1.1 Important Information
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
ATTENTION!
The heat pump must not be tilted more than max. 45° (in either direction).
ATTENTION!
The transport securing devices must be removed prior to commissioning.
ATTENTION!
The heating system must be flushed prior to connecting the heat pump.
ATTENTION!
The supplied strainer must be fitted in the heating water inlet of the heat
pump in order to protect the condenser against the ingress of impurities.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat
pump in order to protect the evaporator against the ingress of impurities.
ATTENTION!
The brine solution must contain at least 25 % of an antifreeze agent on a
mono-ethylene glycol or propylene glycol basis and must be mixed prior
to filling.
ATTENTION!
The clockwise phase sequence must be observed when connecting the
load lines (the heat pump will deliver no output and will be very noisy
when the phase sequence is incorrect).
ATTENTION!
Commissioning is to be effected in accordance with the installation and
operating manual of the heat pump controller.
ATTENTION!
To prevent the accumulation of deposits (e.g. rust) we recommend using
a suitable corrosion protection system.
ATTENTION!
Disconnect all electrical circuits from the power supply before opening
the enclosure.
1.2 Legal Provisions and
Guidelines
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. For details refer to the EC Declaration of Con-
formity in the appendix.
The electrical connection of the heat pump must be performed
according to and conforming with all relevant VDE, EN and IEC
standards. Beyond that, the connection requirements of the local
utility companies have to be observed.
The heat pump is to be connected to the heat source system and
the heating or cooling system in accordance with all applicable
regulations.
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
1.3 Energy-Efficient Use of the
Heat Pump
By operating this heat pump you contribute to the protection of
our environment. The heating or cooling system and the heat
source must be properly designed and dimensioned to ensure ef-
ficient operation. In particular, it is important to keep water flow
temperatures as low as possible. All energy consumers con-
nected 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 %. Low-temperature heat-
ing systems with flow temperatures between 30 °C and 50 °C are
optimally suited for energy-efficient operation.
