TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS!
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.
When 3 000 operating hours have elapsed, the unit controller generates the filter replacement or cleaning alert. Clean or replace the
filters and reset the hour meter.
Vacuum cleaning is allowed. After two consecutive cleanings filters must be replaced.
For new filters contact the Seller.
Sequence of filter removal:
1. Disconnect the unit from power mains.
2. Remove the filter covers.
3. Remove the filters.
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 of the heat exchanger 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. Sequence of heat
exchanger removal:
1. Disconnect the unit from power mains.
2. Remove the filter covers.
3. Remove the side cover.
4. Disconnect the rotary heat exchanger and then unlatch and pull it to remove.
