3.2.4. DUCT CONNECTIONS TO THE DXR UNIT
AND TO THE DX HUB
The connections to the DXR Unit are all in Ø160 mm. Labels on the unit identify the 4 ducts to be
connected (fresh air, used air, supply air, exhaust air).
Outdoor fresh air and used air ducts must
be insulated.
Be careful to respect top and bottom of the installation.

Labels on the unit identify the 4 ducts to be connected (fresh air, used air, supply air, exhaust air).
Either on the DX Hub 5 or on the DX Hub 6, it is possible to choose one inlet among a
choice of 2 (DX Hub 5) or 3 (DX Hub 6).
Firstly the foam has to be cuttered then the metal part can be swinged in order to remove
it. Then as the assembling part of the DXR's spigot, the inlet spigot has to be screwed
and sealed to the DX Hub.
The seal can be made thanks to silicone seal.
