• WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death.
• CAUTION: Do not connect to a water source where water pressure exceeds 60 PSI (4 bar/414 kPa). This will cause permanent damage to the cooler.
• CAUTION: If using an extension cord, do not exceed the cord’s amperage ratings. Undersized extension cords create excessive drops in voltage, causing the electric motor to generate excess heat. This results in inefficient motor operation and premature motor failure and will void the warranty.
• CAUTION: Use caution when troubleshooting or repairing electrical components. Ensure power is disconnected from the cooler before the cooling media or fan guard is removed to gain access to the fan.
• CAUTION: Repairs should be performed by a qualified technician.
• CAUTION: If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly qualified persons in order to avoid a hazard.
• CAUTION: The Big Ass Fans product warranty will not cover equipment damage or failure that is caused by improper installation or use.
• 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.
• DANGER: Hazard to humans and domestic animals. Keep water treatment tablets out of reach of children. Causes severe eye and skin damage. Keep away from eyes, skin, and clothing. Harmful if swallowed.
• DANGER: Wear face shield or goggles and rubber gloves when handling water treatment tablets. In case of contact, flush with water and seek medical attention.
• WARNING: To avoid contamination, do not store water treatment tablets near drinking water, food, or feed. Do not reuse the empty container. Dispose of contents/container in accordance with local/regional/national/international regulations.
• CAUTION: Be aware that high humidity levels may encourage the growth of biological organisms in the environment. CAUTION: Never leave water in the reservoir when the appliance is not in use.
• The appliance is not to be used by children or persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction.
• Children being supervised should be instructed not to play with the appliance.
• Cleaning and user maintenance shall not be made by children without supervision.

OPERATION

1. Fill cooler
   Connect one end of a garden hose to the water supply and the other end to the cooler’s water supply inlet. Turn on the water supply. The water flow will automatically shut off when the cooler is full.

2. Plug in cooler
   Plug the power cord into a fused or breaker-protected circuit.

3. Turn on pump
   Make sure the cooler’s drain valve is fully closed. Turn on the pump on/off switch.

4. Adjust water flow
   Adjust the flow control valve until a visible flow of water trickles evenly down the cooling media. Make sure water is not splashing outside of the cooler.

5. Flush new cooling media
   Skip this step if you are not using new cooling media.
   When starting the cooler for the first time or after replacing the cooling media, run the pump for five hours without the fan running to flush the new media.

6. Turn on fan
   Turn on the fan control knob and adjust the speed to your preferred setting.

7. Shut down cooler
   Turn off the pump and leave the fan running for 30 minutes to dry out the cooling media, and then turn off the fan. Allow the cooling media to dry out completely once every 24 hours to prevent algae growth.

MAINTENANCE

WARNING: ELECTRICAL SHOCK HAZARD. Disconnect the power supply before performing service or maintenance. Failure to do so may result in serious injury or death.

Daily

• Allow the cooling media to dry out completely once every 24 hours to prevent algae growth.

Weekly

• Check the cooling media for bowing, sagging, or dry streaks.
• Remove the cooling media (see page 6) and inspect the water reservoir. Remove any debris and make sure the reservoir is clean.
• Check the water distribution system for leaks and check for clogged holes in the spray bar.

Bi-Weekly

• Clean the water reservoir every three days. See the following page for draining and cleaning instructions.

Monthly

• Add two water treatment tablets to the cooler’s reservoir to avoid scale and mineral buildup (Fig. 1). Tablets can be purchased at bigassfans.com. Tablets may need to be added more often if the water quality is poor.

Quarterly

• Drain and clean the water reservoir, water distribution system, and cooling media. See the following page for draining and cleaning instructions.
• Check all cooler components for cracks or damage, including the pump and fan motor.
• Make sure the cooler’s float valve automatically shuts off the water flow when the cooler is full.

Annually to every three years

• Replace the cooling media. Replacement cooling media can be purchased at bigassfans.com. The media may need to be replaced more often if it becomes heavily stained with minerals or is damaged. See pages 6–7 for instructions on removing and installing cooling media.

Storing/winterizing

• Drain and clean the water reservoir, water distribution system, and cooling media. See the following page for draining and cleaning instructions.
• To prevent freezing in the cooler’s water line, disconnect the water supply, and then open the flow control valve and the drain valve to dry out the reservoir.
• Store the cooler in a dry area and cover it to prevent damage and dust buildup. Storage covers can be purchased at bigassfans.com.

Draining and cleaning the cooler

1. Drain cooler

   • a. Option A: Close flow control valve. Connect a garden hose to the drain valve on the front of the cooler (optional, Fig. 1).

   • b. Option B: Remove the drain plug from the bottom of the cooler (Fig. 1). Allow water to drain, and then replace the drain plug. Do not tilt the cooler to remove or replace the drain plug.

2. Turn off and unplug the cooler.

3. Remove cooling media (see page 6) and clean with water and a soft brush. Do not use bleach, vinegar, or other harsh cleaners.

4. Clean out the water reservoir with a towel or wet/dry vacuum.

5. Remove the spray bar from the mounting clips and remove the plug at the end of the spray bar (Fig. 2). Make sure water distribution holes are free of debris. Reattach the plug to the spray bar and reinstall the spray bar into mounting clips.
   Make sure water distribution holes are facing upward.

6. Reinstall cooling media (see page 7).

7. Refi ll cooler with water (unless storing/winterizing).

Removing cooling media
