Automated Fluorometer Cleaning System
Some process waters will leave deposits within the fluorometer which can lead
to cell fouling and inaccurate readings. The fluorometer can be cleaned using
the automated fluorometer cleaning system, which is composed of three
separate parts:
•
121-P01152.88, Solution pump
•
001-H04066.88, Containment basin for cleaning solution
•
460-S0340.11, Cleaning solution, Nitric/Phosphoric acid, 5 gallons
(order cleaning solution separately.)
To attach the fluorometer cleaning system, connect the pump outlet to the
t-fitting located between the solenoid valve and Fluorometer. Pump ships with
a 3/8" check valve which threads directly to the t-fitting. Connect the pump and
solenoid valve power cords to the pigtails pre-wired to relay 5.
IMPORTANT
: Prior to physical cleaning of the fluorometer, close ball valve beneath
fluorometer and set relay #5 to manual off (through keypad press
Actions>Manual
Relay Control>Relay #5 (S0340) >Current State>Edit>Manual Off>Accept
.)
Press
Auto After
then
Edit
to select amount of time the relay will remain in selected
mode prior to reverting back to auto. Open ball valve when finished with cleaning.
