*  In serial, the units are supplied with F7 as standard and M5 as extraction. All models allow the assembly of a second filter inside, obtaining, among others, 

the following combinations: F7 + F9, M5 + F7 or G4 + F7.

7.2. ADDITIONAL FILTER INSTALLATION

The heat recovery is supplied with mounted filters.

Low pressure F7 filter for supply air and M5 for extract air.

Inside the heat recovery unit there is a specific rail for mounting a second additional filter (supplied as an accessory).

7.3. HEAT EXCHANGER

To perform the heat exchanger cleaning it is necessary to remove it from the unit. The disassembly can be easily done 

from the lateral panel:
Core disassembly sequence per side
To disassemble of the heat exchanger follow the following sequence:
• Loosen the screws that hold the side panel. Before releasing the panel, ensure that it is well supported by the opera-

tor, preventing it from falling (Fig. 1).

• Remove the bypass assembly, releasing its electrical connector (Fig. 2).

• Pull the heat exchanger until it is completely removed from the equipment (Fig. 3).

7.4. FANS

It is not necessary to access the fan to carry out maintenance tasks, nor to carry out the electrical connection since both 

fans are wired to the electrical cabinet. However, it is necessary to leave enough space around the equipment so that it 

is possible to access the fans in the event of their failure. Do not install the heat exchanger against a wall or an obstacle 

that prevents access to the fans.
In case of need to replace the fan, follow the following sequence:
• Remove the access panel for the affected fan (Fig. 1).

• Release the screws that lock the metal plate on which the fan is mounted (Fig. 2).

• Pull out the plate and once outside, remove the fan and proceed to replace it (Fig. 3).
