11.6 Installing condensate drain
310/410 320/470
NOTICE
Without a siphon, the ventilation unit will draw
in air through the drain pipe. Always install a
siphon (1½ ” external thread). Never fit several
siphons one after another without a pipe
divider.
NOTICE
Bacterial attacks are possible if a siphon is
fitted without a drip funnel as the siphon is
not then disconnected from the wastewater
system. Siphon needs seal water drop of at
least 50 mm. Install an open drip funnel with
another siphon at the drain end.
