Page 13: Technical Maintenance
TECHNICAL MAINTENANCE Maintenance operations of the unit are required 3-4 times per year. Maintenance includes 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. Clean the filters as required, but not less than 3-4 times per year. - Page 14 DVUT/DVUE HB(E/E2) EC V.2 2. Heat exchanger maintenance (once per year). Some dust may accumulate on the heat exchanger even in case of regular maintenance of the filters.
