1.1 Important Information
CAUTION! Any work on the heat pump may only be performed by an authorised and qualified customer service.
CAUTION! The transport securing devices must be removed after the transport.
CAUTION! The heat pump must not be tilted more than max. 45° (in either direction).
1.2 Legal Provisions and Guidelines
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 relevant VDE, EN and IEC standards. Beyond that, the connection requirements of the local utility companies have to be observed.
The heat pump is to be connected to the heat source and heat distribution systems in accord- ance with all applicable provisions.
CAUTION! Any work on the heat pump may only be performed by an authorised and qualified customer service.
CAUTION! Flush the heating system prior to connecting the heat pump.
CAUTION! The supplied strainer is to be fitted in the heat source inlet of the heat pump to protect the evaporator against contamination.
CAUTION! The brine solution must consist of at least 25 % of a frost and corrosion protection agent on a monoethylene glycol or propylene glycol basis.
CAUTION! The clockwise phase sequence must be ensured when connecting the load lines.
CAUTION! Commissioning of the heat pump must be performed in accordance with the installation and operating manual of the heat pump controller.
CAUTION! All electrical circuits must be dis- connected from the power supply prior to opening the unit.
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
