3.2
NOTE: Condensation can be reduced by keeping all doors and windows closed during
air-conditioner operation, preventing humid air from entering the vehicle. The likelihood of
condensation on the air distribution unit can be reduced by ensuring that the caravan is properly
sealed, preventing entry of moisture laden air.
