1.1 Important Information

ATTENTION!
The device is not suitable for operation with a frequency converter.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
ATTENTION!
The heat pump and transport pallet are only joined by the packing film.
ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Ensure that there is a clockwise rotating field: Incorrect phase sequence
causes wrong rotational direction of the ventilator, thus significantly
reducing performance.
ATTENTION!
Never use cleaning agents containing sand, soda, acid or chloride as
these can damage the surfaces.
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!
Before opening the device, ensure that all circuits are isolated from the
power supply.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.

1.2 Legal Regulations and
Directives
The construction and design of the heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be fulfilled. Any further
connection requirements stipulated by local utility companies
must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
This heat pump is operated with the refrigerant R290 (propane).
Please observe the relevant notes on the connection of electrical
cables acc. to Section 3.2 - Switch Box.
1.3 Energy-Efficient Use of the
Heat Pump
With the purchase of this heat pump you are helping to protect
the environment. A prerequisite for energy-efficient operation is
the correct design of the heat source system and heating system
(radiators and circulation pump).
To maintain heat pump efficiency, it is particularly important to
keep the temperature difference between the heating water and
heat source to a minimum. For this reason, it is advisable to de-
sign the heat source and heating system very carefully. A tem-
perature difference of approx. one Kelvin increases the
power consumption by around 2.5%.When designing the
heating system, it should be borne in mind that special consum-
ers such as e.g. DHW preparation should also be taken into con-
sideration and be dimensioned for low temperatures. Underfloor
heating systems (panel heating) are optimally suited for heat
pump use on account of the low flow temperatures (30 °C to
40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation because this increases the tempera-
ture difference, in turn reducing the COP.
