DBV-(U)P 2.7
2.4.1 Pressure Equalisation
Rapid pressure surges within the airduct can, in 2-
clinder units, cause momentary imbalances in the
level control cylinder forcing the float beyond the
middle level sensor. At this point water is fed to the
system until it is stopped by the high level sensor
and all functions stop.
We therefore recommend the installation of a
pressure equalisation hose above the humidifier
between the two steam hoses.
»
Install the pressure equalisation hose just above
the humidifier between the two steam hoses.
2.5 Condensate Hose
Note: When installing the condensate
hose, please pay attention to the
following:
If the steam manifold is positioned higher than
500 mm above the steam humidifier:
»
Remove condensate plug from connection on the
cylinder.

connection
»
Lay the condensate hose with a slope of 5-10%
to the steam cylinder so that condensate can flow
back unrestricted.
Note: It is recommended to form a loop of
200 mm diameter as a vapour trap
provided there is enough space. Regard
also chapter 2.6. "Installation Examples".
Possible operating noises can be reduced
in this manner.
If the steam manifold is positioned lower than
500 mm above the steam humidifier:
»
Let the condensate flow into a drain.
»
In order to avoid steam losses, a loop of at least
200 mm diameter should be formed.
»
The loop in the condensate hose should be
located away from the steam manifold
connection.
»
Ensure that the condensate connection on the
steam cylinder is closed with a plug.

Use hose clips at intervals of approx. 500 mm
depending on type of hose.
2.6 Installation Examples
If the steam manifold is positioned higher than
500 mm above the steam humidifier:
»
Lay the steam hose at a height of at least
400 mm above unit and then connect to the
steam manifold with a constant rise or fall.
»
Lay condensate hose with a slope to the steam
cylinder.
