CAUTION

The Oil Water Separator Piping System may not produce a legally acceptable oil

free water effluent if the water contains soap, deter- gents, bilge cleaners, protein-

foam, or similar agents. The rated capacity of the system is the maximum flow

rate with clean filter elements and 0 psi back pressure.

CAUTION

Do not run water having temperature above 130 (55 ) through the OCA-1A

Sensing Module, as high temperatures may affect the accuracy of the PPM

reading.
