4. Operation 

4.1 Caution on Operation 

 

 

WARNING 

 

This pump is not pressure-proof. 

Never  run  the  Vacuum  pump  on  blocking  up  the  exhaust  outlet, 

putting any device that hampers the gas passage or putting any oil 

mist trap not conforming to the ULVAC pump. There is a risk that the 

pressure inside the rises up as far as the Pump unit and/or Oil level 

gauge breaks or the Motor gets overloaded. 

 

This  product  is  not  made  as  the  withstand  pressure  structure. 

Ensured pressure value of the Pump shall be 0.03MPaG (0.3kg/cm2

G

(Gauge pressure). 

 

If  any  valve  was  put  to  a  pipe  after  the  Exhaust  outlet,  check  and 

ensure that it is open. 

 

 

CAUTION 

 

1) The Pump oil might deteriorate in a shorter time depending on the 

use. 

It  is  recommended  to  replace  the  first  Pump  oil  within  ten  days 

after operation start and see how it got dirty to determine the oil 

replacement cycle. 

 

2)  If  the  Pump  breathes  in  a  lot  of  water  or  the  like,  you  should 

replace  the  oil  more  frequently.  If  kept  operation  without  getting 

rid of breathed water, it would deteriorate lubrication of the oil and 

further help corrosion of the Pump inside and result in causing a 

failure. 

Do not store the product keeping sucked the water. 

 

3)  If  the  Pump  breathed  in  chemical  material  such  as  acid, 

immediately replace the oil as it would cause the rust during the 

stop in one night to make the system e not applicable to operate. 

We shall be not liable to the durability to chemical material.
