Body
Knob, ventilation hatch
In some caravans, the roof hatch in the middle of the
caravan has been replaced with a skylight. The skylight
can be opened and is fitted with a mosquito net and a
roller-blind, just like the roof hatch. See also the section
”Roller-blind in roof hatch and skylight” on page 29.
Before using the caravan, ensure that the
fresh air intakes, roof hatches, skylights and
ventlators are completely free from snow and
other things that can obstruct the circulation.
∆
It is dangerous to remain in the caravan when
there are naked flames without having suf-
ficient ventilation.
∆
Roof hatches, skylights and ventilators
Roof hatches and watertight ventilators are included in
the ventilation system and are intended to release air. All
roof hatches can be opened and are fitted with mosquito
nets. The roof hatch in the middle of the caravan is also
fitted with a blackout curtain.
Ventilators Roof hatches and skylights
Clean dirt and dust from the air inlets under
the floor and the ventilators on the roof at
least once a year.
∆
Do not flush water through the ventilation
grilles when washing the caravan.
∆
Ventilation hatches
Some caravans are equipped with ventilation hatches for
extra ventilation. The number of hatches varies depending
on the model.
Ventilation grilles can be found on the outside of the
caravan. Do not flush water through these grilles when
washing the caravan.
The ventilation hatch is opened with the knob located in
the middle of the hatch.
In unfavourable weather conditions in the winter, there is
a risk of snow penetrating through the roof hatch’s ventila-
tion. You must therefore remember to protect the caravan’s
fixtures and fittings and its upholstery, particularly when the
caravan is due to be pitched for an extended period.
