CHECKLIST
DO
✓Read the Operation and Maintenance Manual.
✓Check all hose connections.
✓Use a 12 gauge cord if the cord is under 50 ft (15 m) or a 10 gauge
cord if the cord is over 50 ft (15 m).
✓Provide fresh air intake for the cooler and maintain a minimum
clearance of 3 ft (0.9m) behind the cooler.
✓Flush new cooling media.
1. Fill the cooler with water.
2. Switch on the pump.
3. Run the cooler without the fan running for at least 5 hours.
✓Make sure the cooling media is being evenly saturated by using the
control valve to adjust the water flow.
✓Drain and clean the cooler weekly. Remove the cooling media and
wash with a garden hose.
✓Use Refresh™ tablets (algae killer) and/or CTT-EC™ cooler treatment
tablets (mineral treatment). One algae killer tablet is provided in the
cooler's reservoir. Additional water treatment tablets are available
at bigassfans.com.
DO NOT
ΧDO NOT forget to dry out the cooling media before shutting down
the cooler. Turn o the pump and leave the fan running for 10 to 15
minutes.
ΧDO NOT run the pump without filling the reservoir with water first.
ΧDO NOT completely open the water valve. This may flood the
cooling media.
ΧDO NOT use a water source with more than 120 PSI of water
pressure.
ΧDO NOT operate the cooler in a sealed room. Allow for fresh air
intake and exhaust.

ASSEMBLY
IMPORTANT
Carefully examine the carton for damage before opening. If the carton is
damaged, notify the shipping company immediately.
Install casters
1. Locate the package of four (4) casters and remove from box.
2. Lay box on its side and carefully open bottom of box. DO NOT STAND BOX
UPSIDE DOWN.
3. Install the four casters.
4. Stand cooler up on casters and remove box.
SETUP
The cooler has been factory tested and is ready to use. Place the cooler on level
ground with the casters locked to prevent inadvertent movement.
Connecting the water supply
The cooler comes equipped with a female garden hose water source connection.
Use a standard garden hose (not provided) to connect the water supply to the
cooler.
CAUTION
Do not connect to any water source where water pressure exceeds 120 PSI.
This will cause permanent damage to the cooler.
Connecting the electrical supply
IMPORTANT
The cooler should be plugged into a fused or breaker-protected circuit. Refer
to Table 1 for circuit size requirements.

CAUTION
Do not exceed the amperage ratings of the extension cord. Undersized
extension cords create excessive drops in voltage, causing the electric motor
to generate excess heat. This results in inecient motor operation and
premature motor failure and will void the warranty.

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.
Filling the cooler with water
Once the cooler has been connected to a water source, turn the water supply
valve on to fill the cooler with water. The float valve will shut o the water flow
when the sump is full.

CAUTION
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.
Starting the pump
On initial startup, the cooling media in your new cooler 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.
Subsequent startups
On subsequent startups, turn on the pump, start the fan, and cool down.
Low water indicator
The cooler is equipped with a low water indicator light.
♦When the power is on and there is sucient water in the reservoir, the light will
be green and the pump will be running.
♦When the power is on and the water in the reservoir is low, the light will be red
and the pump will stop running.
Starting the fan
Turn the fan control knob clockwise to turn on the fan and adjust the speed to
your preferred setting.

MAINTENANCE AND STORAGE
WARNING
ELECTRICAL SHOCK HAZARD
Disconnect the power supply before performing any service or maintenance.
Failure to do so may result in serious injury or death.
Removing the cooling media
Remove the cooling pads to access the inside of the cooler.
1. Remove pad grilles from support channel.
2. Tilt pads from the top and lift out of the cooler.
Daily maintenance
After each use, turn o the pump about 15 minutes before the fan is turned o to
allow the pads to drain and dry out. This controls mildew and bacteria growth for a
long and ecient pad life. Drain the water from the cooler if it will be unused for a
prolonged period of time.
Periodic maintenance
The cooling pads act as a filter to remove dust and other particles from the
incoming air stream. The collected particles and any water impurities will flow into
the sump and collect there. To keep the cooler operating at peak eciency, keep
the cooling media and sump clear of debris. Water treatment tablets are available
at bigassfans.com.
Draining the water sump
Depending on how often you operate the cooler, drain the sump anywhere from
every week for heavy use to monthly for light use.
1. Turn cooler o and disconnect the power supply.
2. Remove drain plug located at bottom of reservoir and let cooler drain.
3. Remove cooling pads.
4. Clean out reservoir with either a towel or wet/dry vacuum.
5. Reinstall pads and grille.
Cleaning the cooling media
Ensure the cooling pads are kept clean and dust-free. Dust and other particles
have an adverse eect on the pads’ ability to introduce water into the air stream. If
the pad surface is dirty, clean with a soft brush and water. Never use bleach.
Storage
1. Remove cooling pads and clean with a soft brush and water to remove dust
and debris.
2. Drain sump and wipe dry.
3. Store cooler in a dry area and cover to prevent dust buildup.
