Commissioning - Kemper KHS CoolFlow 618 01 001 Manuel D'utilisation

Commissioning

Note!
Commissioning should only be
performed by specially trained
personnel and documented after
the certificate has been issued.
Observe the manuals for the
■
unit and all other components
when commissioning the entire
system.
Cooling function test:
1. Switch the power supply on.
2. Open all shut-off valves if nec-
essary.
3. Switch the unit on and select
the cooling operating mode.
If the return temperature is
warmer than the setting, the
compressor display will flash
and the compressor will begin
to work after approx. 3 to 5
minutes.
4. Please note that the inlet tem-
perature at the nominal flow
rate of the medium lies approx.
5 K below the return tempera-
ture.
- If the inlet temperature falls
below the factory setting of
4°C, a malfunction is issued.
If this is the case, a higher
return temperature must
be selected. If the spread is
too great or too small, the
medium flow rate must be
checked.
- The circulation pump starts
and the controller checks the
medium flow rate via the dif-
ferential pressure/flow switch.
If the volume is insufficient,
a fault shut-off will be carried
out and the cooling cycle will
not be enabled.
5. Measure and record all the
required values in the commis-
sioning report and check the
safety functions.
6. Check the unit control system
using the functions described in
the "Operation" chapter.
