Legal note
The guide includes notes that must be followed for your own personal safety as
well as to prevent damage to property.
Notes on your personal safety are identified by a warning triangle and use the
signal word CAUTION.
CAUTION identifies a situation that can result in slight injuries.
Notes dealing only with damage to property do not have the warning triangle and
use the signal word NOTE and an exclamation point.
The notes are depicted as follows:
CAUTION
Type and source of hazard
Consequences in the event the hazard occurs
●
Measures/prohibitions to prevent the hazard

QAA74 room units are suitable for:
lWall mounting, with wiring outlet under the surface.
lWall mounting, with wiring installed on the wall surface.
Please observe the following when selecting the installation location:
lPosition the room unit so that it is not exposed to direct sunlight.
lPosition the room unit in a manner that does not expose it to other heat
sources or sources of cold.
lPosition the room unit in an ergonomic manner. Select the appropriate
installation height (e.g. 150 cm about the floor).
lWhen installing, do not cover the inlet opening for the sensors integrated in the
units.
lEnsure that objects in the facility (drapes, door, etc. do not hinder the air flow
measured by the integrated sensors.
