3. Fan maintenance (once a year).
Even in case of regular maintenance of the filters, some dust may accumulate inside the fans and reduce the fan performance and supply
air flow.
Clean the fans with a soft brush or cloth.
Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
4. Technical maintenance of condensate drainage system (four times a year).
Check the drain line operation by filling the drain pan under the unit with water, clean the U-trap and the drain line, if necessary.
5. Supply air flow control (twice per year).
The supply duct grille may get clogged with leaves and other objects reducing the unit performance and supply air delivery.
Check the supply grille twice per year and clean it as required.
6. Technical maintenance of air duct system (every 5 years).
Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air ducts
which reduces the unit capacity.
Duct maintenance means regular cleaning or replacement.
