BEFORE START UP

You must complete the following before start up is attempted.
Measure and record flange -to-flange distance to verify it is the same as final check out sheet.
1.
If you are using a recorder, DAS, etc.,
2.
other sources should be left off until system has been completely checked according to the following
instructions. After system operation has been verified connect and test external connections.
Read the instructions first to familiarize yourself with the instrument before attempting start up.
3.
The air purge and Weather cover system, Transceiver, Retro reflector, Service module must be
4.
installed and power applied.
Control unit must be installed and wired to the service module and customers equipment as
5.
applicable.
All wiring and mechanical installations must be complete per drawings provided in this manual. All
6.
wiring must be checked and power applied to both the control unit and the stack maintenance
module.
Beam Alignment procedure has been completed.
7.
STACK EXIT CORRELATION COMPUTATION
The stack exit correlation is especially important to verify. If possible all dimensions should be verified
1.
by actual measurements.
Measure and record inside stack dimensions at the measuring point and at the stack exit, and compute
2.
the Optical Path Length Ratio (O.P.L.R.) Check that the calculated and the O.P.L.R. found in the
Factory OPLR Check step found further in this section are with in +/- 2%.
 Lx = Stack exit inner diameter, Lt = Inner diameter of the effluent path
 Example: A stack
