CAUTION: Read “WARNINGS” information on bleach container
before using contents. Handle sanitizing solution carefully. Avoid
contact with unprotected areas.
13. Mix sanitizing solution of 1.5 ml (1/3 teaspoon) of household bleach and 3.8 L
(1 gallon) of clean, potable water in the bucket. Mix solution well.
Note: Excessive concentrations of bleach (sodium hypochlorite) may damage plastic and rubber
components. Rinse all parts that contact bleach thoroughly with clean potable water.
14. Add 236 ml (one cup or 8 oz.) of sanitizing solution to each filter housing and install
them onto the manifold (do not install filters or membrane at this time). Tighten
each filter housing by hand only.
Note: Tighten filter housings by hand only. Do not use tools as they will over-tighten and
damage housings.

16. Close product water faucet as soon as water begins to flow from spout.
17. Wait 5 minutes, then close source water supply valve.
18. Wait 25 minutes, then open product water faucet. Let water flow to drain until
system is drained (flow stops), then close faucet.
Note: Remove filter housings only after water flow stops.
19. Remove filter housings and dispose of water. Rinse housings/manifold thoroughly
with clean, potable water.
Note: Do not remove protective plastic bag from replacement filter and membrane cartridges.
Note: For optimum monitor performance, the monitor must be re-set and the battery replaced
each time system is sanitized. However, a technician may wait until indicator lights fail to illumi-
nate to replace battery.
