12 Maintenance
NOTE
We recommend that you conclude a mainte-
nance agreement with your specialist heating
company.
12.1 Basic principles
The cooling circuit of the heat pump does not require
any regular maintenance.
Local regulations – e.g. EU directive (EC) 517/2014 –
specify tightness checks beforehand and/or for a log
book to be kept for certain heat pumps.
►
Ensure compliance with the local regulations re-
lating to the specific heat pump system.
12.2 Maintenance as required
●
Check and clean the components of the heating
circuit, e.g. valves, diaphragm expansion vessels,
circulation pumps, filters, dirt traps
●
Test the function of the safety valve for the heat-
ing 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 at regular intervals that the condensate
can drain out of the unit freely, without obstruc-
tion. To this end, check the condensate pan in the
unit and the evaporator regularly for dirt/clogging
and clean as necessary
Check the evaporator and the condensate
pan and clean them, if required
