4.1. Unit body

The outer jacket of the heat recovery unit is made of high-quality plastic. The internal structure is made of monolithic
polypropylene, which serves as heat and noise insulation without thermal bridges. The orifices of the heat recovery unit
(∅ 150 mm) for air supply and exhaust are situated in its top part.

4.2. LED backlight

On the front side of the unit there is a colored LED backlight that provides a clear indication of the current status of the
unit. During normal operation, green color pulses on the unit in regular intervals. A change of the backlight color indicates
the need to replace the filters, error statuses and active Bluetooth. The meaning of individual colors is explained in table 2.

4.3. Filters and filter replacement

The heat recovery unit contains F7 filters at the air supply as well as exhaust. The necessity to replace the filters is indica-
ted automatically. The recommended interval of their replacement depends on the air quality in the environment where the
equipment is used (1× approx. 2 – 6 months). The basic filtration can be supplemented with an optional carbon filter, which
is inserted directly into the unit under the supplied air filter.
