1.1Important Information:

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!

The heat pump and transport pallet are only joined by the packing film.

ATTENTION!

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

1.2Legal 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 fulfilled. Any further connection requirements stipulated by local utility companies 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 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.

ATTENTION!

Only operate the heat pump with the air ducts connected.

ATTENTION!

Ensure that there is a clockwise rotating field: Operating the compressor in the wrong rotational direction could cause damage to the compressor.

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.

ATTENTION!

Before opening the device, ensure that all circuits are isolated from the power supply.

ATTENTION!

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

1.3Energy-Efficient Use of the

Heat Pump

With the purchase of this heat pump you are helping to protect the environment. A prerequisite for energy-efficient operation is the correct design of the heat source system and heating system (radiators and circulation pump).

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 increases the power consumption by around 2.5%. When designing the heating system, it should be borne in mind that special consum- ers such as e.g. hot water preparation should also be considered and dimensioned for low temperatures. 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 because this increases the tempera- ture difference, in turn reducing the COP.

Correct adjustment of the heat pump controller is also important for energy-efficient use of the heat pump. Further information can be found in the heat pump controller's operating instructions.
