Commissioning
NOTICE!
Commissioning should only be performed by
specially trained personnel and documented
after the certificate has been issued.
NOTICE!
Observe the manuals for the unit and all other
components when commissioning the entire
system.
Function test for cooling operating mode
1.
Switch the power supply on.
2.
Open all shut-off valves if necessary.
3.
Switch on the chiller and the corresponding
circulation pump. The outlet temperature
must be between 0 °C and +18 °C.
4.
Switch the unit on and select the cooling
operating mode. If the return temperature is
warmer than the setting, the compressor dis-
play will flash and the compressor will begin
to work after a short time.
5.
Please note that the inlet temperature at the
nominal flow rate of the medium lies approx.
5 K below the return temperature.
If the spread between medium inlet and
medium outlet is too large or too small, the
medium flow rate must be checked and
adjusted by means of settings on the
hydronic balancing valve(s).
- The circulation pump starts and the con-
troller checks the medium flow rate via the
flow switch. If the volume is insufficient, a
fault shut-off will be carried out and the
cooling cycle will not be enabled.
6.
Measure and record all the required values in
the commissioning report and check the
safety functions.
7.
Check the unit control system using the func-
tions described in the "Operation" chapter.
Final tasks
n
Mount all removed parts.
n
Familiarise the operator with the system.
The delivery of the unit from the factory takes
place with standard parameterisation of the
output control. If necessary during commis-
sioning a system-specific parameterisation
must be carried out by authorised personnel.
