I.4.5 Droplet eliminator access to removal and cleaning
Inspection door is installed in the air handling unit for easy
access to removal of the droplet eliminator for cleaning
outside the unit of the droplet eliminator on both sides. If
the droplet eliminator is the last component upstream in
the airflow of the air handling unit and no inspection door
is installed in the air handling unit, an inspection door
must be installed by the installer in the duct system. The
droplet eliminator is easy removable from the air handling
unit. Lift the drop eliminator 2 3 cm to move the under-
side of the eliminator over the bottom profile lower the
eliminator to the floor of the unit, and the eliminator is
free of the upper profile. Hereby the eliminator is released
for easy withdrawal and cleaning outside the unit.
I.4.6 Draining condensate water
Drip trays for collection of condensate water are installed under plate heat exchanger, run-around coil and cooling coil.
Each drip tray is provided with a drainage outlet. A water trap is always necessary. To avoid freeze ups and frost bursts
of water trap and pipes, sufficient insulation is recommended and installation of heating between the insulation and
water trap/pipes could even be necessary (insulation, heating and controller for the heating are not delivered by
Systemair).
I.4.7 Video instruction draining condensate water from heat exchanger
Condensate from the plate heat exchanger or run-around-coil is collected in the drip tray. Heavy negative air pressure
in this section prevents the water from flowing out of the drainpipe. A water trap with sufficient closing level of the
water is essential to ensure that condensate water flows out of the unit. The closing level of the water trap must be es-
timated correctly to ensure safe escape of the water (see the illustration and estimate the minimum closing level ac-
cording to the table).The pipe diameter of the water trap and sewage system must be identical to the pipe diameter of
the drainage outlet from the tray.
Note:
Instructions about easy, quick and safe assembly and cleaning of water trap is displayed in a 2–minutes
video. The video is available on YouTube.

Remember to check that there is water in the water trap.

Necessary closing level that is H1 minus H2 for exam-
ple for the negative pressure 500 Pa equal to 50 mm
of water column is 60 mm because the 50 mm corre-
sponds to the negative pressure is lifting the water 50
mm and an excess height of 10 mm enables the water to
flow out through the water trap into the sewage system.
With the negative pressure at 750 Pa, an excess height of
20 mm enables the water to flow out through the water
trap into the sewage system.
