MAINTENANCE
Risk of severe injury or death by electrical shock, high temperatures,
or pressurized fluids.
• Always unplug the primary pump power cord, charger, and battery connections in addition to removing the fuse
or shutting off the circuit breaker before working on the pump, switch, or other backup system components.
• Let pump cool for a minimum of 2 hours before attempting to service. Submersible pumps can become pressur-
ized and hot under normal operating conditions.
Risk of damage to pump or other equipment.
• This unit is permanently lubricated. Oiling is not required. Do not open the sealed portion of the unit or remove
housing screws.
• Do not remove the impeller. This action requires special tools and may damage the pump.
• Warranty is void if the motor housing cover, impeller, or seals have been removed. Repairs on the motor or impel-
ler require special tools.
Periodic Service
Inspect and test the pump system condition and operation every three months—more frequently in
heavy use applications.
1. Check the power cords and electrical outlet for damage or corrosion.
IMPORTANT: The unit must be replaced if the power cord is damaged.
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 plumbing fixtures are secure, not damaged, and functioning as intended.
5. Test operation of the pump system. Refer to
"Operation Testing" on page
