The AG-9300 is the first condensate water sensor designed specifically for mini-split systems. The entire sensing system is compact enough to fit completely inside of the indoor unit and powered by a lithium ion battery which can last the lifetime of most mini-split systems. The International Mechanical Code 307.2.3.1 states: "On downflow units and all other coils that do not have a secondary drain or provisions to install a secondary or auxiliary drain pan, a water-level monitoring device shall be installed inside the primary drain pan. This device shall shut off the equipment served in the event that the primary drain becomes restricted. Devices installed in the drain line shall not be permitted". Includes mini-split systems.

The AG-9300 is easy to install, in a few simple steps you'll be done.
