Cool – Push on, applies power to the Pump which provides water to the Spray Bar over the Media

Important The Fan start may be delayed up to a minute after pressing the Cool button. This
time delay allows the water to propagate through the Cooling Media prior to pulling
air through the Media.
Blast – Pushing the Cool button twice turns off the water pump and leaves the only Fan operating.
Timer – Push to scroll through preprogramed shutdown times. Allows the operator to select an
automatic shutdown time in 1 hour increments. Up to 24 Hours maximum.

sharp (e.g. screwdrivers, pens or a knife). Sharp objects can puncture the
membrane and damage the circuitry below requiring repairs not covered under
