SECTION V.
OPERATION & MAINTENANCE
A. Normal Operation
1)
It is normal for the Total Dissolved Solids
(T.D.S.) of the water to be elevated 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
greater than 75%. Water pressure affects
the production rate and quality.
2) R.O. systems produce drinking water at
relatively slow rates; it can take up to 8
hours or more to fill the storage tank.
Normal operation is to let the storage tank
fill with water and then draw water as is
needed. When the pressure in the storage
tank falls to a given pressure (as the water
is being used) the automatic shut-off valve
(A.S.O. valve) will start water production
and the system will refill the storage tank.
When the storage tank is full and no water
is being used, the A.S.O. 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.
After periods of non-use, such as a 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 re-sanitize the system and to change
the activated carbon and sediment filters.
B. Changing Filter & Sanitizing the system
NOTE: THIS R.O. SYSTEM CONTAINS FILTERS
WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED FILTERS.
Please see Page 3 for the recommended interval
for changing the filters. Local conditions may
dictate more frequent changes.
Use a drip pan to catch any water that may spill
when the filter housings are removed:
1) Close plastic supply valve located on the
inlet line of the system.
2) Close the valve on the inlet of the storage
tank.
3) Open the faucet and wait for the flow to
stop.
4) The pre-membrane cartridges can be
hinged out away from the wall. Rotate the
cartridge 1/4 turn counter clockwise and pull
down. The cartridges can be disposed.
5) Push the new filter into the head and rotate
it clockwise ¼ turn.
6) Wipe up any spilled water.
7) To change the in-line post filter refer to the
section dealing with quick connect fittings.
C. Quick Connect Fittings
Your new reverse osmosis drinking water appliance
is outfitted with new generation of user-friendly
quick connect push-in fittings. Proper use of the
fittings is shown in the diagrams.
It is important that the tubing selected for use with
these connectors be of high quality exact size and
roundness, and with no surface nicks or scratches.
If it is necessary to cut the tubing, use a plastic
tubing cutter or sharp razor knife. Make a clean,
square cut.
An optional blue locking clip is installed in certain
fittings to provide extra security. Remove this clip
first before trying to remove tubing by sliding away
from fitting.
Should a leak occur at a fitting, the cause is usually
defective tubing. See next page for instructions on
fixing a leak from a quick connect fitting.
