Test
• Press the test button for at least 4 seconds until the alarm
goes off. The alarm goes off when the electronic system is
working. It will stop as soon as you let go of the test button.
Test the smoke detector every time the battery has been changed.
Batteries should never be thrown in the container for normal
household waste. Always return used batteries to a shop that
sells batteries or take them to a designated collection point.

12.5 Airing

For a comfortable climate inside the van, there must be sufficient
ventilation. You will notice an increased amount of condensation
inside the van on cooler days or after it has not been used for a
prolonged period of time. This condensation may be particularly
heavy on single-glazed windows. Damp spots are sometimes
even noticeable on furniture surfaces, the inner side of outside
walls, and often also in cupboards. Furthermore, such dampness
can cause mould to build up, which then rapidly spreads to other
surfaces. This situation not only impairs your sense of well-being,
but can also lead to damaged components. This condensation is
generally caused by the air in the room. One of the properties of
air is that it can absorb water. The hotter the air is, the more water
it can absorb (relative humidity). If air that is totally saturated
with water vapour cools down and reaches its saturation point,
it gives off part of the water in the form of condensation. This
is also known as a "cold bridge". However, condensation occurs
primarily when there is little airflow due to structural conditions
or insufficient airing.
Condensation is caused by
- insufficient volume inside the van
- breathing and perspiration of the passengers
- bringing in damp clothing
- operating a gas cooker
- Showering, washing or doing the washing-up with very
warm or hot water
While sleeping, a person loses about one litre of water per night
through the pores of their skin and breathing. The additional water
vapour in the air must be discharged from the recreational vehicle
by airing it sufficiently at regular intervals. An air change of 0.5
to 1 ACH (Air change per hour) is required if only for reasons of
hygiene to ensure that the level of toxic substances and odorous
pollutants in the air in the room remains low.
