1.1 Important information

ATTENTION!

For devices with a refrigerant quantity of 6 kg or more, the refrigerating
circuit must be checked for leaks each year in compliance with regulation
(EC) No. 842/2006.

ATTENTION!

The device is not suitable for operation with a frequency converter.

ATTENTION!

When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).

ATTENTION!

Before start-up, the transport fastening must be removed.

ATTENTION!

Do not restrict or block the area around the air intake or outlet.

ATTENTION!

Observe country-specific building regulations!

ATTENTION!

For installation close to walls the physical influences of the building must
be considered. No windows or doors should be present in the area
surrounding the air outlet of the ventilator.

ATTENTION!

In cases of installation close to a wall, there may be more sediment in the
air inlet and outlet areas due to the air current. The colder outside air
outlet should discharge in such a way as to not increase the heat losses
in heated neighbouring rooms.

ATTENTION!

Installation in a hollow or in an inner courtyard is not permitted because
cooled air collects at ground level and is drawn in again by the heat pump
during lengthy operation.

ATTENTION!

The dirt trap included in the scope of supply is to be installed in the heat
return before the heat pump.

ATTENTION!

Ensure that there is a clockwise rotating field: With incorrect wiring the
starting of the heat pump is prevented. A corresponding warning is
indicated on the display of the heat pump manager (adjust wiring).

ATTENTION!

Never use cleaning agents containing sand, soda, acid or chloride as
these can damage the surfaces.

ATTENTION!

We recommend the installation of a suitable corrosion protection system
to prevent the formation of deposits (e.g. rust) in the condenser of the
heat pump. We recommend equipping diffusion-open heating systems
with an electrophysical anti-corrosion system (e.g. ELYSATOR system).

ATTENTION!

Before opening the device, ensure that all circuits are powered down.

ATTENTION!

Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.

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 manufacturer's
product information. Please refrain from tampering with or alte-
ring the device.

1.3 Legal regulations and

directives

The construction and design of the heat pump complies with all
relevant EU directives, DIN/VDE regulations (see CE declaration
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
further connection requirements stipulated by the network opera-
tor must also be observed.
When connecting the heating system, all applicable regulations
must also be adhered to.
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or due to their inexperience or lack of knowledge, must not ope-
rate 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.

ATTENTION!

For devices with a refrigerant quantity of 6 kg or more, the refrigerating
circuit must be checked for leaks each year in compliance with regulation
(EC) No. 842/2006.

More information can be found in the chapter Cleaning / mainte-
nance.

1.4 Energy-efficient use of the heat

pump

By operating this heat pump, you are helping to protect the envi-
ronment. A prerequisite for energy-efficient operation is the cor-
rect design of the heat source system and heating system.
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and heat
source as small as possible. For this reason, it is advisable to de-
sign the heat source and heating system very carefully.

A tem-

perature difference of approx. one Kelvin (one °C) increases
the power consumption by around 2.5 %.

When designing the

heating system, it should be borne in mind that special consu-
mers such as e.g. domestic hot water preparation should also be
taken into consideration and dimensioned for low temperatures.

Underfloor heating systems (panel heating)

are optimally sui-

ted 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 conta-
minated during operation because this increases the tempera-
ture difference, in turn reducing the COP.
