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

CAUTIONProlonged 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 pumpOn 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 startupsOn subsequent startups, turn on the pump, start the fan, and cool down.

Low water indicatorThe cooler is equipped with a low water indicator light.

  • When the power is on and there is sufficient 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 fanTurn the fan control knob clockwise to turn on the fan and adjust the speed to your preferred setting.

MAINTENANCE AND STORAGE

WARNINGELECTRICAL 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 mediaRemove 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 maintenanceAfter each use, turn off the pump about 15 minutes before the fan is turned off to allow the pads to drain and dry out. This controls mildew and bacteria growth for a long and efficient pad life. Drain the water from the cooler if it will be unused for a prolonged period of time.

Periodic maintenanceThe 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 efficiency, keep the cooling media and sump clear of debris. Water treatment tablets are available at bigassfans.com.

Draining the water sumpDepending 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 off 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 mediaEnsure the cooling pads are kept clean and dust-free. Dust and other particles have an adverse effect 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.

TROUBLESHOOTING AND REPAIR

MAINTENANCE

Spring cleaning

  • Remove the cooling media and clean out any debris in the water pan at the bottom of the cooler.
  • Remove the distribution tube from the mounting clips. Remove the plug at the end of the tube and flush out. Clean the distribution holes with a small brush and flush with water to verify all holes are clear.
  • If the cooling media is heavily stained with minerals or is damaged, replace the media. Replacement cooling media is available at bigassfans.com. Verify the media is  installed correctly with the arrows on the side.
  • Connect the water line and turn on the water supply. Check the float valve and make sure it is operating properly. Verify that the float valve is shutting the water off before walking away.
  • Switch on the fan motor and pump. Make sure the cooling media is being evenly saturated with water. Small dry streaks are acceptable.

Mid-summer checkup

  • Make sure the float valve is working properly. If the valve sticks, the water will run continuously and flood the reservoir. If this occurs, install a new float valve or contact Customer Service.
  • Check all other working parts for cracks or damage, including the pump, fan motor, and fan belt.
  • Check the condition of the cooling media. The cooler runs most efficiently when the media is clean. If the media has a heavy accumulation of mineral deposits, replace it.
  • Use the drain valve to empty the reservoir. Remove any debris.

Winterize

  • Clean the minerals from the reservoir. Vinegar can be used to dissolve buildup. Flush out the reservoir through the drain plug.
  • Inspect the water distribution tube for clogged holes. Clean as necessary.
  • To prevent freezing in the cooler’s waterline, disconnect the water supply, and then open both valves on the side of the cooler to dry out the reservoir.
  • Use a storage cover to protect your cooler and keep it clean.
