High Quality: SS2 Float Switches are made with advanced technology, safe and reliable, with stable performance. Function: The SS2 Float Switch detects clogged air conditioning drains and automatically shuts down the system to prevent water overflow and potential damage to floors, walls, and ceilings. Easy to Clean: The SS2 float switch is removable for convenient cleaning and maintenance of the condensate drain line. Use PTFE tape to ensure a watertight connection when installing the adapter. Easy to Install: The SS2 float switch includes a 3/4-inch adapter, bus, cover, and switch. Install the included 3/4-inch adapter onto the auxiliary drain of the main pan and connect the 6-foot wire to the HVAC control board or thermostat wiring. Use PTFE tape to ensure a watertight connection when installing the adapter. Note: This float switch is designed for low-current applications (0–0.2 A) only and must not be used to directly power loads. When interfacing with high-power devices, use an external relay or solid-state relay (SSR) for signal isolation and output transition.
