1.1 Important Information
CAUTION! Prior to opening the unit it must be ensured that all electrical circuits are disconnected from the power source.
CAUTION! During transport, the heat pump must not be tilted more than 45° (in either direction).
CAUTION! Heat pump and transport pallet are only connected by the packaging film.
CAUTION! The intake and outlet duct openings must not be restricted nor obstructed.
CAUTION! Clockwise phase sequence to be observed: Damage to the compressor may be incurred if it is operated in the wrong sense of rotation.
CAUTION! Do not use any cleaning agents containing sand, soda, acid or chloride as these may attack the surface.
CAUTION! To prevent consequential damage it is imperative that the water circuit be neutralized after cleaning using appropriate agents.
CAUTION! The unit is not suitable for operation with a frequency converter.
CAUTION! Work on the refrigeration circuit may be performed by qualified persons only.

1.2 Legal Provisions and Guidelines
This heat pump was designed and built in compliance with all relevant EU directives, DIN and VDE regulations (see CE Declaration 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 and cooling system, all relevant regulations have to be complied wit.
1.3Energy-Efficient Use of the Heat Pump
By purchasing this heat pump you contribute to the protection of the environment. A prerequisite for
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 applications such as domestic water heating are taken into consideration and dimensioned for low temperature operation. Heat pumps are optimally suited for underfloor heating (surface/radiant 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 an inferior 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.
