Important nQtes
The air conditioner must be operated for a
short period at least once a month so that
the seals and bearings of the compressor as
well
as
the expansion valve are lubricated.
This is especially important during the cold
season when the air conditioner is not re-
quired.
To do so, set the temperature selector
switch to maximum cooling temperature (all
the way to the left) and open the centre
vent.
Should the air conditioner become defective,
e.g.
if there is no cold air despite the system
being switched
on,
switch the air conditioner
off and proceed immediately to an Official
Porsche
Centre.

Blower Switch
The air volume can be regulated by turning the
blower switch from setting 1 to
4.
To provide air circulation even when your
Porsche is standing still or at low speeds, the
blower fan runs at low speed even when the
switch is in position
0.

Defroster Switch
Since
the heating effect is dependent on the
coolant temperature, full heating performance is
obtained only when the engine has reached nor-
mal
operating temperature.
To achieve optimum
defrosting,
close the centre vent entirely (slide
lever D all the way to the top). Then press the
defroster button
-
warning lamp comes on
.
Irre-
spective of
the positions
of the uper and lower
levers, the temperature selector switch and the
blower switch, the system is automatically set to
maximum heating
power,
blower speed 4, and
the entire air flow is directed to the windscreen
and side vents
.
In vehicles fitted with air conditioning the com-
pressor is automatically switched on to dry the
air when the temperatre is above
oo
c.
The
centre vents close
automatically.

R ecirculating
Air Switch
By pressing the air recirculating switch you can
prevent unpleasant-smelling outside air
(e.g.
ex-
haust fumes from vehicles
in
front)
from
enter-
ing the
vehicle.
The fresh air supply is cut off
and only the air inside the vehicle is
circulated.
Recirculating air mode may only be used for a
brief period of time since otherwise the
.
window
will mist
up.
