Product overview

An added safety measure that keeps water from pooling and causing internal damage to your air handler isn't something that should be left out of your HVAC setup. With the addition of a CoolGuard FS3 Drain Pan Float Switch, you can relax knowing the inner workings of your system are well-protected against moisture. Designed to automatically detect when the condensate drain is clogged, the CoolGuard Float Switch shuts down the unit to keep the hardware safe from condensate build-up.

Constructed with heavy-duty steel mounting brackets, the CoolGuard Switch secures to the condensate drain pan for a reliable installation. With a design that can support installations that are off-center, you can use the CoolGuard Drain Pan Float Switch on primary or auxiliary drain pans without worrying about the part malfunctioning. The general purpose CoolGuard Switch supports voltage of 24VAC and current of 1.25 amps, allowing use in class 2 thermostat circuits.

Highlights

  • Heavy-duty steel mounting brackets accommodate off-center mounting
  • Works on both primary and auxiliary drain pans
  • Automatically shuts down the air handler upon detecting rising water
  • Rated 24VAC, 1.25A — compatible with Class 2 thermostat circuits
