1.1 Important Information
ATTENTION!
The appliance is not suited for frequency converter operation.
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 intake and discharge openings must not be restricted nor obstructed.
ATTENTION!
Do not use any cleaning agents containing sand, soda, acid or chloride as
these may damage the surface.
ATTENTION!
To prevent the accumulation of deposits (e.g. rust) we recommend using
a suitable corrosion protection system.
ATTENTION!
Prior to opening the unit it must be ensured that all electrical circuits are
disconnected from the power supply.
ATTENTION!
Any work on the heat pump may only be performed by authorized and
qualified after-sales service technicians.
1.2 Legal Provisions and
Guidelines
This heat pump was designed and built in compliance with all re-
levant EU directives, DIN and VDE regulations (see EC 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 observed.
On connecting the heating system, all relevant regulations have
to be complied with.
1.3 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 kee-
ping the temperature difference between the heating water and
the heat source as small as possible. It is therefore strongly re-
commended 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 conside-
ration 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 exchanger is not
contaminated as this would increase the temperature difference
resulting in a lower coefficient of performance.
A considerable contribution to the economical operation is made
by the heat pump controller provided it is set correctly. For more
detailed information refer to the operating manual of the heat
pump controller.
