c Based on 50ºF chilled water supply temperature and 95ºF ambient air. Optional additional process pump hp reduces
chiller capacity by 0.2 tons per hp.
d Based on 2.4 gpm per ton, nominal 1 pump. Optional additional process pump hp reduces chiller capacity by 0.2 tons
per hp.
e Customer use of ductwork requires optional high-pressure fan for 5 hp to 15 hp models.
f An optional oversized process pump adds to the total rated or running chiller amperage. To find the new total chiller
amperage, subtract the standard process pump amperage from the optional pump amperage (see bottom of Page 4),
and add it to the chiller rated or running amperage.
g Multiply 460/3/60 amperage by 2.0 for 208-230/3/60 amperages; multiply by 0.8 for 575/3/60 amperages.
