Step 1: Locate the Chemical Toilet Cassette Compartment

Upon parking your caravan on-site and ensuring it’s level, locate the external compartment where the toilet cassette is housed. This is usually a lockable hatch on the outside of the caravan, close to where the bathroom is positioned inside.


 

Step 2: Remove the Cassette

Unlock the compartment and gently slide out the cassette. Most cassettes have a handle and wheels, making them easy to transport. Check that the cassette is empty before proceeding.


Important Note: Ensure the toilet slide valve inside the caravan is closed before attempting to remove the cassette. The slide valve prevents the cassette from being removed if it is left open, as this could cause spills or damage to the system when its full.

Step 3: Prepare the Cassette for Use

Before reinstalling the cassette, you need to prepare it:


Add Chemical Toilet Fluid: Open the spout cap and pour the recommended amount of blue or green chemical toilet fluid into the cassette. Blue fluid is designed to break down waste and neutralise odours effectively, while green fluid offers an eco-friendly alternative suitable for disposal in natural environments. Always follow the manufacturer’s instructions for the correct dosage.


Add a Small Amount of Water: Pour approximately half a litre of water into the cassette to activate the toilet chemical.

Step 4: Reinstall the Cassette

Carefully slide the prepared cassette back into its compartment. Ensure it clicks into place securely. Close and lock the external hatch to prevent any accidental movement during use.


 

Step 5: Fill the Flush Tank (if applicable)

Many caravans have a separate flush tank for the toilet. If your caravan has one, locate the filler cap, usually outside near the cassette compartment. Open the cap and add the measured dose of pink flush fluid and then fill with fresh water. This ensures the bowl is kept clean and fresh-smelling.


 

Step 6: Test the System

Step inside the caravan and test the toilet. Start by opening the toilet’s slide valve, then press the flush button or operate the pump handle to check that everything is functioning properly. If your system includes a status display, verify that there are no active errors. Once you've confirmed everything is working as it should, close the toilet slide valve to prevent any odours. And that's it – you're done!

 

By following these steps, you’ll find that setting up a caravan cassette toilet is straightforward. Proper preparation will ensure a hassle-free experience, leaving you more time to enjoy your caravanning adventure.
