Commissioning
Commissioning procedure:
step 1
Determine the upper working pressure.
This upper working pressure is also the
set pressure of the overflow valve.
figure : determination of the upper and lower
3
working pressure
step 2
Shut all connections from/to system return (expansion overflow pipe, expansion
pressure pipe, makeup water)
: Do
shut suction pipe and overflow pipe at
series!
CAUTION
NOT
MCM
step 3
Fill and ventilate the system to the upper working pressure as determined in step 1.
step 4
Check the correctness of all hydraulic and electric connections, especially the
expansion pipe.
step 5
Open the makeup water connection to
makeup module and set the
MCF
pressure reducing valve to 1,5 bar - max. 2,0 bar.
Loosen the screw (1) at the pressure reducing valve
and set the scale to 1,5 bar - max. 2,0 bar.
To fix the setting, the screw must be tightened again.
NOTE!
Steps 1-3 must be completed on site in preparation for the commissioning.

NOTE!
Commissioning by the eder customer service resp. an authorized partner and training of
the operating personell is recommended!
