11 Commissioning
CAUTION
Prior to commissioning the unit, the facing
panels must be closed and the fan protec-
tion grille must be mounted.
The relevant planning and design data of the system
is documented in full.
The relevant energy supply company has been
notiedoftheoperationoftheheatpumpsystem.
The system is air-free.
Installation check using the rough checklist has
been completed successfully.
1. Ensurethatthefollowingpointsarefullledcom-
pletely:
● Clockwise rotating eld is present for the load
supply at the compressor (for 400 V connection
only)
● The system is installed and mounted according to
this operation manual
● The electrical installation has been carried out
properly according to this operation manual and
the local regulations

with an all-pole circuit-breaker with at least 3 mm
contactspacing(IEC60947-2)
● The tripping current is complied with
● Theheatingcircuithasbeenushedandvented
● Allshut-odevicesoftheheatingcircuitareopen
● The pipe systems and components of the system
are tight

12 Maintenance
NOTE
We recommend that you conclude a mainte-
nance agreement with your specialist heat-
ing company.
NOTE
Water accumulations resulting from extreme
weather conditions, or from condensation
in, onandunder the unitwhich do not ow
away via the condensate discharge are nor-
mal and do not constitute a heat-pump mal-
function or defect.
12.1 Basic principles
The cooling circuit of the heat pump does not require
any regular maintenance.
Localregulations–e.g.EURegulation(EC)517/2014–
among other things, require leak checks beforehand
and/or for a logbook to be kept for certain heat pumps.
► Ensure compliance with local regulations with
regardtothespecicheatpumpsystem.
12.2 Maintenance as required
● Check and clean the components of the heating
circuit, e.g. valves, diaphragm expansion vessels,
circulationpumps,lters,dirttraps
● Test the function of the safety valve for the heat-
ing circuit
● Always regularly control for unimpeded air in-
feed accordingly. Constrictions or even blockages
which, for example occur
● when applying house insulation with polysty-
rene balls
● through packaging material (foils, lms, car-
tons etc.)
● through foliage, snow, icing or similar weath-
er-related deposits
● throughvegetation(bushes,tallgrassetc.)
● throughairshaftcovers(yprotectionscreens
etc.)
and which must be prevented and/or removed im-
