10. ADJUSTMENT AND COMMISSIONING
General information
PLEASE NOTE! Some models may have a slightly different appear-
ance, but the control function is in principle the same as described
below.
Commissioning
Commission the substation in accordance with the instruction
manual.
Filling the system / operating pressure
Fill the unit with water according to the instructions on page 11.
If the pressure drops below 1 bar, water must be added to the sys-
tem.
The operating pressure should never exceed 1.5 bar.
(The safety valve opens at 2,5 bar).
The pressure is read on the manometer.
If system pressure drops dramatically within a short time, heating
system should be examined for leakage, - this includes checking
the factory set pressure of the expansion vessel, which is normally
0,5 bar.
Differential pressure controller
For Akva Lux II VXe the differential pressure controller is installed in
the AVQM self-acting flow controller with integrated control valve.
Please see page 16.
