User Manual for Zoeller Aquanot 508 Spin 12V DC Battery Backup Pump

Quick guide from the manual

The Zoeller Aquanot 508 Spin is a self-testing 12V DC battery backup sump pump system designed to protect against flooding during power outages or primary pump failure. Before installation, ensure you have a 115V grounded receptacle available and that the primary pump and controller are on separate circuits. The system requires a 12V deep-cycle marine battery (100+ amp hour recommended). Do not use gel or automotive batteries.

Product Description

This system features smart diagnostics and self-testing capabilities. It is designed to purge air and remedy air lock situations automatically. The controller monitors the battery, pump status, and float switches. It includes a multi-stage charger to maintain battery health.

Installation

Pre-installation: Ensure the discharge piping is 1-1/2 inch SCH 40 PVC. Disconnect power to the primary pump before starting.

1. Remove all parts from the shipping carton.
2. Select a location for the battery and controller within 8' of a 115V outlet and 6' of the pump.
3. Install the check valve assembly into the primary pump discharge.
4. Secure the discharge tee onto the check valve using a hose clamp.
5. Install the operational float switch above the "on" level of the primary pump using the provided clamp. Ensure the float moves freely.
6. Install the optional high water switch with the "on" level at least 1" above the operational float.
7. Mount the Spin controller using the provided anchors, at least 3' above the sump.
8. Connect the DC pump plug to the controller.
9. Connect the battery leads: Positive (+) to the positive terminal, black negative (-) to the negative terminal.
10. Plug the controller into the 115V wall outlet.

Initial Start-up and Operation

When first plugged in, all lights will flash and the alarm will sound to verify functionality. The system expects the operational switch to be connected. If not, alarms will sound. To reset, hold the Silence button for 3 seconds.

Testing: Run water into the sump to test the installation. The DC pump should activate. If the pump runs but does not pump water, the controller will attempt to purge air. The yellow DC Pump LED will remain on if the pump successfully pumped water.

Maintenance

Inspect and test the system every 3 months:

• Unplug the primary pump and controller.
• Fill the sump with water to the "on" level and allow the pump to run.
• Verify the alarm sounds after 1 second.
• Push the Silence/Reset button to stop the alarm.
• Reset the controller by holding the Silence/Reset button for 3 seconds.
• Plug the units back into the wall outlet.

Troubleshooting

• Pump won't run: Check connections, battery charge, and the 30A fuse on the controller.
• Pump runs but pumps little/no water: Check for airlock, clear the weep hole, and ensure discharge piping is not blocked.
• Pump cycles too frequently: Adjust the rubber stops on the operational float rod.
• Alarm sounds during recharge: Unplug the charger, check the battery, and reconnect.

Battery Selection

Use a B.C.I. size 27 deep-cycle battery with 175-minute reserve capacity or larger. Replace the battery every 3 years. Do not let corrosion build up on terminals. For wet cell batteries, check electrolyte levels monthly.
