The optional high-volume roof vent system is designed to quickly exhaust stale, hot air
and draw in fresh air. It’s great to use when the outside temperature really doesn’t call
for air conditioning, but heat has built up in your coach.
OPERATING INSTRUCTIONS:
1. Rotate 3-speed switch to desired position, 0-off, 1, 2, and 3. The 3-speed switch
must be set at 1, 2 or 3 to activate appliance.
2. Rotate thermostat knob toward 40° (cooler) until dome begins operating.
3. When equipped with reverse switch, there is a neutral (off) position. Fan motor will
not operate when in/out switch is in its center "off' position. The dome will, however,
operate up and down automatically as long as the 3-speed switch remains on.
4. To determine desired temperature setting:
a. Use the wall thermometer on furnace thermostat, or any interior
temperature indicator.
b. Operate fan until interior comfort level is achieved. Rotate thermostat
knob toward 110' symbol on label until dome begins closing. You now
have the location for normal setting.
The thermostat sensor is calibrated approximately 4°. This minimizes rapid recycling
of the unit, once desired temperature level is achieved.
5. The rain sensor built into your fan will prevent excessive rain from entering coach
through the open dome. Maintain a setting above (to the right of) "rain override"
zone and the dome will close when the sensor becomes wet.
WARNING : Do not leave coach unattended with thermostat knob set in
the “rain override” zone.
6. A rain sensor override is built into this system so you can operate your fan during
light to moderate rains. When sensor is wet, rotate fan thermostat knob to coolest
position to override sensor. Dome will open and fan motor will start. When sensor
has completely dried, rotate thermostat knob back to desired setting for automatic
operation.
7. To close dome in extremely hot conditions, rotate thermostat knob right, past 110’
symbol to off. Dome will come down.
8. Always allow dome to completely cycle up and down. If dome “hangs up” in partially
open/close position, rotate thermostat knob to extreme right and then left position
allowing complete cycles down and up. Now reset to original comfort level.
9. When vehicle is in storage, rotate thermostat knob to right (off), after dome closes,
turn 3 speed switch to “O” (off).
CLEANING INSTRUCTIONS:
1) Turn fan motor OFF.
2) Remove 8 painted flathead Philips screws around perimeter of screen
insert only.
3) Clean screen with soap & water solution and reinstall.
