Frequently Asked Questions

All our coolers come equipped with a bleed off tee and tube. The purpose of a bleed-off is to continuously eliminate a small quantity of water from recirculation, allowing fresh water to enter the reservoir to reduce scale build-up and dilute mineral concentrations. To determine the flow rate that is right for your cooler, refer to the Owner’s Manual that is appropriate for your model.

A bleed-off system is included in window and whole house coolers and should be installed as instructed in the Owner’s Manual. An optional alternative to the bleed-off system would be the installation of a Power Cleaning System, which is a standard feature of the Aerocool Pro-Series units.

The PCS115 Power Cleaning System will automatically replace the water in your cooler with fresh, clean water every 12 hours of pump operation. This will flush out the old, mineral-laden water in the pan and bring in all new clean water.

The Power Cleaning System keeps the evaporative cooler cleaner, uses less water than traditional bleed-off methods. The result is cleaner, more efficient pads, less scale build-up, and fresh, cool clean air.

Yes, the universal design works in any cooler. The Power cleaning system comes ready to install in just minutes and never needs adjusting. It is installed along WITH your existing primary re-circulating cooler pump.

Use and misuse of the above will result in voiding the warranty of the cooler.

Regular maintenance is essential and we recommend at a minimum of three times during the season for cooling comfort, extending the life of the cooler and to avoid unnecessary parts replacement. This service should be at start-up, mid-season and shutdown. Refer to the Owner’s Manual for a complete maintenance schedule.

No, it is recommended that soft water equipment not be attached to any water lines going to the cooler. “Soft Water” may cause corrosion and decrease the effective life of the cooler.

Use rust protective spray paint on the unit, especially on scratched surfaces.

Locate the oil port on the bearing assembly and add a few drops of 20W or 30W non-detergent oil. Do not use Zoom oil which is 10W turbine oil.

Check the set screws on the blower assembly hub, If loose, follow this procedure. If the setscrew is loose on the opposite of the pulley side, untighten the set screw so that is not touching the shaft, then grab blower wheel assembly and pull the assembly against the leather washer and bearing, with palm of your hand shove the blower shaft inward ( leaving no gap ) then tighten set screw. For additional information see below:CENTERING BLOWER WHEEL IN COOLER ON THE PULLEY SIDELocate end of shaft 1-7/8” from Bearing Assembly.
Pull Blower Assembly Hub against Bearing Assembly and tighten the Blower Set Screw.
Assemble Pulley onto Shaft and locate so it’s flush with edge of shaft.
Tighten Pulley Set Screw onto Shaft.

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 System™s 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.

SEER (Seasonal Energy Efficiency Rating) is a measure used for air conditioners. It refers to the BTU/hr of cooling, per watt of electricity. Evaporative coolers are rated by CFM, (Cubic feet per minute), of air flow. Since blower motors consume electricity based upon the horsepower of the motor, there is no energy rating that is the same as the compressor units.

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.
