Preparation
1. Locate the system's supply valve and turn off the system's water supply.
2. Using the graduated cylinder, add 5 ml (about 1 teaspoon) of bleach to the 1-gallon
container. Open the dispenser faucet and fill with one gallon of product water. If there
is not enough RO water, fill the container the rest of the way with soft water. Cap the
container and shake to mix.
Notice: If any RO water remains after filling the container, you may want to fill a
pitcher with the drinking water as it will take several hours for the system to refill after
servicing. In any case, leave the faucet open until the storage tank is empty and then,
close the faucet.
3. Remove the polishing filter (Fig. 4) and discard. Connect the tubing ends together with
the tubing connector.
4. Lift the filter assembly from the mounting bracket and place it in the plastic pan to catch
any dripping water.
5. 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.
6. Remove the particle filter cartridge and the activated carbon cartridge and discard. If the
RO membrane filter will be reused, clean the outside with a wet paper towel and place
the membrane filter in a clean, unused plastic bag.
7. Wet some paper towels with the diluted bleach solution. Clean the inside of the housings
and the underside of the manifold with the paper towels.
Sanitizing the Storage Tank and Faucet
1. Add 15 ml (about one tablespoon) of bleach to the particle filter housing (#1, Figure 3).
Replace all three housings on the manifold and insert the u-clips.
Notice: The weight of the storage tank will increase by 8 to 16 pounds. Turn off the
water supply valve.
2. Turn on the supply valve and fill the storage tank with 1 to 2 gallons of water.
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 (Figure 4).
