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. (Refer to Figure 2A, page
9.) 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 and Activated Carbon Post
Filters to be rinsed out. This is normal for
the first tank of water or after the Activated
Carbon Post Filters are 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 Filters. After this water is rinsed to drain,
the removal rate should stabilize at a value of
greater than 75%. The Water Quality Monitor
was designed to measure water quality when
the R.O. system is making water. In order to
assure you are getting an accurate reading,
empty the holding tank, wait 15 minutes until
the system begins making water, and then
test the TDS with the monitor.
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 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
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 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 13, 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 by lifting the handle. 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.
