INSTALLATION
08354A DCN7303
The ASC requires an inlet nozzle and an adapter for installation. The black inlet
nozzle to the optical sensor is specific to the instrument (not interchangeable to
other T640 instruments). The final assembly differs slightly between the T640
ASC and the 640X Option ASC.
1. Insert the black inlet nozzle through the center of the support collar into the
top of the optical sensor, seating it tightly so that the nozzle's upper o-ring
flange is flush with the upper surface of the sensor body.

2. Slide the aluminum adapter over the black inlet nozzle, ensuring its base is
flush with the top of the optical sensor.
