Dehumidifier displays "CF" or "CL" indicating filter or cleaning reminder.

Safety: Unplug the dehumidifier before cleaning.

• Clean air filter: Remove the intake filter and wash it with lukewarm water and mild detergent. Rinse thoroughly and let it dry completely before reinstalling.
• Clean coils: Gently vacuum the evaporator and condenser fins with a soft brush attachment. Do not bend the fins.
• Reset indicator: Consult the Medisana manual; typically, pressing and holding the filter or timer button for several seconds will reset the "CF" indicator.
• Check airflow: Ensure there is adequate clearance around the unit for proper air circulation.
