For faster cool down at initial startup fresh air damper (door) should be closed. After desired cooling tempera-
ture is reached, it is normally better to keep the fresh air damper (door) slightly open. During periods of very

When room or enclosure temperature reaches the desired level, slowly turn the TEMPerature control thermo-
stat knob toward INCREASE. Cooling will stop when you reach the approximate room temperature. Further
adjustment can be made by turning the TEMPerature control thermostat knob slightly toward DECREASE
