Pressure Vessel
The air pre-charge in the pressure vessel should be set 65% of the pre-set working pressure for maximum
eff ectiveness. It is recommended to check the tank air pressure every 4-6 months. The vessel can be
charged with an air source via an inlet valve. The pressure can be checked using a suitable pressure
gauge. Air can be added or released as required in order to adjust the percentage of pressure.
In order to check the air pressure in the vessel, it is necessary to release the pressure in the vessel
To do this:
1.
The isolation valve below the vessel must fi rst be closed
2.
The drain valve is opened to release water pressure
3.
The air pressure is tested with a suitable gauge at the air valve
4.
Add or release air depending on the pressure reading
5.
When the pressure has been adjusted, close the drain valve and open the isolation valve to
return the set to service
