INSTALLATION

3.1. LOCATION OF THE INSTALLATION

The unit must be installed into the heated space, in parts of the dwelling relatively 

insensitive to noise, not in the unheated space (attic, etc.). Upper and lower 

temperature limits for the main unit are 5°C and 50°C 

Ductwork should be installed in the heated space. If not, they must be insulated 

with 50 mm minimum of glass wool (or equivalent). The non compliance with these 

conditions leads to the degradation of the heat recovery performance.

DXR Unit

Max. altitude of the product installation

2000 m

Temperature range of the installation place

5°C – 50°C

Humidity range of the installation place

5 % - 95 %

3.2. DXR UNIT

The caps on the DXR Unit must stay during the entire duration of the work, in order to 

keep dust and pollution from getting into the boxes.

3.2.1.  LOCATION

Before the installation, be sure of the solidity of the ceiling where you plan to install DXR 

Unit.

 ·Weight of DXR Unit = 46 kg

The DXR Unit must be attached so that the gap between the ceiling and the top of the unit 

is at least 10 mm, and positioned exactly horizontally (max 1° tolerance).

The non compliance to this requirement may lead to serious problems of condensate 

evacuation.

Positionning of the DXR Unit
