LEGIOMIX Station sizing and selection procedure
3
A. Obtain the maximum GPM (demand) of domestic hot water from project documentation.
B. Select station size which has a Max GPM value equal to or greater than the project maximum GPM demand.
(1) The maximum GPM rating for the LEGIOMIX station is based on 5 feet per second pipe velocity in the station's
copper tubing. This velocity recommendation is for water temperatures up to 140°F and is from the UPC (Uniform
Plumbing Code) and the CDA (Copper Development Assocation) "Copper Tube Handbook". To minimize the
potential of erosion-corrosion in the station piping, do not exceed 5 fps velocity.
(2) The PSI/GPM table is for reference only, showing various GPM values at various pressure drops across the
station.
