1) Close the feed water tapping valve and lift up on the faucet
handle to empty the water in the storage tank. It should
feel light when empty.
2) Shut off the faucet and close the valve at the top of tank.
Disconnect the 3/8" yellow tubing from the back for the
purification assembly. (Refer to Fig. 6 on the use of the
special "Push-In" connectors.) Remove the tank from its
location and drain it into the sink by turning it upside down
and opening the valve. Make sure that the outlet fitting is
pointing away from your face and into the sink.
3) Make sure that the feed water tapping valve is completely
closed and disconnect the 1/4" orange feed water tubing
from the purification assembly. Connect the end of the
feed water tubing to the sanitizing device. Connect an
extra length of 1/4" tubing to the other end of the sanitizing
device. Using the 3/8" x 1/4" union connector, connect the
3/8" yellow tubing from the tank valve fitting to the extra
piece of 1/4" tubing. (See Fig. 9)
4) Fill the sanitizing device with the following recommended
dosage of common household bleach:
•
A standard 2.5 gallon tank - 1/2 teaspoon (3 ml)
• Alternate size tanks - 1/2 teaspoon (3 ml) per 2.5 gallons
of tank capacity
5) Open the feed water tapping valve to force water and
sanitizer into the storage tank. Allow about three (3)
minutes to fill a standard 2.5 gallon tank. It should feel
heavy when it is full.
6) The sanitizing agent should remain in the storage tank a
minimum of 15 minutes. Close the feed water tapping valve
and the storage tank valve. Disconnect the sanitizing device
from the storage tank and feed water tapping valve.
Reinstall the storage tank and reconnect the 1/4" orange
feed water tubing and the 3/8" yellow tubing.
7) Open the feed water tapping valve to pressurize the system.
Open the tank valve and lift up on the faucet handle to drain
the storage tank of the sanitizing solution. When the storage
tank is empty, the faucet should drip steadily.
8) Shut off the faucet and allow the storage tank to fill for at
least six (6) hours. Drain the storage tank again and discard
the water. The appliance should be ready to use as soon as
the tank refills. If any objectionable taste is noticed, then
drain the storage tank again and allow it to refill.
How to Sanitize the Purification Assembly
Sanitizing the Purification Assembly generally requires:
• A new prefilter cartridge
• Common household bleach (5.25% non-scented)
• A standard eyedropper or equivalent
1) Close the feed water tapping valve and lift up on the faucet
handle to empty the storage tank.
2) Follow the instructions on changing the prefilter cartridge.
3) Before installing the new cartridge, use and eyedropper to
inject one teaspoonful (approximately 5 ml) of household
bleach into the center opening of the filter cartridge. The
prefilter is located just before the RO membrane cartridge.
(See Fig. 10)
4) Open the feed water tapping valve and allow the appliance
to operate for at least six (6) hours. Drain the storage tank
and discard the water. The appliance should be ready to
use as soon as the storage tank refills. If any
objectionable taste is noticed, then drain the storage tank
again and allow it to refill.
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 feed water tapping valve. Wait five minutes for
the purification 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: The cartridges
must be not be allowed to freeze because permanent
damage may occur.
4) When the RO appliance is ready to be put back into serv
ice, reinstall the filter cartridges by matching the symbols
on the top of the cartridge labels with the ones on the
purification assembly heads. Sanitize the storage tank as
described in the previous section. The purification
assembly can be sanitized at this time if so desired.
5) Follow the start up procedure outlined in the previous section.
