When transporting the product, pay
close attention to its center of
gravity and mass. Use an appropri-
ate lifting equipment to lift the unit.
Improper lifting may result in the
product damage, injury, or death.
Electrical wiring should be
performed in accordance with all
applicable regulations in your
country. Provide a dedicated earth
leakage circuit breaker and a
thermal overload relay for the pump.
Imperfect wiring or neglecting the
installation of proper equipment
will cause electrical leakage, fire,
or explosion at worst.
Use a power outlet that has a sufficient rating and has been exclusively
provided for the pump.
If the power outlet is shared with other equipment,
it can lead to an abnormal heat of the outlet and can cause fire as a
result.
Install the product properly in
accordance with this instruction
manual.
Improper installation
may result in electrical leakage,
electrical shock, fire, water
leakage, or injury.
Provide a secure grounding
dedicated for the product. Never
fail to provide an earth leakage
circuit breaker and a thermal
overload relay in your starter or
control panel (Both available on
the market).
If an electrical
leakage occurs by due to a
product failure, it may cause
electrical shock.
