The following maintenance interventions must
only be carried out by the installer or by qualified
personnel:
• Inspect the filters and clean them if necessary;
• Inspect the heat exchanger and clean it if nec-
essary;
• Inspect the fans and clean them if necessary;
• Check the condensate drain once every two
years.
The following paragraphs have a short descrip-
tion of the maintenance interventions.
PLEASE NOTE: If maintenance is not carried out
regularly, the ventilation system might not work
properly.
• Check the heat exchanger
Always disconnect the power
before accessing the unit.
Check the heat exchanger once every two years.
• Use a screwdriver with TORX head to remove the
heat exchanger panel cover.

port the panel “2” in the way that it does not fall
down.

• Inspect the condition of the heat exchanger and
clean it if necessary:
- Use a soft brush to clean the fins.
- Use a vacuum cleaner or compressor (not high
pressure) to remove debris and dust.

rection of the air flow.
- If no other operation is necessary, put all the
components back in, in the opposite order and
reconnect the power.
