Servicing Your System (cont'd)
Filter Replacement and Sanitizing Procedure
Use the following procedure and the reference in Fig. 3 when servicing the Aqua-Cleer
Good Water Machine .
™
NOTICE: Cleanliness is essential in the filter replacement procedure. Be sure to wash your hands
thoroughly before handling filters. The use of protective gloves is strongly recommended.
Materials:
Pre-flushed activated carbon cartridge and polishing filter cartridge
Particle filter
Household (5.25%) bleach - hydrogen peroxide is not recommended
Clean 1-gallon plastic container with cap
100-ml graduated cylinder
Plastic pan to hold manifold assembly
Tubing connector, 3/8" tube x 3/8" tube
Flat-blade and #2 Phillips screwdrivers
Paper towels
Disposable plastic gloves (like those used in the food service industry)
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.
