DESCRIPTION AND OPERATION
Through-flow ventilation
Through-flow ventilation is achieved by means of
one-way air extraction vents incorporated in both rear
quarter body panels. The vents open and close
automatically dependent upon the heating and
ventilation unit control settings and the volume of air
entering the vehicle.
Heating and ventilation unit, controls
The Heating and Ventilation Unit is centrally located
and concealed by the dash assembly. When air
conditioning is fitted, an evaporator is mounted in the
heater unit forward of the heater matrix.
The dash mounted central controls are used to
operate both systems. A single switch controls the air
conditioning unit when fitted.
