The AG-9300 Series are electronic condensate drain sensors for mini-split or duct-free systems. The AG-9300 Series features the AG-9300-U, which is the first universal condensate water sensor developed to be compatible with all major manufacturers' mini-split or duct-free systems currently on the market in addition to specifically developed electronic condensate drain sensors with exclusive wire harness connectors for Mitsubishi, LG, and Comfort Star units. Each system continuously monitors any condensate overflow in the primary drain pan and automatically shuts off the mini-split or duct-free system and activates an audible alarm if any overflow is detected. The AG-9300 Series also provides contractors with the flexibility to meet multiple code requirements being enforced in many states today including International Mechanical Code 307.2.3.1, which states On down flow 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.
