Operating Instructions and Parts Manual

OPERATION

Never run the pump dry. Running pump without
water may cause seal damage. Fill the pump with water before starting.
MISE EN GARDE
Ne jamais faire fonctionner la pompe
à sec. La faire fonctionner sans eau risque d'endommager le joint.
Remplir la pompe avec de l'eau avant de commencer.
PRIMING THE PUMP
After pump installation is complete, the pump must be primed. Remove
the pipe plug in the discharge piping and fill the pump and suction pipe
with clean water. Turn power to pump on. If the pump does not pump
water in 10 minutes, turn off the pump and refill with clean water.
If the pump does not operate after repeated attempts, check the
following:
1. Vertical distance of pump to water level must not be over 25 feet.
2. If sucking air, suction piping must be air tight.
3. Be sure valve(s) are open if used in discharge or suction piping.
Never run the pump with a closed or clogged
discharge. The water inside the pump could boil and damage the pump.
MISE EN GARDE
Ne jamais faire fonctionner la pompe
si la décharge est fermée ou obstruée. L'eau à l'intérieur de la pompe
pourrait bouillir et l'endommager.

MAINTENANCE

Maintain adequate ventilation for the pump
motor. The motor bearings are permanently lubricated at the factory.
Additional lubrication is not required.
DRAINING FOR WINTER
Always protect pump and piping against freezing temperatures. If there is
any danger of freezing, drain the system. To drain the system:
1. Remove the pipe plug from the discharge tee.
2. Remove the 1/4" plug from the lower front face of the pump.
3. Drain all piping below the frost line.
LAWN SPRINKLER REBUILD KIT (SEE PAGE 10)
1. Disconnect all power from the pump
2. Drain the pump and disconnect any plumbing.
3. Remove the four bolts holding the volute to the seal plate.
4. Remove the volute from the seal plate, you may need to use a
screwdriver to help separate the parts.

5. Remove the square cut gasket from the seal plate and discard.
6. Remove the three screws from the diffuser assembly, and then
remove the diffuser from the seal plate. The intake on the diffuser
has an O-Ring seal and is covered with a lubricant, remove the
O-Ring and discard.
7. Remove the black end cap from the back of the motor, exposing
the motor shaft end (on the WLS200 you will have to remove the
plastic cover from the end of the motor).
8. Use a large flat blade screw driver to hold the motor shaft while
unscrewing the impeller.
9. Remove the bellows portion of the shaft seal, making sure the metal
sleeve comes off as well, all you should see on the back of the
impeller is the brass colored threaded insert.
10. Remove the ceramic seal and rubber boot from the seal pate, it
is easier to remove the seal by unbolting the seal plate from the
motor flange. If you remove the seal plate from the motor flange
make sure you torque the four bolts to 140 ±40 inch pounds when
reassembling it.
11. Wipe down all the parts to remove any debris or loose rust.
12. Reassemble the pump with new parts in reverse order.
13. Push the ceramic seat of the shaft seal into the seal plate using the
cardboard ring provided to keep the ceramic face clean. You can
use a little water or dish soap to lubricate the seal pocket to make
assembly easier.
14. Push the bellows side of the shaft seal over the impeller hub, you
can use a little water or dish soap to lubricate the impeller hub to
make assembly easier.
15. Holding the motor shaft with a flat blade screw driver, thread the
impeller onto the motor shaft, hand tighten.
16. Replace the end cap (or plastic cover on the WLS200) over the
motor shaft end.
17. Put a new O-Ring on the diffuser and lubricate (with petroleum jelly
the intake/O-Ring area of the diffuser with the same lubricant used
on the impeller.
18. Replace the diffuser, rotating the diffuser until the screw holes line up
with the ones in the seal plate. The diffuser only goes on one way.
Torque the screws to 27±7 inch pounds.
19. Slide the square cut gasket over the flange on the seal plate, make
sure not to let the gasket twist.
20. Reassemble the volute to the pump being careful not to damage
the O-Ring on the diffuser. Torque the four bolts to 240 ±40 inch
pounds.
21. Reattach plumbing connection, reconnect the power and prime the
pump (See section on priming the pump). After reassembling the
pump, check for leaks. If a leak is detected, repair before using the
pump.
