OPERATION
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 (mesh sides) 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 to ensure the cooler does not
recirculate air that has already been through the evaporative cooling process.
Operating the cooler
1. Fill the reservoir
After connecting the cooler to a water source, turn the water source on to fill
the cooler with water. The float valve will shut o the water flow when the sump
is full.
2. Turn on the pump
When starting the cooler for the first time or after installing new cooling media,
turn on the pump and run the cooler without the fan running for 5 hours. On
initial startup, the cooling media will take a few hours to become fully saturated.
During this time, the media may produce an odor. This odor will dissipate over
time. For best results, change the water in the reservoir a few times.
3. Turn on the fan
Turn the fan control knob clockwise to turn on the fan and adjust the speed to
your preferred setting.
The pump automatically shuts o if the water level is too low. If the pump will not
start or stops running, refill the cooler with water.
