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
DXA Unit and the distribution box.

EVACUATION OF CONDENSATES
To evacuate condensates, a lift pump may be used. It is also possible to use a siphon to
evacuate them by gravity, but a minimum slope of about 3° is recommended for the good
evacuation of condensates.
To ensure watertight connections between the condensate evacuation pipe and the lift
pump or the siphon, the DXA Unit is delivered with these components already built-in.
The DXA1712 is equipped with a lift pump, while the DXA1711 is equipped with a siphon.
Only the evacuation pipe to the wastewater has to be realized. This evacuation must be
insulated if installed outside the heated volume (risk of freezing).
Using the lift pump (DXA1712)
·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 DX System. Using
another lift pump can lead to serious problems of functioning and degrade the security of the
system.
All the connections must be watertight.
Using the siphon (DXA1711)
The condensate ducts must not be higher than the DXA Unit evacuation outlet
Before fixing the DXA Unit on the wall, the siphon has to be filled with 0.5 L of water. A funnel can
be used to realise the operation.
