HEATING, VENTILATION AND AIR
CONDITIONING CONTINUED

DEF distributes outside air through the windshield defroster ducts. It can be used to
clear ice or fog from the windshield. If the temperature is about 50 degrees farenheit (10
degrees celsius) or higher, the air conditioner will automatically dehumidify the drivers
cab air to reduce fogging.
OPERATING TIPS
In humid weather, select defroster before driving. This will reduce fogging on your
windshield. After a few minutes, select any desired position. To prevent humidity
buildup inside the motorhomes driver's cab area, do not drive with the climate control
system in the "OFF" position.
Remove any snow, ice or leaves from the air intake area located at the bottom of the
windshield. If the motorhome has been parked with the windows closed during hot
weather, the air conditioning ill do a much faster job of cooling if you drive for 2 or 3
minutes with the drivers and passengers door windows open. This will force most of the
hot, stale air out of the motorhomes driver's cab area. Then operate your air conditioner
as you normally would.
Do not place objects over the defroster outlets. These objects can block airflow and
reduce your ability to see through the windshield. Also, avoid placing small objects on
top of your instrument panel. These objects can fall down into the defroster outlets,
block airflow and possibly damage the climate control system.
