RectorSeal 96143 AquaGuard AG-4200E Electronic Condensate Management System Water Sensor

The RectorSeal AquaGuard AG-4200E (96143) is a multipurpose electronic condensate overflow sensor that delivers a complete condensate management solution for HVAC auxiliary drain pan installations. Engineered with advanced solid-state water sensing technology, this sensor detects rising condensate levels and interrupts the 24 VAC control circuit to shut down the system before overflow damage can occur — no floats, no moving parts.

Designed as a complete kit, the AG-4200E is compatible with RectorSeal's Goliath, Goliath Furnace, Goliath Value Series, and Titan flexible secondary drain pans, making it a versatile choice for both residential and light commercial HVAC applications.

Key Features:

• Solid-State Electronic Sensor — No moving parts for maximum reliability and long service life
• 24 VAC / 5 Amp Rating — Integrates directly into standard low-voltage HVAC control circuits
• Configurable Output — Switch can be wired normally open or normally closed to suit system requirements
• 1/4" Trigger Depth — Responds to water quickly; shallower trigger depth than the magnetic AG-4000M series (1/2")
• Water Detection LED Indicator — Provides immediate visual confirmation of water detection
• Up to 60-Second Time Delay — Adjustable on-delay helps prevent nuisance trips
• 4th Wire Alarm Output — Open circuit wire option supports external alarms, controllers, or multifunction digital power management systems
• Adjustable Height Mount — Flexible positioning to suit different drain pan depths
• 6 ft of 18 AWG Control Wire — Pre-attached for quick field wiring
• 3/4" MPT PVC Drain Adapter — Redesigned threaded adapter included for easy drain port connection
• Compact Waterproof Design — Polystyrene housing sealed for high-moisture environments
• 14 Vibration Isolators Included — Required for Goliath/Spartan and Titan pan installations using Goliath risers
• UL 508 Approved — Meets industry safety standards

Measuring 4-5/8" L x 4-3/8" W x 2-7/8" H, the AG-4200E is compact enough for tight installations while delivering professional-grade condensate protection. The kit includes the water sensor, 3/4" MPT PVC adapter, and 14 vibration isolators — everything needed for a complete installation.
