BG-301 – FLOAT SWITCH (PRIMARY, ELBOW)

A float switch is a safety device that shuts your AC off if the condensate drain line clogs. Without one, a clogged drain can overflow and cause water damage to your ceiling, walls, or floors. The BG-301 installs inline on the primary drain line with a 90-degree elbow — use it when your drain exits the unit horizontally and turns down.

Specs: Primary drain line mount, 90-degree elbow fitting, normally closed, 24V compatible

Replaces: BG-301

Fits: Universal — works with any AC system that uses a 3/4″ PVC condensate drain line
