  • Page 18 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. 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.
