Clean up piping 

N

2

 pressure setting is high 

Set pressure for correct value 

Leakage from vacuum piping 

Check piping 

Vacuum pressure increase. 

Byproducts settled in pump 

Replace or overhaul pump 

 WARNING 

Interrupt Earth Leakage Breaker (ELB) or CB and lock out power 
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. 
Keep pump and exhaust piping away from contact with personnel and 
flammable 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 admission of air into 
the pump
