6.3Heating and Hot Water

Connection

The heating system connections on the heat pump have a 1" ex- ternal thread. Use a spanner to firmly grip the transitions when connecting the heat pump.

Before connecting the heating water system to the heat pump, the heating system must be flushed to remove any impurities, residue from sealants, etc. Any accumulation of deposits in the liquifier could cause the heat pump to completely break down. For systems in which the heating water flow can be shut off via the radiator or thermostat valves, an overflow valve must be in- stalled by the customer in a heating bypass downstream from the heat pump. This ensures a minimum heating water flow rate through the heat pump and helps to avoid faults.

Once the heating system has been installed, it must be filled, de- aerated and pressure-tested.

Minimum heating water flow rate

The minimum heating water flow rate through the heat pump must be assured in all operating states of the heating system. This can be accomplished, for example, by installing either a manifold without differential pressure or an overflow valve. The procedure for adjusting an overflow valve is described in the Chapter Start-up.

Antifreeze

A method of manual drainage (see illustration) should be pro- vided for heat pumps which are exposed to frost. The antifreeze function of the heat pump controller is active whenever the con- troller and the heat circulating pump are ready for operation. If the heat pump is taken out of service or in the event of a power failure, the system has to be drained. The heating circuit should be operated with a suitable antifreeze if heat pump systems are implemented in buildings where a power failure can not be de- tected (holiday home).

6.4Electrical Connection

The power supply and control voltage are supplied using stand- ard cables (load: 4-core, control: 3-core).

An all-pole disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) as well as a 3-pole circuit breaker with common tripping for all external conductors must be installed in the power supply (tripping current in compliance with the Device Information).

Ensure that the incoming supply has a clockwise rotating field when connecting multiphase devices L1; L2; L3.

ATTENTION!

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

The control voltage must be protected by a 10 A fuse.
