unit
is fitted on the bulkhead beside the battery. The valve is opened (1) by movin
g
the lever towards the battery. Moving the lever away from the battery closes
(2)
the valve.
Air flow (Fig

the
flow of air to the car interior. Turn the knob anti-clockwise from the
'OFF'

ition
to open the
valve,
the valve is fully open when the knob is turned
to
the 'ON '
position.
Booster. Press the lower end of the switch rocker (2) to boost the air flow.
Illumination
The
markings on the
booster switch, the control dial and the position
indicator
on the rotary control knob are illuminated when the panel lamps are switched
on.
Body
Regular
care
of the
body finish is necessary if the new ap
pearance of
the
r
exterior is to be ma intained
agains t the
effects of air pollution, rain, and
mud
.
Wash the
bodywork frequently, using
a
soft
sponge and
plenty of
water con
-
taini
ng car
shampoo.
Large deposits of mu
d must be softe
ned with
water
before
using the sponge.
Smears should be removed by
a second
wash
in
clean
wate
r,
and
with the sponge if
necessary.
When dry,
clean the
surface
of the
car with
a da
mp chamois-leather. In addit ion
to the regular maintenance,
special attention
is requi
red if the
car
is driven in extr
eme
condit ions such
as sea spray
or on
salted
roads.
In these
conditions
and
with
other
forms
of
severe
conta mination
an
add
itional washing operation is necessary which
should include
under-
body hos
ing. Any da
maged
areas should be
immediately
covered with
pa
int
and
a complete
repair
effected as
soon
as
possi
ble.
Before
touching-in light scratches
and ab
ras ions with
paint ,
tho
roughly clean
the
surface. Use pet
rol /white
spirit
(gasoline/hydr
ocarbon so
lvent) to remove
spots
of
grease
or
tar .
Usag
e
By varying the sett
ings
of the air flow control, opening or closing the air distr
i-
bution do
ors,
and ut
ilizing
the booster blower, a wide range of settings can
be
obtained for heating, when the heater
valve
is open, or for ventilating when
the
valve is
shut,
to suit prevailing
conditions.
Bright trim
Never
use an ab
rasive
on
stainles
,
chromium, luminium,
or
plastic
bright
pa
rts
and on no
account
clean them with m ta
l poli
h. Remove
spots of
grease or
tar
with
petrol/white spirit
(gasoline/hydroc
rbon
lvent)
and wash
frequently
with
water
containing car shampoo. Wh
n th
d
irt ha
been
removed polish
with
a clean dry cloth or
chamois-leath er
un
til bright.
Any
slight
tar
nish found on
stainless or plated
components
which have not
received regular
attention
may
be
removed with
chrome cleaner.
An occa ional
application of
light
miner
al
oil or
grease will
help
to
preserve the fini
h, particular
ly during winter when
salt
may
be used on the
roads, but these protectives must
not be appl
ied
to plastic
finishes.
