16 Maintenance
NOTE
We recommend that you sign a maintenance
agreement with an accredited heating
company.
16.1 Basic principles
The cooling circuit of the heat pump requires no
regular maintenance.
Local regulations– e.g. EU Regulation (EC) 517/2014
– among other things, require leakage controls
beforehand and/or for a log book to be kept for certain
heat pumps.
►
Ensure compliance with local regulations with
regard to the specific heat pump system.
16.2 Maintenance as required
Yearly, more frequently if necessary:
●
Checking and cleaning the components of the
heating circuit, e.g. valves, expansion vessels,
circulation pumps, filters, dirt traps.
●
Test the function of the safety valve for the heating
circuit.
●
Check regularly to ensure that the condensate
can drain out of the unit freely, without obstruction.
To this end, check the condensate pan in the unit
and the evaporator regularly for dirt / blockages
and clean as necessary.
16.3 Yearly maintenance
►
Record the quality of the heating water analytically.
In case of deviations from the specifications, take
suitable measures without delay.
16.4 Check evaporator and
condensate pan and clean if
required
Yearly, more frequently if necessary:
●
Take off the front façade and the cover. This
allows access to the cleaning opening (1) and the
area below this between the evaporators.

the manufacturer's instructions.
► After flushing the condenser with chemical
cleaning product: Neutralise any residues and
