Frequently Asked Questions - iNDUS THETFORD

How to connect the toilet to the Thetford app?
Enable Bluetooth on your smartphone and open the iNDUS app. On the toilet control panel, press and hold (at least 5 seconds) both flush buttons until the blue light flashes. In the app, tap Connect to complete pairing.
What to do when a red light appears above an additive cartridge?
The red light indicates the cartridge is empty. Replace it immediately with a new cartridge of the same type (iNDUS GREY, FLUSH or BLACK). Follow the replacement procedure described in the manual: open the slider, remove the empty cartridge, place the cap on the new cartridge and insert it following the order A, B, C.
Can I use any toilet paper?
For optimal performance, use Thetford toilet paper. In an emergency, use thin (single-ply) toilet paper. Never use wet wipes, moist toilet paper or similar products, as they may clog the system.
How to drain the waste water tanks?
Open the service door and take out the discharge device. Unroll the hose and place the nozzle over a drainage grate. Press the knob to open the valve, then press the discharge button on the control panel. Wait for the cycle to finish (blue light off). Close the valve and stow the device.
What to do in case of a clog in the toilet bowl?
Press the valve open/close button to open the bowl. Turn off the power to the central control panel. Then try to unclog the bowl manually. Do not put your fingers in the macerator area when the power is off.
How to prepare the system for winterization?
Remove all additive cartridges and store them frost-free. Empty the black and grey water tanks using winterization mode (press the winterization button instead of the discharge button). Manually drain residual water via the drain valves under the floor. Leave the valves open.
Can I use the system without the app?
The app is required to set up the first use and to get information on additive and tank levels. However, basic functions (flush, discharge) can be used via the control panel even without the app.
What maintenance products to use?
Use exclusively Thetford products: Toilet Bowl Cleaner for the inside of the bowl, Bathroom Cleaner for the exterior, and iNDUS Cleaning & Storage for full system maintenance. Never use household products, as they may damage the seals.
What does a flashing orange light on the toilet control panel mean?
A flashing orange or red light generally indicates a pairing problem with the app. Check the Thetford app notifications for details. If pairing failed, try again following the procedure.
Where can I find spare parts and after-sales service?
Visit www.thetford.com or use the Maintenance section of the Thetford app. To contact an authorized dealer, have the model and serial number (located on the label). Contact details for European centers are in the manual.
