Formation of ice and mist in extreme weather conditions
It is only in the most extreme conditions that icing and misting of
window glass are likely to be a problem, such as in torrential rain or
severe cold coupled with high relative humidity, or when passengers
are perspiring heavily or wearing wet clothes. The following mea-
sures are recommended if such problems should occur:
1 Select and set the temperature to 70°F (21°C)
2 Select . If this is not enough...
3 Increase the fan speed. If this is not enough...
4 Select a higher temperature.
