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.

5.25% Bleach

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.
