10. Replace the rotating arm assembly back onto
the motor shaft and tighten the set screw on the
flat of the motor shaft.
11. Replace the blue-ribbon cable.
12. Replace the flow cell being careful the flow cell
is properly aligned before lowering the toggle
clamp, as shown in Figure 14.10.
13. Make sure the toggle clamp is pressed all the
way down and the ¼” tubing is reconnected
before starting the water flow again.
14. Check for leaks. If a leak occurs, immediately
shut off the water supply and drain the flow cell
and then reinstall it.
15. Power the monitor.
16.
Close the door and watch the “Secondary Data”
entry in the main menu to make sure raw sensor
values are at expected levels.
Note:
W and L values should be between 2000 and
3500 with DI water in the flow cell. These values will
increase as the UV lamp warms up and so these
values should be checked several minutes after the
UV lamp turns on. If the raw sensor values do not
reach the levels indicated, or they are too high, then
contact Chemtrac, or your supplier for assistance.
