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 …
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.
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 …
Yes, all of the residential cooler motors that we use are thermally protected.
The Trophy Series is the base model of the Pro Series. The Pro Series units come with all the extra goodies such as Power Cleaning System, Pro-Stat (Thermostat) and Winterizing Panel and the motor comes factory installed and pre-wired.
Yes. PMI™’s Aerocool Pro Series Cooler is equipped with its own specific thermostat designed specially for that model. Additionally, PMI now offers The Nth Degree (NDS) which is UL-listed, easy to install and works with any cooler that is 115V or 230V and has up to 1 horsepower motors.
The CFM rating for the units can be found on the brochures for each unit. Please refer to support center and click on “Downloads” to select the brochure for your product.
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 …
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.
Please visit the warranty section on this website for your specific model.
Use rust protective spray paint on the unit, especially on scratched surfaces.
Drain, flush and clean the reservoir. Ensure the cooler has a bleed-off or Power Cleaning System 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 …
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.
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.
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.
Use and misuse of the above will result in voiding the warranty of the cooler.
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.
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.
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.
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.
Up-dux is a ceiling vent which allows the air to pass through the attic area and out through the roof vents. When the cooler comes on, the air pressure automatically opens the up-dux barometric dampers and when the cooler shuts off, the damper automatically closes.
Nature’s most efficient means of cooling is through the evaporation of water. Evaporative cooling works on the principle of heat absorption by moisture evaporation. The evaporative cooler draws exterior air into special pads soaked with water, where the air is cooled by evaporation, then circulated into your space.
All PMI 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 …
Other than the direction of the vents, you can control the flow of air by opening the windows or doors of different rooms that you want to pull the air into.
Evaporative cooling has gained rapid acceptance because the process relies solely on water evaporation with extremely low energy consumption to produce a significant amount of cooling. Evaporative cooling will generally pay for itself (including installation) in just a few seasons. This equates to a great investment for consumers who on the average own the same home for 5-6 years. Also …
Yes. You may install up-dux vents to exhaust the air through your attic and out the roof vents. By exhausting cool air through the attic, you can reduce the temperature of this hot spot and make your home more comfortable. It is important to remember to provide adequate exhaust in the attic area. Provide 2 sq. ft. of relief for every …
You should open your windows until the air pressure inside the house is nearly balanced with the air outside. One method used to determine when air is reasonably balanced is to place a tissue paper against the screen in the window furthest from the cooler and adjust the opening of the other windows in the house until the tissue paper …
The evaporative cooler draws fresh exterior air through special pads soaked with water. The air is cooled, filtered and circulated through the home. The hot, stale air needs to exit and this is referred to as “relief air”. The best “relief” design is to exhaust slightly less air then your cooler is supplying. This will ensure that your home has a slight positive …
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. …
Aspen pads are made of shredded aspen wood and are approximately 75% efficient. Rigid Media pads are made of glued together cellulous material that is honeycomb in shape and the standard product is approximately 85% efficient.
Please visit our Sizing chart for more information.
Many different choices are available; window units, portable units, ducted roof mount units, all the way to large industrial units. There are also many types of media for each of the above cooler styles.
An evaporative cooler consumes about one-quarter of the electrical energy required to operate a refrigerated air conditioning unit. You can save up to 80% on your summer cooling bill!
