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%. The optional Water Quality
Monitor measures the TDS reduction and gives
an indication of proper performance.
2. R.O. systems produce drinking water at rela-
tively slow rates, it can take up to 6 hours or
more to fill the Holding Tank. Normal operation
is to let the Holding Tank fill with water and
then draw water as needed. When the pres-
sure in the Holding Tank falls to a given pres-
sure (as the water is being used) the Automatic
Shutoff Valve (ASO Valve) will start water pro-
duction and the system will refill the Holding
Tank. When the Holding Tank is full and no
water is being used, the ASO Valve will auto-
matically 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 turn
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 bet-
ter 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 REGU-
LAR INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED FILTERS.
All individuals should take adequate precautions
when changing the filters, including wearing protec-
tive gloves, to avoid direct contact with the exhaust-
ed filters.
The recommended interval for changing the
filters (not the R.O. 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 R.O. Membrane is to be replaced,
see Sec. IV, F.1–3, page 9 for the proper proce-
dure.
Use a drip pan to catch any water that may spill
when the Filter Housings are removed. Refer to
Fig. 1, page 1 for component location.
1. Close the Feed Water Saddle Valve by turning
fully clockwise and open the Dispensing Faucet
by lifting the handle. Allow the Holding Tank to
empty.
2. 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 5 % liquid chlo-
rine 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, slow-
ly 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.
