Setup and Installation
Professional installation is highly recommended for this product to ensure proper function and compliance with all safety and plumbing codes.
- Site Preparation: Ensure the sewage basin or sump pit is clean, free of debris, and adequately sized for the pump. The basin must be vented according to local plumbing codes.
- Pump Placement: Carefully lower the pump into the basin. Ensure it rests on a solid, level surface, not directly on the bottom to prevent clogging from sediment.
- Discharge Piping: Connect the pump's discharge outlet to the discharge piping system. Use appropriate check valves and gate valves as required by local codes to prevent backflow and allow for isolation. Ensure all connections are watertight.
- Float Switch Adjustment: The tethered float switch controls the pump's on/off cycles. Adjust the tether length to set the desired 'on' and 'off' levels. Ensure the float can move freely without obstruction within the basin. The 'on' level should be high enough to prevent frequent cycling, and the 'off' level should prevent the pump from running dry.
- Electrical Connection: Connect the pump to a dedicated, properly grounded electrical circuit with appropriate overcurrent protection. Use a GFCI (Ground Fault Circuit Interrupter) outlet if required by local codes. Ensure the power cord is not pinched or damaged.
- Test Operation: After installation, fill the basin with water to the 'on' level to verify the pump activates, discharges water, and shuts off correctly when the water level drops to the 'off' level. Check for any leaks.
Operating Instructions
The PROFLO PF93015 sewage pump operates automatically via its tethered float switch.
- Automatic Operation: When the wastewater level in the basin rises and lifts the float switch to its 'on' position, the pump will activate and begin discharging the wastewater.
- Shut-off: As the wastewater level drops and the float switch returns to its 'off' position, the pump will automatically shut off.
- Continuous Monitoring: Periodically check the pump's operation to ensure it is cycling correctly and effectively removing wastewater.
Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your sewage pump.
- Monthly Inspection: Visually inspect the pump and basin for any signs of damage, excessive debris, or obstructions around the float switch. Ensure the float switch moves freely.
- Cleaning: If excessive solids or debris accumulate in the basin, disconnect power to the pump, remove it from the basin, and clean the pump intake screen and impeller area. Always wear appropriate PPE during cleaning.
- Check Valves: Periodically inspect any check valves in the discharge line to ensure they are functioning correctly and not allowing backflow.
- Power Cord: Inspect the power cord for any cuts, abrasions, or damage. Replace if necessary.
Troubleshooting
Before troubleshooting, always disconnect power to the pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power to pump Float switch stuck in 'off' position Motor overload Clogged impeller | Check circuit breaker/GFCI Inspect float switch for obstructions Allow motor to cool; check for cause of overload Disconnect power, clear impeller |
| Pump runs continuously | Float switch stuck in 'on' position Check valve failure Pump airlocked | Inspect float switch for obstructions Inspect and replace check valve if necessary Disconnect power, restart pump to clear air |
| Pump runs but does not pump water or pumps slowly | Clogged intake or impeller Discharge pipe obstruction Low voltage Air lock | Disconnect power, clear intake/impeller Inspect discharge piping for blockages Verify proper voltage supply Disconnect power, restart pump to clear air |
