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.
• Do not remove motor housing seal plate screws or top motor housing 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.
Risk of damage to pump or other equipment.
• Periodically inspect pump and system components. Regularly check hoses for weakness or wear,
making certain that all connections are secure.
• Schedule and perform routine maintenance as required and in accordance with the Maintenance
section of this manual.
Disconnect Power
• The pump and surrounding areas may be covered with water. Never plug in or unplug the device while
standing in wet or damp surfaces. Do not stand in water and do not touch any other conductive sur-
faces.
• If necessary, remove power at the breaker panel or have a certified electrician remove power before
attempting to service. Serious or fatal shocks could result if proper procedures are not followed. Dis-
connect 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.
Periodic Service
Inspect and test the pump system condition and operation every 3 months—more frequently in heavy-use
applications.
Let pump cool for a minimum of 2 hours before attempting to service. Submersible pumps contain oil that
becomes pressurized and hot under normal operating conditions.
1. Check the power cords and electrical outlet for damage or corrosion.
2. Remove all debris (gravel, sand, floating debris, etc.) from the basin.
3. Check the pump system components (basin, pump, switch, etc.) for any build-up (sludge, sediment,
minerals, etc.) that would inhibit functionality of the components. If significant, remove build-up or
replace affected components.
4. Confirm that all flexible coupling hose clamps are fully engaged with plumbing and fully tightened.
5. Test operation of the pump system.
6. While the pump is running, make sure a stream of water is escaping from the air bleed hole. If not, clear
the hole of any deposits or debris.
