ENTILATION
The three speed (1-low, 2-medium or 3-high)
12-volt DC ceiling ventilation fan (or powered
roof vent) in the commode area allows fresh
air to circulate through the RV. The fan blade
activates when the vent lid is opened
approximately 2".
Fig. 8.24 Typical exterior ventilation fan
Placing a vent cover over the ventilation fan
or using a foam filter is not recommended.
This
greatly
restricts
accumulation of dust and increased sound
levels.
Do not leave the ventilation fan in active
mode or open while the RV is stored or
unattended for extended periods of time. High
winds,
other
unusual
obstructions may prevent the dome from
closing, resulting in leakage that could cause
serious non-warrantable damage.
Rain sensor option
Activate the Fantastic Fan using the portable
radio frequency handheld remote. With the
automatic mode, you select your comfort
setting and the blades will automatically turn
ON/OFF, increase or decrease speed to
maintain your temperature choice. Manual
mode allows you to select OFF or different fan
blade speed settings.
The vent is equipped with a reversible airflow
switch (In or Out air flow), and a rain sensor.

CAMPING & OPERATING
The built in rain sensor closes the dome and
turns off the fan blade when the sensor

and a back up manual dome open/close knob
are also provided.

Maintenance
Periodically check for accumulated debris. If
found, remove the vent screen and fan
blades, and wash gently with window cleaner,
or non-abrasive dish soap and warm water.
Reinstall the vent screen and fan blades
when clean and dry. Do not use the
ventilation fan without properly installed vent
screen and fan blades.
