runs out of the priming port.

3. Replace priming plug, hand tight.

IL0125

Figure 6

4. Start the pump. Unit should pump water within

30 seconds. If not, stop pump and repeat steps1 through 3. On first use of pump, it may be

necessary to re-prime the unit three or four

times before all the air is out of suction pipe.

IMPORTANT: If the pump fails to build prime,

there may be an air pocket in the pump case.

To break up trapped air, connect 1/4 plastic

tube, using a brass ferrule connector, to the

priming air vent port. (Not supplied.)IMPORTANT: With the pump case completely

full of water and the priming tee plug in place,

submerge tubing into a bucket of water. Turn

on power to motor. When pump builds up

pressure, turn off power, remove tubing and

ferrule connector and replace 1/4 plug (See

Figure 6.)

5. Once the pump is primed, tighten the primingplug. Remember to close the faucets.

Once the preceding instructions have been

completed, the pump can be started.

1. During the first few hours of operation, inspectthe pump, piping and any auxiliary equipment

used in connection with the unit.

2. Check for leaks, excessive vibration or unusualnoise.

IMPORTANT: Flow into well must at least equal

flow out through pump! See Performance Chart B.

Never examine, make wiringchanges or touch the motor before disconnecting the

main electrical supply switch. The thermal device may

have opened the electrical circuit.

Motor Protection

All single phase motors have built-in thermalprotection for all voltages. The overload protects

the motor against burnout due to low voltage, high

voltage and other causes. The device is automatic

and resets itself once the temperature has droppedto a safe point. Frequent tripping of the deviceindicates trouble in the motor or power lines, and

immediate attention is needed.

Disconnect power supply and

de-pressurize system before servicing pump or

removing any component.

Lubrication

The motor has pre-lubricated bearings. No

lubrication is required.

temperature, the pump should be drained when it isnot in service or in danger from freezing.

Winterizing (Continued)

1. Disconnect power.

2. Slowly and carefully release all water pressure.

3. Drain suction pipe to a point below the frost line.4. Drain all piping exposed to freezing

temperatures.

5. Remove the 1/4 drain plug located on thebottom of the pump body (See Figure 1).

6. Remove the priming plug from service tee to

vent pump.

7. Drain pressure tank.

Pump Disassembly

To disassemble the pump, refer to Fig. 14 and the

following instructions.

1. Disconnect power to motor.

2. Remove for (4) hex bolts (Ref. No. 18) andremove the pump body (Ref. No. 10) from motor.

3. Remove three (3) hex bolts and washers (Ref.

No. 17) and remove diffuser (Ref. No. 7) anddiffuser plate (Ref. No. 9).

NOTE: The seal ring (Ref. No. 6) is generally

reusable. However, check to see if cut or damagedand replace if necessary.

Cleaning/Replacing Impeller

(See Figure 15)

NOTE: First, follow instructions under PumpDisassembly.

1. With diffuser removed, (Ref. No. 7) the exposedimpeller can now be cleaned.

2. Remove impeller (Ref. No. 5) by unthreading

counter-clockwise while looking into the eye of

impeller. To hold motor shaft, remove two (2)screws (Ref. No. 16) and remove motor end cap.

Use the screwdriver shaft at the back of motor

shaft.

3. To reinstall, reverse steps 1 and 2 and re-mount

diffuser.

4. Re-assemble the pump body (Ref. No. 10) to themotor bracket (Ref. No. 19).

NOTE: Because damage to the shaft seal canoccur in disassembly, a new seal will be required.

Mechanical Seal Replacement

(See Figure 15)

1. Follow instructions under Pump Disassembly.

2. Follow steps 1 and 2 under Cleaning/Replacing

Impeller.

3. Remove the mechanical seal assembly.

a. Using two screwdrivers, pry the rotaryportion of the seal assembly (carbon ring,

Buna-N gasket and spring) off the end of

the shaft.

b. Using two (2) screwdrivers, pry the ceramic

seal and rubber gasket from the recess of

the mounting ring (See Figure 9).

The precision lapped faces ofthe mechanical seal are easily damaged. Handlethe replacement seal carefully. Short seal life will

result if seal faces (ceramic & carbon) are nicked,

scratched or dirty.

4. Clean the seal cavity of the motor bracket and

the motor shaft thoroughly.

5. Wet outer edge of rubber cup on ceramic seatwith liquid soap solution. Use sparingly (one

drop only).

NOTE: Liquid soap solution one drop of liquidsoap combined with one teaspoonful of water.

6. With thumb pressure, press ceramic seal halffirmly and squarely into seal cavity. Polishedface of ceramic seat is up. If seal will not seat

correctly, remove, placing seal face up on bench.

Reclean cavity. Seal should now seat correctly

(See Figure 10).

7. If seal does not seat correctly after recleaning

cavity, place a cardboard washer over polished

seal face and carefully press into place using

a piece of standard clean 3/4 pipe as a press(See Figure 11).

IMPORTANT: Do not scratch seal face.

8. Dispose of cardboard washer and recheck seal

face to be sure it is free of dirt, foreign particles,

scratches and grease.

9. Inspect shaft to be sure it is free of nicks and

scratches.

10.Apply liquid soap solution sparingly (one drop is

sufficient) to inside diameter of rubber rotating

member.

11.Slide rotating seal member (carbon face down

toward ceramic face) and spring over the shaft.

IMPORTANT: Be sure not to nick or scratch carbonface of seal when passing it over threaded shaft

end of shaft shoulder. The carbon surface must

remain clean, or short seal life will result.

12.Hold motor shaft with flat blade screwdriver andscrew impeller onto shaft. Tightening impeller

will automatically locate seal in correct position.

13.If removed for inspection remount seal ring anddiffuser to the motor mounting ring.

14.Reassemble the pump body (Ref. No. 10) to the

motor mounting bracket.
