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.
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.
It is a good idea to have a maintenance contract with
a specialist company. The company will conduct the
required maintenance at regular intervals.

to the air duct.
In the bulkhead, underneath the fan, there are 2

tor behind it:

After cleaning fasten the cover and close the side
panel once more.
CLEANING AND RINSING OF UNIT COMPONENTS
CAUTION!
Unit components may be cleaned and
rinsed only by customer service personnel

chemical cleaning agents must be followed
by neutralization of residue and intensive
