➤ Activate the fan by preselecting 1-LOW, 2-MEDIUM or 3-HIGH, on the fan-blade speed switch.
➤ On the wall control, press the RAISE/LOWER switch pad. Select the RAISE position and press it until the
dome (lid) reaches the desired height, then release the switch pad. At full-open, the dome lift motor will
stall; release the switch pad immediately! Select the LOWER position and press it until the lid lowers to
the desired height, then release the pad. At fully closed, the dome lift motor will stall; release the switch pad
immediately!
DAMAGE HAZARD: Continuing to press the RAISE/LOWER pad after the dome is open or
closed will cause damage to the lift system.
➤ When the fan is equipped with a fan blade motor-reversing switch, preselect either OUT or IN on the switch;
the center position is OFF (neutral position). As the dome opens and reaches approximately 4", the fan blade
turns on to the preselected speed.
➤ 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, select the opposite direction and restart the motor.

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.
➤ 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 – 123 °F; –6 °C – 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" and OUT or IN must be selected
(not the center OFF position). The ON/OFF switch on the wall controller next to the RAISE/LOWER switch
must be in the ON position before the thermostat can activate the fan blade.
