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 0.03MPa (0.3kgf/cm
2
) (Gauge pressure).
If any valve was put to a pipe after the Exhaust outlet, check and ensure that it
is open.
WARNING
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.
CAUTION
Never fail to conduct the lubrication oil deaeration before starting operation
when lubricated anew the Mechanical booster pump or left it a long time after
lubrication.
Starting operation without deaeration might generate a lot f bubbles and cause
them flow in the Rotor chamber.
CAUTION
Never fail to flow the coolant during operation, Required coolant volume shall
be;
