When pumping toxic gases replace the gas ballast switch with a plug screw
or connect a gas supply to the gas ballast.
3.3 Connecting the Pump
Remove the blank flanges. We recommend that you retain the blank flanges
for decommissioning of the pump.
During installation work on the intake and discharge lines do not subject
flanges to any stresses.
Intake side
At the intake side, connect a hose to the vacuum chamber. Do not damage
the sealing surfaces of the connecting flanges.
Do not allow the ingestion of any objects (screws, welding beads, nuts,
washers, pieces of wire, etc.) through the intake port of the pump.
The intake line must be clean. Deposits in the intake line can degas and
impair the vacuum. The connecting flanges must be clean and undamaged.
