1.2. Machine Nomenclature
E-Series water purification machines are numbered in such a way as to indicate the
permeate flow you can expect from the machine and other specifications.
Example: RO,E4-4400-DLX,460,6,HR(PA)
 RO indicates the machine is a reverse osmosis machine.
 E4 indicates the machine series (E) and 4-inch housings/membrane elements
 4400 indicates the rated permeate flow in thousands of gallons per day at 77F
(25C), i.e. 4400 = 4400 gallons per day
 DLX indicates the deluxe model and ECN indicates the economy model
 460 indicates 460 VAC, 3-phase voltage to starter. Standard models offer 460
VAC, 60 Hz, 3-phase and 380 VAC, 50 Hz, 3-phase.
 6 indicates 60 Hz operation, (50 Hz operation is also available and is indicated by
a 5 in place of the 6.
