4.7 Condensation extractor
The HRC must always be fitted with a condensation extractor underneath the unit.
It is preferable to use a dry siphon (article number: 22700065), which can be ordered
separately. Because this requires less space underneath the unit, there is less chance
of air leaks and it does not dry out on hot days, which prevents odour issues. When
connecting the siphon, always use PFTE tape to prevent leaks.
Standard siphon
The unit is supplied with a standard 32 mm connector with threaded end. This can be
connected to the bottom of the unit on internal thread (G1 ¼"). The condensation water
must be extracted through the inner sewer system free of frost and on a slight incline.
A water trap of at least 80 mm must be installed to prevent an air leak and sewer
odour from spreading into the ventilation system. A siphon with a diameter of 40 mm
must be placed under the water trap. Preferably use a threaded connector and rubber
gasket for easy cleaning of the siphon. When connecting the siphon, always use PFTE
tape to prevent leaks.
