level mark. Running the unit with inadequate water may cause pump failure. If ice is available you may add ice in the top compartment to enhance the cooling performance. 1.7 CLEANING & MAINTENANCE Warning: Before cleaning the unit, switch it to the ''off'' position and remove the plug from the power socket. To clean the outside, use a damp cloth to remove dirt and dust. Never use corrosive elements or any chemicals to clean this product. When the product is not in use, store the unit in a dry place out of direct sunlight. Draining and Cleaning the Water Tank: Turn the power off and disconnect the air cooler from the power supply. Move the unit to a location where it can be drained. Remove the rubber plug from the tank and allow the tank to empty. Once the tank is empty, unlock the latches on both sides and lift off the cooler top section as shown in the figure and place it vertically on the floor. Refill the water tank with clean water and drain it completely. Clean the water tank with detergent or a damp cloth and rinse it thoroughly. Place the unit top carefully on the tank and lock the latches. Refill the water tank with clean water, up to the maximum level. The air cooler is now ready to be used. This cleaning process should be repeated weekly to maintain the integrity of the unit and to remove particles filtered from the air. Cleaning the Filter and Honeycomb: The appliance is supplied with carbon filter & honeycomb cooling media. Always keep the Carbon filter clean. You can wash the Carbon filter at least twice a year or whenever you feel necessary. The carbon filter and honeycomb media are located inside the back panel. Open the back panel by using a star screw driver to clean or replace the carbon filter or honeycomb media. It is recommended that the carbon filter and honeycomb media be replaced every year, depending on use and environment. Draining the water reservoir and refilling with fresh water at least once a week will greatly reduce mineral deposits in the pads and help to extend the life of Honeycomb cooling media. Do not run the unit in COOL mode with stale water in the tank. You must empty the water tank and refill with fresh water, especially if the tank has not been cleaned in a long time. The cleaning frequency for the Honeycomb media depends on local air and water conditions. In areas where the mineral content of water is high, mineral deposits may build up on the honeycomb cooling media and restrict air flow. Draining the water reservoir and refilling with fresh water at least once a week will help reduce mineral deposits. If mineral deposits remain on the Honeycomb media, the media should be removed and washed under fresh water. The media should be cleaned every two months or sooner, depending on your needs. For best results allow the honeycomb cooling media to dry after each use by turning off the cool function 15 minutes before turning the unit off. 9
