•Based on 50ºF (10ºC) chilled water supply temperature and 85ºF (29ºC) tower water. ‚ Based on 2.4 gpm per ton (9.1 lpm per 3.517 kW).

ƒ Based on availability of 85ºF (29ºC) tower water at 25 psi (172.4 kPa/1.7 bars) minimum.

„ Multiply 460/3/60 amperage by 2.0 for 208-230/3/60 amperages; multiply by 1.2 for 380/3/60 amperages; multiply by 0.8 for 575/3/60 amperages
