Installation
(1) Do not use the pump in an explosive atmosphere. Such use may result in injury and fire.
(2) Ensure that there are no inflammable materials such as solvents in the vicinity when
using the pump.
(3) Ensure that the pump is freely ventilated to prevent overheating, which may result in fire
or burns. Open the distance from the shield to the ventilation entrance part for the fan by
3.5cm or more when you set it up.
Power Supply
(4) Always check the pump and install wiring with the power cord disconnected. Working
with power connected may result in electric shock, or the pump starting unexpectedly.
(5) Ensure that wiring is installed by persons qualified in accordance with regulations for
wiring (e.g. technical standards for electrical equipment, requirements for internal wiring).
Incorrect wiring with may result in fire.
(6) Ensure that lead wiring is properly connected and insulated with insulation tape (or an
insulating cap).
(7) Always ensure that the pump is correctly earthed. A dedicated earth leakage breaker is
recommended. Failure to earth the pump correctly may result in electric shock if a fault or
earth leakage occurs.
(8) Use the pump only at the rated voltage. Use at other than the rated voltage will interfere
with operation of the overload protection device, and this may result in the motor burning
out, or fire.
(9) Do not damage, modify, and pull the power cord, or place objects on it. Damage to the
cord may result in electric shock or fire.
(10) Always fully insert the power cord into the socket. Partial insertion may result in electric
shock.
(11) Remove the cord from the socket while holding the plug. Failure to do so may result in
electric shock.
(12) Touching the power cord with wet hands may result in electric shock.
(13) Touching electrical wiring etc while inserting the power plug may result in electric shock.
(14) The electric motor fitted to this pump incorporates a thermal protector, however it is not
guaranteed to be open when it eventually fails at some time. For safety reasons
therefore, it is necessary to fit an overload (over current), protection device and an earth
leakage breaker.
Operation
(15) This pump is not designed to be explosion-proof. When using the pump, ensure that
there are no inflammable materials such as solvents, or explosive gases, in the vicinity.
Use under such conditions may result in injury or fire.
(16) Inserting fingers or objects into the motor inlet may result in electric shock, injury, or fire.
(17) Operating the pump with the discharge outlet blocked, or with a device which prevents
passage of gas to the discharge outlet, may result in rupture of the pump. The internal
pressure of the pump rises and the pump body may rupture and the motor become
overloaded.
This pump is not designed to be pressure-resistant. The internal pressure of the pump is
limited to 0.03 MPa (gauge pressure).
Maintenance and Repair
(18) The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
(19) To prevent ingestion of microscopic particles resulting from wear of components, use a
dust mask and gloves during repair work.
