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. Upon elapsing of 3000 operating hours the controller reminds about the need to replace or clean the filters. In this case clean
or replace the filters and reset the filter timer. Filter cleaning with a vacuum cleaner is allowed. After two consecutive cleanings the filters
must be replaced. For new filters of the type stated in the technical data, please contact to the unit Seller.

3. Turn the latches to release the filters.
