Recirculation
•
In recirculation mode, air inside
the vehicle is circulated again
and again. In Fresh Air mode,
air is taken from atmosphere
and circulated in the vehicle.
Recirculation mode can be used
•
While driving in dusty condition
•
To avoid traffic pollution
•
To get quick cooling/heating as
required.
Whenever discomfort is felt switch
to fresh air circulation mode.
NOTICE
•
We strongly recommend AC to
be used in recirculation mode
for better cooling.
•
Use fresh Air mode only when
discomfort is felt.
•
The AC can be switched `ON'
only if the blower is 'ON' and
engine is running. When AC is
switched 'ON' engine idling
RPM increases marginally, to
adjust to the AC compressor
load. When desired
temperature is achieved AC
trips 'OFF' automatically.
•
The AC compressor is
switched 'OFF' automatically
when engine gets overheated.
The AC is automatically
switched 'ON' when the engine
cools down.
Ventilator :
The air flow can be adjusted
continuously with the rotary control
knob at the vents on the dash board.
The air vents can be adjusted
upward and downward.
NOTICE
Refrigerant charged in the air
conditioning circuit has been
identified on the label over front
body member. Use only
refrigerant as given in the label
for topping up or recharge, i.e. do
not charge the vehicle with some
other refrigerant than the existing
refrigerant. Always use R134a
(Non CFC) refrigerant.
Fresh air is taken from the grill
opening provided on the fire wall
under the front hood at base of
windshield glass outside the
vehicle. Keep these openings
clear and free.
