R.O. systems produce drinking water at relatively slow rates; it can take up to 6 hours or more to fi ll the Holding
2.
Tank. Normal operation is to let the Holding Tank fill with water and then draw water as needed. When the pressure
in the Holding Tank falls to a given pressure (as the water is being used) the Automatic Shut–Off Valve (ASO Valve)
will start water production and the system will refill the Holding Tank. When the Holding Tank is full and no water is
being used, the ASO Valve will automatically shut off the feed water to conserve water. The more water that is used
(up to the capacity of the system) the better the R.O. system will function. Other uses for the water are flowers, pets
and rinsing glassware. With each use it is recommended that you run the tap for at least 10 seconds prior to using
water. This is especially important if the water tap has not been used daily. After periods of non–use, such as a week
of vacation, it is better to empty the Holding Tank and allow the system to produce fresh wa ter for use. If the system is
not used for 3–4 weeks or longer, it is a good idea to resanitize the system and to change the prefilter and postfilters.
B.
Changing Filters
THIS RO SYSTEM CONTAINS FILTERS WHICH MUST BE REPLACED AT REGULAR INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY APPROVED FILTERS.
All individuals should take adequate precautions when changing the filters, including wearing protective gloves,
to avoid direct contact with the exhausted filters. The recommended interval for changing the filters (not the RO
Membrane) is every six (6) months. Typical T.F.C. Membrane life expectancy is three years. Local conditions may
dictate more frequent changes.
NOTE: If the RO Membrane is to be replaced, see page 11, for the proper procedure. Use a drip pan to catch any
water that may spill when the Filter Housings are removed. Refer to Fig. 1 page 5 for component location.
Close the Feed Water Saddle Valve by turning fully clockwise and open the Dispensing Faucet by lifting the
1.
handle. Allow the Holding Tank to empty.
Loosen and remove the Sediment/Carbon Filter and the Activated Carbon Filter Housings. Discard the filters.

3.
Wash the inside of the Housings using a mild detergent and a soft cloth. Do not use abrasive cleaners or pads.
Thoroughly rinse all soap from the Housings before reassembly.
4.
To sanitize the system and replace the filters:
NOTE: The system should be sanitized before installing the Sediment/Carbon Prefilter and Activated Carbon Post Filter.
•
Use a good quality unscented 5¼% liquid chlorine household bleach.
•
Add one capful of bleach (this is 2 tsp. or 10 ml) to the Sediment/Carbon Filter Housing and temporarily install
the Housing without the Sediment/Carbon Prefilter. Check the Housing O–ring for proper position in its groove,
engage and firmly tighten the Housing hand tight only.
•
Add one capful of bleach to the Activated Carbon Filter Housing. Carefully fill the Housing with tap water and
temporarily install the Housing without the Activated Carbon Post Filter.
•
The Dispensing Faucet should be open, slowly open the Feed Water Saddle Valve.
•
As soon as water begins to drip out of the Dispensing Faucet, close the Faucet.
•
Let the system stand for 15 minutes.
•
At the end of 15 minutes, in the following order, close the Feed Water Saddle Valve, close the Holding Tank
Valve and open the Dispensing Faucet to release the pressure.
•
Remove the Sediment/Carbon Filter Housing and empty. Remove the wrapping and install the Sediment/Carbon
Prefilter. Firmly tighten the Housing hand tight only.
•
Remove the Activated Carbon Filter Housing and empty. Remove the wrapping and install the Activated Carbon
Post Filter. Firmly tighten the Housing hand tight only.
•
Disconnect the yellow product water tubing that runs from the Holding Tank to the Tee (see Fig. 1, page 5). Put
50 drops of bleach (this is ½ tsp. or 3 ml) into the tubing and reconnect it to the Tee.
NOTE: Now is the convenient time to change the In–Line Activated Carbon Post Filter, see page 13.
•
Slowly open the Feed Water Saddle Valve. When water begins dripping out of the Dispensing Faucet, in the
following order, close the Faucet and then open the Holding Tank Valve.
•
Do not open the Faucet for at least 8 hours.
•
Discard the first three full tanks of water produced, they will contain chlorine.
