cessive, wherein the steam inlet and outlet pipe is
connected through pipe thread or flange, and the
connection type of steam inlet pipe is up-in and
down-out(→Fig. 13-1, 2).

3.6 Installation of siphon
For each of condensate pipes and overflow pipes,
one siphon must be applied. Several condersate
pipes sharing one siphon is not allowed. For the
installation of siphon please refer to Fig. 14
(siphon provided by the buyer or floating ball
siphon purchased from Bosch (optional).
When the MAHU is operating, U siphon will fails
when the unit is running dry. Due to the condition,
we recommend to use floating ball siphon (a self-
filling siphon for drainage of heat exchangers,
humidifiers, and other wet regions at a pressure
lower than ambient pressure, it contains a floating
ball which prevents the intake of air so that the
first accumulating condensate produced can fill
the siphon) for the alternative U siphon for the
problem mentioned below.
