When locating your air-cooled portable chiller and designing its ductwork, note any potential high
temperature conditions when discharging into your building and any negative pressures with the building
when discharging air outside.
Notes: • Customer use of ductwork requires the high pressure fan option. • Allow 30” (77 cm) minimum
clearance around the chiller footprint to facilitate free passage of cooling air and service accessibility •
Size the ductwork for maximum capacity • Support ductwork from the building structure, not off of the
