When the light dot is centered fasten the four screws with the light dot still centered in the
cross hair. Once the screws are tightly fastened, remove the cross hair, flashlight and two
adapters. Remount the sensors with the transmitter and sensor electronics and connect the
sensor purging tubes.
The stability of the sensor alignment depends on the stability of the construction to which the
customer's flange is mounted. If the incinerator wall or smoke duct is subject to movements
due to, for instance, thermal changes CD 6C will need repeated realignment.
