• Pad replacement. The pads should be replaced after 5 years or before if necessary. To change pads, remove top access panel, remove grill, and disconnect water delivery tube. Remove water distributor holder and lift out media sections. Replace with the same type media. You can purchase them from your dealer.

IMPORTANT: In order to get the best performance from your cooling pads, they must be installed properly. If you have pur- chased a pad with two equal angles, the following instructions can be disregarded. Pads must always be installed with the steeper flute angle sloping down towards the air entering side (Fig. 6). The reason is simple. The

steeper angle puts more water on the hot, dry, dirty side of the pad where it is needed most. It also coun-

teracts the tendency of the air to push the water to-

ward the back of the pad.

•Cleaning pumps. Cleaning the

pumps is necessary once a year at start-up. For your safety, discon- nect from power source and unplug pump. Remove the pump from the mount bracket. Remove the base of the pump (Fig. 7). Clean the pump and turn the impeller to ensure free operation. Remove the

pump spout and check for any blockage. After cleaning, reinstall the base onto the pump. Reattach the pump to the mount in the cooler to ensure that the pump will not overturn. Do not forget to replace the spout and water delivery tube onto the pump outlet.

NOTE: The pump has automatic reset thermal protection. The pump motor will stop if it overheats. The pump will operate normal again after obstruction is cleared.

•Check bleed-off valve to be sure it is not clogged.

Winter Shut Down

•Drain water. Always drain all of the water out of the cooler and water supply line when not in use for prolonged periods, and par- ticularly at the end of the season. Keep the water line disconnected from both the unit and water supply so that water will not seep into the line and freeze.

•Disconnect from power supply when not in use for extended periods of time.

•Cover unit. To protect the life of the finish, a cover for the unit is suggested in extended periods of non use.

By following the operating, installation, and maintenance suggestions as outlined, you can get many years of efficient and satisfactory service from your cooler. In the event additional information is de- sired, your dealer will be more than glad to assist you in every possible way.

FAD242, FAD248 specifications

Essick Air's FAD248 and FAD242 evaporative coolers are engineered to enhance indoor comfort and air quality, making them popular choices for residential and commercial spaces. Both models utilize a natural and energy-efficient cooling process, providing a refreshing respite from heat during the warmer months.

The FAD248 model is noted for its significant cooling capacity, making it suitable for medium to large-sized rooms. It features a powerful motor that delivers a high air output, ensuring that even the hottest spaces can maintain a comfortable temperature. On the other hand, the FAD242 is designed for slightly smaller areas, providing ample cooling with a slightly lower output while maintaining energy efficiency.

Both models employ advanced evaporative cooling technology that operates by drawing warm air through water-saturated pads. As the air passes through these pads, moisture evaporates, consequently lowering the air temperature. This process not only cools the air but also adds beneficial humidity, which can alleviate dryness and improve respiratory comfort.

The construction of the FAD248 and FAD242 includes durable, high-quality materials designed to withstand the rigors of continuous use. The exterior housing is typically constructed from robust plastics that are resistant to wear and tear, ensuring longevity. Furthermore, both coolers are equipped with large water reservoirs, allowing for extended periods of operation without the need for constant refilling.

In terms of usability, the FAD248 and FAD242 incorporate user-friendly controls that allow for easy adjustments to fan speed, cooling settings, and oscillation options, providing users with the flexibility to customize their cooling experience. Many models include a remote control feature for added convenience, allowing users to operate the unit from a distance.

Energy efficiency is a key highlight of both the FAD248 and FAD242, designed with efficiency in mind to minimize electricity consumption. This means users can enjoy cooler indoor environments without incurring high energy costs, making these coolers an environmentally friendly choice.

In summary, the Essick Air FAD248 and FAD242 evaporative coolers are practical solutions for effective and energy-efficient cooling. With user-centered designs, durable construction, and advanced evaporative technologies, they contribute significantly to enhanced indoor air quality and comfort, catering to the needs of different room sizes while promoting an eco-friendly lifestyle.
