1. PRECAUTION BEFORE USING THE PUMP
1. Connect the earth wire before use.
This enable you to prevent an accident caused by electric shock when the electric insulation is not in order.
For your safety from the danger of electric shock, please be careful not to get power plug stained with water.
2. CAUTION IN CONNECTING THE EARTH WIRE
Connect the earth wire after turning off the electric power.
Never connect with gas pipes, other wire it can be the cause of explosion.
2 .Avoid operating under the condition of dry running and delivering no water.
For it will shorten the service life of pump and also cause the trouble of motor.
3. Never wrap the motor or the pump head in a blanket or a cloth for preventing freezing in the cold weather.
4. Avoid using the pump under the condition of ambient temperature over 40 °C and below 0 °C , and also
with hot water over 40
°C
.
For it will shorten the service life of pump.
5. Be careful not to use the pump with other liquids except for water.
When this used for solvent such as benzol, acid, in flammable liquids such as gasoline and highviscous
liquid, there is a risk of the fire and it will cause the trouble of the pump and also shorten the service life of it.
6. Avoid using the pump under the condition exposed to the direct rays or rain because it will be the reason
of shortening the service life of the pump and also of the danger of electric shock.
7. When this pump is set up in the well, which is easy to suck in sand, above all, sand filter is needed.
For it will prevent the defacement of the impeller in the pump head for a short time, the decline of pressure
and the decrease of pumping water.
8. The permitted voltage of this pump is 10% of the rated voltage. Otherwise it will be the reason of shorte-
ning the service life of the pump.
9. Never operation the pump without priming waters, for it will damage the mechanical-seal and the impeller
and shorten the service life of the pump.
• Before setting the power on, confirm no abnormality by manual operation (exam by driver) of the truly ope-
rating act 2-3 times in checking of dust or sand is put into the pump and also adhesion of impeller or mecha-
nical-seal.
3. WHEN THE PUMP IS REUSED AFTER A LONG TIME
There is possibility for the motor not to be operation in the condition of switching on the electric power,
because of the sticking and solidification of the dirt and filth in the water of the pump head.
In that case, turn off the electric power, and then turn the shaft in the back of the motor a few times with
driver or something like that. After that, you can operation the pump as usual.

4. CHECKING POINTS BEFORE INSTALLATION
- Install the pump just over the well as possible as you can.
- But when the pump must be installed away from the well because of the circumstances, the maximum
distance of the pipe from the well to the pump is limited according to the suction lift.
- Decide the suction lift considering the dry seas.
5. GUIDE FOR INSTALLATION
- Concrete the foundation with cement that the pump may not lean or slant even after many years.
- Select the place where the pump can be conveniently checked or repaired after installation.
- Install the stop valve on the dishrag side of the pump and it will be very convenient for checking and repai-
ring the pump.
- Minimise the number of the elbows to prevent the water leaking in the piping or to lessen the resistance of
water.
6. HOW TO OPERATION THE PUMP
- This pump is not self-priming type, should be installed foot-valve to the bottom of suction pipe.
- Measure the depth from the ground surface to that of the well. The suction head is standardized at 8 m
(max. 9m).
- Be sure to use pipe of standard diameter for normal.
7. CONNECTION METHODS FROM POWER
- When the pump is sending out from the manufacture, it is set for 110V/60Hz.
- Check the voltage of the electric power before operating the pump.
- Warranty does not include accidents due to incorrect installation. See your electrician for advice. It is recom-
mended to have a protected motor circuit breaker near the pump. It will cut power in case of surcharge, bloc-
king or missed.
- Take terminal box cover off.
2. Drive the 3 wires electric cable through opening (minimum section 1,5 mm ).
- Connect 2 wires to terminals N and L. Connect earth wire (green/yellow) to terminal located under terminal
block, marked with symbol. On figure.
- Put cover back.

8. HOW TO START THE PUMP
Since this pump has no self-priming system, at the start of operation, make priming by the following
sequence:
- Be pulled out with the water.
- Before the power switch on, the water cock of the discharge side should be opened.
- After the power switch on, start priming procedure immediately.
- When the priming is not successful, air may be remained in the suction pipe. Then, to remove air in the
suction pipe, pour water and power on and off repeatedly.
- Because the pump has no switch, use power switch on the wall or plug in and out from the receptacle.
