Maintenance operations of the unit are required 3-4 times per year.  This includes checking for visible damages and faults, regular cleaning 
and the following operations:

1. Filter maintenance (3-4 times per year).

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.  
Vacuum cleaning is allowed.  After two consecutive cleanings filters must be replaced.  For new filters contact the Seller of the unit.  The 
steps to replace the filters are as follows (refer to the figure on p. 21):
1. Press out on the latches.
2. Open the unit panel.
3. Remove the filters from the unit.

2. Fan maintenance (once a 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 brush or cloth.  Do not use water, aggressive solvents, or sharp objects as they may damage the impeller.

3. Heat exchanger maintenance (once a 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 pull it out, flush the heat exchanger with warm detergent 
solution. After cleaning install the dry heat exchanger back to the unit. To remove the filters and the heat exchanger follow the operations 
described in Fig. 19:
1. Release the latches and remove the bottom panel.
2. Open the unit panel.
3. Remove the heat exchanger.

4. Technical maintenance of condensate drainage system (four times a year).

The condensate drainage (drain line) may get clogged by dirt and dust particles contained in the exhaust air.  Check the drain line 
operation by filling the drain pan under the unit with water, clean the U-trap and the drain line, if necessary.

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. Technical maintenance of air duct system (every 5 years).

Even regular fulfilling of all the prescribed above maintenance operations may not completely prevent dirt accumulation in the air ducts 
which reduces the unit capacity.  Duct maintenance means regular cleaning or replacement.

TECHNICAL MAINTENANCE

DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE 

OPERATIONS!

ENSURE THAT THE UNIT IS SWITCHED OFF FROM THE SUPPLY MAINS BEFORE 

REMOVING THE GUARD.
