Prior to operation:
a. Be sure to provide an adequate grounding and install the leakage breaker without fail. It is
important that pump should be properly grounded and provided with leakage breaker to
prevent the users from serious electric shock injury.
b. Make sure if the voltage of the power supply is identical to the one indicated on the
nameplate label) of the pump. Do not plug in to other voltage and phase than the
indication on the nameplate.
c. Do not have a dry-run in the air, it will damage the pump.
d. Do not use the electrical cable to carry the pump. Do not lift or lower the pump by the
cable, please carry with pump handle.
e. Extension of power cable:
When the power cable has to be extended, select the proper cable size within the
allowable extension. If cable is extended too far, a drop in voltage may occur, which will
stop the running of motor and damage the pump.
Do not use the pump in the pond, swimming pool and bath tub where there is any people
in to prevent any possible accident.

Care under operation:
a. When the pump stops suddenly by the motor protection device).
The motor protection device is built in to shut off the circuit automatically and to prevent
the motor from burning out when the motor is overloaded due to the clogging by foreign
particles or plug-in to wrong power source Voltage, Frequency, and etc.). Should the
pump stop suddenly, please check piping, pump itself, connection of electrical cable to
power source, and etc., the motor protector always automatically trips off in a few seconds
if there is any abnormality it gets response. Please resume the operation after clearing the
trouble and leave the pump as it is.

to have a proper notice on following points:
a. If a freezing temperature is predicted, lift up the pump from water and restore it in dry
condition.
b. If pump is left in the water for a long period of time without running, it brings rust and
any possible floating matters accumulated in the pump, which will inevitably shorten the
life of pump. In this case, let the pump run in the clean water and remove floating matters
from the pump inside. Restore it after being dried.
4. Applications:
The most efficient, versatile and cost-effective products you’ll ever use!
a. Water treatment process in sewage treatment yards.
