Keep purging the analyzer once you install it on a stack.
Otherwise, the contamination of optical surface may result in the analyzer failure.
*1: When the flue gas contains a large amount of dust, ensure the minimum length of 50 mm.
*2: When the flue gas temperature is high (400°C or more), ensure the minimum distance of 400 mm.
Note that in that case you have to be even more careful in adjusting the angle of the companion flange
because the angle range
within which the companion flange can be adjusted is narrow.
*3: Make sure to install the analyzer in the place where it is easy to operate, and where there is enough
clearance.
*4: Scaffold is required for both the receiver unit side and the transmitter unit side.
*5: Use a flanged valve where there is a risk of gas blowout or where the operator may be exposed to a
dangerous situation.
*6: Tightening torque for the companion flange shall be 118±14 N·m. When tightening the bolts of the
flange or the angle adjustment unit, apply grease to the bolts. (Recommended grease is the one contains
molybdenum.)
