TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS.
FOLLOW THE SAFETY REGULATIONS WHEN CARRYING OUT 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.
Clogged 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 cleanings filters must be replaced. For new filters contact the Seller.
To clean or replace the filters, remove the detachable plates located on the service side of the unit. After cleaning install the filters and
the detachable plates in the reverse order.
2. Heat exchanger maintenance (once a 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. Before removing the heat exchanger,
unscrew the 7 screws and remove the cover. 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.
