Care of the unit
The outer surfacesof theunit can be cleaned with a damp
cloth and household cleaning products.
do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy 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 regular,
technically-qualified maintenance.
According to EU regulation (Ec) 842/2006 of may 17,
2006, leak inspections and maintenance of a log book
are required for certain heat pumps!
The criteria for conducting leak inspections and
maintaining a log book are based on the hermetic
impermeability of the cooling circuit and the refrigerant
capacity of the heat pump! No log book is required for
heat pumps with a refrigerant capacity of < 3kg. With all
other heat pumps, the log book is included with all other
delivered materials.
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, fil-
ters, dirt traps) should be inspected as well as cleaned as
needed – at the very least annually – by a qualified heat-
ing 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
Regularly check to ensure that the condensate
can drain out of the unit unobstructed. To this
end, check the condensate pan in the unit as well
as the condensate drain on a regular basis to en-
sure that they are clean / free from obstructions;
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
problem-free operations, the ice must be removed on a
regular 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 Flushing unit Components
WarnIng!
Unit components may be cleaned and
flushed only by customer service person‑
nel authorised by the manufacturer. Use
only liquids recommended by the manu‑
facturer.
Flushing of the condenser with chemical
cleaning agents must be followed by
neutralisation of residue and intensive
flushing with water. always observe the
technical data of the manufacturer of the
heat exchanger.
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.
