f If you have selected a lower fuse protection for the compres-
sor, you will need to limit the maximum power consumption.
In the COMMISSIONING/ COMPRESSOR menu, adjust the-
MAXIMUM CURRENT parameter. Observe the information in
the commissioning instructions for the heat pump manager.
The cable cross-section must correspond to the appliance’s maxi-
mum possible operating current (see “Specification/Data tables”).

9. Installation
9.1 Transport
f Transport the appliance in its packaging to protect it against
damage.
f Protect the appliance against heavy impact during transport.
- If the appliance needs to be tilted during transport, this must
only be for a short time and it must only be tilted on one of
its longitudinal sides.
The longer the appliance is tilted, the greater the distribution
of refrigerant oil inside the system.
- Storage and transport at temperatures below -20°C and
above +50°C are not permissible.
9.2 Siting
f Remove the packaging film and the top and side EPS pad-
ding.
f Tilt the appliance forwards slightly.
f Place wooden blocks underneath the back of the appliance.
f Tilt the appliance backwards slightly and lift the appliance off
the pallet. To do this, use the handles provided at the back
and the front adjustable rubber feet at the bottom.
f Position the appliance on the prepared substrate.
f Observe minimum distances (see chapter "Preparations/
Minimum clearances").
f Level the appliance horizontally by adjusting the feet.
9.3 Installing the heat source system
!
Material losses
The maximum heat source application limit of 40°C must
not be maintained for more than 30minutes. Continu-
ous operation with a heat source temperature above the
maximum application limit (see chapter "Specification/
Data table") is not permitted.
Note
Engineer the heat source system for the appliance ac-
cording to the technical guides.
Note
The appliance can also be operated using groundwater
as a heat source. An intermediate circuit is required for
operation using groundwater.
f Fit the GWS groundwater module or a heat exchang-
er.
f Fill the intermediate circuit with an ethylene glycol/
water mixture with at least 25% by vol. ethylene
glycol. Check for leaks.
f In the heat pump manager, set the source medium
to "WATER". The minimum return source tempera-
ture is set automatically to +2°C.
Permitted brine:
Part number
MEG 10 Heat transfer medium as concentrate on
an ethylene glycol base

9.3.1 Circulation pump and required flow rate
The flow rate is automatically controlled by the heat pump man-
ager. The circulation pump cannot be set manually.
