12 Maintenance
NOTE
We recommend that you conclude a
maintenance agreement with an accredited
heating company.
12.1 Basic principles
The refrigerant circuit of the heat pump requires no
regular maintenance.
Local regulations– e.g. EU Regulation (EC) 517/2014 –
include a requirement for 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.
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
