8.14 Altitude
Most equipment has been normally tested on a short-term basis for performance, up to an altitude of 2.4 kilometers
(8000 feet). Above this altitude, the operation of equipment may be impaired.
8.15 Airflow Rate Range
266-314 m3/h-kilowatts or 550-650 cfm/ton at the air-conditioner output
8.16 Vibration
Most equipment has been normally tested on a short-term basis for performance up to the vibration limits specified
below. Above these limits or with a continuous vibration level, the operation of equipment may be impaired
