Safety

z

A suitably trained and supervised technician must install the Silencer.

z

Ensure that the installation technician is familiar with and complies with the safety procedures which relate 
to the products processed by the pumping system. Wear the appropriate safety-clothing when you come into 
contact with contaminated components. Dismantle and clean contaminated components inside a fume-
cupboard.

If the GV pump has been in operation, vent and purge the process system, then shut down the GV pump and 
allow it to cool to a safe temperature before you start installation.

z

Disconnect the GV pump and the other components in the process system from the electrical supply so that 
they cannot be operated accidentally.

Use suitable lifting equipment to move the Silencer.
