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 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, 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.
