4. Operation
4.1 Cautions on operation
Do not suck in non-inert gasses.
Do not use non-inert gasses (toxic gas, combustion gas, combustion-
supporting gas, corrosive gas, explosive gas) as this machine is supposed to
discharge inert gasses (air, nitrogen, argon) and discharging other gasses
may cause leakage of these gasses from the pump main unit, or may cause
ignition or explosion inside the pump.
Do not suck in toxic gasses.
If this machine sucks in a toxic gas, not only the pump main unit but also the
lubricating oil may become poisonous. Be careful to this at the time of
maintenance work.
Do not use the machine at a place where dangerous atmosphere may be
generated.
Do not use the machine at a place where dangerous atmosphere may be
generated by explosive gasses. Ignorance to this may cause injury or fire
breakout.
Do not cover the exhaust port.
Do not operate the machine while attaching a device that may interfere in the
passage of gasses on the exhaust port side such as covering the port.
This may raise the inner pressure of the machine and may end up in blowout
of casing or oil leakage, or overload on the motor. The machine structure is
not designed to withstand pressures. The resisting pressure guaranteed value
of the pump is 0.03 MPaG (0.3 kg/cm2G) (gauge pressure).
In front of the ventilation opening, take a clearance of 0.5m or more
If there is a wall or an obstacle within 0.5m from the ventilation opening,
abnormal overheat may occur which may cause burn or fire breakout.
Use the machine with the face panel attached.
The performance of the machine may be deteriorated if the machine is
operated without the face panel attached. Never fail to use the machine with
the face panel attached. The discharge performance cannot be fully
demonstrated soon after the startup or without the face panel attached.
Do not suck in chemicals such as acid
Suction of chemicals such as acid may disable the operation of the machine.
