Warning
When using for dangerous liquid or in atmospheres
When using the pump for dangerous liquid or in potentially explosive atmospheres (only explosion- proof
type), adhere to facility standards determined by law and check no liquid leak daily. If the pump is
operated under abnormal conditions such as liquid leak, it leads to explosion, fire or personal injuries.
Follow the manufacturers
’ instructions about handling the liquid.
Banning the use of damaged or modified pumps
If using the damaged of modified pump, it may cause personal injuries, electric shock or the pump
damage. They are not covered by warranty.
Caution in transporting and lifting pumps
Use the hoist bolt when lifting a pump. If it does not own the hoist, use a belt sling and lift the pump with
careful attention to the weight balance. Perform it by qualified personnel with the strong enough sling. The
weight of the lightest pump is approx. 23kg at least. Do not carry a pump by hand as much as possible,
because it may cause an accident.
Banning the operation with the power on
Do not check or disassemble a pump or motor while the power on. It leads to personal injuries from
electric shock or getting caught in the rotor. Take the multiple safety precaution such as the switch for
main power supply, the operation switch, and the hand switch for the pump.
Connection of an earth wire
Using the pump without connecting an earth wire may cause electric shock. Perform the connection by a
qualified person according to the electric
facility’s technical standards and interior wiring regulations.
Protection of the power supply cord.
If stretching, pinching or damaging the power supply cords or motor lead wires, it causes fire or electric
shock for the damaged cable. Install the cover of the terminal box in its proper position after wiring.
Ground Fault Interrupter (GFI)
If using a pump without a ground fault interrupter device, it may cause electric shock. Prevent the
electric accidents and the pump damages applying circuit breakers, over-current protection devices
and/or other protective devices.
Caution in removing a pump
When removing a pump from pipes, close the suction and discharge pipe valves and check no liquid leak.
If direct contact with liquid, it may cause injury. Always wear protective gear when performing operations.
