11. Commissioning
OCHSNER Customer Service or an authorised custom-
er service partner must be requested to commission the
system. In order to be allocated an appointment, a com-
pleted and signed commissioning form must be provided.
Commissioning appointments must be requested at least
two weeks in advance.
11.1 Before switching on for the first time
The heat pump has no separate on/off switch. In an emer-
gency, the system must be shut down via the specified
safety equipment. The safety equipment must be acces-
sible so that an emergency shutdown can be performed
at any time.
WARNING: Electrocution
First-time start-up of electrical systems is permitted
only in the presence of a qualified contractor.
»
Make sure that no persons can be put at risk during
the first start-up.
»
Make sure that the heat sink system (heating and
DHW production) has been connected to the heat
pump.
»
Make sure that the hydraulic system is filled with
water.
»
Make sure that the system has been fully vented.
»
Make sure that the electrical installation has been
carried out and completed professionally.
Material damage
Operating the circulation pumps without water in
the system will destroy the pumps.
The power supply to the main power circuit (compressor)
must not be switched on until the refrigerant circuit has
been filled with refrigerant and the hydraulic system with
the correct medium.
11.2 Testing the control circuit
Once all the above conditions have been checked, the pow-
er supply to the control circuit (OTE controller, 230 VAC)
can be switched on so that the individual functions can
be tested.
»
Check all of the sensors and their values for
plausibility.
»
Check all of the controller outputs used on your hy-
draulic system for correct function.
11.3 Adjusting the flow rate
The nominal flow rate of the heat sink system must be
determined in each operating mode (DHW charging, heat-
ing, cooling mode via separate cooling heat pump buffer
tanks etc.). The flow rate is measured using the installed
flow meter. The measured values can be read off from the
master controller display on the indoor unit.
The flow rate of the heat sink system is adjusted using the
adjusting screw on the heat generator pump (HGP). To
enable correct hydraulic adjustment, in particular during
combined heating or heating/cooling and DHW heating
modes, the appropriate balancing valves must be installed
and the system regulated accordingly.

i Information
To be able to change the flow rate in the heat sink
system, you will have to turn the adjusting screw
on the heat generator pump.
»
Remove the front casing panel from the indoor
unit to gain access to the heat generator pump
(see „Disassembling the appliance casing“ on
page 26).
»
Switch on the heat generator pump via the relay test
menu on the master controller.
