4.1 Condensation outlet
4.1.1 Establishment of condensation outlet
The connection must be made by an authorised plumber.
The execution of the condensation outlet must take into consideration
that the doors must be able to be opened, and that inspection, servicing
and operation of the air handling unit should be unhindered.
A water trap must be established from all sections with an outlet.
4.1.2 Water trap
Water trap is supplied as an accessory.
Water traps are either designed for negative pressure or overpressure and are fitted a
ball to preserve their water tightness even when not filled with water. The water traps
are connected to the base trays drains in the sections with drains.
The drain is Ø32 mm on the exterior.
The next drawing shows an example of how the drain for the condensate from the
condensation outlet can be established, and the correct dimensions for the water trap.
To achieve sufficient height, it may be necessary to fit the air handling unit on levelling
screws, or where possible, make space down in the surface/floor.
It is recommended that the water trap is fitted to its full length, however, the pipe can be
shortened if required, if the water trap is too high.
The outlet from the water trap is led to the drain with a gentle incline. The drain pipe must
end above an open drain. There must be a water trap for each base tray in the air
handling unit. Several water traps can be connected on the drain, with a gentle incline
on all of the drain pipes. Max. negative pressure for a water trap for the air handling unit
is 1200 Pa. If the water trap is trimmed, the capacity falls by 10 Pa/mm.
For correct and problem free operation, it is recommended that a Siphon water trap is
fitted. This also applies to outdoor versions of air handling units.
If a Siphon water trap is not used, the water trap must be executed in accordance with
the dimensions shown below.
Frost protection of
water trap
SIPHONE electrical heat tracing.
It is recommended to protect the condensation outlet against frost damage by fitting a
SIPHONE electrical heat tracing device on the outlet before the pipes are insulated. For
fitting, see the device’s fitting instructions.
