Thermal Protection
Risk of personal injury or damage to pump or other equipment.
•
Equipment can start automatically. Always unplug the pump power cord and disconnect the electri-
cal power before servicing the pump.
The motor is a continuous duty type equipped with an automatic resetting heat sensor and may restart
unexpectedly. Heat sensor opening is an indication of motor overloading/overheating, which can be caused
by application issues such as:
•
an obstructed pump impeller
•
switch stuck in the ON position
•
pump running dry
•
pump air locked
•
pump short cycling
•
operating the pump at low heads (low discharge restriction)
•
excessively high or low voltage supply
•
inadequate wiring
•
incorrect motor connections
•
mis-application of the product
•
pump, motor, bearings, or seal that have reached the end of their useful life.
Any of these conditions must be corrected to extend the life of the pump.
Wear Plate Adjustment
Wear plate parts:
1.
Locking bolt
2. Adjustment bushing
3. Wear plate
4. Impeller
To adjust the wear plate:
1.
Loosen the locking bolt (1) and adjustment bushing (2).
2. Press wear plate (3) until it makes contact with the impeller (4).
3. Advance the adjustment bushings (2) until they touch the pump housing.
4. Slightly tighten to advance bushing (2) so the impeller (4) turns freely.
•
Make sure the impeller spins freely and the clearance between the wear plate
and the impeller is less than 0.04" (1 mm).
5. Fully tighten the locking bolt (1) to the adjustment bushing (2) to prevent loosen-
ing or movement.
6. Repeat adjustment process if necessary.
