Ambient air temperature is too high for optimal performance.

Air used for cooling the unit is above the temperature at which the unit is designed to run at maximum performance. The following checks will help determine the problem:

• If the room temperature is above the specified range for the unit reporting this problem, then take steps to lower the room temperature.
• If the air being drawn into the unit is above the specified range, either move the unit to a place where the air is within range, or take steps to reduce the temperature of the air surrounding the unit. This can be accomplished by moving the source of the air that is too warm.
• If the temperature of the air at the unit's air intake is within the range specified contact your next level of support.
