Inductive water level sensor
This water level sensor is to be glued under the spa shell at the water line, and detects the presence or absence of water in the spa. It works with Balboa Classic Line systems, among others.
This sensor is set at the factory, but if the detection does not work properly, it is equipped with an adjustment screw behind the sticker. Unscrew to increase the sensitivity of the sensor, or screw to lower it.
A red LED lights up when the sensor detects water.
Installation
The sensor is not self-adhesive, so you'll need to glue it under the shell with a small amount of mastic and possibly an adhesive on top. If insulation is used under the spa shell, it should be scraped to obtain a thin, fairly smooth wall.
