ground.

· The pump unit is not equipped with circuit breaker (CB). Please install CB based on

the law and the standard in the installation region.

· The pump must be connected to electrical power supply with a suitable circuit

beaker (lockout / tagout CB).

· Be sure to check for leaks after you have installed the pump. When checking for

gas leaks by pressurization, please pressurize by less than 0.05 MPa into the

exhaust piping.

· This pump is suitable for use on clean and non-corrosive gases. Do not use

explosive, flammable, toxic or corrosive substances.

· The pump and exhaust piping will remain at a high temperature during operation

and for a short time after the pump has stopped. Be sure to avoid contact and keep

inflammable substances out of reach. Do not remove the pump cover during

operation.

· Be sure to wire all signals with the correct polarity (+/-).

· When output signals are used to energize an inductive load such as a relay, be sure

to insert a diode (100V. 1A class) in order to absorb the back electromotive force due

to surge currents.

· The pump cannot start while the measuring instruments are booting after the ＣＰ is

placed in the ON position.
