Air volume, air quality, and temperatureThe installation site must meet certain recommended requirements for air volume,temperature, altitude, and humidity ranges, and air quality.Air volume specificationsThe following table provides the recommended maximum amount of air volume.Table 8 Maximum air volume, VMAX 250FBay UnitsSystem bay, 1 V-Brick 490 cfm (13.9 m3/min)System bay, 2 V-Bricks 980 cfm (27.8 m3/min)Table 9 Maximum air volume, VMAX 450F, VMAX 850F, VMAX 950FBay UnitsSystem bay 1,325 cfm (37.4 m3/min)Temperature, altitude, and humidity rangesThe following table provides the recommended environmental operating ranges.Table 10 Environmental operating rangesCondition SystemOperating temperature and operatingaltitude a l 50° – 90° F (10° to 32° C) at 7,500 ft(2,286 m)l 50° – 95° F (10° to 35° C) at 3,317 ft(950 m)Operating altitude (maximum) 10,000 ft (3,048 m) 1.1° derating per 1,000ft bOperating relative humidity extremes 20% to 80% noncondensingOperating rate of temperature change 9° F/Hr (5° C/Hr)Thermal excursion 122° F (48° C) (up to 24 hours)a. These values apply to the inlet temperature of any component within the bay.b. Derating equals an operating temperature of 29.25° CTemperature and humidity range recommendationsThe following table provides the recommended operating and humidity ranges toensure long-term reliability, especially in environments where air quality is a concern.Specifications28 Site Planning Guide VMAX 250F, VMAX 450F, VMAX 850F, VMAX 950F with HYPERMAX OS
