X The water in the boiler can be heated up to 65 °C. Risk of scalding!
Z When the vehicle is not being used, switch off and drain the boiler.
Z Never use boiler when empty.
Z If the boiler is not being used, empty it if there is any risk of frost.
Z Only operate the boiler with the maximum temperature setting if you require a
large quantity of warm water. This protects the boiler against the build-up of
limescale.
Z Dethleffs recommends that you do not use the water from the boiler as drinking
water.

gases from the boiler can escape into the awning area. Danger of suffocation!
Make sure the area is sufficiently ventilated.
