COMMISSIONING
8.1 General Information
To ensure proper commissioning it should be
carried out by an after-sales service authorized by
the manufacturer. Only then can an extended
warranty period of 3 years in total be granted (cf.
Warranty service).
8.2 Preparation
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
could impair the proper heating water 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.
8.3 Commissioning Procedure
The start-up of the heat pump is effected via the heat
pump controller.
Commissioning of the heat pump
must be performed in accordance with the
mounting 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 requirements 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 following procedure is recommended:
a) Open all heating circuits and close the overflow
valve. Determine the resulting temperature
difference between supply and return flow.

b) Close all of the heating circuits that may also be
closed during operation (depending on the type
of heat pump usage) so that the most unfa-
vourable operating state - with respect to the water
flow rate - is achieved.
c) In this operating state open the overflow valve
until approximately the same temperature
difference exists that was measured under a)
when the overflow valve was closed and the
heating circuits open.
Any malfunctions occurring during operation are
displayed on the heat pump controller and can be
corrected as described in the operating manual of
the heat pump controller.
