This Ice Machine Installation Kit has been developed and put together by Marshall Webb Co. They were designed to facilitate and reduce labor by providing all needed components for proper installation. It is always recommended to have a licensed plumber do all installation work, not only for quality assurance but to prevent warranty issues later. If you're replacing a prior ice machine, it is important to install a new inlet and drain system and not to reuse the old one. This kit is only good for Scotsman and Manitowoc Commercial Ice Machines.
