12 Maintenance
NOTE
We recommend that you conclude a
maintenance agreement with an accredited
heating company.
12.1 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 leak checks beforehand
and/or for a logbook to be kept for certain heat pumps.
►
Ensure compliance with local regulations with
regard to the specific heat pump system.
12.2 Maintenance as required
●
Checking and cleaning the components of the
heating circuit, e.g. valves, expansion vessels,
recirculating pumps, filters, dirt traps
●
Test the function of the safety valve for the heating
circuit
●
Always regularly control for unimpeded air in-
feed accordingly. Constrictions or even blockages
which, for example occur
●
when applying house insulation with polysty-
rene balls
● through packaging material (foils, films, car
-
tons etc.)
●
through foliage, snow, icing or similar weath-
er-related deposits
●
through vegetation (bushes, tall grass etc.)
● through air shaft covers (fly protection screens
etc.)
and which must be prevented and/or removed im-
mediately
●
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
