Condensate drain
The ventilation unit produces up to 6 litres of condensate
per day. It is therefore important to mount the condensate
drain correctly. An ordinary Ø15 mm hose can be connected
directly to the ventilation unit.
It is important to make a loop in the hose to form a drain
trap with a minimum of 50 mm. Water column.
There must be a slope of 1% from the drain trap and the
hose towards the drain itself. If the unit is installed in a cold
environment, the condensate drain must be insulated to
prevent the condensate from freezing inside the pipe.
However, it is recommended that the drain trap is installed
in a heated area to ensure that the water inside does not
freeze.
If installation problems make it impossible to secure the
condensate drain against frost by means of insulation, it is
necessary to install a thermostatically controlled heating
wire around the condensate drain. During operation, the
unit experiences internal negative pressure. Therefore, it is
necessary to ensure a water column height of at least 50
mm in the drain trap under all conditions.
As ECO 275 may be used as a system configured for both
right and left facings installation – the machine is delivered
with a pre-installed plug inside the condensate drain that
will not be used.
Carefully tighten the included hose coupling nipple until the
O-ring seals against the head up into the thread connection
where no plug is fitted. Then the condensate drain hose can
be connected to the hose coupling nipple.
Check that the installation of the hose coupling nipple is
correct by pouring water into the condensate tray and
putting a finger on the outlet from the hose coupling nipple.
When having completed the installation – ensure that there
are no leakages.
