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.
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.
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.
