1.4 Filters
The heat recovery ventilation unit is equipped with M5 class filters at the inlet of the polluted air and F7 class filters
at inlet of the fresh air, to correctly protect the heat exchanger and guarantee optimum air quality inside the
building. However, the unit is originally delivered with a G4/F7 starter kit of filter. Once the unit has been running
for a few weeks, filters need to be replaced by a M5/F7 filters kit. F7 filters on both sides (supply & exhaust) are
available as an additional option.
Filters are the protectors of the heat exchanger, but also of the quality of the air you breathe. Check regularly
(once a month) the state of the filters. Vacuum the filters if necessary, and replace them when they are too dirty.
Clogged filters can create the following failures:
- Insufficient ventilation
- Excessive increase of the rotation speed of the fan creating excessive noise and power consumption
- A damaged filter allows 'dirty' air to enter the heat exchanger which will eventually clog the heat exchanger

datasheet recapitulating all the data useful for maintenance of the installation. Please keep a copy of this
datasheet close by as it may come handy for many reasons:
•
make a clear communication in case of discussion with the manufacturer
•
information if you need to change parameters when necessary,
•
this document can become an important factor in case of guarantee issues.
1.6 Warranty
The warranty of the manufacturer begins at the date of invoicing of PLC to the installer. The warranty is of 2 years,
except on the mobile parts where it is of 1 year.
