Safety Information
Always observe the following safety precautions:
- Ensure the power supply is disconnected before performing any installation or maintenance.
- Verify that the voltage of the power supply matches the toilet's requirements (12V DC).
- Do not dispose of foreign objects (e.g., paper towels, sanitary products, chemicals) into the toilet as this can cause blockages or damage.
- Ensure proper ventilation in the installation area.
- All electrical connections must be waterproof and comply with marine electrical standards.
Setup and Installation
Follow these steps for proper installation:
- Mounting Location: Choose a stable, level surface for mounting. Ensure adequate space for maintenance and plumbing connections. The toilet supports both left and right-handed installations.
- Water Inlet Connection: Connect a 3/4" water supply hose to the inlet port. The self-priming pump can use raw or fresh water.
- Discharge Connection: Connect a 1" discharge hose to the outlet port. Ensure the discharge hose has a continuous downward slope to prevent standing water. The built-in backflow preventer helps maintain hygiene.
- Electrical Wiring: Connect the toilet to a 12V DC power source. The maximum current draw is 20A at 12V. Ensure connections are secure and protected from moisture.
- Testing: After installation, perform a test flush with clean water to check for leaks and proper operation of the flush mechanism.

Operating Instructions
The SEAFLO Electric Marine Toilet is operated via a push-button activated control panel.
- Flushing: Press and hold the flush button. The flexible impeller flush pump will activate, drawing water into the bowl and macerating waste for discharge. Release the button when flushing is complete.
- Water Conservation: For liquid waste, a shorter press of the button is sufficient. For solid waste, a longer press ensures thorough maceration and discharge.
- Winterization: Before winter storage, ensure all water is drained from the system to prevent freezing damage. Flush with non-toxic antifreeze solution.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your marine toilet.
- Cleaning: Use mild, non-abrasive cleaners for the ceramic bowl and exterior surfaces. Avoid harsh chemicals that can damage seals or internal components. The ceramic bowl with enamel finish is designed for easy cleaning.
- Impeller Inspection: Periodically inspect the flexible impeller flush pump for wear. Replace if signs of damage or reduced performance are observed.
- Hose Connections: Check all hose clamps and connections regularly for tightness and signs of leaks.
- Electrical Connections: Ensure electrical connections remain clean, dry, and free of corrosion.
