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 1/4 turn
loose.
6. In this step, you will need to observe water flowing to the drain. If the drain flow is not
visible with the current tubing connections, install a temporary drain tube in the waste
port of the manifold. Turn on the supply valve. When water is seen flowing to the drain,
carefully loosen the capillary tube assembly retaining screws until the flow to the drain
increases.
Notice: When the assembly is about 3/16" out of the manifold, the o-ring seal for
the capillary tube is bypassed, but there should be no external leaks.
7. Rinse the manifold assembly for five minutes or until no chlorine is detected in the water
passing to the drain. Tighten the capillary assembly retaining screws.
8. Check the performance of the system according to the procedure outlined in the
"Performance and Technical Information" section of this manual. Replace the RO
membrane if necessary.
9. Instruct the customer to discard the first glassful of water from the system to flush out any
residual chlorine that might remain in the polishing filter tubing and faucet. The polishing
filter will remove any chlorine remaining in the storage tank.
10. Record your service on the chart at the end of the Owner's Guide.
