Heater and ventilation system
Fresh-air fan switch
Air-flow
Pushed right in - closed
FLOOR = Air to front seat floor
Interm. pos. - full output
DEFR = Air to windscreen
Fully out - half output and to rear seat floor
The heating and ventilation system of the car is operated as shown above.
Air is sucked in by the fan and then passes through a heater element
to a distributing chamber where it is distributed to the floor and wind-
screen by means of the controls. NOTE: During normal condition there
is sufficient air-flow due to the fact of the overpressure at the air inlet
of the vehicle. If greater quantities of air are required, use the fan.
The heater element is connected with a thermostat which keeps the tem-
perature constant. When the temperature control is moved, there will be
a slight delay before the heater element adjusts itself to the desired
temperature.
The illustration shows the air duct to
the rear seat and the air distribution
in the vehicle when both the "FLOOR"
and "DEFR" controls are used.
Misting on the windows
During cold or damp weather mist can
easily form on the windows, particu-
larly with a full number of passengers.
The best way of getting rid of this or
to avoid it altogether is to open the
ventilation windows partly or fully and
to set the fan and defroster controls
at max. output.
