H1 must be shortened on the site by the installer
sometimes to only 100 mm because the height of the
low version of the base frame is only 118 mm. The ad-
justable length of H2 must be reduced to the minimum of
40 mm. According to the values in the above table, this
allows Water to flow out at a negative pressure up to 500
Pa because the closing level that is H1 minus H2 is 60
mm with 50 mm corresponding to the negative pressure
lifting the water 50 mm and an excess height of 10 mm
that enables the water to lift the ball and to flow out
through the water trap into the sewage system.
To avoid freeze ups and frost bursts of water trap and
pipes, sufficient insulation is recommended and installa-
tion 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).
The insulation must be easy to remove above the cap, be-
cause the ball and the seat for the ball must be cleaned
regularly to allow the ball to close air-tight to the seat.
H.4.7 Draining condensate water from cooling coil
If the cooling coil and the drip tray are placed in the unit where negative pressure (underpressure) occurs, the closing
level of the water trap must be estimated correctly. See the above-mentioned information in H.4.6 Draining condensate
water from heat exchanger. If the cooling coil and the drip tray are placed in the unit where positive pressure (overpres-
sure) occurs, the closing level of the water trap must be estimated correctly as shown on the illustration below. A water
trap is optional and installation of the water trap is not included.
Remember to check that there is water in the water trap.

I Installation and assembly instructions for reduction of noise and vibration
emissions
Due to the design and construction of the units the (A) weighed sound pressure level from fans and other components
do not exceed 70 dB (A) outside the units.
Data about sound in Annex 2.
Installation of the units on springs will reduce the transmission of noise and vibrations to the building. Systemair does
not deliver springs for this purpose.
