Auto-Trail Toilets & Sanitation

Pull the safety catch upward to release the waste-holding tank, then slide it out, tipping it slightly as it comes free. Stand it upright with the emptying spout facing up, unscrew the cap, and pour in the recommended amount of Thetford toilet fluid plus about 2 litres of water to cover the base. Screw the cap back on, return the spout to its stored position, then slot the tank back in through the access door and re-secure the safety catch.
