·
If rigid ducts are used, the connection between the DXR Unit and the duct must be made
using a flexible sleeve (Ø160 mm), in order to avoid transmitting vibrations from the fan to
the duct.
-
Make sure that the flexible sleeve is not twisted or wrinkled and that it is correctly aligned
but not completely taut between the unit and the ductwork. To achieve this, it is essential to
have a constant section on either side of the sleeve.
-
To perform its function of decoupling between the components, the sleeve can be attached
by means of flat metallic clamping rings. It will then be necessary to make sure of the
airtightness of the assembly.
·
If flexible ducts are used, the connection can be carried on directly to the unit, making sure
that the connection is secure and tight with flat clamping rings and adhesive.
In order to fully guarantee the acoustic quality of the installation, it is necessary to
attenuate airborne noise from the main unit by:
·
20 dB at 500 Hz at supply
·
15 dB at 500 Hz at exhaust
This can be done using a silencer or an equivalent length of acoustic duct between the
DXR Unit and the DX Hub.

DUCT CONNECTION TO THE DX HUB 6
To connect semi-rigid ducts to the DX Hub 6, it is necessary to add a foam joint (supplied
with the DX Hub 6) on the 3
rd
groove.

EVACUATION OF CONDENSATES
Condensates must be evacuated to wastewater.
This evacuation must be insulated if installed
outside the heated volume (risk of freezing). It can be done by gravity with two siphons at the low
point, or using a lift pump like the one in the air conditioning unit.
Using a siphon
·Connect the evacuation pipe to wastewater.
·Before first starting up, fill siphons with water.
·Siphons must always be filled with water.
A slope of about 3° is recommended for the good evacuation of condensates. In any case,
manufacturer instructions must be followed. The evacuation pipe connection is in Ø16 mm.
The condensate ducts must not be higher than the DXR evacuation outlets.
Using a lift pump
·Connect the condensate pump to the DXR thanks to the metal pieces supplied in the condensate
kit.
·Connect the pipes using the metal sheet.
·A vertical height of 8 meters must not exceed between the lift pump and the evacuation duct.
Note:
The lift pump proposed by Aereco was tested and validated specially for the DX System.
Using another lift pump can lead to serious problems of functioning and degrade the security of the
system.
The lift pump connection is in Ø6 mm ID.
All the connections must be watertight.
