➤ Turn the three-speed knob to the desired speed (0-OFF, 1-LOW, 2-MEDIUM, or 3-HIGH) .
➤ Select UP to raise the dome lid or DOWN to close the lid from the mini-rocker switch located near the lift
motor .
➤ When equipped with a fan blade ON/OFF switch (Model 3300), select ON or OFF . When a fan is equipped
with a fan blade motor-reversing switch (Model 3350), preselect either OUT, IN, or the center OFF position
on the switch . As the dome opens and reaches approximately 4", the fan blade turns on to its preselected
speed and direction . 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 .
I
OUT (Exhaust mode) pulls clean fresh air in through a slightly open window or door while expelling
hot, stale, stuffy 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 .
➤ These two models are equipped with a built-in thermostat . Preselect a comfort setting from deep blue to
deep red on the thermostat dial (22 °F– 123 °F; –6 °C– 51 °C) . The fan motor will turn ON or OFF, based on
the interior ambient temperature 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 automatically activates . The lid must be open at least 4" and OUT or IN must be selected
and not the center OFF position (Model 3350) . The ON/OFF switch on the fan must be in the ON position
(Model 3300) before the thermostat can activate the fan blade .
➤ Both models are equipped with a rain sensor . When the lid is open and moisture contacts the sensor, the
lid closes and disengages the fan blade motor . When the rain sensor dries, it will not automatically re-open
the lid . Manually opening the lid by using the lift-motor knob will bypass the rain sensor with fan operation,
reverting to the setting prior to the sensor's activation . When the rain sensor has been overridden by manually
opening the lid, the rain sensor will become active again once it has dried .
