1.1 Important Information
ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
ATTENTION!
If the heat pump or circulating pumps are controlled externally, an flow
rate switch is required to prevent the compressor from being switched on
when there is no volume flow.
ATTENTION!
The heat pump must not be tilted more than max. 45° (in either direction).
ATTENTION!
The transport securing devices must be removed prior to commissioning.
ATTENTION!
The heating system must be flushed prior to connecting the heat pump.
ATTENTION!
With fully demineralized water, it is important to ensure that the minimum
permissible pH value of 7.5 (minimum permissible value for copper) is
complied with. Failure to comply with this value can result in the heat
pump being destroyed.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat
pump in order to protect the evaporator against the ingress of impurities.
ATTENTION!
The brine solution must contain at least 25 % of an antifreeze agent on a
mono-ethylene glycol or propylene glycol basis and must be mixed prior
to filling.
ATTENTION!
Ensure the rotary field is clockwise when connecting the mains cables (if
the rotary field is not clockwise, the heat pump will not work properly, is
very loud and may cause damage to the compressor).
ATTENTION!
It is not permitted to connect more than one electronically regulated
circulating pump via a relay output.
ATTENTION!
Start-up must be performed in accordance with the installation and
operating instructions of the heat pump manager..
ATTENTION!
To prevent the accumulation of deposits (e.g. rust) we recommend using
a suitable corrosion protection system.
ATTENTION!
Disconnect all electrical circuits from the power supply before opening
the enclosure.

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 relevant project
planning documents. Please refrain from tampering with or alter-
ing the device.
1.3 Legal Provisions and
Guidelines
This heat pump is designed for use in a domestic environment
according to Article 1, Paragraph 2 k) of EC directive 2006/42/EC
(machinery directive) and is thus subject to the requirements of
EU directive 2014/35/EU (low-voltage directive). It is thus also in-
tended for use by non-professionals for heating shops, offices
and other similar working environments, in agricultural establish-
ments and in hotels, guest houses and similar / other residential
buildings.
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. For details refer to the EC Declaration of Con-
formity in the appendix.
The electrical connection of the heat pump must be performed
according to and conforming with all relevant VDE, EN and IEC
standards. Beyond that, the connection requirements of the local
utility companies have to be observed.
The heat pump is to be connected to the heat source and heat
distribution systems in accord-ance with all applicable provi-
sions.
This unit can be used by children aged 8 and over and by per-
sons with limited physical, sensory or mental aptitude or lack of
experience and/or knowledge, providing they are supervised or
have been instructed in the safe use of the unit and understand
the associated potential dangers.
Children must not play with the device. Cleaning and user main-
tenance must not be carried out by children without supervision.
ATTENTION!
Any work on the heat pump may only be performed by an authorised and
qualified customer service.
ATTENTION!
When operating or maintaining a heat pump, the legal requirements of the
country where the heat pump is operated apply. Depending on the
refrigerant quantity, the heat pump must be inspected for leaks at regular
intervals by a certified technician, and these inspections must be
recorded.
More information can be found in the accompanying log book.
1.4 Energy-Efficient Use of the
Heat Pump
By operating this heat pump you contribute to the protection of
our environment. A prerequisite for an efficient operation is the
proper design and sizing of the heating system and the heat
source system. In particular, it is important to keep water flow
temperatures as low as possible. All energy consumers con-
nected should therefore be suitable for low flow temperatures. A
1 K higher heating water temperature corresponds to an increase
in power consumption of approx. 2.5 %. Low-temperature heat-
ing systems with flow temperatures between 30 °C and 50 °C
are optimally suited for energy-efficient operation.
