Collection Instructions
This Manual describes the Usage of all our RO.S stems.
Please note that some parts of this manual are intended for certain s stems.
Usuall the arrangement of the filter stages is alwa s the same. The number of filter stages are de-
pending on the model ou bought, between 1 and 6.
For RO-Systems without pump:
If ou use pressure tank, input water pressure should be higher than 85 psi.
Operation Principle
The RO s stem adopts U.S. high-tech reverse osmosis technolog . This automatic reverse osmosis
s stem is composed of five filtration stages．First, The raw water is filtered b three pre positive car-
tridges．
The first stage：PPF cartridge, remove suspended substance and other substances up to 5 micron in
raw water. The second stage：granular activated carbon cartridge;
the third stage：high densit activated carbon cartridge, to remove odor、chlorine and its outgrowth in
raw water．
After 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 onl
0.0001micron, bacteria and filterable virus can pass the RO membrane onl if the bacteria would be
reduced in size 4000 times, and filterable virus would be reduced in size more than 200 times. Conse-
quentl , an super fine impurities, harmful soluble solid, bacteria and virus in water is blocked b the
high densit RO membrane．
The RO membrane can also filter other impurities and contamination from the filtered water. The harm-
ful substance is automaticall removed b 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 faucet,
the purified water will go through the fifth stage: post positive bacteriostatic activated carbon filtration
and into the Sixth stage: UV light to kill bacteria, virus and son on or mineral balls to put minerals
back into the water again.
The s stem controls the water purification process automaticall . When the pressure of raw water is to
low or the water storage tank is full, the s stem will stop the purification machine automaticall ; When
the water pressure returns to the normal level, the purification machine will turn on automaticall .
The water purified b the RO s stem is pure drinking water without bacteria and impurities, rich in ox -
gen, tast and excellent for our health.
The different filter stages:

Operational Approach
After the installation，please wash the filters of each stage before using the s stem for the first time.
The steps is as follows:turn on the ball valve( B) of the faucet tubing, turn off the tank valve(M) of wa-
ter storage tank(N),turn on the goose-neck faucet(Q),
Open the flush valve (L1)).
plug the power cord into power suppl socket，
then the high pressure pump(H) starts up automaticall ，the waste water outlet begins to drain，filters
of each stage are being washed automaticall .
After washing the tank, turn on the tank valve (M) of water storage tank (N) and turn off the goose-
neck faucet (Q), the reverse osmosis filter begins to generate purified water. When ou use this s s-
tem for the first time, let the purified water flow out from the full water storage tank twice, then the puri-
fied water is suitable for drinking.
Notes:
A) When ou use the s stem for the first time, turn on the goose-neck faucet to drain the
water. (There could be a little bit of black water flowing out from faucet ，please continue
washing to drain it)
B) When ou use the s stem for the first time, TDS test data ma be a bit high，please con-
tinue washing until the TDS test data becomes normal.
C) When ou use the s stem for the first time, the purified water is not drinkable until steps
A and B are done. The concentrated waste water used for the making of the purified wa-
ter cannot be used for drinking.
After the installation & adjustment, the s stem begin to produce purified water automaticall ．Usuall ,
turn off the goose-neck faucet(Q)、turn on the tank valve(M) of water storage tank，let the purified water
flow into tank. When the water storage tank is full of purified water，the s stem stops working automati-
call . Turn on the goose-neck faucet (Q) to use the purified water.
Maintenance
It is highl recommended to replace filters periodicall to keep the high qualit of water. This helps to
take full advantage of filters and guarantee the standard of water qualit . If a user takes care of the fil-
ters and replaces them periodicall , the water purifier s stem could have a longer lifetime. The period
of Filter-replacement depends on the qualit of the raw water, the impurit quantit of the raw water.
Based on empirical statistics a famil of four persons usuall consumes l0L (10kgs) purified water
each da .

RO membrane pressure washing：
When RO membrane purifies the water, there is impurit and bacteria left on the surface of the water,
which ma affect the qualit and volume of the purified water．Thus the RO membrane must be
cleaned periodicall ．In our s stem, the RO s stem will flush the RO membrane manuall b turning on
the flush valve (L1) for 2-3 minutes once a week.
Notice：In order to make ou s stem work efficientl , please use the specified filters, provided b the
same vendor of the purification s stem.
Warning
1) Don't drink the water of first two tanks; let it drain or use it for other utilities upon installation. And
test the RO unit for about 2 hours until the above operations is completed successfull .
Clean the remaining contaminants and sediment in the unit.
Check if the unit works normall and without water leakage.
2) Don’t take apart the parts of s stem. An wrong operation ma lead to water leakage and s stem
failure/damage.
3) Don't appl the s stem to purif hot water.
4) Don’t place air valve discharged on the pressure tank.
5) To ensure the qualit of purified water, please replace the first and the second filters in a period of
no longer than 10 months.
6) Please check the power suppl and make sure it is a suitable voltage.
7) Keep the RO unit awa from sunshine.
8) When the s stem is not used for a long period, please turn off the power and shut off the ball
valve.
9) Follow the initial operation before reusing the s stem after longtime standing idle.
Load move and install it carefull .

Trouble Shooting
If the following problems occur, please check as follows:
1) Pump can not work to generate purified water：
Check if the pressure of water suppl is high enough to work. The RO controller box
does not start the pump under low pressure.
Check if either high pressure switch or flush valve works, (stuck)
Check if the fuse on transformer is burned ，if so, then check if post in-line carbon
filter(T33) or PP cartridges is blocked, it ma cause the pump to be overloaded
2) RO s stem does not operate.
Check if power suppl is normal.
Check if the feed water ball valve has been turned on (check if water pressure is nor-
mal).
Check if the water storage tank is full of water
3) RO s stem can not operate automaticall
Check if there is an wrong operation.
Check if the high and low pressure valve is normal.
4) Pump head leakage:
Check if post in-line carbon filter (T33) or PP cartridges are blocked this ma cause the
leaking. Sometime the leakage ma be caused b the increased pressure of the water
in the pump head that cannot be released outward. If so, replace all the carbon car-
tridges and send the pump for repair.
Also either a weakened diaphragm or the blocked scale could cause the leaking.
The water can not flow out due to the blocked RO membrane, which is caused b a
blocked flow restrictor. This cause the pump head to be filled with high pressure water
that can cause a leak. It could be rectified b improving the relevant components.
Pump is operating normall ，but can not generate purified water:
The cause ma be that the RO membrane is blocked or pump is out of pressure. If the
RO membrane is blocked ，please replace the RO membrane. If the cause is that the
pump has no pressure，please check if it is due to either the pump being loaded for to
long a time or the filtering materials is often blocked and the adequate maintenance is
not done，this can caused the pump structure to be weakened. Send pump for repairing.
5) No purified water coming out while tank is full of water ：
The cause ma be the air inside the tank is out. Please recharge the air (7 psi) and
check if the tank has air leakage. If it does, please replace the tank.
If the post in-line carbon filter is blocked. Please replace the filter.
6) The wastewater keeps on discharging when the tap of RO s stem is closed.
Check if flush valve is operating normall ; otherwise, replace it.
The input water valve was damaged.
7) RO s stem could not be completel stopped or restart operating quickl while the tank is full.
High-pressure switch is out of work. Please repair or replace it.
Check if valve is releasing pressure and is not stuck. Please replace it.
8) The volume of purified water is too little：
Check if the filters are not to dirt and exceeded the filter's service life．If it is caused b
the RO membrane that is to dirt or not be flushed regularl . Please replace it.
Check if temperature of water is to cold.
The water delivering pressure is not as good as that of the new s stem. Please replace the pump
