Air distribution is achieved by means of a series of orientable out-
lets (5) with adjustable capacity for the inner flow and for the flow
that has the function to defog the windows.
IMPORTANT
☞
•
At the beginning of the hot season and before using the air
conditioning, clean the suction filters (see “4.7.1.b CAB AIR
FILTER” and “4.7.1.c RECIRCULATION FILTER”).
•
Before using the air conditioning, interrupt the circulation
of hot water in the engine by rotating the tap (6) positioned
in the engine compartment clockwise.
The air conditioner is set in operation with the switch (1) posi-
tioned on the left console.
After starting the air conditioner (switch led on), turn the knob (3)
completely anticlockwise and adjust the ventilation flow with the
switch (2).
CAUTION
•
Even in the period during which the air conditioner is not
used, operate the compressor at low speed for approxi-
mately 3-5 minutes at least once a month. This operation
keeps all the moving parts of the compressor lubricated.
