Evaporative Cooling
The principal of your unit is to introduce fresh air, which is washed through the filter pads to
provide cool fresh air. The air is exhausted taking with it any heat loading on the home.
Exhaust
It is essential for successful operation of evaporative air-conditioning that there are sufficient
exhaust openings in the area to be ventilated. Open doors and windows will usually provide
this.
The minimum exhaust opening should be 10 ft² for the 5,000 cfm unit and 14 ft² for the 7,000
cfm unit.
