Observe the external and internal dimensions as specified in the figure. Also ensure that the vibration and duct isolation are ade- quate.
6.3Heating System Connection
To enable connection to the heating system, flexible hose con- nection pieces and double nipples with a 1" external thread are included with the heat pump. These allow the optional use of a threaded or flat gasket connection to the heating system.
If the heat pump is not intended to be used to heat up the hot wa- ter, the hot water output must be permanently sealed using the supplied sealing plug.
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.

An overflow valve is installed in the device for systems in which |
| |
the heating water flow can be shut off via the radiator or thermo- |
| |
stat valves. 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 |
| |
The integrated expansion vessel has a volume of 24 litres. This |
| |
volume is suitable for buildings with a living space area to be |
| |
heated of maximum 200 m². |
| |
The volume should be checked by the heating system engineer. |
| |
If necessary, an additional expansion vessel must be installed |
| |
(according to DIN 4751, Part 1). The tables listed in the manufac- | English | |
turers' catalogues simplify dimensioning the system on the basis | ||
of the water content. Allow for a buffer tank volume of 80 litres | ||

when making the calculation. |

ATTENTION!
In the case of
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 pumps 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:
A disconnecting device with a contact gap of at least 3 mm (e.g. utility blocking contactor or power contactor) as well as a
The control voltage must be protected by a 10 A fuse. See Ap- pendix Circuit Diagrams for detailed information.
