Information
OCHSNER customer service or a customer ser-
vice partner carries out customer-specific settings
according to the details on the system datasheet.
If the system installer is not present during com-
missioning or if a fully completed system datasheet
is not available, the system is put into operation
using the control factory settings. OCHSNER will
accept no responsibility for any faulty operation
(too low a heating curve, too high a bivalent point,
etc.). Any additional work required will be charged
to the system installer.
11.6 Commissioning the system
Before commissioning, the relevant requirements must be
met. (see page 36, Necessary conditions for commis-
sioning)
Commissioning is carried out by OCHSNER customer
service or by a customer service partner authorised by
OCHSNER. The OCHSNER commissioning guidelines
apply.
i
Information
If the system is operated without technically correct
commissioning in accordance with the OCHSNER
guidelines, all warranty claims will be invalid.
i Information
Special work such as system venting, connecting
electrical cables, additional training, etc., which is
not included in OCHSNER‘s scope of delivery, will
be invoiced separately.
Activities carried out by OCHSNER:
► Checking that the system has been installed accord-
ing to OCHSNER guidelines. In commissioning the
system, OCHSNER offers no warranty regarding the
ability to meet the heat demand of the building to be
heated.
► Functional testing of the heating circuit (system pres-
sure, function of diaphragm expansion vessel, volume
settings). Responsibility for the system remains with
the system installer.
► Checking the flow rates.
► Checking that all shut-off valves are open.
► Checking the electrical connections to the system
components including all required safety devices.
► In the case of air/water and direct evaporation/water
heat pumps (depending on contractual terms):
► Version 1:

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 con-
nection points on the indoor and outdoor units.
- Charging the system with the correct refriger-
ant according to OCHSNER guidelines.
► Version 2:
Where connection lines have been laid and the
technical installation of the refrigerant circuit car-
ried out by OCHSNER Customer Service.
