3.4 Altitude

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).
Figure 1 Recommended derating for high altitude operation
Operation at full load at a higher altitude can be accommodated in ambient temperatures less than
104°F (40°C) ambient. Figure2 shows the m aximum allowable ambient temperature for full load
operation at altitudes above 4000 feet (1200 m).
