For Mitsubishi Ductless Mini-Split Systems

The AquaGuard AG-9300-MIT is the first condensate sensor designed to fit all Mitsubishi Electric residential and commercial systems. This new sensor features exclusive wire harness connectors that were designed in close collaboration between Mitsubishi Electric and RectorSeal.

The AG-9300-MIT provides electronic condensate overflow protection for drain pans in all Mr. Slim® and CITY MULTI® indoor units: MFZ, MS, MSY/Z, SEZ, SLZ, PCA/PCFY, PDFY, PEA/PEA(D)/PEFY, PKA/PKFY, PLA, PLKA/PLFY, PMFY, and PVFY.

Mini-Split-CutAwayThe AG-9300-MIT continuously monitors any condensate overflow in the primary drain pan and automatically shuts off the Ductless Mini-split systems and activates an audible alarm when any overflow is detected. When activated, a thermistor error code will be displayed indicating a fault must be resolved before the unit will restart.

The AG-9300-MIT also provides contractors with the flexibility to meet multiple code requirements being enforced in many states today including International Mechanical Code 307.2.3.4, which states “A water-level detection device conforming to UL 508 shall be provided that will shut off the equipment served in the event that the primary drain is blocked. The device shall be installed in the primary drain line, the overflow drain line, or in the equipment- supplied drain pan, located at a point higher than the primary drain line connection and below the overflow rim of such pan.”

The AG-9300-MIT eliminates the need for a second, bulky and unsightly secondary drain pan underneath the indoor unit. This revolutionary new product is also a less expensive code compliant option compared to a condensate pump for Mitsubishi Electric Ductless Mini-split systems installations. In addition, the AG-9300-MIT can also be installed with a condensate pump and used as a standalone backup system to provide extra protection in the event of a condensate pump failure.

With a compact control box and probe, the AG-9300-MIT is designed to fit completely inside the Mitsubishi Electric Mr. Slim® and CITY MULTI® indoor units, which provides numerous mounting options inside the unit as well as a clean, quick, and easy professional installation in about five minutes.

The compact control box also features an adhesive pad and exclusive Mitsubishi wire harness connectors that plug directly into the unit’s circuit board.
