TECHNICAL MAINTENANCE
Maintenance operations of the unit are required 3-4 times per year. They include general cleaning of the unit and the following
operations:
1. Filter maintenance.
Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning not less than 3-4 times per year.
To clean the filters, remove them from the unit. Dirty filters increase air resistance in the system and reduce supply air volume. The filters
require cleaning not less than 3-4 times per year.
2. Heat exchanger maintenance (once per year).
Dust deposits can accumulate on the heat exchanger. To maintain high heat recovery efficiency, regular cleaning is required. To clean
the heat exchanger, remove it from the unit and clean the heat exchanger by using compressed air or a vacuum cleaner. After cleaning,
reinstall the heat exchanger into the unit.
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 unit
capacity. 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).
Some dust may accumulate inside the air ducts which reduces the air quality and unit capacity.
Duct maintenance means regular cleaning or replacement.
