Fig.4
3PH/50HZ LX pump Full Load AMP Chart
1).Wiring
Wiring should be performed as indicated for the appropriate start system as shown in Fig.4.
2).Cable
a)Never let the end of the cable contact water.
b)If the cable is extended, do not immerse the splice in water.
c)Fasten the cable to the discharge piping with tape or polyvinyl chloride strips.
d)Install the cable so that it will not overheat. Overheating is caused by coiling the cable
and exposing it to direct sunlight.
e)The signal cable on pumps over 5hp consist of four wires P1(red) and P2(white) are the
thermal protection wires. P3(black) and P4(green) are the seal leak detector wires. All
signal wires should be connected to a relay or contactor, as applicable in the pump
controller in order to properly safeguard the pump. The seal leak detector requires a
normally open contact which closes when water is detected in the seal chamber.
3).Grounding
Install and ground an earth cable. (The earth cable is the green wire that is one of the 4 cores
in power cable) Under no circumstances should the green wire be connected to the power
supply.
4).Motor protection
a)Auto-cut (Built-in in 3HP motor)
Auto-cut will be activated when motor is operated in abnormal conditions such as locked
rotor or single phase that result in excess overheating.

(6) Operation
Caution
Do not insert hands, foot etc. into the suction inlet during operating.
Otherwise, pump could cause injuries by the rotating parts.
Do not operate in the air. Otherwise, insulation deteriorates. Then
electric leakage and electric shock could occur.
Do not use this pump when anyone is in the water.
Electric shock could occur during electric leakage.
1.Before starting the pump
a) After completing installation, measure the insulation resistances again as described
in section (5) “Installation”.
b) Check water level
If the pump is operated continuously for an extended period of time in a dry
condition or at the lowest water level, the motor protector will be activated.
The repetition of this condition will shorten pump service life. Do not start the pump
again in such a situation until after the motor has completely cooled.
2.Test operation
a) Turn the operating switch on and off a couple of times to check for normal pump
start.
b) Check the direction of rotation. If discharge volume is low or unusual sounds are
heard when the pump is operating, rotation has been reversed. When this
happens, reverse two of three wires (see Fig.5).
Fig.5
c) After confirming the direction of rotation, open gradually the discharge valve and let
the pump run in continuous operation. Check current, voltage, and discharge
pressure. (Refer section (8) “Troubleshooting”)
When amperage exceed the rated ampere without discharge valve. The plan
should be reviewed.
3.Operation
a) After test operation, pump could be operated immediately.
b) Do not repeat starting and stop frequently.
The number of starting times per hour is shown in the following table.

c) Do not operate a pump in the outside of the specified range.
NOTE
Run the pump at a discharge capacity that is suitable for the equipment.
(Capacity that is too large or small will cause noise and vibration, and
vibration, and also waste power.)
(7) Maintenance
Warning
Disassembly and repair of the pump should be performed by a maintenance
specialist. Otherwise, error by personnel could result in electric shock, and the
pump catching fire or operating abnormally and causing injury.
Always turn the power switch OFF before inspecting or repairing the pump.
Otherwise it could result in the pump starting up suddenly in auto operation,
exposing personnel to danger.
Always turn the power switch OFF if the pump is to be out of use for a long
time.
If the power is left ON and insulation deteriorates, then electric leakage and
electric shock could occur.
Caution
In the insulation resistance under 1MΩ, electric shock could occur. Turn the
power switch OFF as soon as possible. Contact the shop from where you
ordered the pump to perform an inspection and maintenance on the pump.
To prevent an accident if the pump stops running or an abnormality occurs,
immediately turn off the power switch. Contact the shop from where you
ordered the pump to perform an inspection and maintenance on the pump.
Check for abnormality in pressure, discharge capacity, voltage, current, vibration and noise. If
any of these is different from normal, trouble of some kind is probably going to occur and you
should take prompt corrective action. Refer to section (8) “Troubleshooting”for diagnosis and
corrective action.
You are advised to post a Daily Operation Condition Check Sheet to facilitate such checking.
Note
A standard pump performance curves are available from your nearest sales office or
dealer.
1. Daily inspections
a) Check current value and its fluctuation daily. If ammeter fluctuation is great, even though
within the limits of pump rating, foreign matter may be clogging the pump.
b) If the quantity of liquid discharged falls suddenly, foreign matter may be blocking the
suction inlet.
2. Regular inspections
a) Every month
Measure the insulation resistance. If the insulation resistance is 1MΩ or more, there occurs
no problem on operating the pump. If, however, a sudden drop appeared in the insulation
resistance even if the value is at or above 1MΩ, the phenomenon is abnormal, and repair of
the pump is required.
b) Every 6 months
Replace oil in the mechanical seal chamber at every six months. If water enters the oil to
give significant cloudiness, replace the mechanical seal. As illustrated in Fig. 6 oiling shall
be done at a specified quantity while the oiling plug faces upright and the pump is
positioned horizontally. After the oiling, fully tighten the plug with a seal washer.

-9-
c) Once a year
Replace mechanical seal at an interval of one year or 6000 hours of total operating hours,
either shorter one. By the replacement, the pump life extends.
d) Once every two to five years
Overhaul of the pump assures safe and long period of operation. For the case of high
frequency of operations, early overhaul is requested.
e) Check that there is no leakage from the joint of pump and piping. When there is leakage,
tighten the connection bolts.
f) In order to avoid the fire accident by the contact failure caused by the slack of wiring, check
whether motor connections and panel connections are not loosened.
3. Cautions when the pump is out of use for long period.
a) When you leave the pump submerged and out of use for long period, periodically measure
the insulation resistance. If the resistance values are greater than 1meg-ohms, operate the
pump for a while to prevent rotating parts from fastening by rust. Before starting the
operation again, refer to section (6)”operation”
b) When the pump is pulled up and stored.
Clean up the pump. And keep it at dry place. Before using the pump again, refer to sections
(5)”Installation”and (6)”Operation”.
4. When motor protection is activated
Check causes that motor protection is activated. After removing the causes, start the
operation again.
5. Consumable parts
