MAINTENANCE
CLEANING
CAUTION: Turn off the evaporative cooler and disconnect the plug from the electrical outlet
before cleaning, servicing or performing any maintenance on the unit.
CLEANING THE EXTERIOR SURFACE OF THE EVAPORATIVE COOLER
• Clean the plastic housing with a duster or a soft moist cloth.
• Do not use chemical solvents (such as benzene, alcohol or gasoline) as they may cause irreversible
damage.
• Use care when cleaning around the control panel and the control panel itself; make sure no water
enters the control panel. Control Panel warranty does not cover damage caused by water.
CLEANING THE RESERVOIR
• Unplug the appliance then remove the screws securing the rear filter frame.
• Lift the filter frames to remove from the unit.
• Drain the Reservoir by removing the Drain Plug on the underside of the Reservoir.
• With a cloth (dipped in mild detergent solution), wipe the Reservoir and rinse it with water.
• Cleaning the Reservoir at least once a week will help reduce any mineral deposits and keep the filters
clean.
• Do not run the unit in cooling mode with stale water in the Reservoir.
• Empty the reservoir and refill it with fresh water if water has been left in the Reservoir for an
extended period.
MAINTAINING AND CHANGING THE RIGID MEDIA PADS
The frequency of cleaning the Rigid Media Pads depends on local air and water conditions. In areas
where the mineral content of the water is high (hard water), mineral deposits may build up on the media
pads and restrict air flow. If mineral deposits remain on the media pads, they should be removed and
washed under fresh water or replaced. We recommend cleaning the media pads at least every two
months, depending on water conditions.
For best results, allow the media pads to dry after each use by turning off the cooling function for 15
minutes (without water in the Reservoir) before turning the unit off.

Media Pads.
