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. Clean the filter with a vacuum cleaner or replace it with a new
one. For new filters contact the Seller.
To extract filters, do the following:
1. Disconnect the unit from power mains.
2. Remove the decorative panel.
3. Remove the service hatch.
3. Pull the filters to remove.
2. Heat exchanger maintenance (once per year).
Some dust may accumulate on the heat exchanger even in case
of regular maintenance of the filters. To maintain the 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, re-
install the heat exchanger into the unit.
To remove the heat exchanger, do the following:
1. Disconnect the unit from power mains.
2. Remove the decorative and the service panel.
3. Disconnect the ground cable from the service panel.
4. Disconnect the heat exchanger and then pull it to remove.
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. Fans should be cleaned selected by the service technician.
4. Supply air ow 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. 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.
