Your dehumidifier is designed to serve you year-round.
Listed below are the care and maintenance instructions
leaning the Front Panel and Cabinet
• Using a soft cloth, clean the front panel and cabinet with warm water and a mild soap or
detergent. NOTE: Never sprinkle water into the appliance in order to prevent risk of shortcircuit and fire.
• Never use gasoline, thinner or any other similar chemicals for cleaning.
• Do not use bleach or abrasives.
leaning the Air Filter
If the filter is dirty, air circulation is compromised and the efficiency of the dehumidifying
decreases. It is therefore good practice to clean the filter at regular intervals. The frequency
depends on the duration and conditions of operation.
• To remove the air filter, pull it out (Fig. 6).
• Use a vacuum cleaner to remove dust accumulations from
the filter. If the filter is very dirty, wash in warm water and
rinse several times.
• After washing the filter, allow it to dry completely before
replacing it.
