1.1 Important Information

ATTENTION!
The heat pump is not secured to the wooden pallet.
ATTENTION!
The heat pump must not be tilted more than 45° (in any direction).
ATTENTION!
Do not use the holes in the panel assemblies for lifting the device!
ATTENTION!
In the case of large-volume heating circuits, an additional expansion
vessel must be used to supplement the installed expansion vessel
(24 litres, 1.0 bar admission pressure).
ATTENTION!
The brine solution must contain at least a 25 % concentration of a
monoethylene glycol or propylene glycol-based antifreeze, which must
be mixed before filling.
ATTENTION!
Observe the clockwise rotating field when connecting the electrical
mains cable (if rotating field is not clockwise, the heat pump will not work
properly and will be very noisy).
ATTENTION!
The heat pump must be started up in accordance with the installation and
operating instructions of the heat pump controller.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet of the heat
pump to protect the evaporator against the ingress of impurities.
ATTENTION!
We recommend the installation of a suitable corrosion protection system
to prevent the formation of deposits (e.g. rust) in the condenser of the
heat pump.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
Disconnect all electrical circuits from the power source prior to opening
the device.

1.2 Intended Use

This device is only intended for use as specified by the manufac-
turer. Any other use beyond that intended by the manufacturer is
prohibited. This requires the user to abide by the manufacturers
product information. Please refrain from tampering with or alter-
ing the device.
1.3 Legal Regulations and
Directives
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. Refer to the EC Declaration of Conformity in
the appendix for details.
The heat pump must be connected to the power supply in com-
pliance with all relevant VDE, EN and IEC standards. Any further
connection requirements stipulated by local utility companies
must also be observed.
The heat pump is to be connected to the heat source system and
the heating system in accordance with all applicable regulations.
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or their inexperience or lack of knowledge, must not operate this
device without supervision or instruction by the person in charge.
Children must be supervised to ensure that they do not play with
the device.
1.4 Energy-Efficient Use of the
Heat Pump
By operating this heat pump you are helping to protect our envi-
ronment. Both the heating system and the heat source must be
properly designed and dimensioned to ensure efficient operation.
It is particularly important to keep water flow temperatures as low
as possible. All connected energy consumers should therefore
be suitable for low flow temperatures. Raising the heating water
temperature by 1 K corresponds to an increase in energy con-
sumption of approx. 2.5 %. Low-temperature heating systems
with flow temperatures between 30 °C and 50 °C are particularly
well-suited for energy-efficient operation.
