How do I prepare the Truma S heater for the travel season?

We recommend that you clean the Truma S heater before starting your holiday.

  • Remove the cover from the S heater.
  • Remove the dust that has accumulated on the heat exchanger or on the base plate.
  • Remove dust on the fan wheel of the Trumavent carefully with a paintbrush or a small brush.
  • Also check whether the exhaust cowl is damaged or contaminated with leaves, for example.
  • Insert the battery in the auto ignitor – if you do not hear ignition sparks or if they are more than a second apart, replace the battery. When replacing the battery, the heater must be switched off. Use only temperature-resistant (+70 °C) leakproof AA batteries. Other batteries may cause malfunctions.
