c
Based on 50ºF (10ºC) chilled water supply temperature and 95ºF (35ºC) ambient air.
d
Based on 2.4 gpm per ton (9.1 lpm per 3.517 kW). 2.9 gpm/ton (11 lpm per 3.517 kW) for glycol/water mixes.
e
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
