1.1 Important Information
The heat pump is not attached to the
wooden pallet.
The heat pump must not be tilted
more than max. 45° (in either direction).
Do not lift unit by the holes in the
panel assemblies!
Flush the heating system prior to
connecting the heat pump.
The supplied strainer is to be fitted
in the heat source inlet of the heat pump in order
to protect the evaporator against contamina-
tion.
The brine must contain at least 25 %
of a frost and corrosion protection agent on a
monoethylene glycol or propylene glycol basis.
The clockwise phase sequence
must be observed when connecting the load
line.
Commissioning of the heat pump
must be performed in accordance with the
mounting and operating manual of the heat
pump controller.

1.2 Legal Provisions and Directives
This heat pump conforms to all relevant DIN/VDE
regulations and EU directives. For details refer to
the EC Declaration of Conformity in the appendix.
The electrical connection of the heat pump must be
performed according to and conforming with all re-
levant VDE, EN and IEC standards. Beyond that, the
connection requirements of the local utility compa-
nies have to be observed.
The heat pump is to be connected to the heat source
and heat distribution systems in accordance with all
applicable provisions.
1.3 Energy-Efficient Use of the Heat
Pump
By operating this heat pump you contribute to the
protection of our environment. A prerequisite for an
efficient operation is the proper design and sizing of
the heating system and the heat source system. In
particular, it is important to keep water flow
temperatures as low as possible. All energy
consumers connected should therefore be suitable
for low flow temperatures. A 1 K higher heating water
temperature corresponds to an increase in power
consumption of approx. 2.5 %. Underfloor heating
systems with flow temperatures between 30 °C and
40 °C are optimally suited for energy-efficient
operation.
