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.
