HOW TO INSTALL THE UNIT
The AR112C Air Quality Monitor is designed to sample and
determine the level of VOC gases in the room that it monitors. This
unit is for indoor use only.
As most VOC gases enter the human body through breathing, it is
recommended you mount or place it at eye level of the user using the
recessed mounting hole or retractable table stand.
For instance, if the unit is to be installed in the living room, it
should be installed at the eye level of a standing adult. If the unit is
to be used in the kid's room, it should be installed at the eye level
of the kid sitting on the bed.
