaned if necessary.

8.2 Filter maintenance

The device does not contain an air filter. Any air filters installed
in the system require regular maintenance to ensure hygienic,
fault-free and efficient system operation. The filter signal acts
as a reminder for the maintenance.
The following maintenance intervals are recommended:
Replace 4 weeks after first startup.

Soiling from building dust, no filter signal.
 Check after 6 months at the latest.
For minor soiling, tap out the filter and clean with a vacuum
cleaner (do not wash!), replace if necessary.
Replace at least once a year.

Dispose of used filters as general household waste.
Reset: Once the maintenance is complete, confirm the mes-
sage and restart the counter for the time interval. Select point
11.4 in the user menu and confirm the 'on' setting with OK. The
display jumps back to 'off'.
NOTE
The filter maintenance work carried out must be logged (see
attachment Operating instructions).

8.3 Cleaning air inlets and outlets

Supply air and exhaust air valves or ventilation grilles and any fil-
ters installed in them must be cleaned regularly.
For information on cleaning and filter change, ask your installer.
NOTE
The setting of the valves must not be changed!
Do not use cleaning agents containing sand, soda, acid or
chloride, as these can damage the surfaces.
8.4 Additional maintenance
measures
Regular maintenance on the ventilation system in a cycle of one
to two years is necessary for hygiene reasons and to ensure
fault-free and energy efficient operation.
The maintenance work includes:
Checking and cleaning the condensate drain

 Checking and cleaning other system components
(e.g. heat exchanger, outside air inlet and extract air outlet)
ATTENTION!
Additional maintenance measures must be carried out by a
qualified technician. It is advisable to sign a maintenance
contract with your installer.
