(1) Before starting work, check that all dangerous energies are shut out.
(2) Wiring work shall be performed only by qualified personnel. Wrong
wiring work may trigger fire.
(3) Wiring work shall be performed correctly according to the safety
laws and regulations (such as fire laws, electric wiring codes, and
indoor wiring regulations) of the country and the local area where
you use this product.
(4) Securely connect to ground.
(5) We recommend installing a dedicated earth leakage breaker. There
is a risk of an electric shock.
(6) Be sure to attach an overload protective device. If not, it may result
in a motor burnout or fire.
Operation
(1) During the operation, do not touch the vacuum pump body, motor,
and pipes since they are subjected to high temperature. If your body
comes into contact with them, you may get burned.
(2) Do not operate the vacuum pump with any devices that cause
clogging of the exhaust attached on the exhaust port side in such a
way that they disturb the gas flow. Otherwise the inner pressure of
the vacuum pump may increase and cause a rupture of the casing
and the oil level gauge, resulting in oil leakage and an overload of
the electric motor.
(3) During the operation of this product, the vacuum pump body needs
to be cooled at all times by supplying a specified amount of flowing
water. Install a flow meter that can visually recognize the flow (such
as a flow sight) to check that cooling water flows.
(1) Do not use in a hazardous area (where a hazardous atmosphere may
occur by explosive gas). Otherwise injury or fire may occur.
(2) Do not put your fingers or any objects in the opening of the motor.
Otherwise an electric shock, injury, fire, etc. may occur.
(3) Never place any flammable object in the area within 1m from the
motor or the vacuum pump. Otherwise fire may occur.
(4) Do not place walls and obstacles within 0.3m from the ventilator of
the motor (from the ends of the electric motor). Otherwise you may
get burned or fire may occur.
