1.1 Important Information
CAUTION! The heat pump is not secured to the wooden pallet.
CAUTION! The heat pump must not be tilted more than max. 45° (in either direction).
CAUTION! Do not lift unit by the holes in the panel assemblies!
CAUTION! In the case of
CAUTION! The brine solution must contain at least 25 % of an antifreeze and corrosion protection agent on a monoethylene glycol or propylene glycol basis.
CAUTION! On connecting the electrical load lines, the clockwise phase sequence must be observed (in the case of an incorrect phase sequence the heat pump will deliver no output and generate a lot of noise).
CAUTION! Commissioning of the heat pump must be performed in accordance with the installation and operating manual of the heat pump controller.
CAUTION! Caution - Heating Contractors ! Depending on the filling water quality and quantity, in particular in the case of mixed installations and plastic pipes, mineral deposits (rust sludge, lime) may form, impairing the pro- per functioning of the heating installation. A reason for this is the water hardness and oxygen dissolved in the filling water as well as additional oxygen from the air, which may penetrate via valves, fittings and plastic pipes (oxygen diffusion). As a preventive measure it is recommended that a physical water conditio- ner such as ELYSATOR be used.

CAUTION! The supplied strainer is to be fitted in the heat source inlet of the heat pump in order to protect the evaporator against contamination.
CAUTION! Any work on the heat pump may only be performed by authorised and qualified customer service agents.
1.2 Legal Provisions and Directives
This heat pump conforms to all relevant DIN/VDE regulations and EU directives. For details refer to the EC Declaration of Conformity in the appendix.
The electrical connection of the heat pump must be performed according to and conforming with all re- levant VDE, EN and IEC standards. Beyond that, the connection requirements of the local utility compa- nies have to be observed.
The heat pump is to be connected to the heat source and heat distribution systems in accordance with all applicable provisions.
1.3Energy-Efficient Use of the Heat Pump
By operating this heat pump you contribute to the protection of our environment. A prerequisite for an efficient operation is the proper design and sizing of the heating system and the heat source system. In particular, it is important to keep water flow temperatures as low as possible. All energy consumers connected should therefore be suitable for low flow temperatures. A 1 K higher heating water temperature corresponds to an increase in power consumption of approx. 2.5 %. Underfloor heating systems with flow temperatures between 30 °C and
40°C are optimally suited for
