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 pump (available on the market).
Imperfect wiring or improper protective
equipment can lead to electrical leak-
age, fire, or explosion in the worst case.
Install the product properly in
accordance with this operation
manual. Improper installation
may result in electrical leakage,
electrical shock, fire, or injury.
When transporting the product,
pay close attention to its center
of gravity and mass. Use an
appropriate lifting equipment to
lift the unit. Improper lifting may result in
the product damage, injury, or death.
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.
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 electrical 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.
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.
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 waist.
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.
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.
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.
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 touch the product with bare
hands during or 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 product in a liquid
other than water. Use in oil, salt
water or organic solvents will
damage it, which may lead to
electrical leakage or electrical
shock.
Do not run the product dry or
operate it with its valve (sluice or
gate valve) closed, as doing so
will damage the product, which
may lead to electrical leakage or
electrical shock.
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.

Failure to observe this caution
could cause it to malfunction or
to operate abnormally, which
may lead to electrical leakage or
electrical shock.
Do not use the product in hot or
warm liquid over 40°C, as doing so
will damage the product, which
may lead to electrical leakage or
electrical shock.
When the product will not be used
for an extended period, be sure to
turn off the power supply (earth
leakage circuit breaker, etc.).
Deterioration of the insulation
may lead to electrical leakage,
electrical shock, or fire.
CAUTION
WARNING
Absolutely turn off the power
supply or disconnect the plug
before starting maintenance or
inspection. Do not work with wet
hands. Failure to observe these
cautions may lead to electrical shock or
injury.
After reassembly, always perform a test operation before resuming use of the product.
Improper assembly can result in electrical leakage, electrical shock, or fire.
In case any abnormality
(excessive vibration, unusual
noise or odor) is found in the
operation, turn the power off
immediately and consult with the
dealer where it was purchased or Tsurumi
representative. Continuing to operate the
product under abnormal conditions may
result in electrical shock or fire.
