Maintenance operations of the unit are required 3-4 times per year. Maintenance includes regular
cleaning and the following operations:
1.
Filter maintenance
Dirty filters increase air resistance in the system and reduce supply air volume. The filters require
cleaning once in 3-4 months. Clean the filters with a vacuum cleaner or replace with a new filter. Contact
your local manufacturer representative for new filters.
2.
Heat exchanger inspection (once per year).
Some dust can get accumulated on the heat exchanger block even in case of regular maintenance
of the filters. To maintain the high heat exchange efficiency, regular cleaning is required. To clean the
heat exchanger pull it out of the unit and clean it with warm soap or mild detergent water solution. Re-
install the dry heat exchanger to the unit.
3.
Fan inspection (once per year).
Even in case of regular maintenance of the filters, some dust and grease can get accumulated inside
the fans and reduce the fan performance and supply air flow.
Clean the fans with a soft brush or cloth. No water and abrasive detergent, sharp objects or solvents
are allowed for cleaning to prevent the impeller damage.
4.
Condensate drainage (once per year).
The drain pipes may get clogged with extracted particles. Pour some water inside the drain pan and
check the pipe for clogging. Clean the U-trap and drain pipe if required.
5.
Supply air flow control (twice per year).
Leaves and other pollutions can clog the supply air grille and reduce the unit performance and
supply air volume. Check the supply grille twice per year and clean it as required.
6.
Ductwork system inspection (once in 5 years).
Even if you follow all the listed maintenance guidelines, some dust can get accumulated inside the
air ducts and reduce the unit performance. Duct maintenance means regular cleaning or replacements.
7.
Exhaust grilles and intake diffusers cleaning (as required).
Remove the diffusers and the grilles and wash them with warm water and mild detergent solution.
Do not change locations of the diffusers and the grilles.
