BIG ASS FANS COLD FRONT 300 Mode D'emploi page 6

The cooler must be placed on level ground to operate correctly. Evaporative coolers create an oval-shaped
air pattern. Obstacles such as racks and workbenches may interfere with airflow. Position the cooler so that
interruption of the air pattern is minimized. Multiple coolers may be required to cover larger areas.
There are three major factors to consider when determining where to place the cooler.
1. Fresh Air Supply. The inlet side of the cooler (pad side) requires a constant, uninterrupted supply of fresh air
for maximum performance. A distance of 3 ft (0.9 m) of clear space to any obstructions at the rear or inlet side
of the cooler is recommended.
2. Discharge Airflow. The cool air discharged from the cooler should be free from obstruction to promote air
circulation in order to maximize the cooling zone.
3. Ventilation. Adequate ventilation is needed ensure the cooler does not recirculate air that has already been
through the evaporative cooling process.
Filling the cooler with water
Once the cooler has been connected to a water source, turn the water supply valve on and the cooler will fill
with water. The float valve will shut off the water flow when the sump is full.
Starting the fan
Set the fan switch to the ON position and adjust the speed to your preferred setting.
Starting the pump and adjusting the water flow
The cooling media in your new cooler will take a few hours to become fully saturated, and the media may
initially produce an odor. Flush the cooling pads for 5 hours with the flow control valve fully opened to ensure
the best efficiency of your cooler. During this time, the odor should also dissipate. For best results, change the
water in the reservoir frequently.
Once the cooling pads are fully flushed:
1. Fill reservoir with water.
2. Turn on fan.
3. Adjust water flow with flow control valve until water streams over pads.
Do not flood the pads with water. You should see several 1" to 2" (25 to 51 mm) wide dry streaks on the face of
the pads. If dry streaks grow wider, adjust flow to allow more water.
Prolonged use of hard water without proper water treatment will create mineral deposit buildup. This will
cause the pump to fail and is NOT COVERED BY WARRANTY.
Pump is equipped with a low water cutoff that may take up to five (5) minutes to reset each time.
