3. Fan maintenance (once per 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 cloth, brush, or using compressed air. Do not use water, aggressive solvents, or sharp objects as they
may damage the impeller.
4. 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.
5. Ductwork system maintenance (once in 5 years).
Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts,
which leads to air pollution and reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
6. Control unit maintenance (if necessary).
The control unit is positioned inside the unit casing. To access the control unit, remove the fixing screws on the panel and remove the
control unit lid.
