7.4. CONDENSATE DRAIN CONNECTION

A condensate tray is supplied with a 5/8" exterior diameter copper drain hole.
Ensure that the condensed water will drain properly from the tray, which must be connected to the main evacuation
pipe.
The evacuation pipe must be installed with a downhill angle. Check that the evacuation pipe work has a siphon
which must be made in accordance with the illustration below. Moreover, the evacuation pipe must be insulated
to prevent condensation forming on the outside of the pipe.
Check that there is no uphill section in the pipe run which might prevent condensate
evacuation.
All foreign bodies must be removed from the condensate tray.
Check that the condensates drainage hose is connected and allows liquid to drain freely.
Check that condensates actually drain properly (installation with or without drainage
pump) by pouring water into the condensates tray (pump electricity supply switched on).
Siphon for condensate evacuation
The height A must be equal to 2 times the value of the
negative pressure present in the condensate reception
zone
Example :
negative pressure = 40 mm
height A = 80 mm, height B = 160 mm.
