Connection to the water drain
Condensation water drains from the tray by
means of a flexible siphoned tube, which is fitted in the unit.
If the unit is fitted with a humidifier, the condensate drain tray
and the humidifier drain connection must be connected to
the drains of the building.
Direct connection to the drains of the building
Connect the drainage tube of the unit to the drains of the
building using a rubber or plastic tube with an internal diameter
of 25 mm.
The external drainage tube must be siphoned in order to avoid
unpleasant odours. Maintain a minimum slope of 1%
downstream of the siphon.

WARNING! The water discharged from the humidifier
is at a very high temperature. The drainage tube has
to withstand high temperatures (at least 100°C) and
must be kept away from electrical cables.
Connect the drainage tube of the unit to the collection tray
(U4) of the humidifier.
Connect the drainage tube of the humidifier (U7) to the drains
of the building using a rubber or plastic tube, which is resistant
to high temperatures (minimum 100 °C) with an internal
diameter of 22 mm.
The external drainage tube must be siphoned to avoid
unpleasant odours and an overflow of the water from the tray
of the humidifier.
