This manual describes the Usage of all our RO systems.
Please note that some parts of this manual are intended for certain systems. Usually the arrangement
of the filter stages is always the same. The number of filter stages depend on the model that you have
bought, between 1 and 6.
For RO-Systems without pump: If you use a pressure tank, the input water pressure should be higher
than 85<psi.

The RO system adopts U.S. high-tech reverse osmosis technology. This automatic reverse osmosis
system is composed of five filtration stages: First, the raw water is filtered by three pre positive cart-
ridges.
The first stage: The PPF cartridge removes suspended substance and other substances up to 5 mi-
cron in raw water.
The second stage: Granular activated carbon cartridge.
The third stage: High density activated carbon cartridge to remove odor, chlorine and its outgrowth in
raw water.
fter above three stages of filtration, the filtered water is pushed into the fourth stage: the reverse os-
mosis (RO) membrane with a high-pressure pump. Since the aperture of the RO membrane is only
0.0001<µ, bacteria and filterable virus can pass the RO membrane only if the bacteria would be re-
duced in size 4000 times, and filterable virus would be reduced in size more than 200 times. Con-
sequently, any super fine impurities, harmful soluble solid, bacteria and virus in water is blocked by the
high density RO membrane. The RO membrane can also filter other impurities and contamination from
the filtered water. The harmful substance is automatically removed by means of a waste water outlet.
The water filtered through the RO membrane enters a pressure tank for storage.
When the user turns on the goose-neck water-tap, the purified water will go through the fifth stage:
post positive bacteriostatic activated carbon filtration and
into the sixth stage: UV light to kill e.<g. bacteria, virus, or mineral balls to re-introduce minerals into
the water.
The system controls the water purification process automatically. When the pressure of raw water is to
low or the water storage tank is full, the system will stop the purification machine automatically; when
the water pressure returns to the normal level, the purification machine will turn on automatically.
The water purified by the RO system is pure drinking water without bacteria and impurities, rich in oxy-
gen, tasty and excellent for your health.
