P.32

6.1 Preparations for Operation

1) Check if electric wiring is properly performed.
2) Check if the inlet pipe and the outlet pipe are securely connected. When a valve is installed on the
outlet side, open the valve securely before starting the pump.
3) Make sure good ventilation for the pump is secured.

6.2 Operation and Stop

Pump remains hot during and/or after operation. Avoid direct skin contact otherwise it may
cause burn. Keep combustible materials away from the product. Do not attempt to service the
product when it is hot.
Do not remove packaging covers during operation.
Use gas ballast mechanism and introduce ballast gas into the pump during operation when
pumping condensable gases.
* Close the cut-off valve on the inlet port side of the pump when needed.
(To keep the vacuum system in vacuum, it is necessary to install shut-off valve between the system and
the pump. Close this valve before the pump stops.)
* When condensable gas such as water vapor has been pumped, please keep the pump running
opening the inlet port for about one hour after pump operation.
Corrosion in the pump can be prevented by removing the residual with dry air.
As the pumped gas quantity is larger, perform the dry air pumping for a longer time.
* If there is an open/close valve on the outlet port side of the pump, close this valve.
