For vertical configuration units with narrow filter access doors at the bottom, the Filter sensor may not fit behind the filter in the standard position. Use one of these alternative placements.
Option 1: Side Cabinet Mount (Recommended)
Mount the Filter sensor to the inside wall of the cabinet using its built-in magnets.
Remove the filter access door at the bottom of the unit
Remove the air filter from the slot
Attach the Filter sensor to the side of the cabinet above the filter using the built-in magnets
Replace the filter and access door
The sensor does not need to sit directly behind the filter to function properly. Side-mounting keeps it secure, out of the way of the narrow door, and accessible for battery replacement.
Option 2: Filter Sensor Accessory (If Available)
If you have the Filter Sensor Accessory on your truck, this cable-based solution allows the sensor to remain outside the cabinet entirely.
Push the accessory pin through the filter material (following airflow direction)
Connect the pin to the sensor
Route the cable through the filter access opening
Mount the sensor outside on the cabinet using its magnets
The thin cable passes through the narrow opening while the sensor stays outside for easy access.
See Filter Sensor Accessory for detailed installation steps.
