Maintenance; Periodic Service - Little Giant 15SC-CIA-RF Owner's Manual

MAINTENANCE

Risk of severe injury or death by electrical shock, high
temperatures, or pressurized fluids.
• Always unplug the pump power cord in addition to removing the fuse or shutting off the circuit breaker before
working on the pump or switch.
• 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. Remove power to the system.
2. Check the power cords and electrical outlet for damage or corrosion.
IMPORTANT: The unit must be replaced if the power cord is damaged.
3. Remove all debris (gravel, sand, floating debris, etc.) from the basin.
4. 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.
5. Confirm all flexible coupling hose clamps are fully tightened.
6. Refer to "Operation" on page
