1.1 Important Information

ATTENTION!
The unit is not suited for operation with a frequency converter.
ATTENTION!
During transport, the heat pump must not be tilted more than 45° (in
either direction).
ATTENTION!
The heat pump and transport pallet are only connected by the packaging
film.
ATTENTION!
The air intake and discharge openings must not be restricted nor
obstructed.
ATTENTION!
Clockwise phase sequence must be ensured: Operating the compressor
in the wrong sense of rotation, may result in damage to the compressor.
An incorrect phase sequence causes the fan to operate in the wrong
sense of rotation leading to a significant reduction in performance.
ATTENTION!
Do not use any cleaning agents containing sand, soda, acid or chloride as
these may damage the surface.
ATTENTION!
To prevent the formation of deposits (e.g. rust) in the plate heat
exchanger of the heat pump, we recommend using an appropriate
corrosion protection system
ATTENTION!
To prevent consequential damage it is imperative that the water circuit be
neutralized after cleaning using appropriate agents.
ATTENTION!
Prior to opening the unit it must be ensured that all electrical circuits are
disconnected from the power supply.
ATTENTION!
Work on the heat pump may be done only by an authorized and qualified
customer service.

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 includes the user's abiding by the manufacturer's
product brochures. Please refrain from tampering with or altering
the device.
1.3 Legal Provisions and
Guidelines
This heat pump was designed and built in compliance with all rel-
evant EU directives, DIN and VDE regulations (see CE Declara-
tion of Conformity).
The electrical connection of the heat pump must be performed
according to and conforming with all relevant VDE, EN and IEC
standards. Beyond that, all technical connection requirements of
the local electrical utility company have to be adhered to.
On connecting the heating system, all relevant regulations have
to be heeded.
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.
The refrigerant circuit of this heat pump is hermetically sealed. It
contains the Kyoto protocol approved refrigerant R417A with a
GWP value of 1950. It is CFC-free, does not deplete ozone and
is non-flammable.
1.4 Energy-Efficient Use of the
Heat Pump
By purchasing this heat pump you contribute to the protection of
the environment. A prerequisite for energy-efficient operation is
the proper design of the heat source system and the heat utiliza-
tion system.
One of the most important factors of heat pump efficiency is
keeping the temperature difference between the heating water
and the heat source as small as possible. It is therefore strongly
recommended that the design of both the heat source system
and the heat distribution system be carried out with great care. A
1 Kelvin (1 °C) higher temperature difference corresponds
to an increase in power consumption of approx. 2.5%. When
designing the heating system care must be taken that special ap-
plications such as domestic water heating are taken into consid-
eration and dimensioned for low temperature operation. Heat
pumps are optimally suited for underfloor heating (surface/ra-
diant heating) applications due to the low supply temperatures
(30 °C to 40 °C).
During operation it is essential that the heat exchangers are not
contaminated as this would increase the temperature difference
resulting in a lower coefficient of performance.
