Maintenance operations of the unit are required 3-4 times per year. They include regular cleaning of the unit and periodic cleaning of filters.
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.
Vacuum cleaning is allowed.
After two consecutive cleanings filters must be replaced.
For new filters, contact the Seller.
Filter cleaning periodicity for electrostatic filters is from 7 to 21 days, determined by the user based on the results of a visual check of the filter.
To replace/clean filters, follow these steps:
1. Unlatch the service panel.
2. Open the service panel.
3. Pull the filters to remove.
4. Clean the filters with a vacuum cleaner.
5. Assemble the unit in the reverse order.
2. 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 fans with a soft brush or cloth. Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.
3. 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.
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.
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS!
