Setup
- Separate the Tanks: Disengage the latches on both sides of the toilet to separate the upper and lower sections. Lift the upper section off the lower section.

- Fill Fresh Water Tank: Open the fresh water fill cap on the upper section. Fill the tank with clean water. Close the cap securely.

Figure 4: Illustrates the process of adding fresh water to the upper tank through the designated fill opening.
- Add Waste Tank Chemical: On the lower section, rotate the pour-out spout upwards. Add the recommended amount of waste tank chemical (e.g., Thetford Green) directly into the waste tank opening. Add a small amount of water (approximately 1 cup) to ensure the chemical is distributed. Close the pour-out spout.

- Reassemble: Carefully place the upper section back onto the lower section, ensuring the latches engage securely.
- Install Batteries (for electric flush): If your model features a battery-powered flush, locate the battery compartment (typically behind the seat) and insert the required batteries according to polarity markings.
Operation
- Using the Toilet: Ensure the waste tank valve (blade handle) is closed before use.
- Flushing: After use, open the waste tank valve by sliding the blade handle. Press the flush button (for electric flush models) or operate the manual pump (if applicable) to rinse the bowl. Close the waste tank valve completely after flushing to prevent odors. The fresh water tank level indicator is located near the flush mechanism.

Maintenance
- Monitoring Waste Tank Level: The waste tank has a level indicator to show when it is nearing full. Empty the tank before it becomes completely full.
- Emptying the Waste Tank:
- Separate the upper and lower sections as described in the Setup section.
- Carry the lower section to an approved disposal site (e.g., RV dump station, standard toilet).
- Rotate the pour-out spout upwards.
- Press the air vent button while emptying to ensure a smooth flow and prevent splashing.
- Rinse the waste tank thoroughly with water after emptying. You may add a small amount of fresh water and shake the tank to clean it.
- Close the pour-out spout and reassemble the toilet.

- Cleaning: Clean the toilet regularly with non-abrasive cleaners. Avoid harsh chemicals that can damage plastic components or seals.
- Winterization: If storing in freezing temperatures, ensure both fresh water and waste tanks are completely empty and dry to prevent damage from ice expansion.
Troubleshooting
- Odor Issues: Ensure the waste tank valve is fully closed after each use. Verify that the correct amount of waste tank chemical is used. Clean the toilet thoroughly.
- Flush Not Working (Electric Models): Check battery levels and replace if necessary. Ensure no obstructions are present in the flush mechanism.
- Leaking: Check that the upper and lower sections are securely latched. Inspect seals for damage or debris and clean if necessary.
- Slow Emptying: Ensure the air vent button is pressed during emptying to allow air to enter the tank.
