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 (3-4 times per year).
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. Sequence of filter
removal:
1. Unlatch the service panel.
2. Open the service panel carefully, supporting it with the hand.
3. Remove the filters from the unit.
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 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. In case of severe contamination, the heat exchanger can be washed with water.
After cleaning, reinstall the heat exchanger into the unit.
Sequence of heat exchanger removal:
1. Unlatch the service panel.
2. Open the panels supporting those with the hand.
3. Remove the drain pan after unscrewing 4 screws.
4. Unscrew 9 self-tapping screws holding the heat exchanger and remove it from the unit. Be careful when removing the heat exchanger.
