Setup Instructions
- Separate Tanks: Release the quick-release latches to separate the upper fresh water tank from the lower holding tank.
- Fill Fresh Water Tank: Unscrew the fresh water tank cap and fill the upper tank with clean water. For optimal sanitation, add a recommended portable toilet chemical or deodorizer to the fresh water. Do not overfill. Securely replace the cap.
- Prepare Holding Tank: Ensure the pour spout is securely closed and stored in its compartment. Add a small amount of water (approximately 1-2 liters) and the recommended amount of portable toilet chemical or deodorizer directly into the holding tank via the waste valve opening.
- Reassemble: Align the upper and lower tanks and securely fasten the quick-release latches until they click into place. Ensure a tight seal between the two sections.
- Placement: Place the assembled portable toilet on a flat, stable surface.
Operating Instructions
Flushing the Toilet
- Open Waste Valve: Before use, pull the waste valve handle (typically located on the front of the lower tank) to the open position. This allows waste to drop into the holding tank.
- Use: After use, close the lid.
- Flush: Operate the piston pump by pushing it down and pulling it up several times. This will draw water from the fresh water tank and rinse the bowl. The two-directional rinse ensures thorough cleaning.
- Close Waste Valve: Push the waste valve handle back to the closed position to seal the holding tank and prevent odors.
Monitoring Tank Levels
The Visa Potty is equipped with easy-to-read level indicators for both the fresh water and waste holding tanks. Regularly check these indicators to know when to refill the fresh water tank or empty the waste holding tank.
Emptying the Holding Tank
- Separate Tanks: Ensure the waste valve is closed. Release the quick-release latches and separate the upper fresh water tank from the lower holding tank.
- Transport: Carry the lower holding tank to an approved waste disposal site.
- Open Pour Spout: Detach the pour spout from its storage compartment and securely attach it to the holding tank's discharge opening.
- Vent Tank: Open the holding tank vent (usually a small cap or button) to allow for smooth and splash-free emptying.
- Empty: Carefully pour the contents of the holding tank into the disposal site.
- Rinse: Rinse the holding tank with clean water, if possible, and empty again.
- Close: Close the vent, remove and clean the pour spout, and return it to its storage compartment.
- Reassemble: Reattach the holding tank to the fresh water tank.
Maintenance and Cleaning
- Regular Cleaning: Clean the toilet bowl and exterior surfaces regularly with a mild, non-abrasive cleaner and a soft cloth or sponge.
- Tank Cleaning: Periodically rinse both the fresh water and holding tanks thoroughly with clean water. For deeper cleaning, use a specialized portable toilet tank cleaner.
- Seal Maintenance: Inspect the rubber seals on the waste valve and pour spout for wear or damage. Lubricate seals with a silicone-based lubricant to maintain flexibility and prevent leaks.
- Storage: When storing the toilet for extended periods, ensure both tanks are completely empty and clean. Store in a dry, cool place.
- Winterization: In freezing conditions, ensure all water is drained from both tanks to prevent damage from ice expansion.
