Functions of the Main Components
The standard conguration of the water purier that utilizes the current,
most advanced international RO technology is as follows:
The rst stage is a 10" 5-micron PP Filter (Sediment):
The pores on the aperture within the PP lter is 5 microns wide so it
can effectively lter rust, sand, other larger particles and solid impurities
suspended in the water.
The second stage is a 10" Granular Activated Carbon Filter:
The lter effectively absorbs chlorine, mould, disinfection by-products,
odors, discolorations and other materials suspended in the water.
The third stage is a 10" Block Carbon Filter:
This lter further removes small particles within in the water, suspended
solids, colloids, etc.
The Fourth stage is the RO membrane:
The membrane has an aperture of 0.0001 micron (0.1 nm) that reduces
bacteria by 4,000 fold, reduces viruses by over 200 fold, so you can
effectively remove bacteria, viruses, heavy metals, pesticide residue,
and other harmful substances contained in your water supply.
The fth-stage is a post-activated carbon lter:
This lter regulates the taste of water and keeps the water fresh.

Functions of Accessories
Storage Tank: Used to store water ltered by the water purier.
High Pressure Pump: Boosts pressure to create a stable environment
for the RO membrane.
Flow Restrictor Device: Controls waste water ow.
Low Pressure Switch: Prevents pump idling. When the inlet water
pressure is less than 0.03 MPa or when the inlet water stops,
the low-pressure switch automatically shuts off the power source
so the machine comes to a halt.
High-Pressure Switch: Prevents pump from overdrive. When the storage
tank is full or has reached the set pressure level, power supply is
automatically cut off to stop the operation of the machine.
Inlet Water Valve: It is used to turn on/off incoming water.
Check Valve: Also known as a one-way valve, controls the direction
of water ow.
Transformer: Converts 220V AC to 24V DC (the machine’s safe
operating voltage).
Shut-Off (4 Way) Valve: It directs the ow of puried and drain water.
It is synchronized with the RO pump action. When the pure water
storage tank is full of water, the RO pump and shut-off valve will
automatically shut down. When shut-off valve shuts down, the puried
and drain water both will be shut down.

• When installing the RO membrane; you should rst make sure that one
end of the membrane has an O-ring;
• During installation, be sure to put the end with the O-ring into the end
of the membrane shell with the pure water connection. If you install
the reverse osmosis membrane correctly, you will only need a little force
to mount it into the membrane shell. If you encounter too much
resistance, please do not force the reverse osmosis membrane into
the membrane shell. Doing so may cause permanent damage to the
membrane shell or membrane components (the membrane
manufacturer does not assume responsibility for returned components
due to damages incurred during installation).
• Damage to the membrane shell and reverse osmosis membrane
components inicted as a result of the abovementioned reasons is not
covered under the water purier’s warranty.
• Do not cut or try to disassemble the replaced membrane. RO membrane
can lter microorganisms and cutting or harming RO membrane may risk
on you and your environments health.
 Installation of the Pre-Filters:
First take the pre-lters out of their packages. Tear off the packaging
of the lters in the order they should be installed: rst is the 5 micron PP
lter; second is the granular activated carbon lter, note that the rubber
pad must be installed on the top of the activated carbon lter; third is
the 10" block carbon (See Diagram 15).

ENG 15
 Installation of the Storage Tank:
First wrap teon tape around the water nozzle (4-5 turns). Use a little bit
of silica gel to prevent water leakage and loose connections. Then,
screw in the water tank ball valve into the water nozzle and nally
connect the water pipe to the storage tank: rst cut a suitable length of
the 6mm tubing, then put a screw nut on each end of the tubing. One
end of the piping should connect to the water purier labeled storage
tank connector, the other end should go in the storage tank ball valve
(See Diagram 16). Finally place the storage tank on the oor.
Installation Notes
When installing the water pipes, you should not install a drain stopper.
Furthermore, the screw nut on the water pipe bottom connector should
have no wire teeth exposed.
If the inlet water pipe is 9mm, you should ensure that the inlet water
pipe and connector have 30-40cm of straight piping to avoid pipe
bursting accidents caused by bending of the pipe.
 If the power cord wiring needs to be longer, extend the cord according
to the wiring requirements and use an 8mm pinched tube to wrap
around the connection. Later, wrap insulating electrical tape
on the outside surface. Do not place the cord on the oor. The cord
should be suspended in the air or should follow a path above ground.
During installation, make sure that there is no electrical wiring or water
pipes embedded inside the walls where you will do the drilling.

of the equipment in order to ensure safe operation.
 The post activated carbon lter may emit activated carbon powder
the rst time it is used. So do not open the water storage tank during
the rst hour when the water purier is put into operation. It is
recommended that the water produced during this period is disposed of.
Otherwise, the taste of the pure water may be unusual.
 When you rst operate the water purier, the pure water TDS value may
be a little high. After operating for some time, the TDS value of the pure
water produced will gradually decrease until it is stable.
 When you are using the water purier, the inlet water ball valve should
be opened and the pure water faucet needs to be turned on. When
you are not using water turn off the water faucet, the high pressure
switch will automatically cut off the water supply.
 When you rst use the storage tank it is recommended that you discard
the rst tank of water; otherwise it may result in abnormal tasting pure
water.
It is recommended that you use the machine at least twice a week
to prevent microbiological contamination caused by the equipment lying
idle for an extended period of time, which in turn might cause odors
in the water.
If you did not use the machine for a longer period (more than one week),
before using puried water, follow the below steps:
- Turn off water inlet
- Cut off electricity
- Empty the water storage tank. Turn on the inlet water and electricity.
The machine will begin reverse osmosis.
If you did not use the machine for long periods (i.e 1-2 months), replace
the lters before using the machine.
 In these “operation warnings”, “operation” refers to the power supply
being connected and/or the inlet water ball valve being open
so the water purier is in an operational state.

Filter Replacement Intervals
 The lter replacement cycles for the various lters used in this purier is
derived from statistical indicators on the estimates of average tap water
usage. If there are considerable discrepancies between the supply
water quality, utilization rates and average indicators, there will be more
obvious differences between the lters actual replacement intervals
and estimated life-cycles and users may experience premature lter
clogging, premature failure, etc. If this occurs, lter replacement
intervals should be based on actual usage conditions. You should also
contact your local after-sales service department immediately to inform
the situation.
 This machine’s estimated lter replacement cycle is based on average
household water consumption and is suitable only for residential use,
do not install this machine in places that require large volumes of water.
If the water volume requirements are large, our company offers
appropriate equipment tailored for commercial applications.
According to economic statistics on municipal tap water, a three person
family on average uses 10L of water a day. According to the water
volume and inlet water quality conditions, approximate ltering
volumes are as follows (the following data is for reference only):

• Replacement of the 1st and 3rd stage lters:
First of all close the inlet water ball valve. Using the lter cartridge
wrench, unscrew the 1st and 3rd stage lter cartridges. Remove the old
lters and take the new lters out of their packaging. Finally place
the lters in the lter cartridges (Note: place the 5 micron PP lter
in the 1st stage lter cartridge, the block carbon in the 3rd stage
lter cartridge), using the lter wrench, tighten the lter cover.
• Replacing the 2nd stage lter:
First of all, close the inlet water ball valve. Using the lter cartridge
wrench, unscrew the 2nd stage lter. Remove the old lter and take
the new lter out of its packaging (note: the rubber pad on the lter
does not need to be taken off). Place the lter inside the lter cartridge
(note: the granular activated carbon lter should be placed with the
rubber pad end directed up towards the lter covers). Finally, use
the wrench to tighten the lter cover.
• For replacement of membrane elements please see
“RO Membrane Installation”
Warnings
• Notes before using replaced lters: After replacing the granular activated
carbon lter (2nd stage), you must rst ush out the machine in order
to avoid the activated carbon powder from the granular activated
carbon lter from owing into the 3rd stage lter or even
the RO membrane, which may result in damage to lter and membrane
components.
If there is dark colored water near the third stage lter, perform the
following steps:
- Turn off the water purier inlet water valve;
- Using the lter cartridge wrench, remove the water purier’s 3rd
stage lter;
- Place a large container near the 3rd lter cartridge cover to collect
the dark colored water;
- Open the inlet water valve, wait until the water is no longer dark;
- Close the inlet water valve, reinsert the 3rd stage lter into the lter
cartridge, and screw it in tight.
Please ush the post-activated carbon lter for 1-2 minutes before using.
• RO membrane water production volume:
The water output volume of the RO membrane component is
inuenced by inlet water pressure and water temperature.
Your equipment’s declared volume of 75GPD is tested under a net
pressure of 0.5MPa and inlet water temperature of 25°C .
If net pressure is less than 0.5MPa or if the inlet water temperature is
less than 25°C, water output volume of the RO membrane component
will be less than 75GPD.
• Storage tank capacity:
The storage tank on your equipment has a stated capacity of 3.6G.
However this gure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is app. 2.5-2.8G.
• Disposal of old lters:
After replacing old lters, they cannot be cleaned and reused; it is
recommended that you dispose of them with solid waste garbage.
