Pre-filter and Evaporative Wick Maintenance It is necessary to clean the pre-filter and evaporative wick periodically. Depending on the environment, the pre-filter and evaporative wick may need to be cleaned on a weekly or biweekly basis. Note: If the pre-filter is exceptionally dirty, it will restrict the air flow the unit will be able to project. Follow the steps below to remove and clean the pre-filter and evaporative wick. Pre-filter 1. Slide the pre-filter straight up. Use a vacuum cleaner with a brush attachment or tap the pre-filter lightly to remove loose dust and dirt, then rinse thoroughly under lukewarm running water (below 104°F). You may use a mild soap and water solution if needed. Allow the pre-filter to air dry completely before reinstalling. Locking Tabs Evaporative Wick 2. After removing the pre-filter, remove the evaporative wick by pressing the locking tabs inward towards the center of the unit. Gently pull the wick out to remove it. Wash the evaporative wick with running water only. Depending on environmental conditions and amount of use, you may need to replace the evaporative wick after every season of use. Caution: Do not use pressure washers to clean the wick. KoldFront Evaporative Air Cooler 6
