Maintenance
In case of renovation (exchange installation) and a previously dirty
system, more frequent cleaning/service may be necessary in the first
weeks after installation.
Display activated alarm
▶ Check the alarm log (instructions for the control device).
Function test
▶ Carry out function check ( Chap. 7.7).
Check the magnetite indicator
After installation and startup the magnetite indicator must be checked at
more frequent intervals. If a lot of magnetic dirt is clinging to the
magnetic bar in the particulate filter and that dirt frequently causes an
alarm related to the poor flow (e.g., low or poor flow, high flow supply or
HP alarm) a magnetite filter must be installed to avoid regular draining of
the indicator. A filter also increases the longevity of components in the
heat pump as well as the remaining parts of the heating system.
8.1
Particle filter
WARNING
Strong magnet!
Can be harmful to pacemaker wearers.
▶ Do not clean the filter or check the magnetite indicator if you are a
pacemaker wearer.
The filter prevents particles and contamination from entering the heat
pump. Over time, the filter may become blocked and must be cleaned.
The system does not need to be emptied to clean the filter. The filter is
integrated into the shut-off valve.
Cleaning the strainer
▶ Close the valve (1).
▶ Unscrew the cap (manually) (2).
▶ Take out the strainer and clean it with running water over it or by
pressure cleaning.
▶ Check attached debris on the cap's magnet (3) and clean it.
▶ Reinstall the strainer (4). For proper assembly, make sure that the
guide bumps fit into the recesses in the valve.
▶ Screw the cap back on (hand tight).
▶ Open the valve (5).

Check and clean the magnetite filter
Check and clean the magnetite filter 1-2 times a year, but directly after
installation and commissioning the filter should be checked and cleaned
more frequently. See the instruction that is supplied with the filter for
correct procedure.
8.2
Service of expansion vessel
NOTICE
Material damage due to negative pressure!
Negative pressure can occur during drainage of the appliance.
▶ In case the outdoor unit is placed above the indoor unit: vent the
outdoor unit during drainage, if the pipework between outdoor unit
and indoor unit does not allow negative pressure.
▶ Close the valves SC1 and VC3 to the heating system prior to drainage
or vent the heating system during drainage.
Regular service of the expansion vessel is important to avoid air in the
heating system.
1. Close valves to the heating system, SC1 and VC3, as well as valve VC4
between indoor unit and outdoor unit.
2. Close automatic air vent valves that are connected to the indoor unit.
3. Connect a drainage hose to the manual air vent valve at PC0.
4. Open the manual air vent valve and let the water drain until no more
water comes out of the appliance.
5. Keep manual air vent valve at PC0 open.
