2. Notes concerning safety
1) Notes on mounting, removal and installation of product
! DANGER : When you carry the pump, please do not lift the pump up by hands.
Please make sure to use hanging bolt of motor and hang the pump up
by whist, etc..
While you hang and carry the product (the product is being hung),
please do not approach it.

HMP-1817E 6 (4/18)
! WARNING : When using hanging bolts, please use them after you check they are
firmly tightened. After installation of product to the machine, please
do not hang up the whole machine by hanging bolts of motor.
It may result in damage to hanging bolts, injury due to overturn, and
damage of the machine.
! WARNING : Please do not lift up only the pump sides and do not subject it to
impact. It may cause trouble.
! WARNING : Personnel having expertise must mount, remove and install the
product.
! WARNING : Before mounting, removal and installation of the product, please make
sure to turn the power OFF and take action to remove the remaining
pressure in the circuit. After operation, since Coolant Pump, motor
and coolant may be very hot, please take that action after you check
an appropriate temperature (30 40 ) is achieved.
! WARNING : Please do not put flammable objects around the motor. It may cause
a risk of fire.
! WARNING : Please do not put objects which disturb free air draft around the
motor.
It will disturb the cooling and it may cause a risk of explosion, fire or
scald due to abnormal heating.
! CAUTION : Please do not get on, beat or apply a force to the product.
It may cause an human injury and/or damage to product.
2) During operation
! WARNING : Please use product within the range of specified operating conditions
such as ambient temperature, temperature of coolant, etc..
If you use beyond this range, it may cause malfunction, damage to
product and fire.
! WARNING : In case of power failure, make sure to stop the operation immediately.
In case of sudden recovery, the pump and the motor may begin to
work and it may cause human injury.
! WARNING : In case of abnormal condition, make sure to stop the operation
immediately.
It may cause a risk of electrical shock, human injury and fire.
! CAUTION : Since the pump and the motor becomes very hot during operation,
please do not touch them by bare hands.
3) Maintenance
! CAUTION : Please do not disassemble or reconstruct the product without our
approval in writing. If the product is disassembled or reconstructed
without our approval, since it is beyond the scope of our warranty,
we shall not have no responsibility to such disassembly or
reconstruction.

2) Suction pressure of pump
Please set the suction pressure of pump to 0.03 +0.03MPa (-0.3 +0.3kgf/cm2).
3) Suction filter
a) Please make sure to install suction filter to pump suction side.
b) For mesh size, please choose the range of 60 150 meshes according to installation
environment and operating conditions of the unit.
c) For the capacity of filter, please select enough size in consideration of clogging of filter .
4) Suction and Delivery circuit
a) Pump can be damaged caused by air suction or coolant bubble, so please make sure to install
that the pump suction port would be soaked into the coolant at all time.
b) When you install the piping on the suction port, please adjust the height to prevent that
pump draw the sludge stagnating on the bottom of the tank in.
c) In the case that the pipe connected to the delivery port is the steel, it may cause a risk or unit
oscillation, noise increasing and external load for pump, so we recommend to use a rubber
hose.
d) When you need to install the piping, please make sure to clean or neutralize acid in the pipe
before installation.
5) Wiring
! WARNING : Please check the voltage and frequency written in nameplate are
consistent with those you supply.
It may cause a risk of burn or fire.
! WARNING : Please connect the power cable and lead wire of motor according to
connection diagram in terminal box or this manual.
Otherwise, it may cause a risk of electric shock and/or fire.
! WARNING : Do not bend, pull, or pinch the power cable or lead wire of motor
forcibly.
It may cause a risk of electrical shock.
! WARNING : Wiring must be conducted by personnel having expertise.
It may cause a risk of burn or fire.
! WARNING : When measuring insulation resistance, do not touch the terminals.
It may cause a risk of electrical shock.
! WARNING : Please note motor is not provided with protection device.
Please make sure to provide overload protection device.
We recommend you also provide protection device other than for
overload(earth leakage breaker etc.).
! WARNING : Make sure to ground the earth terminal.
Otherwise, it may cause a risk of electrical shock.

HMP-1817E 6 (7/18)
a) Power cable
If the wiring distance is long, because voltage drop becomes high, make sure to use the wire
of appropriate diameter.
Please wire so that the cable is not damaged at cable inlet during operation.
b) Connection of lead wires
For connection between the power cable and lead wires 2
Fig. 2 Connecting diagram
! CAUTION 1. Please do not short-circuit between wires.
2. In case of Y - D start connection, please remove the short bar.
c) Grounding
You can find earth terminal provided inside the terminal box, then make sure to ground it .
d) Procedure of wiring
Remove the terminal box cover.
Mount the crimp-type terminal lug to power cable and clamp it.
After connection, make sure to mount the terminal box cover in place again.

HMP-1817E 6 (8/18)
6) Outlet Pressure
a) Maximum working pressure varies according to combination of pump and motor. Please
ing maximum
working pressure and 100% of motor load. ( You can use the pump at the condition
exceeding 100% of motor load according to working condition. Please contact us.)
b) Surge pressure
When you turn the solenoid valve ON and OFF, surge pressure occurs on pressure line
and it will have a bad influence to the pump or other equipment. Give your
consideration to design of circuit to avoid surge pressure possibly.

HMP-1817E 6 (10/18)
4. Notes on operation
1) Cleaning inside the tank
Please clean the inside of tank before putting coolant into the tank.
We recommend a regular implement of a tank cleaning for damage prevention of the unit.
2) Putting coolant
a) Please put clean coolant sufficiently.
b) If putting coolant by electrical pump, etc., the coolant may foam.
In this case, operate the pump after foam fade outs.
3) Confirmation of rotating direction
! CAUTION : If operating with reverse rotation, pump function may be impaired.
Please confirm the rotating direction by that of motor fan. The correct rotating direction of
motor fan is clockwise.
When checking the rotation, make sure to operate the motor with no inching. Make sure that
operating time of motor during inching operation is 0.5 1 second.
4) Start the operation of pump
! CAUTION : Please avoid on-load start. On-load start may cause the damage
inside the pump.
! CAUTION : Please avoid to operate in the condition of no coolant in the pump.
it may cause the damage inside the pump.
Before the start of the pump, air in the pump must be released.
For the first operation of the unit or operation after replacement of coolant or cleaning of suction
filter, please release the air as follows and start the continuous operation.
Start the pump by inching
a) Check the tank is filled with coolant
b) Operate the motor with no load for 5 10 times intermittently. Make sure that
operating time of motor during intermittent operation is 0.5 1 second.
c) When you repeat inching, noise of suction of air will fade out gradually. After the
noise fade outs, start the continuous operation. If noise of suction of air does not
fade out,there may be the suction port is not immerse in coolant, therefore please
increase quantity of infusion of coolant.

HMP-1817E 6 (11/18)
5) Trial operation
After the start of pump, start the trial operation paying your attention to the following.
a) When you increase the pressure, please be careful of operation noise of pump.
Check there is no noise of air mixture and increase the pressure gradually.
b) If noise of air mixture does not fade out, there may be foams of coolant has not
disappeared sufficiently.
Please operate again after the foam disappears.
5. Maintenance procedure
Main check items, interval and crit
1) In case of a suction filter is installed in the circuit (Cleaning)
If you feel operating noise has changed from that when installed, please check the suction
filter.
The status of filter clogging varies due to primary filtration of the chip and installation
environment, etc.. In general, you should check the filter once per 1 3 months.
2) Control of coolant
When using coolant for long time, it may rot or sludge may grow in the tank.
Please make sure to renew the coolant at regular interval.
