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
notified of the operation of the heat pump system.
The system is air-free.
Installation check using the rough checklist has
been completed successfully.
1.
Ensure that the following points are fulfilled com
-
pletely:
● Clockwise rotating field 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
●
The power supply for the heat pump is equipped
with an all-pole circuit-breaker with at least 3 mm
contact spacing (IEC 60947-2)
●
The tripping current is complied with
● The heating circuit has been flushed and vented
● All shut-off devices of the heating circuit are open
●
The pipe systems and components of the system
are tight
2.
Carefully fill in and sign the notice of completion
for the heat pump systems.
3. In Germany: Send the notice of completion

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, on and under the unit which do not flow
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.
Local regulations– e.g. EU Regulation (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
regard to the specific heat pump system.
12.2 Maintenance as required
●
Check and clean the components of the heating
circuit, e.g. valves, diaphragm expansion vessels,
circulation pumps, filters, dirt traps
●
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, films, car
-
tons etc.)
●
through foliage, snow, icing or similar weath-
er-related deposits
● through vegetation (bushes, tall grass etc.)
● through air shaft covers (fly protection screens
etc.)
and which must be prevented and/or removed im-
mediately
