3. Fan maintenance (once per year).
The regular filter cleaning may not completely prevent the dust ingress into the unit, which results in the unit capacity decrease.
Clean the fan with a soft cloth or a brush. Cleaning with water, abrasive detergents, sharp object or chemicals is not allowed.
4. Condensate drain system maintenance (once per year).
Extract air particles may accumulate in the condensate drain system and cause its clogging. Pour a drain pan under the unit with water to check free water
flow. Clean a U-trap and the drain system if required.
5. Supply air flow control (twice per year).
Check the supply grille and remove foreign objects to maintain free air intake.
