MAXIMUM VOLUME OF WATER
Maximum volume of water in the system
Before filling the water system, it is advisable to consider the type of installation in question, i.e. check the difference in level
between the Pumping Module and user. The following table gives the maximum water content of the water supply system in
liters, depending on the capacity of the standard surge chamber supplied and the pressure at which it should be charged. The
surge chamber setting must be regulated to suit the maximum positive difference in level of the user.
Maximum setting
value
300 kPa
.
With a positive H of more than 12.25 meters, calculate the surge chamber’s service charge value in kPa using the formula
below:
Surge chamber service charge= [H/10.2+0.3] x100 = [kPa]
NOTE:
In case
A
, make sure that the user’s lowest point is able to withstand the global pressure.

NOTE :
If the unit operates with brine, the real volume of the system must be calculated by taking into account the correction
factors of the system’s volume as indicated in the table below.
