2. Installing the R.O. Membrane:
•Remove the R.O. Membrane Housing, (the
closest of the three to the In-Out ports), and
empty.
•Insert the Membrane up into the manifold.
(The O–rings should be up toward the
manifold.) Check the Housing O–ring for
proper position in its groove, engage and
firmly tighten the Housing hand tight only.
3. Rinsing the system:
•Slowly open the Feed Water Saddle Valve
fully counter clockwise.
•The Holding Tank Valve should be open.
•Check the Air Gap Window on the
Dispensing Faucet to be sure that the drain
water is flowing. The R.O. System is now
making water.
•Do not open the Faucet for at least 8 hours.
•Do not use the first three full tanks of water.
CAUTION: The R.O. Membrane is shipped
with a preservative in it. To ensure proper
rinsing of the R.O. Membrane it is important
to wait at least 8 hours before emptying
each tank.
When the Faucet is first opened, expect air
and carbon fines (very fine black powder)
from the In–Line Activated Carbon Post
Filter to be rinsed out. This is normal for
the first tank of water or after the Activated
Carbon Post Filter is changed.
SECTION V. OPERATION & MAINTENANCE
A. Normal Operation
1. It is normal for the Total Dissolved Solids
(TDS) of the water to be higher than normal
during the first 5 gallons of operation; this is
due to the sanitizing solution and the new
Post Filter. After this water is rinsed to drain,
the removal rate should stabilize at a value of
greater than 75%.
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 Prefilter
and the Activated Carbon Prefilter 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.
