1.1 Important Information
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
The device is not suitable for operation with a frequency converter.
ATTENTION!
Never install the device in rooms in which there are any permanent
ignition sources.
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: Operating the compressor
in the wrong rotational direction could cause damage to the compressor.
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!
The refrigerating circuit may not be damaged in any way.
ATTENTION!
Before opening the device, ensure that all circuits are isolated from the
power supply.
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).
The relevant VDE, EN and IEC standards must be adhered to
when connecting the heat pump to the power supply or carrying
out maintenance work. Any further connection requirements stip-
ulated by local utility companies must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
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.
1.3 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).
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and heat
source as small as possible. 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. domestic hot water preparation should also be
taken into consideration and 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.
Correct adjustment of the heat pump controller is also important
for energy-efficient use of the heat pump. Further information can
be found in the heat pump controller’s operating instructions.
