28.1 Annual maintenance
► Determine the quality of the heating water by anal
-
ysis. In the event of deviations from the specifica
-
tions, take suitable measures without delay.
It is best to arrange a maintenance agreement with
a heating installation company. The company will
conduct the required maintenance at regular intervals.
NOTE
Any person who works on the refrigerant cir
-
cuit must have a qualification certificate is
-
sued by a body accredited by the industry.
28.2 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 rins-
ing with water. Always observe the techni-
cal data of the manufacturer of the heat ex-
changer.
4. The heat pump system is commissioned by cus

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.
IMPORTANT
Check regularly to ensure that the conden
-
sate 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 ob
-
structions and clean as needed.
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 weather-
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.
Icing of the protective grating
When temperatures fall below freezing and high lev
-
els of humidity are present, ice can form on the pro
-
tective grating of the air flow baffles. In order to ensure
problem-free operations, the ice must be removed on
a regular basis.
