Operating
• Do not block or alter the relief valves adjustment, in order to
avoid damage or explosion.

• Keep the rotation speed withing the given limits.
In case of any obstruction along the suction line stop the
pump and remove the cause.
Do not adjust the flow by means of gate valves or relief valves
which are not suitable for such purpose. The flow and the
vacuum rate can be adjusted changing the speed of the
pump.

The pump must be stopped while cleaning the suction filter.
The filter can be cleaned using detergent liquid,
and a high pressure jet of air.
