A.3 MAINTENANCE
Before each use, check that sufcient cleaning solution is present, at least 5 U.S. gal [19 L].
Periodically drain and replace the cleaning solution. The cleaning solution will depend upon what is
likely to cause the fouling. Your water treatment chemical supplier should be able to help you with a
recommended cleaning solution based upon your site-specic situation. The cleaning solution must be
compatible with the wetted materials of the cleaning system and the monitor. Do not select a cleaning
duration longer than the cleaning interval.
Make sure all threaded and tubing connections are tight and leak-free.
For extended shutdown ush the pump to prevent the uid from drying or freezing in the pump and
damaging the pump. The pump will be damaged by uid below 35 °F [4.4 °C].
The pump will need to be overhauled periodically depending upon amount of use. The overhaul period
cannot be predicted since the use time is not dened.
Before undertaking any maintenance and overhaul of the pump, shut off the sample supply and allow
the pump to operate until empty. Flush if necessary. Turn off power and uncouple power line to pump.
Remove pump from the mounting. Carry out all repair work with extreme cleanliness.
Turner Designs Hydrocarbon Instruments recommends you establish a preventive maintenance
schedule based on the pump’s service history. This is especially important for prevention of spills or
leakage due to pump head failure.
No expected maintenance of the automated valves or actuators is required.
A.4 TROUBLESHOOTING
PROBLEM CAUSE SOLUTION
Parts of the sample system,
including the ow cell and lines are
not sufciently cleaned during the
cleaning cycle.
Cleaning cycle duration is too
short.
Increase the duration of the
cleaning cycle. See Section A.2
Operating the Clean-In-Place
System.
Cleaning solution is not effective
upon fouling.
Use a different cleaning solution
appropriate for the mode of
fouling. Consult Turner Designs
Hydrocarbon Instruments for
recommendations.
Automated valves fail to switch
position during sample system
cleaning event.
Incorrect wiring. Check wiring connections at the
terminal blocks. See Section
A.6 E09 TD-4100XD General
Arrangement Drawings.
CLEAN key was not pressed, if
manually initiated.
If manually starting, press the
