Use an appropriate lifting equip-
ment to lift the unit. Improper
lifting may result in the fall of
the product which could cause
damage of the product or
human injury.
Electrical wiring should be
performed in accordance with all
applicable regulations in your
country. Absolutely provide a
dedicated earth leakage circuit
breaker and a thermal overload
relay suitable for the product
(available on the market). Imperfect
wiring or improper protective equip-
ment can lead to electrical leakage, fire,
or explosion in the worst case.
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.

CAUTION
Do not scratch, fold, twist, make
alterations, or bundle the cable, or
use it as a lifting device. The cable
may be damaged, which may
cause electrical leakage, short-
circuit, electrical shock, or fire.
Be sure to provide a ground wire
securely. Do not connect the
ground wire to a gas pipe,
water pipe, lightening rod, or
telephone ground wire. Improper
grounding could cause electri-
cal shock.
Do not use the cabtyre cable, power
plug, or power outlet if it is damaged
or it is not closely fitted. Connect
every conductor of the cabtyre cable
securely to the terminals. Failure to
observe this can lead to electrical
shock, short-circuit, or fire.
When the product will be carried by
hand, decide the number of persons
considering the mass of the product.
When lifting up the product, do
not attempt to do it by simply
bowing from the waist. Use the
knees, too, to protect your back.
This pump is neither dust-proof nor
explosion-proof. Do not use it at a
dusty place or at a place where
toxic, corrosive or explosive gas is
present. Use in such places
could cause fire or explosion.
Prevent a metallic object or dust
from sticking to the power plug.
Adhesion of foreign object to the
plug could cause electrical
shock, short-circuit, or fire.
If a hose is used for the discharge
line, take a measure to prevent the
hose from shaking. If the hose
shakes, you may be wet or
injured.
Install the discharge pipe
securely so that no water leakage
may occur. In addition, It is
suggested to provide a stand-by
pump in case of flooding. Failure
to do so may result in damage
to nearby walls, floors, and
other equipment.
CAUTION
WARNING
Never try to operate the pump if
somebody is present in the pump
sump.If an electrical leakage
occurs, it can cause electrical
shock.
When changing power connection is
needed to correct the direction of
rotation, be sure to turn off the
power supply (earth leakage circuit
breaker, etc.), and perform the work
after making sure that the impeller
has stopped completely. Failure to do so
may lead to electrical shock, short-
circuit, or injury.
Never start the pump while it is
suspended, as the unit may jerk
and could lead to injury.
When inspecting the pump, be sure
to turn off the power supply (earth
leakage circuit breaker, etc.) so that
the pump may not start acciden-
tally. Failure to do so may lead to
a serious accident.
Do not operate the product under
any voltage other than described
on the nameplate with the voltage
tolerance limit within ±5%. If it is
operated with a generator, it is
strongly suggested not to operate
other equipment with the same
generator. Failure to observe this caution
may cause malfunction and breakdown
of the product, which may lead to
electrical leakage or electrical shock.
Do not touch the product with bare
hands during or immediate after
the operation, as the product may
become very hot during operation.
Failure to observe this caution
may lead to be burned.
Do not use the pump for oil, sea
water, or strong acid. Use for
these liquid may result in the
damage of the pump.
Do not run the product dry or
operate it with its gate valve
closed, as doing so will damage
the product, which may lead to
electrical leakage or electrical
shock.
