Preparation for Storage
Maintenance
Clean the air conditioner and filters regularly to maximize
performance and efficiency, and prolong the unit’s life. Be sure to
always unplug the air conditioner from the power outlet before
cleaning.
Use a soft dry cloth to wipe the body clean. If necessary, use
lukewarm water to dampen a cloth to clean the unit.
Use a soft bristle brush to clean between the vents.
Carefully use a vacuum cleaner to clean the condenser coils
Never use abrasive chemicals, volatile substances, gasoline,
detergents, chemically treated cloths, or other cleaning solvents
that may damage the cabinet exterior.
Never spray water directly on the unit.
To clean the pre-filter, follow the steps below:
1) Power off the unit and remove the pre-filter.
2) Remove the activated carbon filter.
3) Use a vacuum cleaner or tap the 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 in a cool and shaded place.
Dry thoroughly before reinstalling.
Clean the pre-filter periodically. If the unit is used in a dusty
environment you may need to clean it on a weekly basis.
Warning: Never operate the unit without the pre-filter.
If you are not going to be using the unit for an extended period of
time, follow the instructions below before storing your unit:
1) Drain all the water from the unit’s reservoir. Operate the unit in
fan mode for a few hours to thoroughly dry any moisture left on the
coils inside the unit.
2) Power off the unit, and clean or change the filters.
3) Unplug and carefully wind the power cord.
