Avoid too much outdoor air coming into air-conditioned spaces.
Note that outlet air is cooler or heater than set room temperature. Avoid
direct exposure to outlet air as it may be too cool or hot.
Maintain a proper air distribution. Air outlet louvers should be used to adjust
the direction of outlet airflow, as doing so might ensure more efficient
operation.
