3. PREPARATION
1. Remove the unit from the box and inspect for damage. Installation hardware is located in a plastic bag
along with this guide, on top of the filler.
2. Put the unit down on a protected surface.
3. Refer to your local building code to determine the required airflow.
4. Open the unit’s door to access the settings on the electrical compartment cover.
5. Adjust the settings according to the required airflow. The first number around the Airflow Range
adjustment is the Low Range CFM value (30-100 CFM), and the second number is the High Range
CFM value (110-180 CFM). Use a small flat blade screwdriver to switch from Low Range to High
range, and to adjust the CFM value.
