1. Activate the fan by preselecting 1-LOW, 2-MEDIUM,
or 3-HIGH, on the fan-blade speed switch.
2. On the wall control, press the RAISE/LOWER switch
pad. Select and press the RAISE position until the
vent lid reaches the desired height, then release the
switch pad. At full-open, the vent fan lift motor will
stall; release the switch pad immediately.
3. Select and press the LOWER position until the lid
lowers to the desired height, then release the switch
pad. At fully closed, the vent fan lift motor will stall;
release the switch pad immediately.
4. When the fan is equipped with a fan blade motor-
reversing switch, preselect either OUT or IN on
the reversing switch; the center position is OFF
(neutral position). As the vent lid opens and reaches
approximately 4 in. (102 mm), the fan blade turns
on to the preselected speed and direction. See
"Operating the Reverse Switch" on page 15.
I OUT (exhaust mode) pulls fresh air in through a
slightly open window or door while expelling
hot, stale, dusty air out to the roof area. IN (intake
mode) draws air into the coach from the roof area
and effectively pressurizes the coach if all windows,
doors and other vents are closed.

5. When the lid closes, the fan motor automatically
turns OFF. Any time you wish to reverse the fan blade
motor while the system is in operation, select the
center OFF (neutral) position and allow the fan blade
to stop completely. Once stopped, you may safely
select the opposite direction to restart the motor.
6. When the fan is equipped with a built-in thermostat,
preselect a comfort setting from deep blue to deep red
on the thermostat dial (22 °F to 123 °F; –6 °C to 51 °C).
The fan motor will turn ON or OFF, based on the
interior ambient temperature when compared to the
thermostat setting. When the thermostat temperature
is "satisfied," the fan motor will turn OFF and the lid
will stay open. When the thermostat calls for cooling,
the fan blade motor will activate automatically. The lid
must be open at least 4 in. (102 mm) and OUT or IN
must be selected (not the center OFF position). The
ON/OFF switch on the wall control next to the RAISE/
LOWER switch must be in the ON position before the
thermostat can activate the fan blade.
