Sanitizing
We recommend sanitizing the system at least once a year. This can be done while changing your filters. Shut
down the system. If you have an icemaker hook-up installed, be sure the ball valve in the line to the
refrigerator is in the closed position during this procedure. Open the faucet to drain the system, including the
tank. Remove the pre-filter cartridges and RO Membrane from the system, leaving the old post-filter cartridge
in place. Wash the internal filter housing & membrane housing areas with warm soapy water and rinse well to
remove the soap. Pour about ¼ teaspoon of Hydrogen Peroxide or household bleach into each filter housing
and replace housings on the RO system. Open the feed water valve and open the RO faucet until water flows
freely from the spout. Close the faucet and hold the solution in the system for a minimum of 10 minutes.
Drain the tank completely, close the faucet to allow tank to fill again, and then drain again. Replace filters and
membrane as indicated in the replacement instructions. The post filter should be changed after sanitizing the
system. Repeat the “Turning the System On for the First Time” procedure (page 13.)
*Note: It is recommended to chemically disinfect the entire distribution system located after the UV. To
ensure water being routed to external equipment is microbiologically safe and does not contaminate the water
in the system, this equipment and leading plumbing must be disinfected according to manufacturer’s
instructions.
