Periodic Service

MAINTENANCE
Risk of severe injury or death by electrical shock, high
temperatures, or pressurized fluids.
• Always disconnect the electrical power before touching the pump.
• 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.
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 motor housing cover, impeller, socket head cap screws, or seals. Warranty is void if the motor
housing cover, impeller, or seals have been removed. Repairs on the motor or impeller 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, etc.) for any build-up (sludge, sediment, miner-
als, 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.
Cleaning Impeller and Volute
1. Remove the screws that hold the base to the volute.
2. Separate the base and volute.
3. Clean the impeller and volute passage.
IMPORTANT: Do not use strong solvents on the impeller.
4. Ensure the impeller freely rotates after cleaning.
5. Reattach the base to the volute and secure it with the screws.
