Attaching the Sensor
The black sensor on the monitor slides into the slot on the dial, and clicks into place.
If you have an underground tank and the fill valve is blocking the attachment of the sensor, as shown in the photo below, please call your propane supplier to remove the dial.
Your supplier will need to attach the sensor while the dial is removed from tank, and re-attach your dial. Please reference this article for removing the dial: Replacing Your Dial
