Maintenance; Periodic Service - red lion RL-SC33T Owner's Manual

4. Run water into the basin until the pump is activated.
5. Make sure the pump and its float switch are functioning as intended.
• Confirm that no potential obstructions exist that could inhibit switch operation.
NOTE: It is normal for a stream of water to spray from the air relief bleed hole in the pump's
plumbing. Verify that this spray is captured within the basin.
• Verify the ON/OFF levels are within specification.
NOTE: If the pump doesn't turn on, test manual operation by connecting the pump's power plug
directly into the power source. If the pump runs, test the float switch.
6. Confirm that there are no leaks in the pump discharge
plumbing and main home drain pipe plumbing.
7. Allow the pump to operate through several ON/OFF
cycles.
8. Use an ohmmeter to check for continuity between the
incoming and outgoing connections of the piggyback
plug while raising and lowering the float.

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, 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: If the power cord is damaged, the whole unit must be replaced.
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, and clean as required. If significant,
replace affected components.
4. Confirm all flexible coupling hose clamps are engaged with plumbing and fully tightened.
5. Test operation of the pump system. Refer to "Operation Testing" on page
