4. Commissioning
1. The height of lift for the control valve is automatically
calibrated the first time it is commissioned.
2. Check the pre-pressure by measuring the level dif-
ference from the centre of the expansion vessel to the
highest point of the pipe connection system. Convert the
level difference to bar (1 metre = 0.1 bar). Add another
0.3 bar (for the coil) to this figure to obtain the pre-pres-
sure.
The safety valve must be sized to withstand at least 1 bar
above the pre-pressure. The safety valve supplied is sized
to withstand 2.5 bar.
Example:
Measured level difference of 2 metres = 0.2 bar
Pre-pressure = 0.2 bar + 0.3 bar (coil) = 0.5 bar
Min. permissible safety valve pressure = 0.5 bar + 1 bar =
1.5 bar
This figure is well below the max. limit of the safety valve
supplied, which is 2.5 bar.
Equipped with the safety valve supplied, the pipe connec-
tion system will manage a level difference of 12 metres (=
1.2 bar).
If the level difference is more than 12 metres, you will
either have to move the expansion vessel with accessories
to a higher position or replace the safety valve. Since the
expansion vessel manages max. 5 bar, a safety valve sized
for a max permissible pressure of 5 bar must be used.
The expansion vessel is factory-rated for a pre-pressure of
0.5 bar, which also is the minimum limit. If the pre-pres-
sure of the expansion vessel threatens to drop below 0.5
bar, fill more air through the nipple on the underside of
the expansion vessel.
3. Preset the adjustable red pointer on the manometer, to
the corrected pre-pressure in the expansion vessel.
4. Open "the cap" on the automatic air purging valve.
5. Fill the system with water (usually water mixed with
glycol). Please note that if glycol is used, it must be meant
for cooling medium systems, not motor vehicles. Fill the
system slowly. Vent the liquid circuit at the air purging
points as you fill it.
6. Adjust (fill / drain) the system so that the pressure in the
system will conform to the corrected pre-pressure reading
(see the red pointer on the manometer).
7. The system is now ready to be commissioned. Under
normal operating conditions, the pressure in the system
must not drop below the corrected pre-pressure preset on
the manometer (see the red pointer on the manometer) or
exceed the red mark.
