How to Sanitize the Storage Tank and Filtration System
Sanitizing the storage tank generally requires:
•
Common household bleach (5.25% non-scented)
•
Eye dropper or plastic oral syringe
1) Close the cold water feed valve and lift up on the faucet
handle to empty the water in the storage tank. It should
feel light when empty.
2) Disconnect the 3/8” yellow tubing (system tank) from the
ball valve on top of the storage tank.
3) Insert into the yellow tubing 1/2 teaspoon (3 ml) of house-
hold bleach. (See Fig 9)
4) Reconnect the yellow tube to the tank ball valve.
5) Close the RO faucet and open the cold water feed valve.
6) Wait 4-5 hours.
7) Lift up the handle of the RO faucet and allow contents of
tank to drain completely into the sink.
8) Sanitizing is now complete.
9) If there is any residual chlorine/bleach taste in the next tank
full, drain tank completely a second time.
E. LONG TERM NON-USE
If the RO appliance is to be left unused for a long period of
time (greater than 30 days), follow this procedure:
1) Lift up on the faucet handle to drain the storage tank and
close the cold water supply shut off valve. Wait five min-
utes for the filtration assembly to depressurize.
2) Remove all of the filter cartridges. Turn the cartridges
upside down in the sink to drain out as much water from
them as possible.
3) Place the cartridges in an air tight plastic bag and store
them in the refrigerator.
IMPORTANT NOTE:
The cartridges must be not be allowed to freeze because
permanent damage may occur, which may result in property
damage due to water leakage.
4) When the RO appliance is ready to be put back into ser-
vice, reinstall the filter cartridges by matching the symbols
on the top of the cartridge labels with the ones on the
filtration assembly heads. Sanitize the storage tank as
described in the previous section. The filtration assembly
can be sanitized at this time if so desired.
5) Follow the start up procedure outlined in the previous
section.
