Description

The Manitowoc RT50R404A is a 50-foot, factory-pre-charged refrigerant line set designed for seamless integration with Manitowoc R-404A remote ice machine systems. Engineered for the 500, 600, 850, and 1000 series, this kit facilitates the connection between an indoor ice head and a remote outdoor condenser. By moving the heat-exchange process outside, you significantly reduce kitchen noise and ambient heat, leading to lower HVAC costs and a more comfortable work environment. Each line is factory-dehydrated and pre-charged with a specific amount of R-404A refrigerant, featuring quick-connect fittings that allow for a professional installation without the immediate need for complex field charging or brazing.

Technician’s Note: The RT50R404A is pre-charged to simplify the setup of R-404A systems. When installing, it is vital to avoid kinks in the 50-foot run, as these can restrict flow and damage the compressor. When connecting the quick-connect fittings, use two wrenches to ensure a tight, straight fit; you must hear the “hiss” of the diaphragm piercing to confirm the refrigerant circuit is open. If your installation requires a vertical lift of more than 15 feet, ensure you have planned for proper oil return to the compressor to prevent premature failure.
