¼” copper tubing when not secured to solid surface near cooler will cause water hammering, all the way down the copper tubing to where it is connected to solid supply line. Secure 1/4″ copper tubing with rubberize hose clamp.

On AeroCool coolers, secure ¼” tubing within 18″ where tubing is attached to side of wet section.

If motor sheave is not properly adjusted the motor will overheat and shut off until it cools down.

On all window and mobile models, operating the unit without front discharge grill in place will cause the motor to over heat and shut off until it cools down.

When water is first introduced to the cooler the glue that holds the media together may emit an odor that smells offensive. This smell will go away after the media has been soaked well and rinsed. Run the pump long enough to wet out the pads and then dump the water. Repeat the process. Finally you can add a cap full of Downy liquid fabric softener to the water before restarting your cooler. This should make the smell go away.

Drain, flush and clean the reservoir. Ensure the cooler has a bleed-off or Programmable Drain Pump installed. You may need to clean or replace pads. If you have new pads you should run your pump with out the blower for a period of time to wash out some of the smell, during which time you also dump the sump of the water that has washed the pads.

If the water is not coming from the bleed-off or Power Cleaning Systems™ systematic flushing you may need to adjust the float or replace it. Refer to the Owner’s Manual for float adjustment instructions.

You may have inadequate exhaust. Open more windows or doors. For every 1,000 CFM of air delivery 2 sq. ft. of unrestricted air relief is required.

Check the water distribution system to make sure there is sufficient water to the pads and check pads to ensure they are not clogged. If pads are not wet, check to see if recirculating pump is operating. Follow the procedures in owner’s manual for servicing the pump. Remove the pump from cooler and plug it into another electrical outlet. If it still not working replace pump. Remember to periodically check the pads, clean them and/or replace as needed.

For all of the Aerocool products, the model and serial number can be found under the electrical connection, all others can be found on the rear top flange or the rear leg of the cabinet.

With the model and serial number handy, contact the contractor who installed your unit. If your unit was self-installed or is a portable model please contact our warranty department at 1-800-325-6952.
