3.4Altitude

The standard units are designed for full load operation up to 4000 feet (1200m) above sea level. See Figure 1 for recommended deratings for altitudes greater than 4000 feet (1200m).

Altitude, Feet (M) Above Sea Level

Operation at full load at a higher altitude can be accommodated in ambient temperatures less than 104°F (40°C) ambient. Figure 2 shows the maximum allowable ambient temperature for full load operation at altitudes above 4000 feet (1200 m).
