2. R.O. systems produce drinking water at
relatively slow rates; it can take up to 5 hours or
more to fill the Holding Tank. Normal operation
is to let the Holding Tank fill with water and then
draw water as is needed. When the pressure in
the Holding Tank falls to a given pressure (as
the water is being used) the Automatic Shutoff
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 faucet for at least 10 seconds prior to
using water. This is especially important if the
system 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 water 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 Sediment/Carbon Prefilter and the
Activated Carbon Post Filter.
B. Changing Filters
THIS R.O. 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 R.O. Membrane) is every 6 to 12 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
Sec. IV, F.1–3 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.
1. Close the Feed Water Saddle Valve by turning
fully clockwise and open the Dispensing
Faucet. Allow the Holding Tank to empty.
2. Loosen and remove the Sediment/Carbon
Prefilter and the Activated Carbon Post 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 Prefilter 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 Post 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 Prefilter
Housing and empty. Remove the wrapping
and install the Sediment/Carbon Prefilter.
Firmly tighten the Housing hand tight only.
• Remove the Activated Carbon Post 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
Manifold (see Fig. 1, page 5). Put 50 drops of
bleach (this is ½ tsp. or 3 ml) into the tubing
and reconnect it.
• 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.
• When the Faucet is first opened, expect air
and carbon fines (very fine black powder),
from the new Activated Carbon Post Filter to
be rinsed out. This is normal for the first tank
of water.
