Completion and commissioning
► In the case of air/water and direct evaporation/
water heat pumps, if the laying of the connec-
tion lines has been contractually agreed by
the system installer:
- The refrigerant lines between the indoor and
outdoor units have been correctly routed in
accordance with refrigeration engineering
guidelines.
- The refrigerant lines have been correctly
channelled through the wall conduit with some
surplus length between the connections at the
indoor and outdoor units.
► In the case of brine/water heat pumps:
- The system pressure and addition of frost
protection additive (between -12°C and -15°C)
have been assured.
- The heat source system has been flushed,
filled and vented according to the relevant
standards.
► In the case of water/water heat pumps:
- All filters have been checked and cleaned.
- The water quality is in accordance with OCHS-
NER guidelines.
Information
OCHSNER accepts no liability for damage (e.g. to
plate heat exchangers) caused by poor water qual-
ity.
3. The electrical installation has been completed.
Information
Temporary electrical installations are not permissi-
ble and will lead to commissioning being cancelled.
► Electrical connection and installation work has
been carried out and completed in accordance
with national and regional regulations.
► Tests in accordance with national and regional
regulations have been carried out (e.g. test report
for electrical systems)
► A safety device that will shut down across all poles
has been provided on every supply (compressor,
heat source pump and controller). Every additional
heat generator is also provided with its own safety
device.
► The indoor unit and an existing outdoor unit are
wired correctly.
► The indoor unit is correctly earthed. (Main electri-
cal circuit, control circuit, equipotential bonding of
the refrigerant lines via the equipotential bonding
connection)
► The three-phase supply has been checked to en-
sure a clockwise rotating field.
► For air/water heat pumps
- The outdoor unit is correctly wired.
- The outdoor unit is correctly earthed (outdoor
unit supply).
4. On site requirements.
► An authorised and technically competent repre-
sentative of the system installer (the heating or
electrical contractor) is present along with the sys-
tem user during the commissioning.
► Customer-specific controller settings (for example
required heating curve and functional logic) are
available.
► Where connections are in a shaft or on the roof,
an assistant is provided by the customer.
► Climbing aids and fall protection (including compli-
ant attachment points) must be provided on site in
accordance with the relevant standards.
► Vehicle access to the heat pump system must be
available.
► For heat pumps with OTS controller:
The heat pump has a stable internet connection.
Information
OCHSNER Customer Service or a customer ser-
vice partner carries out customer-specific settings
according to the system installation specifications.
If the system installer is not present during com-
missioning, or the corresponding specifications are
not available, the system is commissioned using
the factory settings of the controller. OCHSNER
will accept no responsibility for any faulty operation
(for example heating curve too low, bivalent point
too high, etc.). Any additional work required will be
charged to the system installer.
12.2 System completion
System completion is dependent on the contractual rela-
tionship.
► Version 1:
Where connection pipes have been laid as contrac-
tually agreed by the system installer. OCHSNER
customer service is responsible for:
► Connecting the previously laid refrigerant lines.
► Conducting leakage tests on the refrigerant lines.
► Evacuating the refrigerant lines.
► Insulating the refrigerant lines around the connec-
tion points on the indoor and outdoor units.
► Charging the system with the correct refrigerant
according to OCHSNER guidelines.
