3. Fan inspection (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 filters with a vacuum cleaner, a soft cloth or brush. Do not use water, aggressive solvents or sharp objects as they may damage the
impeller.
Access to the fans is from the side of air ducts connections.
4. Condensate drainage inspection (once per year).
The condensate drainage (drain line) may get clogged by dirt and dust particles contained in the exhaust air. 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. Exhaust louvre shutters and intake diffusers cleaning (as required).
Wash the diffusers and the louvre shutters with warm detergent solution.
6. 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.
7. Ductwork system inspection (once in 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.
