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:
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
chiller
• Back draft damper to outside must be closed at all times when fan/blower is not operating •
