TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE 

OPERATIONS.

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.

Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning not less than 3-4 times per 

year. When 3 000 operating hours have elapsed, the unit controller generates the filter replacement or cleaning alert. Clean or replace 
the filters and reset the hour meter. Vacuum cleaning is allowed.  After two consecutive cleanings filters must be replaced.  For new filters 
contact the Seller.

Sequence of filter removal:
1. Disconnect the unit from power mains.
2. Remove the service panel.
3. Pull the filters to remove.

2. Heat exchanger maintenance (once per 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.

Sequence of heat exchanger removal:
1. Disconnect the unit from power mains.
2. Unlatch and open the service panel.
3. Disconnect the rotary heat exchanger and then pull it to remove.

3. Fan maintenance (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. 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.

5. Ductwork system maintenance (once in 5 years).

Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts, 

which leads to air pollution and reduces the unit capacity. Duct maintenance means regular cleaning or replacement.
