0.3 Cautions for safety
This pump is for dry air or the dry nitrogen suck only.
Never allow people other than repair engineers to disassemble or repair the
pump. Failure to do so may result in ignition or malfunction, leading to injury
or electric shock.
Connect the earth wire correctly. It is recommended that a dedicated earth
leakage breaker should be installed. If the earth wire is not connected, there
is a possibility of electric shock occurring in the case of a malfunction
or electrical leakage.
There is a risk of explosion. Never block the outlet or operate the pump with
equipment mounted at the outlet side which blocks the passage of gas.
Otherwise, the internal pump pressure increases causing the pump to explode,
the oil level gauge to protrude or the motor to be overloaded.
This pump is not resistant to pressure. The internal pump pressure is limited
to 0.03 MPa (gauge pressure).
The Vacuum Pump Unit is device a built-in device. Do not install it without
adequate protection against heat hazard. The surface temperature of the
vacuum Pump Unit can exceed 90 degrees in case it is operated under high
pressure (atmospheric to 10kPa).
It gets an electric shock touching the motor energizing part. Please work
after pulling out the power plug without fail when wires electricity is
connected, it checks, and it transfers it.
