example on the left).
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
When transporting the product,
pay close attention to its center of
gravity and mass. Use an appro-
priate 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.
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 leak-
age, fire, or explosion in the worst case.
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.

Do not operate the product under any conditions other than those for which it is speci-
fied.Failure to observe the precaution can lead to electrical leakage, electrical
shock, fire, water overflow or other problems.

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.
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.
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.
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.
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.
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 electri-
cal leakage or short circuit.
Do not use the cabtyre cable if it is
damaged. Connect every conduc-
tor of the cabtyre cable securely to
the terminals. Failure to observe
this can lead to electrical shock,
short-circuit, or fire.
Attach a hose securely to the hose
coupling. Imperfect connection of
hose could cause water leakage
which may result in the damage
of 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.
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 genera-
tor, it is strongly suggested not to
operate other equipment with the
same generator. Failure to observe
this caution may cause malfunc-
tion and breakdown of the prod-
uct, which may lead to electrical
leakage or electrical shock.
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.
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 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.

In case of power outage, turn off the power supply. The product will resume opera-
tion when the power is restored, which presents serious danger to people in the
vicinity.
WARNING

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 prod-
uct. Improper assembly can result in electrical leakage, electrical shock, fire, or
water leakage.
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 representa-
tive. Continuing to operate the
product under abnormal condi-
tions may result in electrical
shock, fire, or water leakage.
Do not disassemble or repair any
parts other than those designated
in the operation manual. If repairs
are necessary in any other than
the designated parts, consult with
the dealer where it was

Electrode level sensor will submerge and the
pump will operate by the current.
When the water level drops and detaches
the electrode from the water surface, a timer
will start. Pump keeps draining.
The operation time with the timer will be
approx. 1 minute.
After 1 minute, the pump will stop.
* If the water is drained within 1 minute, the
pump continues to run in snore mode until
the set time comes.
When the water level rises and the water
surface touches to the electrode again for
more than one (1) second, pump will restart.
(Detection Time : more than one (1) second)
(Released the Electrode The timer is on)
(Detection Time : more than one (1) second)
* If the water surface touches to the electrode
for more than one (1) second within 1 minute,
the pump operates continuously even though
the timer is on.

Measuring the operating current
Measure insulation resistance
Note: If the insulation resistance has become notably lower than the previous inspection, an
inspection of the motor will be necessary.
Note: Consult with your nearest dealer or Tsurumi representative regarding overhauls.
Note: Specialized know-how is required for inspecting and replacing the mechanical seal.
Consult with your nearest dealer or Tsurumi representative.
Note: See below for details of oil inspection and oil change.
Overhaul
Change oil
Change mechanical seal
Change the oil every 12 months or after 6,000 hours of use, whichever comes first.
Oil inspection Check the oil every six months or after 3,000 hours of use, whichever comes first.
Pump inspection A noticeable drop in performance may indicate wear in the impeller etc., or else
clogging of the strainer stand, etc. Remove the clogged debris,and replace any
worn parts.
Designated oil : Turbine oil VG32
Power supply voltage tolerance
= within ±5% of the rated voltage
Measuring the power voltage
To be below the rated current
Reference insulation resistance = 1MΩor greater
This should be carried out even if there are no problems with the pump.
The frequency depends on how continuously the pump is in use.
Inspection of lifting wire rope or chain
Replace if damage, corrosion, or wear has occurred to the wire rope or the chain.
Remove if foreign object is attaching to it.
Inspecting the electrode Clean the electrode periodically with an abrasive paper or the like.
