Instruction Manual Rev B
Installation – Mechanical
A review of the drawings and procedures provided will help to produce an error free installation. However, there are
important additional points that must be observed. The beam of the instrument must be kept in the horizontal plane;
the transceiver cannot be rotated more than +/- 10 o from vertical. The weather covers must be installed vertically
plumb.
Installation and wiring diagrams are
found at the end of this manual. Please
review all drawings prior to starting
installation or wiring. If you have any
questions please contact our Customer

Installation procedure - stack
flanges
For an opacity monitor, the customer is
required to supply and install two 3" I.P.S.
flanges at eye level directly across from
each other. The flange faces, mounted on
pipe stubs, should be approximately 6" to
8" from the stack or insulation.
On
completion of the installation, the flanges
must be aligned so that the total
deviation of the light source flange
relative to a common centerline, does
not exceed +1 o and the retro reflector
flange does not exceed +3 o .
Flanges should be mounted approximately 5 feet up from the deck of platforms, roof or walk way.
At installations where conditions permit, this may be accomplished by using a piece of 2 1/2" pipe suspended across
the stack protruding far enough to allow slipping the 3" flange pipe assemblies over each end and welding in place as
shown on the following page.
Any deviation up to the previously specified limits can be adjusted out during the installation and alignment of the light
source and retro reflector with the system's alignment adjustments.
