SUPPLY
Water is fed using a centrifugal pump. The pump should not be sucking against the inlet opening, but should rather be “under
positive suction head”, i.e. under the pressure of a water column due to the difference in height between water level in the
collection tank and the pump.
Consider a water head of at least 1 metre to ensure pump proper suction.
ATTENTION
–
Avoid using water delivery at a temperature below 60°C because it would be rich in dissolved oxygen and cause corrosion.
Version with supply unit (optional)
The generator can be equipped with an assembly consisting of Softener and Condensate collection tank, which is located,
together with the switchboard, onto a suitable base next to the boiler.
Softener
The softener is of the cabinet type with automatic regeneration control. The cylinder containing resin and brine tank are contained
in a single appliance that also includes the mixing valve for residual hardness adjustment.
For more information on the softener, refer to the relevant manual supplied with the unit.
