Safety notes
1.1 Symbols and markings
Particularly important information in these instructions is
marked with CAUTION! and NOTE.
CAUTION!
Immediate danger to life or danger of severe personal injury or
significant damage to property.
NOTE
Risk of damage to property or minor personal injury or
important information with no further risk of personal injury
or damage to property.
1.2 Intended use
This device is only intended for use as specified by the manu-
facturer. The air-to-water heat pump is to be used exclusively
for the heating and cooling of heating water. It can be used in
new or existing heating systems.
The heat pump is designed exclusively for outdoor installation.
The instructions in the chapter "Installation" must be observed.
Any other use beyond that intended by the manufacturer is
prohibited. This requires the user to abide by the relevant pro-
ject planning documents. Please refrain from tampering with or
altering the device.
1.3 Life cycle
The device is designed for a service life of 15 years. Mainte-
nance must be carried out as per the maintenance instructions.
Before the end of the intended service life and taking into ac-
count the current technical rules, the operator must carry out
an assessment regarding continued operation. Based on the
assessment, the operator must make a decision regarding con-
tinued operation, decommissioning or measures to be carried
out. If the assessment and any measures to be carried out are
not implemented before the end of the intended service life,
the device must be decommissioned.
1.4 Legal regulations and directives
The construction and design of the heat pump complies with all
relevant EU directives, EN/DIN/VDE regulations (see CE decla-
ration of conformity).
When connecting the heat pump to the power supply, the rele-
vant VDE, EN and IEC standards are to be adhered to. Any fur-
ther connection requirements stipulated by local utility compa-
nies must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
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.

CAUTION!
Work on the heat pump must only be performed by
authorised and qualified after-sales service technicians!
CAUTION!
When operating or maintaining a heat pump, the legal
requirements of the country where the heat pump is operated
apply. Depending on the refrigerant fill quantity, the heat
pump must be inspected for leaks at regular intervals by a
certified technician, and these inspections must be recorded.
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.
