By checking the installation you prevent damage
to the heat pump system, which could be caused
by work carried out improperly.
Check that
● clockwise rotary field of the load power sup-
ply (compressor) is ensured
● The heat pump installation and assembly
have been carried out according to the require-
ments of this operating manual
● the electrical installation work has been com-
pleted properly
● The power supply for the heat pump must
be equipped with an all-pole automatic cir-
cuit-breaker with at least 3 mm contact spacing
to IEC 60947-2
● The heating circuit is flushed, filled and thor-
oughly vented
● All valves and shut-off devices of the heating
circuit are open
● All pipe systems and components of the system
are leaktight

29 Maintenance of the unit
The cooling circuit of the heat pump requires no regu-
lar maintenance.
According to EU regulation (EC) 517/2014, leak
inspections and maintenance of a log book are
required by law for certain heat pumps!

Log book for heat pumps, Section “Information on
use of the log book”
The components of the heating circuit and the heat
source (valves, expansion vessels, circulation pumps,
filters, dirt traps) should be checked and cleaned as
necessary, but at least by qualified personnel (heating
or cooling system fitters).
Always regularly control for unimpeded air infeed ac-
cordingly. 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 imme-
diately.
IMPORTANT
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
condensate drain regularly for dirt / blockages
and clean as necessary.
