Description
The Xylem-McDonnell & Miller FS4-15SS Paddle Kit is a flow-sensing component used with FS4-3 series flow switches in water circulation HVAC systems. This kit has stainless steel components with sizes matching A 1″ 2″ 3″ & 6″ 310451 in pipe diameter, and this enables the switch assembly to be configured to fit various pipe sizes installed. It is attached to the switch mechanism and extended into the water stream, where the flow of the fluid deflects it to cause the internal switch contacts to be closed.
