OPERATION
PRIMING THE PUMP
Do not run pump with discharge shut off. Pump
can boil water, causing steam burns when opening pump, blowing
up pump body, or causing internal (seal) damage to pump.
NEVER run pump dry. Running pump without
water may overheat pump, damaging internal parts and caus-
ing burns if handled. To prevent damage, fill pump with water
before starting.
1. Remove priming plug.
a. Fill pump and suction pipe with water.
b. Replace priming plug, using Teflon tape on plug thread;
tighten plug.
NOTICE: If priming tee and plug have been provided for
long horizontal run, be sure to fill suction pipe through this
tee and replace plug (remember to teflon tape the plug).
2. Start pump and run two minutes or less. Unit should pump water.
If not, stop pump and repeat steps under No. 1. On first use of
pump, it may be necessary to reprime unit 2 - 3 times before all
air is out of suction pipe.
3. If, after priming pump several times, no water is pumped, make
sure that:
a. Suction pipe end is in water.
b. Suction pipe has no air leaks.
c. Pump is not trying to lift water more than 25 ft.
d. Pump is not air locked: Pump suction port should be high-
est point in suction pipe; no sags in suction pipe (run it
straight and angled slightly upward from well head to
pump).
e. Piping is clean and in good condition.
NOTICE: As long as foot valve and check valve function
correctly and suction pipe does not develop leaks, pump
should not need repriming in normal service.

SERVICE
Risk of electrical shock. Be sure unit is ground-
ed and power disconnected before attempting any work on
pump or motor.
Your pump is designed for ease in servicing. Should repair or
replacement of the motor or seal be needed, the pump and piping
do not need to be disconnected or disturbed.
(FIG. 10)
(If it is necessary to replace the motor, it is a good idea to replace
the seal plate "O" Ring and the shaft seal, Key Nos. 4 and 6, Page
10. We suggest that you order these two items to have on hand for
future use.)
MAINTENANCE
It is not necessary to lubricate the pump or its motor. The motor
bearings are lubricated for life. The mechanical shaft seal in the
pump is water lubricated and self-adjusting.
1. Disconnect power.
2. Remove pressure switch tube from pump body and allow pump
3. Remove four hexnuts (Key No. 23, Page 11) which hold the
4. Remove motor, seal plate, impeller and diffuser (Key Nos. 1, 3,
5. Carefully insert an icepick or other small diameter pointed tool
6. Foreign matter will drop to the bottom of the pump body (directly
7. Install new "O" Ring gasket on seal plate (Key No. 4, Page 11).
8. Pick up small amount of liquid soap on finger; spread evenly over
9. Replace motor onto pump body. Be sure rubber pad (Key No. 8,
10. Replace pressure switch tubing and motor wiring.
11. Prime pump according to instructions above.
12. Check for leaks.
1. Follow steps 1 through 4 under Cleaning Shallow Well Jet
2. Remove venturi (Key No. 17, Page 11) by unscrewing it (turn
3. Remove nozzle (if necessary) by unscrewing it with a 5/8" hex
4. Replace nozzle and venturi by turning in clockwise until snug. Do
5. Follow steps 7 through 12 under Cleaning Shallow Well Jet
1. Follow steps 1 through 4 under Cleaning Shallow Well Jet
2. Remove two screws (Key No. 10) fastening diffuser (Key No. 9,
3. Exposed impeller (Key No. 7, Page 11) can now be cleaned.
4. If impeller must be replaced, loosen two machine screws and
5. If motor has capacitor, partially unscrew capacitor clamp and
