1.3 About the counterflow AIR/AIR heat exchanger

Protect the heat exchanger by regularly cleaning or replacing the filters.
To protect from frosting, the TAC5 DM control includes an antifreeze system by unbalancing the in and out
airflows.
The HRmural units are specified not to exceed a frontal air speed on the heat exchanger of 2,5m/s.

1.4. Filters

Residential-type 450 units are delivered with G4 filters on supply and exhaust air. F7 filters can be delivered in
option.
In the other cases, the heat recovery ventilation unit is equipped with M5 class filters at the inlet of the polluted air
and 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/G4 starter kit of filter. Once the unit has been running
for a few weeks, filters need to be replaced by a M5/M5 filters kit. F7 filters on supply 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

1.5. Installation control datasheet

When the installation is completed and running, we strongly advise that the installer fills in the installation
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.
The warranty is limited to the replacement of the defective parts, and does not include labor and traveling
expenses. The warranty becomes void if:

The installation is not accomplished according to the prescriptions described in this above.

Repairs were carried out by unqualified staff.

The startup control datasheet (see appendix) is not filled in properly and not made available when claiming
