Notes:
(1) 346 volt units require 346/200 volt 4 wire system. (2) 415 volt units require 415/240 volt 4 wire system.
KW rating = humidity output (lb./hr.) x 0.345 (for energy calculations only; not for branch circuit sizing).
*Nominal Amp Rating is for breaker sizing and UL purposes only. Average operating amperage is 88% of normal rating.
Capacitieis listed in table are based on average amperage draw.
