TECHNICAL MAINTENANCE
Maintenance operations of the unit are required 3-4 times per year. Maintenance includes periodic dust removal from surfaces, cleaning
or replacement of filters (when necessary) and dry cleaning of fans.
Maintenance includes general cleaning of the unit and the following operations:
1. Filter maintenance (3-4 times per year).
Dirty filters reduce supply air volume.
For cleaning, remove the decorative panel and the dirty filters from the unit
and clean them with a vacuum cleaner.
Install the filters back to the unit.
The filters require cleaning not less than 3-4 times per year.
For new filters, contact the Seller.
2. Heat exchanger maintenance (once a year).
Some dust may accumulate on the heat exchanger block even in case of
regular maintenance of the filters.
To maintain the high heat recovery efficiency, regular cleaning is required.
Periodical dry cleaning is recommended. Use a vacuum cleaner with a narrow
nozzle.
Remove the protective panels.
Remove the clogged heat exchanger out of the unit, clean it with a vacuum
cleaner and install the heat exchanger back to the unit.
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 fan with a cloth or a soft brush. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
4. 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.
