Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and household cleaning products.
Do not use cleaning or care products that contain abra-
sives, acids and/or chlorine. Such products would de-
stroy the surfaces and could also damage the technical
components of the unit.
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, circulating pumps,
filters, dirt traps) should be inspected as well as cleaned
as needed - at the very least annually - by a qualified
heating or cooling system technician.
The intake and blow-out openings must be inspected for
dirt at regular intervals (depending on the installation lo-
cation) and cleaned, if necessary.
ATTENTION
Check regularly to ensure that the condensate
can drain out of the unit unobstructed. To this
end, regularly check the condensate pan in the
unit and the condensate drain to ensure that
they are clean / free from obstructions and clean
as needed.
Icing of the protective grating
When temperatures fall below freezing and high levels
of humidity are present, ice can form on the protective
grating of the air flow baffles. In order to ensure prob-
lem-free operations, the ice must be removed on a reg-
ular basis.
It is a good idea to have a maintenance contract with a
heating installation company. The company will conduct
the required maintenance at regular intervals.
CLEANING AND RINSING OF UNIT COMPONENTS
CAUTION
Unit components may be cleaned and
rinsed only by customer service personnel
authorized by the manufacturer. Use only
liquids recommended by the manufacturer.
Rinsing of the liquefier with chemical
cleaning agents must be followed by neu-
tralization of residue and intensive rinsing
with water. Always observe the technical
data of the manufacturer of the heat ex-
changer.
Malfunctions
In the event of a malfunction, you can detect the cause of
the malfunction via the diagnostic program of the heating
and heat pump regulator.
Operating manual of the heating and heat pump
regulator.
WARNING
Service and repair work on the compo-
nents of the unit may be performed only
by customer service personnel authorized
by the manufacturer.
Note that no malfunction is displayed if the safety tem-
perature limiter on the electric heating element has
been triggered (depending on unit model).
