3.6 Checking Operation After Installation
1) Remove the rubber caps from the inlet and outlet.
2) Check that the pump switch is OFF, and insert the plug into the 100 V wall socket.
Note: Ensure that the power plug is sufficient for the rated voltage and current.
3) Turn the switch ON and check that gas is being drawn into the inlet.
4) When this check is complete, turn the power switch OFF to stop the pump.
3.7 Piping
1) Install piping carefully to prevent leaks.
2) Piping connected to the inlet should be at least 6mm inside diameter.
3) Maximum back pressure is 0.03 MPa (gauge pressure).
4) When evacuating a vessel, ensure that a shut-off valve is placed between the pump inlet pipe
and the vessel (see Fig.3).
5) When connecting a pipe to inlet / exhaust port, always hold the inlet / exhaust port by hands.
Also, hold the inlet / exhaust port by hands when detach the pipe.
6) In case of selecting the inlet pipe and exhaust pipe that are not from our products, please
select the exhaust pipe that has same or larger inner diameter length with the inlet pipe.

3.8 Storage
Turn the switch OFF, remove the power plug from the outlet, place the rubber caps over the inlet
and outlet, and store the pump in an area of low humidity.
4. Cautions for Operation
4.1 Cautions for Operation
1) It is necessary to clean internal pump when stopped operation in order to maintain the pump
performance.
Have the pump to absorb clean air for 3 - 5 minutes and conduct idling operation.
2) Consult the manufacturer if the pump is to be used in a special application.
