The condensing water pipe must
have a downward slope.
The condensing water pipe must
never be connected directly to the
sewer.
It is not recommended to connect
a condensing water pipe to a water
seal or a floor drain where hot
wash or shower water goes.
(If hot wash water goes to the floor
drain and condensing water seal
gets dry during the summer,
steaming air is released from the
drain to the unit's negatively
pressured outlet side, which causes
water to condense from the air in
the pipe. A condensed water drop
may generate an audible sound
from the floor drain. The sound
may be generated in winter as well
if the water seal of the condensing
water pipe is not filled and does
not prevent air from flowing. Air
flow and the formation of water
drops in the condensing water pipe
should be prevented.)
The delivery does not include a
water seal nor the pipe and its
components.

Suction air
and filling
Normally to the floor
drain
May generate sound when
the water seal gets dry.
When there is no condensing water, the
water seal may get dry in 1 to 4 weeks.
To the water seal in
the wash basin
May generate sound
when the water seal
gets dry.
Normally to the floor
drain with a long water
seal
A long water seal ensures
soundlessness for a long
time.
Straight to the floor
drain without a
water seal
The downward slope of
the pipe is so steep that
a water drop generating
sound cannot remain in
the pipe.
Normally to the floor
drain
The pipe has a fork which
decreases suction from the
floor drain. No sound. Water
seal not necessary. The fork
can also be used to fill the
water seal if such a seal is
used.
Normally to the floor
drain through a
funnel
No water seal. No sound
because there is no
suction in the pipe. The
unit sucks replacement
air from the funnel.
Normally to the floor
drain through a non-
return valve
The valve prevents air flow
in the pipe but lets
condensing water flow into
the floor drain. No sound.
To the collector
No sound.
