Duct Installation: Surface Preparation
The following instructions are applicable for both the light source unit and
the detector unit (see Figure 8)
:
➢
To prepare the surface:
1
Check the air duct installation surface (1) stability. It should be as
near as possible to a rigid girder connection in order to assure proper
support to the mounting and the unit. Also the surface must be stable
and free of vibrations.
1
Locate the best installation surface for the detector/light source. The
location of the central point of each duct hole (3) should be at the
same distance from the surface edge. This will provide that both
detector and optical axis will be parallel to the air duct wall lines such
that any blocking in the interior area will be prevented.
2
Preparation of the surface: Prior to hole drilling, you should verify that
the installation surface is straight, clean, and free of corrosion.
3
Drilling and cutting: Mark the location and dimensions of the
installation.
Figure 7 shows surface drilling dimensions. Drill the duct hole (3) and
the screw holes (2) carefully.
Caution:
Since the installation is done in a potentially explosive
atmosphere, any workmanship in the installation area should be
performed under the appropriate rules and regulations.
