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 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 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 prefilter and post
filters.
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 R.O. 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 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
Tee (see Fig. 1). Put 50 drops of bleach
(this is ½ tsp. or 3 ml) into the tubing and
reconnect it to the Tee.
