CoolGuard FS2 Horizontal Float Switch for HVAC Condensate Overflow Protection, 24VAC Safety Switch

Product Description 

The CoolGuard FS2 Float Switch helps protect HVAC systems from costly water damage by automatically shutting down the equipment when a clogged condensate drain causes water levels to rise. Designed for horizontal installation at the primary drain pan auxiliary outlet, the FS2 includes an adapter, bushing, and cap for quick installation and reliable condensate overflow protection.

 

Protecting your HVAC system from condensate overflow is one of the easiest ways to avoid expensive water damage repairs. The CoolGuard FS2 Float Switch continuously monitors condensate levels and automatically shuts down your air conditioner or heat pump if the drain becomes blocked.

Unlike inline float switches, the FS2 is specifically designed for horizontal installation where the primary drain pan connects to the auxiliary drain outlet. This location allows the switch to quickly detect rising water levels before overflow can damage the air handler, insulation, ceilings, drywall, or flooring.

Installation is straightforward thanks to the included adapter, bushing, and cap, making the FS2 an excellent choice for new HVAC installations, system replacements, and preventative maintenance upgrades.

The removable inspection cap allows technicians and homeowners to quickly inspect and clean the switch without complicated disassembly, helping keep the condensate drain system operating efficiently year after year.

Compatible with 24VAC Class 2 thermostat circuits, the CoolGuard FS2 is suitable for residential and light commercial HVAC systems.
