This kit converts an older box-type float valve on a PolarCool evaporative cooler to the current float valve design, giving you automatic water level control without manual refilling.
The 6450-7613 kit replaces the failure-prone box float mechanism found on older PolarCool units with the current-generation float valve. It's built for facilities that run coolers for extended shifts or around the clock, where manual water monitoring isn't practical. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
