Installation and Operating Instructions

The air humidity is controlled through
the water moistened surface of the bla-
ded rotor and the water level in the tank,
respectively. As the water level rises, the
rotor blades are submerged more deeply
into the water, leading to a greater wet
surface area across the blades. The pas-
sing airflow absorbs moisture from the
wet blades, in accordance with a specific
reference value that is set as a constant.
However, as a rule the set relative humi-
dity is converted to the relevant absolute
humidity at 21 °C (factory setting) and
then controlled.

*) Set humidity (factory setting)
A prefiltering unit for the water supply,
which should be installed during the
course of mounting, is included in the
scope of delivery. As an additional safety
measure, the water is drained and an
error message output in case of the air
humidity is exceeded by more than 25%
of the reference value of the water for
longer than 25 hours.
