Rectorseal 96120 Primary Pan Condensate Sensor

Product Description

The RECTORSEAL 96120 is a solid-state primary pan condensate sensor designed for residential and light commercial HVAC condensate management. Sold under the AquaGuard AG-3125E designation, it uses probe-based water detection technology instead of a float switch, eliminating the moving parts that are prone to clogging or mechanical failure. The sensor operates at 5 amps and 24 volts AC, includes a built-in time delay to reduce nuisance trips, and features a water detection LED indicator for fast visual confirmation of a wet condition. A compact, waterproof housing keeps the low-profile design unobtrusive in tight primary drain pan installations. UL 508 listed.

This sensor is installed in the primary condensate drain pan of split-system air conditioners, heat pumps, and air handlers where overflow protection is required. It is suited for installations where float switch performance has been unreliable due to algae growth, debris, or restricted pan geometry. The 6-foot probe wire and 6-foot sensor wire provide routing flexibility in equipment closets, attic installations, and platform-mounted units. HVAC technicians typically wire this sensor into the low-voltage control circuit to shut down the system on a wet-pan condition before overflow damage occurs.

Key Features

• Solid-state design with no moving parts — eliminates clogging risk common with float switches
• Built-in time delay prevents nuisance shutdowns from momentary condensate splashing
• 5 amp, 24-volt AC rating for direct integration into low-voltage HVAC control circuits
• Water detection LED provides immediate visual confirmation of a wet-pan event
• Compact waterproof housing suits tight or restricted primary drain pan installations
• 6 feet of probe wire and 6 feet of sensor wire included for flexible field routing
• UL 508 listed solid-state construction

Compatibility

Designed as an OEM-style replacement or new-installation primary pan condensate sensor for residential and light commercial HVAC split systems, heat pumps, and air handlers equipped with 24-volt AC low-voltage control circuits.

Installation Notes

Installation should be performed by a qualified HVAC technician familiar with low-voltage control wiring. Disconnect power to the air handler or furnace at the disconnect or breaker before wiring the sensor into the control circuit. Verify that the probe tip is positioned correctly in the primary drain pan at the desired water-level detection height. Follow all applicable local mechanical and electrical codes during installation.
