Be sure to thoroughly read and understand the SAFETY PRECAUTIONS given in this section before using
the equipment in order to operate the equipment correctly.
The precautionary measures described in this section are intended to prevent danger or damage to you or
to others. The contents of this manual that could possibly be performed improperly are classified into two
categories:
WARNING, and
CAUTION. The categories indicate the extent of possible damage
or the urgency of the precaution. Note however, that what is included under
CAUTION may at times
lead to a more serious problem. In either case, the categories pertain to safety-related items, and as such,
must be observed carefully.
WARNING : Operating the equipment improperly by failing to observe this precaution may possibly
lead to death or injury to humans.
CAUTION : Operating the equipment improperly by failing to observe this precaution may possibly
● NOTE
cause injury to humans and other physical damage.
: Gives information that does not fall in the WARNING or CAUTION categories.
● Explanation of Symbols:
：The mark indicates a WARNING or CAUTION item. The symbol inside the mark describes the
precaution in more detail ("electrical shock", in the case of the example on the left).
：The mark indicates a prohibited action. The symbol inside the mark, or a notation in the vicinity of
the mark describes the precaution in more detail ("disassembly prohibited", in the case of the
example on the left).
：The mark indicates an action that must be taken, or instructs how to perform a task. The symbol
inside the mark describes the precaution in more detail ("provide ground work", in the case of the
example on the left).

CAUTION
Do not operate the product under any conditions other than those for which it is specified. Failure to observe the precaution can lead to electrical leakage, electrical
shock, fire, water overflow or other problems.
35(&$87,216'85,1*75$163257$1',167$//$7,21
When transporting the product,
pay close attention to its center of
gravity and mass. UIse an appropriate lifting equipment to lift the
unit. Improper lifting may result
in the fall of the product which
could cause damage of the
product or human injury.
WARNING
Install the product properly in
accordance with this instruction
manual. Improper installation
may result in electrical leakage, electrical shock, fire,
water leakage, or 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
equipment can lead to electrical
leakage, fire, or explosion in the
worst case.
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.
Frequency
Voltage
CAUTION
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 electrical shock.
Attach a hose securely to the hose
coupling. Imperfect connection
of hose could cause water
leakage which may result in the
damage of neaby walls, floors,
and other equipment.
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, shortcircuit, electrical shock, or fire.
Do not use the cabtyre cable if it is
damaged. 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.
Use the handle when installing or
carrying the pump. Never use the
cable to carry or to suspend. Doing
so may damage the cable which
could cause electrical leakage,
short circuit, or fire.
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.
Allow the pump to suck as few
foreign object as possible. If there
is a risk that the pump could be
buried under the sediment, place it
on a solid base like concrete
block. Failure to do so may
result in breakdown of the
pump and could cause electrical leakage or short circuit.
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.

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.
Never start the pump while it is
suspended, as the unit may jerk
and could lead to injury.
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.
Do not operate the product under
any voltage other than described
on the nameplate with the voltage
variation limit within ±10%. If it is
operated with a generator, it is
strongly suggested not to operate
other equipment with the same
generator. Failure to observe

CAUTION
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 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.

cable in water.
Extension cable
If the cabtyre cable must be
extended, use an extension
cable with the same or larger
core size as that of the cable
that is provided with the pump.
To prevent water from
entering inside the

securely mold the cable
connection portion.
To avoid damaging the
cable, arrange the cable
run so that the cable is not
