5. Operating Instructions
After successful installation, restore power to the unit at the service panel.
5.1 Fan Operation
The exhaust fan operates at 110 Cubic Feet Per Minute (CFM) with a low noise level of 1.2 Sones. It is controlled via a standard wall switch (not included) connected during installation. Turn the switch ON to activate the fan and OFF to deactivate it.
5.2 LED Light Operation and Color Temperature Selection
The integrated LED light provides 800 lumens of illumination and offers three selectable color temperatures: 3000K (Warm White), 4000K (Natural White), and 5000K (Cool White).
- To cycle through the color temperatures, use the wall switch connected to the light circuit.
- Turn the light switch ON. The light will illuminate at the last selected color temperature.
- To change the color temperature, quickly turn the light switch OFF and then ON again within 1-2 seconds. The light will cycle to the next color temperature.
- Repeat this process until your desired color temperature is selected. The fan will remember the last setting.
