4.7

Shut down

Use the procedure below to shut down the pump:

1.

If shutting the pump down prior to a period of

storage, remove any process gases by running

on high flow gas-ballast for at least one hour.

2.

Close any vacuum system isolation valve to

prevent suckback into the vacuum system

(where fitted).

3.

Switch off the pump using the on/off switch.

When the pump is switched off the fan will

continue to run for 1 minute. 

4.

Vent the XDS35i by the gas ballast control or

valve on the inlet.
