Loosen but do not remove the two panel latches.
Locate the economizer control module, where the fol-
lowing adjustments will be made.

Check that the damper blades move smoothly without
binding; carefully turn the Minimum Position Adjusting

clockwise and then set the thermostat indoor fan switch
to the on position and then off, or energize and de-
energize terminals "R" to "G".
