NB!
In snow storms or other especially unfavourable
weather, furnishings should be protected
against damp or snow penetrating through the
motorhome’s fixed ventilation.
FIXED VENTILATION
The motorhome’s ventilation satisfies standard EN 721 on
safety requirements for ventilation in recreational vehicles.
The ventilation has been tested for the number of people
and the uses for which the motorhome is intended.
Thus, the fixed ventilation must not be altered!
The air in the motorhome is ventilated to the outside by:
• fixed ventilators in the roof (Elektrolux ventilators),
• ventilating roof hatches,
• kitchen ventilation.
Ensure that the motorhome’s fixed ventilation is not
obstructed . In winter, roof hatches and ventilators must be
kept free from snow.
In especially unfavourable weather, moisture can
penetrate the fixed ventilation in the roof hatches.
Protect the motorhome’s furnishings.
VENTILATION
CONDENSATION
Condensation occurs naturally when warm air hits a cold
surface (e.g. the interior side of a window and pane surfa -
ces inside double glazing).
Condensation formation is affected by a number of factors,
for example:
• The temperature difference between inside the motor
-
home and outside the window.
• The weather. High air humidity or mist means that the
air inside the motorhome contains more water.
• Number of people (or pets) in the motorhome.
• Activities in the motorhome (e.g. cooking).
If the weather and activities are such that there is a lot of
condensation, the latter can be combated by:
• Airing the motorhome so that the air inside contains as
little water as possible.
For efficient airing, open the roof hatch.
Ensure that the motorhome’s fixed ventilation is not
impeded (e.g. no cushions or loads obstructing ventila -
tion routes).
• Raise the temperature in the motorhome.
Raising the temperature in the motorhome increases
air flow in the ventilation. Furthermore, the interior
side of glazing warms up, which also further combats
condensation.
When condensation forms on cold surfaces, it should be
wiped away.
The motorhome’s windows are made of an acrylic plastic.
Water vapour can slowly migrate through the acrylic
plastic and lead to condensation forming between the pa -
nes. This is natural and the condensation disappears after
a while when it has migrated further.
The kitchen fan.
ROOF HATCHES
Roof hatches and roof lights must be closed and bolted
throughout travel. Blackout curtains and mosquito screens
must be fully raised throughout travel because they can be
damaged by vibration and increased ventilation.
KITCHEN VENTILATION
Each Travel Master has a motor-driven extractor fan fitted
to the ceiling. The switch is on the fan panel below the
crockery cupboard. The switch for kitchen lighting is also
here.
The fan filter
This filter absorbs the fat in cooking fumes and must be
cleaned from time to time. Clearly enough, the frequency
depends on the foods that are cooked and how often the
fan is used. Wait until the suction generated by the fan
lessens.
Clean with hot water to which some synthetic cleaning
agent has been added.
The fan impeller
Fan impeller and motor are accessed for cleaning by
unscrewing the connection to the ceiling.
