Preparation for Installation
Single-phase power supply:
Use a megger to measure the resistance between the
tip of the cabtyre cable plug and the ground terminal to
verify the insulation resistance of the motor.
(This diagram shows a 2-pin plug type.)
The insulation resistance reference value of 20M minimum is based on a new or repaired pump. For refer-
ence values of a pump that has already been put into operation, refer to "7. Maintenance and Inspection" of
this manual.
Note:
Three-phase power supply:
Use a megger to measure the resistance between each
core of the cabtyre cable and the (green) ground wire to
verify the insulation resistance of the motor.
Beware that the power plug
varies by country or region.
CAUTION
Insulation resistance reference value = 20M Ω minimum
Precautions During Installation
When installing the pump, be mindful of the pump's center of gravity and
weight. If the pump is not suspended properly, the pump may fall and break,
which may lead to injury.
When installing or moving the pump, never suspend the pump by the cabtyre
cable. Doing so will damage the cable, which may cause a current leakage,
electrical shock, or re.
Refer to the installation examples illustrated below and pay attention to the points described below to install
the pump.
During piping work if the welding sparks, paint, or concrete come in contact
with the pump, they could cause the pump to malfunction, which may lead to
current leakage or electrical shock.
WARNING
CAUTION
CAUTION
Free Standing Specication Guide-Rail Specication
(1) When transporting or installing the pump, do not kink the cabtyre cable or use it in place of a rope.
(2) With the cabtyre cable lifted slightly, secure it to the hook (a hook must be prepared in advance by
placing it on the frame of a manhole or the like).
Do not operate the pump with the cabtyre cable dangling. Failure to observe
this precaution may cause the cabtyre cable to become wrapped around the
impeller, which could cut the cable, break the impeller, or cause ooding,
which may lead to current leakage or electrical shock.
(3) Install the pump on a horizontal and rigid surface such as concrete, in an area that is free from
turbulence and does not cause the pump to take air in.
(4) The area near the inlet of a water tank is susceptible to turbulence or allows the pump to take air in;
therefore, place the pump and the oat switch away from the inlet or install a bafe plate.

Motor Protector
The pump is equipped with an internal motor protector.
1. Circle Thermal Protector:
If a current overload or overheating occurs under the symptoms given below, the motor will stop
automatically to protect the motor regardless of the water level at the time of operation.
In this type of motor protector, the motor will automatically restart after cooling down. If the motor is
stopped by protector tripping, turn off the power supply rst, and disconnect the cables from the power
terminals. After this, make sure to eliminate the cause of the problem, such as the following:
• Extreme uctuation of power supply voltage
• Pump operated under overload condition
• Pump operated at open phase or binding condition
2. Miniature Protector
Embedded in the winding of the motor, the miniature protector's bimetal trips if the motor winding
overheats for any reason. Upon receiving this signal, the current to the motor can be cut off through the
use of an external starting panel or installing a dedicated electrical circuit in the control panel. When the
motor's temperature decreases, the bimetal reverts automatically, but the restarting must be effected at
the external starting panel or the control panel.
Tsurumi's miniature protector adopts a "normally closed" contact system in which the circuit opens when the
protector trips (the circuit remains closed when normal). Also, make sure to install an external starting panel
or a motor breaker or thermal relay in the control panel to protect the motor from overload. The motor can be
protected from overload, open phase, or reverse phase condition by installing a 3E relay.
Make sure to eliminate the cause of the problem if the motor protector has tripped. Do not operate the pump
at unusually low head, or with the impeller clogged with debris. Doing so will not only prevent the pump from
attaining its full potential, but may also generate abnormal noise and vibration and damage the pump.

Prior to Operation
(1) Once again, check the nameplate of the pump to verify that its voltage and frequency are correct.
Improper voltage and frequency of the power supply will prevent the pump
from attaining its full potential, and may also damage the pump.
Verify the specs on the pump's nameplate.
(2) Check the wiring, power supply voltage, the capacity of the ground leakage circuit breaker, and the
insulation resistance of the motor.
Insulation resistance reference value = 20MΩ minimum
The insulation resistance reference value of 20Mminimum is based on a new or repaired pump. For refer-
ence values of a pump that has already been put into operation, refer to "Maintenance and Inspection".
(3) Adjust the setting of the thermal relay (i.e. 3E relay) to the pump's rated current.
Verify the rated current on the pump's nameplate.
CAUTION
Note:
Note:
Note:
Trial Operation
Never start the pump while it is suspended, as the pump may jerk and cause
a serious accident involving injury.
(1) Operate the pump for a short time (1 to 2 seconds) and verify the direction of the rotation of the impeller.
Observe the pump unit from above, and if its recoil is in the counterclockwise direction, the direction of
its rotation is correct.
Make sure to check the pump's direction of rotation with the pump exposed
to the atmosphere. Operating the pump in reverse while it is submerged in
water will damage the pump, which may lead to current leakage and electrical
shock.
(2) To reverse the rotation, the following countermeasures must be taken.
WARNING
CAUTION
Before changing the connections for reverse
rotation, make sure that the power supply
(i.e. circuit breaker) is properly disconnected
and that the impeller has stopped
completely. Failure to observe this may lead
to electrical shock, short, or injury.
COUNTERMEASURE

COUNTERMEASURE
If the power supply voltage deviates from the variation value, the cause of the deviation may be the capacity of
the power supply or the extension cable that is used. Refer to section "5. Electrical Wiring" to operate the pump
in the correct manner.
COUNTERMEASURE
Because an overload condition may be present at the pump motor if the operating current exceeds the rated
current, follow the instructions in section "4. Installation" to operate the pump in the correct manner.
(3) Connect the pump to the pipe and submerge it in water.
(4) Operate the pump for a short time (3 to 10 minutes) and perform the following checks:
Using an AC ammeter (clamp), measure the operating current at the phases U, V,
and W that are connected to the terminal board.
In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales ofce in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or re.
(5) Proceed with the normal operation if no abnormal conditions are found during the trial operation.
CAUTION
Operation
The pump unit may be extremely hot during operation. To prevent burns, do
not touch the pump unit with bare hands during or after the operation.
Pay attention to the water level during the pump operation. The pump will become damaged if it is allowed to
operate dry.
Due to an overload operation or a pump malfunction, if the motor protector trips to stop the pump, make sure
to eliminate the cause of the problem before restarting.
To operate a submersible pump (including automatic operation), set the water level so that the pump will
operate at approximately the following rate: less than 5-6 times per hour on models with output of 3.7kW or
less, and 3-4 times per hour on models with output of 5.5kW or more.
A large amount of amperage ows when a submersible pump is started, causing the temperature of its wind-
ings to rise rapidly. Beware that a frequent stop-and-go operation of the pump will accelerate the deteriora-
tion of the insulation of the motor windings and thus affect the use life of the motor.
WARNING
Note:
Operating Water Level
Do not operate the pump at the lowest water level longer than 30 minutes,
as it could damage the pump, causing current leakage and electrical shock.
For details on the lowest water level, refer to the dimension drawing, which is
provided separately.

6-2 Automatic Operation
Trial Operation
Equipped with oats to detect the water level and an internal control circuit, the automatic type (CA) pump
can perform an automatic drainage operation alone by merely connecting its cable to a power supply.
Connect the power and perform a trial operation as follows:
Allow the pump to operate a minimum of 2 seconds for each trial operation. The trial operation must be com-
pleted within 1 minute.
Note:
In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales ofce in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or re.
CAUTION
6-3 Automatic Alternating Operation
Trial Operation
The (CW) automatic alternating type pump is used in conjunction with the (CA) automatic type. Equipped
with oats to detect the water level and an internal control circuit, it can perform an automatic alternating
drainage operation by merely connecting its cable to a power supply.
Connect the power and perform a trial operation as follows:
(1) Direct all the oats downward.
(2) First raise the (red) stop oat, then the (yellow) start oat.
This will cause the pump to start.
(3) Next, return the (yellow) start oat, and then the (red) stop
oat to their original positions. This will cause the pump to
stop.
(4) Perform steps (2) and (3) consecutively two or more times to
verify the operation.
It takes approximately 1 second for the pump to start after the oat is moved. Allow the pump to operate a
minimum of 2 seconds for each trial operation. The trial operation must be completed within 1 minute.
Note:
In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales ofce in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or re.
CAUTION
(7) Next, return the (green) parallel operation oat, then the (yellow) alternating start oat, and then the (red)
stop oat to their original positions. This will cause the pump to stop.
(8) Perform steps (6) and (7) consecutively two or more times to verify the operation.
(1) Direct all the oats downward.
(2) First raise the (red) stop oat, then the (yellow) alternating start oat.
(3) Next, return the (yellow) alternating start oat, and then the (red)
stop oat to their original positions. This will cause the pump to stop.
(4) Perform steps (2) and (3) consecutively three or more times to verify
the operation. The pump will start and stop every other time.
(5) Again, direct all the oats downward.
(6) After performing the trial operation of pump by the step (2) and (3).
Raise the (red) stop oat, then the (yellow) alternating start oat, and
the (green) parallel operation oat. This will cause the pump to start.

Regular maintenance and inspection are indispensable to maintaining the pump's performance. If the
pump behaves differently from its normal operating condition, refer to section "9. Troubleshooting" and
take appropriate measures at an early stage. We also recommend that you have a spare pump on hand
for an emergency.
Prior to Inspection
Make sure that the power supply (i.e. circuit breaker) is disconnected and
disconnect the cabtyre cable from the power outlet or remove it from the
terminal board. Failure to do so may cause electrical shock or unintended
starting of the pump, which may lead to serious accidents.
(1) Washing the Pump
Remove any debris attached to the pump's outer surface, and wash the pump with tap water. Pay
particular attention to the impeller area, and completely remove any debris from the impeller.
(2) Inspecting the Pump Exterior
Verify that there is no damage, and that the bolts and nuts have not loosened.
If the pump must be disassembled for repair due to damage or loose bolts or nuts, contact the dealer where
it was purchased, or the Tsurumi sales ofce in your area.
WARNING
Note:
Daily and Periodic Inspection
Refer to section "Oil Inspection and Change Procedures" below for further detail.
Note:
In case the pumping liquid contains oil, paint, or slurry, it may cause the swelling of cable jacket or abrasion
of the mechanical seal's sealing face, which will result in the pump fault, it is strongly recommended to
inspect earlier.

Storage
If the pump will not be operated for a long period of time, pull the pump up, wash the pump, allow it to dry,
and store it indoors.
For reinstallation, be sure to perform a trial operation before putting the pump into operation.
If the pump remains immersed in water, operate it on a regular basis (i.e. once a week).
Note:
Oil Inspection and Changing Procedures
Inspecting Oil
Remove the oil plug and take out a small amount of oil.
The oil can be extracted easily by tilting the pump so that
the oil ller plug faces downward. If the oil appears milky
or intermixed with water, a likely cause is a defective shaft
sealing device (i.e. mechanical seal), which requires that
the pump be disassembled and repaired.
Changing Oil
Remove the oil plug and drain the oil completely. Pour a
specied volume of oil into the oil ller inlet.
The drained oil must be disposed of properly to prevent it
from being released into the sewer or rivers. The packing or
the O-ring for the oil plug must be replaced with a new part
at each oil inspection and change.

Observe the precautions given below and reassemble the unit in the reverse order of disassembly.
After completing the reassembly, make sure to ll the pump with the specied amount of oil. The packings
must be replaced with a new part. If any part is worn or damaged, make sure to replace it with a new part.
After reinstalling the impeller or the suction cover, check that the impeller rotates smoothly and that there is
no interference between the pump casing and the suction cover.
Note:
(1) Removing the stand and suction cover
Remove the hex bolts, and spring washers; then, remove the stand and suction cover and the packing
from the pump casing.
(2) Removing the impeller
Using a box wrench, remove the impeller nut and spring washer; then, remove the impeller and the
impeller adjusting washer from the shaft.
This section explains the disassembly and reassembly processes that are involved up to the replacement
of the impeller itself. Operations involving the disassembly and reassembly of the sealing portion (i.e.
mechanical seal) and of the motor require a specialized facility including vacuum and electrical test
equipment. For these operations, contact the dealer where this equipment was purchased, or the Tsurumi
sales ofce in your area.
Prior to Disassembly and Reassembly
Before disassembling and reassembling the pump, be sure that the power
supply (i.e. circuit breaker) is disconnected, and remove the cabtyre cable
from the outlet or the terminal board. Do not connect or disconnect the
power plug with a wet hand, in order to prevent electrical shock. Do not
perform an activation test (to check the rotation of the impeller) during
disassembly and reassembly. Failure to observe this precaution could
lead to a serious accident, including injury.
