DESCRIPTION AND THEORY OF OPERATION
THEORY OF OPERATION
Product Flow Element FE-501 (mounted in the piping) and Product Flow Transmitter FT-501 (mounted in
the instrument/solenoid panel; see Figure 5) measure product flow. This flow is displayed at the OCP.
Product Utility Valve V-511 is used for filling chemical buckets and general use.
Hypochlorite Injection Check Valve V-633 injects a measured amount of calcium hypochlorite into the
product water flowing to the product water distribution system. This chemical chlorinates the product
water to kill and prevent the growth of algae and bacteria in the product water. (See Chemical Injection
System for further explanation.)
Product Water Check Valve V-512 prevents the flow of chlorinated product water back into the RO when
not in operation.
Four 10-ft. sections of blue-banded suction hose are connected to the product water outlet to discharge
product water to a distribution tank.
