10. Troubleshooting

10.1 Troubleshooting (1) Basic trouble

WARNING

Interrupt Earth Leakage Breaker (ELB) before starting on

wiring and maintenance work.

Do not switch on the power supply to the pump until work is
completed.

WARNING

The pump casing and exhaust piping become extremely hot

during operation and for some time after stopping.

Be sure that pump and exhaust piping do not come in contact
with humans or inflammable substances.

Do not remove the pump cover during operation.

WARNING

Check for gas leaks after installing and maintaining the piping.

Gas leaks will result in the discharge of harmful and
dangerous substances and in abnormal reactions due to the
ingress of air into the pump. When checking for gas leaks by
pressurization,

please pressurize by less than 0.05 MPa into

the purge port and do check.
