1.3 Intended use

This device is only intended for use (see chap. 2) as specified by
the manufacturer. Any other use beyond that intended by the
manufacturer is prohibited. This requires the user to abide by
the relevant project planning documents. Please refrain from
modifying or altering the device.

1.4 Legal regulations and directives

The construction and design of the heat pump comply with all
valid EU directives, DIN and VDE regulations (see CE Declara-
tion of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards must be complied with. Any
further connection requirements stipulated by local utility com-
panies must also be observed.
When connecting the heating system, the applicable regula-
tions must be complied with.
The device is filled with flammable refrigerant R290 (propane)
and is only intended for outdoor installation. Suitable safety
measures must be implemented for installation, assembly, op-
eration and disposal.
Work on the heat pump must only be carried out by people with
the following knowledge. Use by people who have not been in-
structed is not permissible.

1.5 Energy-efficient use of the heat
pump
By operating this heat pump, you are helping to protect the en-
vironment. A prerequisite for energy-efficient operation is the
correct design of the heat source system and heating system.
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
design the heat source and heating system very carefully. A
temperature difference that is higher by 1 Kelvin (1°C) in-
creases the power consumption by around 2.5%. When de-
signing the heating system, it should be borne in mind that spe-
cial consumers such as domestic hot water preparation should
also be taken into consideration and dimensioned for low tem-
peratures. 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, as this increases the temperature
difference, which in turn reduces the coefficient of perfor-
mance (COP).
When set correctly, the heat pump manager is also an essential
factor in the energy-efficient use of the heat pump. Further in-
formation can be found in the heat pump manager operating
instructions.
