The IceCap ATO EZ System includes a pump and sensor combo that offers peace of mind with its fail-safe design. The twin optical sensors minimize the frequent powering on and off of the refill pump, extending its life and reliability. Additionally, a third safety sensor provides an extra level of protection against overflows.

Installation is a breeze – simply move the magnet optical sensor to the desired water level in the return section of your sump and install the pump in your favorite ATO reservoir with the supplied tubing and accessories.

When the water level drops below the bottom low-level sensor, it blinks blue until the water level rises to the middle normal level sensor, at which point a solid blue light displays. The top safety level sensor acts as a backup, shutting down the feed pump and flashing a red light in case of a malfunction.
