Installation

Receiving inspection
Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, file a claim immediately with the company that delivered the pump. If the manual is removed from the packaging, do not lose or misplace.

Storage
Any product that is stored for a period longer than six (6) months from the date of purchase should be bench tested prior to installation. A bench test consists of, checking the impeller to assure it is free turning and a run test to assure the motor (and switch if provided) operate properly.

Before Installation Insulation resistance measurement With the motor and cable (excluding the power supply cable) immersed in water, use a megger to measure the insulation resistance between ground and each phase of the motor, and again between each phase of the motor. The megger should indicate an insulation resistance of not less than 20 mega ohms. While making the measurement, keep the power supply cable off the ground. We recommend that an auxiliary pump be kept on hand in case of emergency.

Installation

WARNING Under no circumstances should the cable be pulled while the pump is being transported o r installed. Attach a chain or rope to the grip and install the pump.

1. This pump must not be installed on its side or operated in a dry condition. Ensure that it is installed upright on a secure base.
2. Install the pump at a location in the tank where there is the least turbulence.
3. If there is a flow of liquid inside the tank, support the piping where appropriate. Install piping so that air will not be entrapped. If piping must be installed in such a way that air pockets are unavoidable, install an air release valve wherever such air pockets are most likely to develop.
4. Do not permit end of discharge piping to be submerged, as backflow will result when the pump is shut down.

WARNING Non-automatic pumps do not have an automatic operating system Do not operate the pump for a long time with the water level near the lowest water level (H2) as shown in Figure 1, as the automatic cut-off switch incorporated inside the motor will be activated.

Wiring:

• a) Wire as indicated for the appropiate start system as shown in Figure 2.

• b) Loose connections will stop the pump. Make sure all electrical connections are secure.
  Cable
  WARNING

• c) Never let the end of the cable contact water.

• d) If the cable is extended, do not immerse the splice in water.

• e) Fasten the cable to the discharge piping with tape or vinyl strips.

• f) Install the cable so that it will not overheat. Overheating caused by coiling the cable and exposing it to direct sunlight.

Grounding:
Connect the green wire to ground. Under no circumstances should the green wire be connected to the power supply.

DANGER
Use short-circuit breakers to prevent danger of electrical shock.

Before Starting the Pump

1. After completing installation, measure the insulation resistance again as described in Installation.
2. 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 shut off the power. Constant operating in above condition will shorten pump life time. Do not start the pump again in such a situation before the motor has completely cooled.

Test operation

Non-automatic pump:

1. Turn the operating switch on and off a couple of times to check for normal pump start.
2. Next, check direction and 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 the wires.

Maintenance
Check pressure, output, voltage, current and other specifications. Unusual readings may indicate. Refer to Troubleshooting and correct as soon as possible.

Daily inspections:

1. Check current and ammeter fluctuation daily. If ammeter fluctuation is high, even though within the limits of pump rating, foreign matter may be clogging the pump. If the quantity of liquid discharged falls suddenly, foreign matter may be blocking the suction inlet.

Monthly inspections:

Measure the insulation resistance. The value should be more than 1M ohm. If resistance starts to fall rapidly even with an initial indication of over 1M ohm, this may be an indication of trouble and repair work is required.

Annual inspections:
To extend the service life of the mechanical seal, replace the oil in the mechanical seal chamber once a year. Water mixed with the oil or cloudy textures are indications of a defective mechanical seal requiring replacement. When replacing the oil, lay the pump on its side with filler plug on top. Inject suitable amount turbine oil no. 32 (ISO VG-32).

Inspections at 3-5 year intervals:
Conduct an overhaul of the pump. These intervals will preclude the possibility of future trouble.

Parts that will need to be replaced:
Replace the appropriate part when the following conditions are apparent. See Table 1. (Note: replacement schedule is based on normal operating conditions)

Maintenance option
Every cutter pumps is equipped with multiple suction plate gaskets. Throughout a period of time, the cutter ability and performance will drop as the impeller and suction plate start to wear. It is recommended to remove suction plate gaskets to reduce back the gap in order to maintain cutter’s slicing ability and hydraulic performance until the impeller and suction plate are completely worn out.

Disassembly
When disassembling pump, have a piece of cardboard or wooden board ready to place the different parts on as you work. Do not pile parts on top of each other. They should be laid out neatly in rows. The o-ring and gasket cannot be used again once they are removed. Have replacement parts ready. Disassemble in the following order, referring to the sectional view.

WARNING Be sure to cut off power source before disassembly.

1. Remove pump casing bolts, raise the motor section and remove pump casing.

2. Remove shaft head bolt and impeller.

3. Remove seal cavity oil filler plug and drain lubricating oil.

4. Remove intermediate casing bolts and intermediate oil chamber.(Remember that any lubricating oil remaining in the mechanical seal chamber will flow out.)

5. Carefully remove mechanical seal taking care not to scratch sliding surface or motor shaft.
   Assembly
   Re-assemble in reverse order of disassembly. Be careful of the following points:

6. During re-assembly, rotate the impeller by hand and check for smooth rotation. If rotation is not smooth, perform steps (3) through (5) again.

7. Upon completion of re-assembly step 1 rotate the impeller by hand from the suction the suction inlet and check that it rotates smoothly without touching the suction cover before operating the pump.
   Please obtain o-rings, packing, shaft seals and other parts from pump dealer.

Installing the QL-100
Remove both hex bolts and use the M12 x 30 hex bolt to assemble back the suction plate to the volute.
