commissioned by after-sales service authorised
by the manufacturer; this is a chargeable service.
13 Maintenance
NOTE
We recommend that you sign a maintenance
agreement with an accredited heating
company.
13.1 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.
13.2 Maintenance as required
●
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
●
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
Check the evaporator and the condensate
pan and clean them, if required
1. Remove the front panel, the side panels and the
cover, thus gaining access to the cover of the
cleaning opening (1).
2. After the cover is removed (1), the entire conden-
sate pan area before (2) and after (3) the evapo-
rator is visible and can be cleaned if necessary.

As an alternative, the lateral air ducts, the side walls,
the louvre grilles and blind covers can be removed (if
necessery also the fan module) , to obtain better ac-
cess.
