Completion and commissioning
11.1 Before initial start-up
The heat pump has no separate ON/OFF switch. In an
emergency, the system must be shut down via the specified
safety device. The safety device must be accessible so that
an emergency shutdown can be performed at any time.
WARNING: Electrocution
The initial start-up of electrical systems is permitted
only in the presence of a qualified contractor.
»
Make sure that no one can be put at risk during the
initial start-up.
»
Make sure that the heat sink system (heating and
DHW heating) has been connected to the heat pump.
»
Make sure that the hydraulic system is filled with
water.
»
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.
11.2 Testing the control circuit
Once all the above conditions have been checked, the
control circuit (OTE controller, 230 V AC) can be switched
on so that the individual functions can be tested.
»
Check all the sensors and their values for accuracy.
»
Check all controller outputs used in your hydraulic
system for correct function.
12. Completion and commissioning
OCHSNER Customer Service or an authorised customer
service partner must be requested to complete and com-
mission the system. Commissioning appointments must
be requested at least 2 weeks in advance.
12.1 Requirements
Before commissioning, the system installer must ensure
the following points:
► The design and installation of the system have been
approved by OCHSNER.
► The machine-specific engineering and installation
information has been observed (system installed ac-
cording to OCHSNER standard hydraulic schematics
or an OCHSNER special hydraulic system).
► The minimum area of clear floor space in the installa -
tion room for the indoor unit has been observed.
► For heat pumps with OTE controller:
- The system datasheet is available and has
been fully and correctly completed.
► For air/water heat pumps:
- The outdoor unit has been correctly installed
and bolted to the foundation.
- If there is a snow cover, it has been correctly
installed on the outdoor unit.
1. The heat sink system is fully ready (heating and
DHW heating).
► The hydraulic pipework has been correctly dimen-
sioned and installed so that the required flow rates
can be set.
► The heat sink system has been flushed, filled and
vented according to the relevant standards.
► System fill water of a quality compliant with the rel -
evant standards (e.g. VDI 2035) is assured.
► The operating pressure has been set (0.8-2.0 bar).
► The system temperature or the buffer tem -
perature must be at least 15°C at the time of
commissioning.
Information
If the minimum system temperature or the buffer
temperature is not achieved, then the refrigerant
charge cannot be set correctly. Non-compliance
with the minimum system temperature or the buff -
er temperature will lead to commissioning being
cancelled.
»
If necessary, use preheating on site.
► The necessary safety devices are in place and
have been adjusted and checked according to sys-
tem requirements.
► A DHW tank is present and has been filled for
commissioning.
► All shut-off valves have been opened, adjusted
and checked.
► The flow meters installed on site have been
checked for correct function.
► The system has been hydraulically balanced.
2. The heat source system has been prepared.
► If hydraulic pipework is fitted on the heat source
side, it has been correctly dimensioned and in-
stalled so that the required flow rates can be set.
► The necessary safety devices are in place and
have been adjusted and checked according to sys-
tem requirements.
► The wall conduit has been properly sealed.
