PLACEMENT CONSIDERATIONS
Clearance Requirements
Follow the ventilation (suction and discharge air flow) and service requirements as shown below and on the next page when choosing a
chiller installation area. The system used in the diagrams is a single frame system. The clearances detailed are the same for all frame sizes.
Ventilation Clearance Requirements
Air-cooled chillers must be installed in an open space or must have appropriate ventilation. If the chiller must be installed near one wall or under a
ceiling, there must be enough space for ventilation.
Installing Near One Wall
• If one side of the chiller is near a wall, and the height of the wall is
less than 32 inches, the clearance space between the chiller and
the wall must be a minimum of 32 inches.
• If one side of the chiller is near a wall, and the height of the wall
is greater than 32 inches, the clearance space between the chiller
and the wall must be a minimum of 32 inches plus half of h1 (differ-
ence between 32 inches and the total wall height).

Installing Under a Ceiling
• If the chiller is installed under a ceiling, the clearance space
between the top of the chiller and the ceiling must be a minimum of
197 inches.
• If the front or back of the chiller is near a wall, the clearance space
between the chiller and the wall must be a minimum of 32 inches.
