The Zoeller AquaNot Spin 508 is a self-testing battery backup sump pump system. Key operational requirements include using a deep-cycle battery (size 27, 29, or 31) and ensuring the installation pit is at least 16 inches in diameter and 22 inches deep. All electrical work must be performed by a qualified licensed electrician in accordance with NEC and OSHA codes.
System Overview
The system consists of a 12-volt DC pump, a controller that monitors battery health and pump status, and a battery case. The controller features multi-stage charging and self-testing diagnostics to ensure the system is ready during power outages.
Controller Alerts
The controller provides status updates via LED indicators:
- System Ready: Green light indicates no faults.
- Battery: Green (Charged), Yellow (Charging), Red (Low Battery/Bad Battery).
- DC Pump: Yellow (Pump Running/Ran), Red (Pump Fault).
- Float Status: Red (High Water/Float Fault).
Installation Requirements
- Pit Size: Minimum 16" (40 cm) diameter by 22" (56 cm) deep.
- Battery: Deep-cycle, size 27, 29, or 31.
- Wiring: All controls and wiring must be installed by a qualified licensed electrician.
- Float Switch: The off-level of the float assembly must be higher than the DC backup pump.
Performance Data
The system is rated for a shut-off head of 22 ft (6.7 m). Performance is based on a fully charged 12-volt deep-cycle battery. Estimated battery life during continuous operation is approximately 5.5 hours (based on 175-minute reserve capacity).
Maintenance and Safety
The pump includes an integrated check valve and a quick-disconnect discharge. Regularly test the system using the 'Test' button on the controller. If an alarm sounds, press the 'Alarm Silence/Reset' button to silence it, or press and hold for three seconds to reset.
Practical help
Common problems
Pump Fault (Red LED)
Indicates a pump fault; check for obstructions or electrical connection issues.
Low Battery (Red LED)
Battery voltage is low; check battery charge level or replace the battery if it fails to hold a charge.
High Water (Red LED)
Water level is high; check the float switch or the optional reed sensor for proper operation.
Before use
- Verify the battery is a deep-cycle type, size 27, 29, or 31.
- Ensure the installation pit is at least 16 inches in diameter and 22 inches deep.
- Confirm the off-level of the float assembly is positioned higher than the DC backup pump.
- Ensure all electrical connections are performed by a qualified licensed electrician.
- Test the system using the 'Test' button on the controller.
Specs in practice
