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.
