Safety Information
Always disconnect power before servicing the pump or system. Ensure all electrical connections comply with local codes. Wear appropriate personal protective equipment (PPE) during installation and maintenance. Do not operate the pump dry.
Setup and Installation
The 1102RP pump is designed for direct replacement in S1101 and S1102 systems. Professional installation is recommended.
- Preparation: Ensure the existing system is completely drained and disconnected from power. Remove the old pump carefully.
- Placement: Position the new 1102RP pump securely within the sewage ejector basin. The pump is heavy-duty and may not require the original mounting bracket from older, lighter models.
- Piping Connection: Connect the pump's discharge outlet to the existing discharge piping. Ensure a tight, leak-free connection.
- Float Switch Adjustment: Verify the float switch operates freely and is set to activate the pump at the appropriate liquid level and deactivate it before the basin empties completely.
- Electrical Connection: Connect the pump's power cord to a grounded electrical outlet, ensuring it is on a dedicated circuit as per local electrical codes.
- Testing: Once installed, slowly fill the basin with water to test the pump's activation and deactivation cycles. Check for any leaks.

Operating Instructions
The Star 1102RP pump operates automatically via its integrated float switch. When the liquid level in the basin rises to the activation point, the pump will turn on and discharge the contents. It will turn off once the liquid level drops to the deactivation point.
- Ensure the pump is always submerged when operating to prevent dry running.
- Do not dispose of non-biodegradable items, excessive grease, or harsh chemicals into the system, as this can damage the pump.
- Listen for unusual noises during operation, which may indicate a problem.
Maintenance
Regular maintenance ensures the longevity and efficiency of your 1102RP pump.
- Annual Inspection: Annually inspect the pump and basin for debris buildup. Clear any obstructions around the float switch and pump intake.
- Check Connections: Periodically check all piping and electrical connections for tightness and signs of wear.
- Clean Basin: If accessible and safe, periodically clean the basin to prevent accumulation of solids that could impede pump operation.
- Float Switch Check: Manually lift and lower the float switch to ensure it moves freely and activates/deactivates the pump correctly.
Always disconnect power before performing any maintenance.
