Note: On initial start-up, cell replacement or when brine plumbing connections are modified,
air is introduced to the brine line. This air must be removed for proper operation of the
brine pump. Air locks in the brine line will prohibit consistent brine flow to the cell.

Oxidant Discharge
The oxidant discharge connection from the RIO Series OSG is 1¼” schedule 80 CPVC but
increases in size to 1½”. The OSG is equipped with 1½” CPVC male union half. Proper
connection is accomplished with a 1½” CPVC female union half mating to the male half
(Figure 15).
MIOX supplies a three-way valve to allow for sampling of the disinfectant solution to verify
system performance. MIOX also supplies a check valve and strongly recommends installing
the valve on the oxidant discharge line. The valve should be installed between the RIO
Series OSG cabinet and the three-way valve sample port to prevent the backflow of
oxidant/hypochlorite into the electrolytic cell.
