REVERSE OSMOSIS
6\
WHAT IS NATURAL OSMOSIS AND
REVERSE OSMOSIS?
Natural or direct osmosis is common in nature, found in places like the semi-
permeable membranes which are part of the vast majority of organisms (e.g.
plant roots, our own body organs, cell membranes, etc ...)
When two solutions of different concentrations of salts (TDS -Total dissolved
solids) are separated by a semi permeable membrane, it naturally produces a
flow of water from the less concentrated solution to the higher concentrated
solution. This flow continues until the concentrations on both sides of the
membrane are equal.
To overcome this tendency, and reverse the natural flow of the system, (in
order to obtain a flow of water from a higher salt concentration solution to a
lower salt concentration solution) pressure is applied to the water on the side of
the membrane with the higher concentration. Pure water is collected from the
lower pressure side of the membrane and this process is what is called reverse
osmosis. Today, reverse osmosis is one of the best methods for improving the
characteristics of water by a physical process (without using chemicals).

https://puricomusa.com/guide/

RO MEMBRANE /7
HOW DOES THE MEMBRANE WORK?
Pressure is applied to the water on the inlet side of the semi permeable
membrane, so that part of it (RO water) will flow through the pores of
the membrane, while the rest of the water (water rejected with high salt
concentration) will be diverted back to the supply pitcher to recycle and
optimize performance.
Since the diameter of the pores of the membrane is less than 0.0001 microns,
only water molecules and a small amount of minerals (sodium, potassium,
calcium, magnesium, etc.) will pass through the membrane. Larger molecules
will be “rejected” from passing through the membrane.

OPERATION /9
OPERATION CONDITIONS
t Do not use water above 113°F (45 °C)
t The ambient temperature must be between 40
and 104 °F (4 and 40 °C. )
t Keep the system from extreme temperatures,
like cooking surfaces, direct sunlight, and
extreme environmental conditions.
t Avoid external dripping on the purifier.
CAUTIONS
Do not use with water that is microbiologically unsafe, of unknown quality, or
without adequate disinfection before or after the system. If the water being used
is from a public supply, it will comply with requirements for water to be used for
the ZIP purifier and your ZIP will substantially improve the water quality.
In the event that the water to be treated is not from a public water supply,
or is of unknown origin, in order to ensure proper purification, contact your
distributor to advise you on the most appropriate physical, chemical and
bacteriological water treatment to use with your ZIP system.
t Unplug the unit before repair, inspection or filter replacement.
EFFECT OF TDS CONCENTRATION
IN THE INLET WATER
Production rate will vary depending on the TDS content (Total Dissolved Solids)
and temperature of water to be treated. Water with a lower temperature and
higher TDS will be filtered slower than water which is warmer or of a lower TDS.
t It is recommended to use water with a maximum hardness of 25 grains in
order to obtain optimum performance.
t If the inlet water is of hardness greater than 25 grains, or contains high
concentrations of iron or manganese, or hyper chlorination, there may be a
reduction in membrane life and performance of certain components of the purifier.
ZIP is designed for TDS up to 800 ppm. For TDS above 800 ppm, consult
your dealer. (If the water being used is from a public supply, it will comply with
requirements for water to be used for the ZIP purifier.)

STARTUP
10 \
STARTUP AND OPERATING
1. Remove purifier and contents from box and place on a convenient counter
top or table within three feet (1 meter) of an electrical outlet. (fig. 1)
2. Equipment must be operated on a level surface and not inclined. (fig. 2)
3. Plug the transformer wire into the power socket on the back of the ZIP. Plug
the electric cord into a wall socket. (fig. 3) (The Push Button Control LED will
glow blue)
4. Remove the supply pitcher from its base by pulling out on the front handle.
(fig. 4) (The LED will flash yellow)
5. Place the pitcher under a faucet and fill to the “Max” level marked on the
front of the pitcher. (fig. 5)
3.

STARTUP
/ 11
8. To dispense Purified water, either push in or pull
out on the dispenser handle. When pulled out,
the handle will stay in the open position. (fig. 8)
6. Replace the supply pitcher to the base of the
ZIP, being sure the pitcher is securely seated
into the base. (The Push Button Control should
glow steady blue.)
7. Press the control button once. (fig. 7)
The purifier will draw water from the supply pitcher and direct purified water
to the Pure Water Tank.
A full course of treatment produces approximately 1/2 gallon (2 liters) of pure
water, stored in the upper reservoir. Unfiltered water is directed back to the
supply pitcher for recycling, allowing optimum performance.

PUSH BUTTON CONTROL

PUSH BUTTON CONTROL - USER INTERFACE
ZIP Purifier has a blue, yellow and red color coded LED electronic control
which integrates a timer, and security functions to efficiently manage the
filtering cycle and indicate any malfunctions detected.

TREATMENT CYCLE / 13
TREATMENT CYCLE TIME
The time required to complete one cycle will vary according to water quality,
water temperature and how long the filters have been used. The filtering
process will turn off automatically once the cycle is completed.
Gradually as the filters and membrane become used, the filtering cycle time
will become longer. Usually the filtering process will complete before reaching
a preset 20 minute time limit. If the cycle does not complete in one 20 minute
cycle, this indicates that the filters should be changed.
Filtration completed less than
20 minutes
Filtration completed more than
20 minutes
Normal condition Filters should be changed

WATER SUPPLY
14 \
CHANGING WATER IN SUPPLY PITCHER.
After completing a filter cycle, completely empty the supply pitcher, and refill
with fresh water before starting another cycle. The water remaining in the
supply pitcher after a filtration cycle has a higher concentration of TDS, so
starting a new cycle, by adding fresh water to this remaining concentrate water
will lower system performance and can damage the RO membrane and filters.
FILTER INITIALIZATION
t When the purifier is being used for the first time, the filters should be rinsed
by running the purifier for two cycles, and discarding the water. Water
from the first cycle may contain fine carbon sediment form the post filter
which may give the water a slight gray color. This carbon is food grade and
healthy, and will not affect the quality of the water. After filtering two cycles,
the pure water reservoir may be removed from the purifier and rinsed with
tap water. (See page 15)
t With filters rinsed, the purifier may now be used for pure water filtration.

CLEANING / 15
Notice:
t Water should not be stored in the purifier for extended periods of time
exceeding one week.
t If you plan to not use the purifier for more than one week, completely empty
the water supply pitcher and pure water reservoir, and disconnect the power
supply. When you return, filter two cycles of water to rinse the system.
t If the purifier has not been used for more than a month, remove and wash
with soap and water both the supply pitcher and pure water reservoir. Rinse
the reservoirs and filter two cycles of water to rinse the system.
CLEANING PURE WATER RESERVOUR
1. Remove top cover.
2. Slide the front cover panel up and remove.
3. Turn the pure water supply tube so it is pointing up.
4. Slide the pure water reservoir forward to remove.
5. Remove supply pitcher.
6. Wash both reservoirs with a soft cloth and soap and water.

RO MEMBRANE REPLACEMENT / 19
RO MEMBRANE REPLACEMENT
How to tell if the RO membrane needs replacement:
The condition of the membrane is assessed by testing the percent TDS (Total
Dissolved Solids) rejection:
Using a TDS meter, compare the TDS of the inlet water to the pure RO water,
and obtain the percentage of TDS rejection.
Your supplier can help you to check your water quality, or you can purchase a
TDS tester to test by yourself.
% rejection rate = TDS of inlet water – TDS of pure water
TDS of inlet water
Example:
Inlet water TDS = 300ppm; Pure water TDS = 18ppm*
300 – 18
300
If rejection goes below 70% the membrane life has come to an end.
* After the RO membrane, the filtered water passes through the post filter which
adds minerals to the water, raising the TDS by about 10 -20 PPM. So the TDS
after the post filter will be higher than immediately after the RO membrane. As
long as the rejection rate calculated after the postfilter (final product water) is
above 70%, the RO membrane is still okay.
90 - 95% > Maximum Quality
70 - 80% > Low Quality
80 - 90% > Medium Quality
x 100
x 100 = 96% rejection rate
