8 Commissioning

8.1General Information

To ensure proper commissioning it should be carried out by a customer service authorised by the manufacturer. This will lead, under certain circumstances, to an extension of the warranty pe- riod (cf. Warranty). Start-up should be carried out in heating op- eration.

8.2Preparatory Steps

Prior to commissioning, the following items need to be checked:

„All connections of the heat pump must have been made as described in Chapter 7.

„The heat source system and the heating circuit must have been filled and checked.

„The strainer must have been fitted in the sole inlet of the heat pump.

„In the brine and heating circuits all valves that might impair the proper flow must be open.

„The settings of the heat pump controller must be adapted to the heating installation in accordance with the instructions contained in the controller's operating manual.

8.3Commissioning Procedure

The start-up of the heat pump is effected via the heat pump con- troller.

ATTENTION!

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

Where an overflow valve is fitted to assure the minimum heating water flow rate, the valve must be set in accordance with the re- quirements of the heating installation. An incorrect setting may result in various error symptoms and an increased elec-tric power consumption. To correctly set the overflow valve, the fol- lowing procedure is recommended:

Close all of the heating circuits which may also be closed during operation (depending on the type of heat pump usage) so that the least favourable operating state - with respect to the water flow rate - is achieved. Normally, these heating circuits are those of the rooms located on the south and west sides of buildings. At least one heating circuit must remain open (e.g. bathroom).

The overflow valve is to be opened to such an extent that based on the current heat source temperature the maximum tempera- ture difference between heating supply and return flow tempera- ture is obtained, as indicated in the table below. The tempera- ture difference should be measured as closely to the heat pump as possible. In mono-energetic systems, the electric heating ele- ment is to be deactivated.
