Collection Instructions

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 are de-
pending on the model you bought, between 1 and 6.

For RO-Systems without pump:

If you use pressure tank, input water pressure should be higher than 85 psi.

Operation Principle

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 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 density 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 only
0.0001micron, bacteria and filterable virus can pass the RO membrane only if the bacteria would be
reduced in size 4000 times, and filterable virus would be reduced in size more than 200 times. Conse-
quently, 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 harm-
ful 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 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 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

return

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.

Operational Approach

After the installation

，

please wash the filters of each stage before using the system 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 supply socket

，

then the high pressure pump(H) starts up automatically

，

the waste water outlet begins to drain

，

filters

of each stage are being washed automatically.

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 you use this sys-
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 you use the system 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 you use the system for the first time, TDS test data may be a bit high

，

please con-

tinue washing until the TDS test data becomes normal.

C) When you use the system 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 system begin to produce purified water automatically

．

Usually,

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 system stops working automati-

cally. Turn on the goose-neck faucet (Q) to use the purified water.

Maintenance

It is highly recommended to replace filters periodically to keep the high quality of water. This helps to
take full advantage of filters and guarantee the standard of water quality. If a user takes care of the fil-
ters and replaces them periodically, the water purifier system could have a longer lifetime. The period
of Filter-replacement depends on the quality of the raw water, the impurity quantity of the raw water.
Based on empirical statistics a family of four persons usually consumes l0L (10kgs) purified water
each day.

Version 3.2016

RO membrane pressure washing

：

When RO membrane purifies the water, there is impurity and bacteria left on the surface of the water,
which may affect the quality and volume of the purified water

．

Thus the RO membrane must be

cleaned periodically

．

In our system, the RO system will flush the RO membrane manually by turning on

the flush valve (L1) for 2-3 minutes once a week.

Notice

：

In order to make you system work efficiently, please use the specified filters, provided by the

same vendor of the purification system.

Warning

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 successfully.
Clean the remaining contaminants and sediment in the unit.
Check if the unit works normally and without water leakage.

Don’t take apart the parts of system. Any wrong operation may lead to water leakage and system
failure/damage.

Don't apply the system to purify hot water.

Don’t place air valve discharged on the pressure tank.

To ensure the quality of purified water, please replace the first and the second filters in a period of
no longer than 10 months.

Please check the power supply and make sure it is a suitable voltage.

Keep the RO unit away from sunshine.

When the system is not used for a long period, please turn off the power and shut off the ball
valve.

Follow the initial operation before reusing the system after longtime standing idle.

Load move and install it carefully.

Version 3.2016

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 supply 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 may cause the pump to be overloaded

RO system does not operate.



Check if power supply 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

RO system can not operate automatically



Check if there is any wrong operation.



Check if the high and low pressure valve is normal.

Pump head leakage:



Check if post in-line carbon filter (T33) or PP cartridges are blocked this may cause the
leaking. Sometime the leakage may be caused by 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 by 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 by improving the relevant components.



Pump is operating normally

，

but can not generate purified water:

The cause may 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.

No purified water coming out while tank is full of water

：



The cause may 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.

The wastewater keeps on discharging when the tap of RO system is closed.



Check if flush valve is operating normally; otherwise, replace it.



The input water valve was damaged.

RO system could not be completely stopped or restart operating quickly 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.

The volume of purified water is too little

：



Check if the filters are not to dirty and exceeded the filter's service life

．

If it is caused by

the RO membrane that is to dirty or not be flushed regularly. Please replace it.



Check if temperature of water is to cold.

The water delivering pressure is not as good as that of the new system. Please replace the pump
