OPERATOR INSTRUCTIONS
MAINTAINING NORMAL OPERATION UNDER USUAL CONDITIONS
6. Note the position of the module for identification.
a. If more than two are leaking, isolate the two with the most noise.
b. Continue operation. Notify unit maintenance to replace the damaged MF elements or O-
rings.
1) If the leakage noise is only at the top or bottom of a module, the problem is
most likely a damaged O-ring.
2) If the leakage is observed along the column, the MF element probably requires
replacement.
c. Set the MF Test Switch to OFF after completing the sonic test and isolating the damaged
MF modules.

RO ELEMENT PRODUCT FLOW AND CONDUCTIVITY TESTS
A product TDS high alarm at startup and a TDS reading that does not drop below 1000 mg/L after a few
minutes of operation is an indication of a damaged RO vessel O-ring or RO element failure. If you get a
high TDS alarm, perform a conductivity test and correct as indicated.
RO product water flow and conductivity tests are also performed at the beginning of deployment and after
500 hours of operation. Product water flow tests and conductivity tests are typically performed at the
same time. The product water flow test is performed for a given element first and is immediately followed
with the conductivity test for the element.
