Vents are provided in the motorhome to circulate fresh air and exhaust odors. The
power vent includes a 12 VDC powered fan. A hand crank controls opening and
closing and adjustment of the vent cover, while a push button turns the exhaust fan
ON and OFF. Make sure to turn the fan OFF before closing the vent. Also be sure to
remove any debris that falls into the vent that may restrict operation. It is extremely
important that you use the fans and vent every time you use the shower or tub to
eliminate excess condensation.
Note: For best results, close all other roof vents and open one
window, or door the greatest distance from the exhaust vent.
Note: The dome must be open prior to operating the fan motor.
