4 Operating the Equipment
4.1
Starting the equipment
1 Ensure that the isolation valves on the inlet and the outlet of the unit are closed.
2 Slowly open the isolation valve on the inlet of the unit and verify that there are no leaks.
3 Check that the system pressure relief valve is closed.
4 Test the condensate drains of the filters and ensure they are discharging correctly into a suitable collection vessel.
5 Slowly open the outlet isolation valve to allow the system to pressurise. Do not open the valve fully until the down stream system has
reached the correct operating pressure.
The unit is designed for continuous use and, once running, requires no further operator intervention.
4.2 Shutdown
To depressurise the unit
1 Close the isolation valve on the outlet followed by the isolation valve on the inlet.
2 Slowly open the drain ball valve on the outlet dust filter to depressurise the unit.
Note: A small amount of air may be trapped between the inlet isolation valve and the equipment inlet.
