SANITIZING THE STORAGE TANK AND FAUCET
1. Add 15 ml (about one tablespoon) of bleach to the particle filter housing (#1,
Fig. 3). Replace all three housings on the manifold and insert the u-clips.
2. Turn on the supply valve and fill the storage tank with 1 to 2 gallons of water.
NOTICE: The weight of the storage tank will increase by 8 to 16 pounds. Turn off
the water supply valve.
3. Wait ten minutes before opening the faucet and draining the storage tank. Do not
rinse any remaining solution from the tank.
NOTICE: During this time, proceed to the "Sanitizing the Manifold Assembly" section.
Wait to do step 4 until indicated.
4. Remove the temporary tubing connector and replace it with a new polishing filter.
Make sure the flow arrow on the polishing filter points to the faucet (Fig. 4).
SANITIZING THE MANIFOLD ASSEMBLY
1. Using the flat-blade screwdriver, pull the u-clips from all three housings. Insert the
u-clip into the two square holes at the bottom rear of the manifold and push up to
release the filter housings. Remove the housings with a downward twisting pull.
Discard any solution remaining in the housings.
2. Open the particle filter cartridge bag half way, being careful not to touch the filter
element. Lubricate the particle filter cartridge o-rings with water and insert the
cartridge into position #1 in the manifold.
3. Fill housing #1 about 2/3 full of the diluted bleach solution from the 1-gallon
container. Assemble the housing to the manifold and replace the u-clip.
4. Repeat steps 2 and 3 for housing #2 (activated carbon cartridge) and housing #3
(RO membrane filter).
NOTICE: For RO membrane filters that have a single open-end, pour diluted bleach
solution into the center tube.
CAUTION: The solution should remain in contact with the RO membrane filter
for at least five (5) but no longer than ten (10) minutes. Longer contact time will
shorten the life of the membrane.
NOTICE: While waiting for the filters to be sanitized, complete step 4 of the "Sanitizing
the Storage Tank and Faucet" section. Then complete step 5 below.
5. Using the #2 Phillips screwdriver, loosen the capillary assembly retaining screws,
then twist and remove the assembly. Inspect the tubing for plugging and kinks and
replace the tubing as needed. Reinstall the capillary assembly, but leave the screws
¼-turn loose.
