1.1Important Information

ATTENTION!

Any work on the heat pump may only be performed by an authorised and qualified customer service.

ATTENTION!

The heat pump must not be tilted more than max. 45° (in either direction).

ATTENTION!

The transport securing devices must be removed prior to commissioning.

ATTENTION!

The heating system must be flushed prior to connecting the heat pump.

ATTENTION!

The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress of impurities.

ATTENTION!

The brine solution must contain at least 25 % of an antifreeze agent on a mono-ethylene glycol or propylene glycol basis and must be mixed prior to filling.

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 con- nected 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 %. Low-temperature heat- ing systems with flow temperatures between 30 °C and 50 °C are optimally suited for energy-efficient operation.

2Purpose of the heat pump

2.1Application

The brine-to-water heat pump is designed for use in existing or newly built heating systems. Brine is used as the heat carrier in the heat source system. Ground coils, ground collectors or simi- lar systems can be used as the heat source.

ATTENTION!

The clockwise phase sequence must be observed when connecting the load lines (the heat pump will deliver no output and will be very noisy when the phase sequence is incorrect).

ATTENTION!

Commissioning is to be effected in accordance with the installation and operating manual of the heat pump controller.

ATTENTION!

To prevent the accumulation of deposits (e.g. rust) we recommend using a suitable corrosion protection system.

ATTENTION!

Disconnect all electrical circuits from the power supply before opening the enclosure.

1.2Legal Provisions and

Guidelines

This heat pump conforms to all relevant DIN/VDE regulations and EU directives. For details refer to the EC Declaration of Con- formity 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 provi- sions.

ATTENTION!

Any work on the heat pump may only be performed by an authorised and qualified customer service.

2.2Principle of Operation

The heat generated by the sun, wind and rain is stored in the ground. This heat stored in the ground is collected at low temper- ature by the brine circulating in the ground collector, ground coil or similar device.

A circulating pump then conveys the warmed brine to the evapo- rator of the heat pump. There, the heat is given off to the refrig- erant in the refrigeration cycle. When so doing, the brine cools so that it can again take up heat energy in the brine circuit.

The refrigerant is drawn in by the electrically driven compressor, is compressed and "pumped" to a higher temperature level. The electrical power needed to run the compressor is not lost in this process, but most of the generated heat is transferred to the re- frigerant.

Subsequently, the refrigerant is passed through the condenser where it transfers its heat energy to the heating water. Based on the thermostat setting, the heating water is thus heated to up to 60 °C.
