MAINTENANCE

Risk of personal injury, or damage to pump or other equipment.
• Before working on pump, always disconnect pump power cord in addition to shutting off circuit
breaker or removing the fuse. Always wear eye protection.
• This pump is equipped with a cutting mechanism that has very sharp edges. Use caution when
working on or near these parts.
• Do not remove motor housing seal plate screws. The motor section of the pump is permanently
lubricated with dielectric oil and sealed at the factory. Removal of these screws by anyone other than
an authorized service center will break the seal and void the warranty.

Disconnect Power

If service is required, proceed carefully. The pump and surrounding areas may be covered with water. Never plug
in or unplug the device while standing in wet or damp surfaces. If necessary, remove power at the Breaker Panel
or have certified electrician remove power before attempting to service. Serious or fatal shocks could result if
proper procedures are not followed. Disconnect the power at the main electrical service box by switching off the
appropriate circuit breaker or removing fuse. In applications where screw type fuses are used, remove using only
one hand while the other hand and torso are free from contact with anything. Do not stand in water and do not
touch any other conductive surfaces.

Thermal Protection

The motor is a continuous duty type equipped with an automatic resetting heat sensor and may restart unex-
pectedly. Heat sensor opening is an indication of motor overloading/overheating, which can be caused by appli-
cation 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.
