Cab, Instruments and Controls
The fan has two speeds: one applies to re-circulation the other to fresh air. The recirculation
position is suited to quickly de-mist or cool the cab with the air
conditioning, quickly heat the cab, de-frost the windows with the heater and keep
out undesirable odours.
Note:
You are advised to switch on the re-circulation without air conditioning for short
periods only to prevent the air quality inside the cab degrading and moisture
increasing.
Fan speeds with fresh outside air ventilation valve open
Fan speeds with re-circulation valve closed, hardly any supply of
fresh outside air
