Setup
- Placement: Position the pump on a firm, level surface in the area where water removal is needed. Ensure the pump is stable and will not tip over.
- Discharge Hose Connection:
- Connect a standard 1-1/4 inch NPT discharge hose to the pump's outlet.
- If using a garden hose, attach the included 3/4 inch garden hose adapter to the pump's discharge port, then connect your garden hose.
- Ensure all connections are tight to prevent leaks.

- Discharge Route: Route the discharge hose to a suitable drainage area, ensuring the water is directed away from the area being drained and does not create a new flooding hazard. Avoid kinks or sharp bends in the hose.
- Electrical Connection: Plug the pump into a standard 115 Volt, 60 Hz, GFCI-protected electrical outlet. Ensure the power cord is not submerged in water and is protected from damage.
- Check Valve (Recommended): For optimal performance and to prevent water from flowing back into the area being drained, it is highly recommended to install a check valve in the discharge line. This is especially important if the discharge point is higher than the pump.
Operating Instructions
The Superior Pump 91246 is an automatic utility pump, designed to operate without constant supervision once properly set up.
- Automatic Operation: The pump will automatically activate when the water level reaches approximately 1-1/2 inches above the base of the pump. It will continue to pump water until the level drops to approximately 1/8 inch, at which point it will automatically shut off.
- Initial Start-up: After connecting the pump and power, if water is present above the activation level, the pump should start automatically. If it does not, ensure the power connection is secure and the float mechanism is not obstructed.
- Monitoring: Periodically check the pump's operation to ensure it is functioning correctly and that the discharge path remains clear.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Disconnect Power: Always unplug the pump before any maintenance or cleaning.
- Clean Intake Screen: Periodically inspect and clean the intake screen at the bottom of the pump to remove any debris (leaves, sediment, small solids) that may obstruct water flow. The pump can handle solids up to 1/8 inch, but larger debris can cause clogs.
- Check for Obstructions: Ensure the float mechanism moves freely and is not obstructed by debris or the pump's surroundings.
- Inspect Power Cord: Check the power cord for any signs of damage, cuts, or fraying. Replace immediately if damage is found.
- Winterization: If the pump is used in an area where temperatures drop below freezing, remove the pump from service, clean it thoroughly, and store it in a warm, dry location to prevent freezing damage.
