Technical Maintenance - Vents MICRA 80 A3 User Manual

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 (3-4 times per year).
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.
Sequence of filter removal:
1. Lift the service panel latches.
2. Open or remove the service panel. Remove the panel with care.
3. Remove the filters from the unit.
2. Heat exchanger inspection (once per year).
Some dust may accumulate on the heat exchanger block 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.
Sequence of heat exchanger removal:
1. Lift the service panel latches.
2. Open or remove the panel carefully, supporting it with the hand. Remove the panel with care.
3. Remove the heat exchanger.
3. Fan inspection (once per year).
Even in case of regular maintenance of the filters, some dust may
accumulate inside the fans and reduce the fan performance and supply
air flow.
Clean the fans with a soft cloth or brush.Do not use water, aggressive
solvents or sharp objects as they may damage the impeller.
4. Exhaust louver shutters and intake diffusers cleaning.
Wash the diffusers and the louver shutters with warm detergent
solution. Exhaust louver shutters and intake diffusers cleaning (as
required).
5. Supply air flow control (twice per year).
The supply duct grille may get clogged with leaves and other objects
reducing the unit performance and supply air delivery.Check the supply
grille twice per year and clean it as required.
6. Ductwork system inspection (once in 5 years).
Even regular fulfilling of all the maintenance operations described
above may not completely prevent dirt accumulation in the air ducts
which reduces the unit capacity. Duct maintenance means regular
cleaning or replacement.
