J.3.6 Draining condensate water from plate heat exchanger
Condensate from the plate heat exchanger is collected in the drip tray. Heavy negative air pressure in this section pre-
vents 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 estimated correctly to
ensure safe escape of the water (see the illustration and estimate the minimum closing level according 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.
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.

This type of water trap for sections with negative pres-
sure and a ball that is sucked down into its seat for block-
age of air flow into the section is available from
Systemair. The above mentioned heights H1 and H2
are also valid for this type of water trap. The great ad-
vantage of this type of water trap for sections with nega-
tive pressure is that this type does not require water in
the bottom to close for air flow backwards into the sec-
tion. Condensate water will escape through this type of
water trap even after long periods without any water
to close for air flow backwards through the trap.
This water trap is optional and must be ordered sepa-
rately. Installation of water trap is not included.
J.3.7 Draining condensate water from cooling battery
If the cooling battery and the drip tray are placed in the unit where negative pressure (underpressure) occurs, the clos-
ing level of the water trap must be estimated correctly. See the above-mentioned information in J.3.6 Draining conden-
sate water from plate heat exchanger. If the cooling battery and the drip tray are placed in the unit where positive
pressure (overpressure) occurs, the closing level of the water trap must be estimated correctly as shown on the illustra-
tion below. A water trap is optional and installation of the water trap is not included.
