Sanitizing the Reverse Osmosis System

Safety

Sanitize upon installation of the Reverse Osmosis system and after servicing inner parts, including replacement of prefilter, postfilter and the membrane cartridge.

Be sure to wash your hands before handling inner parts of the system.

CAUTION: Before sanitizing, be sure to remove all cartridges. Chlorine will destroy the Reverse Osmosis membrane cartridge.

1.Follow steps 1 through 4 under Prefilter, Postfilter and Reverse Osmosis Membrane Cartridge Replacement Procedure.

2.Fill the empty canister labeled “Sanitization Canister” with water to within 1 inch of the upper opening. Add 1 oz. (2 Tbsp.) ordinary household bleach. Install canister into the prefilter canister position by turning to the right about 1/3 turn until the alignment marks line up and the canister stops.

4.Turn ON water supply. Turn ON faucet until water begins to flow from the faucet, then turn faucet OFF. Allow system to fill for 10 minutes.

5.Turn faucet ON and allow water to flow for 20 minutes, or until bleach odor is gone. Turn OFF water supply again. Turn ON faucet to drain the system.

6.Once the system is drained, turn the faucet OFF and remove the canisters by turning to the left about 1/3 turn. Keep these in a safe place until needed the next time.
