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 5-micron PP lter (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 granular activated carbon lter:
The lter effectively absorbs chlorine, mould, disinfection by-products,
odors, discolorations and other materials suspended in the water.
• The third stage is a 1-micron PP lter (Sediment)
This lter further removes small particles within in the water, suspended
solids, colloids, etc.
• The fourth stage is the RO membrane:
The RO membrane with a pore size of 0.0001 micron (0.1 nm), it can
effectively remove bacteria, viruses, heavy metals, pesticide residue, and
other harmful substances. Produced water is fresh, pure and suitable
for direct use.
• The fth-stage is a post-activated carbon lter:
This lter regulates the taste of water and keeps the water fresh .
Note: the parameters above may change due to product improvements, but the product name plate shall remain the same. TDS refers to inuent total dissolved solids.
Note:
0.1 MPa = 1.02 Kg/cm2 = 14.5Psi
1 Psi = 0.07 Kg/cm2
1 Gallon = 3.785 Liters

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.
• 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.

ENG 11
Instructions for Proper Installation
• Method of installing the inlet water metal hose and 3-way inlet
waterjoint:
(If the metal hose diameter is 9 mm the 3 - way inlet water joint must be
purchased separately) First, close the inlet water valve. Screw off
the metal hose. Remove the 3-way inlet water joint from the water
purier
accessories box, screw one end of the inlet water 3-way joint onto the
inlet
water valve outlet. One end of the unscrewed metal hose should be
screwed
into the 3-way inlet water joint using the screw nut (See Diagram 4)
• Method of installing the 3-way inlet water joint and inlet water ball valve:
Take out the inlet water ball valve from the water purier accessories
box, wrap one end of the external threads on the ball valve with
appropriate
teon tape (See Diagram 5). If you have silica gel, spread a little over
the thread and then screw the ball valve into the corresponding hole
of the 3-way inlet water joint (See Diagram 5). Take out the Ø 9mm
water pipe from the accessories box. Using a pair of scissors, cut
a suitable length of pipe and connect one end of the pipe to
the inlet water ball valve (See Diagram 6). Finally screw the nut in place.
• Installation of the osmosis faucet:
Drill a φ14mm hole in an appropriate position on the counter where
the faucet is to be installed. Then take out the faucet from the water
purier accessory box. Begin the installation of the faucet. First put
the stainless steel neck on the faucet main body (See Diagram 7), then
lower the main part of the faucet into the hole you have drilled. Put
the spacer on the lower part of the faucet and screw the xed nut on
to the bottom end of the faucet in order to x the faucet to the counter.
Finally, attach the appropriate length of 6mm pipe into the water inlet
connection. Attach the 6mm pipe stopper into one end and place it
on the 6mm nut. Screw it on the bottom of the faucet (see Diagram 8).
If you want to x the faucet on a wall, please use the faucet hanging
piece (when installing be sure to tighten the joints to prevent leakage).
• Installation of the waste water pipe:
Drill a small hole into the sink drain pipe using a φ 6mm drill. Take
a suitable length of the 6mm water pipe and lay one end just inside
the drilled hole (See Diagram 8), put some silica gel where the 6mm
pipe and the drain pipe connect to prevent leakage. Use a cable tie to x
the waste water pipe to the drain pipe (for large ow water puriers;
you will need to insert a waste water clip into the drilled drain pipe hole)

• Membrane Installation Warnings:
•The package of the reverse osmosis membrane contains a small amount
of protective solution in order to prevent microbiological contamination
of membrane components during storage and transportation.
• You should pay attention to the direction of the RO membrane during
installation.
• 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 pipes
- Before installing the pipes, make sure that the surface of the pipes is
smooth. Cut the pipe on the front-end perpendicular with the length
of the tube with scissors and then make the cut section round before
inserting inside (see diagram 10 for the correct way of cutting);
If the pipe is not round, but still elliptical and then is inserted inside,
it will damage the O-ring and cause water leakage.
- While installing the water pipe, it will get stuck at the rst bayonet
before the pipe is completely seized by the connectors. Push it hard
until the pipe reaches the end. If the pipe cannot be inserted into the
deepest end, it probably breaks away when transferring the pressure.
(see diagram 11)
- When removing the water pipe, push in the jack catch rst and then
pull out the pipe (see diagram 12).
- After the water pipes have been connected, safety clips should be
installed on the quick ttings to avoid the ttings to break away.
(see diagram 13)

ENG 13
• Drain Hole
A small hole is located at the bottom of the appliance. This hole is tapped
with a rubber cap. When there is water leakage inside the cabinet, this
hole is used to drain the water.
Follow below steps in case of a water leakage inside the cabinet:
• Cut inlet water line and power to the unit.
• Take the unit inside sink.
• Remove the rubber cap located just at the middle of unit base.
• Wait until the water inside the cabinet is evacuated.
• After all water is evacuated, place the rubber cap on the drain hole.
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.

Then, follow these steps to adjust the purier:
• Open the tap water inlet valve and the water purier inlet water ball
valve and plug the purier in the power outlet (See Diagram 14). Close
the storage tank ball valve, then automatically start a 120 second
ushing process, water will start to drain through the discharge outlet.
• Wait for the water purier to operate stably (for about 5-10 minutes).
Check each connection to make sure they are secure. Check to see if
there is any leakage from the membrane shell, lters, etc.
•Close the pure water osmosis faucet and storage tank ball valve. Wait
approximately 30 seconds. Check to see whether or not the water
purier waste water and high pressure pump have stopped working.
• Open the osmosis faucet. Check to see if the water is owing through
the faucet. If not, check to see whether the tap water pressure is too low
or whether or not the high pressure switch can be reset automatically.
•Wait until the machine is operating properly, then close the inlet water
ball valve. After a short period of time, check to see if the machine stops
working, if it does not stop working, check to see whether or not
the low-pressure switch can be reset.
•Perform a second check to make sure everything is ok. Now your water
purier is ready for use.

•The major components of this product are manufactured using plastic.
When using the water purier, always observe the integrity
of the equipment in order to ensure safe operation.
•The package of the reverse osmosis membrane contains a small amount
of protective solution in order to prevent microbiological contamination
of membrane components during storage and transportation. The
PAC 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 use the storage tank it is recommended that you discard
the rst tank of water; otherwise it may result in abnormal tasting pure
water.
• 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 the unit is not operated for long periods of time, occurance of
microbiological contamination is possible.
To prevent any microbiological contamination, it is recommended to
operate the unit at least twice a week. Otherwise, the water can have a
smell.
• When any of the following situations occur, immediately disconnect
the water purier water source (close the inlet water ball valve) and/or
the power source and carry out repairs.
- If the water purier pipes or related components are leaking.
- If the water purier and/or components stop working.
- If any components leak electricity.
- If there are any other anomalies or failures.

ENG 15
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 users 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 them of 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:
Important Note:
Water quality has a great inuence on the life-cycle of the lters. The
lifespan of the RO membrane is affected by many factors.
The table above represents the lifespan of lters under standard
conditions. In actual usage, due to the fact that water quality may be
different, the lifespan of the lters may exceed or may be lower than the
abovementioned estimates.
The above data is provided for reference only. Under normal circumstances,
if you witness the following indications, you should consider replacing your
lters:
• Poor water quality, taste declines, TDS value of water rises TDS value of
water;
• Water ow is signicantly reduced. Check to see if the lter or
membrane is blocked (determine that it was not caused by a temperature
drop);
• If the lter’s outer surface is covered in mud or the lter has signicantly
changed color;
• If serious lter clogging leads to no pure water ow from the unit.

and inlet water temperature of 25C . If net pressure is less than 0.5MPa
or if the inlet water temperature is less than 25C, 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 2.5G.
However this gure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is app. 2G
• 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.
Filter Replacement Methods
• Replacing the quick change lters
First close the inlet water ball valve. Pull out the water pipes on the both
ends of the old lter cartridge. (see diagram 10, 11 for the usage
method of quick ttings). Throw away the old lter cartridges. Then
make the connection of the new inline lters on the both ends.
Finally put the lter cartridge into the big clip. Pay close attention to
the arrow on the lter cartridge and connect the lter cartridge with
the water pipes following the arrow direction, the left side is for outlet
water and the right side for inlet water.(see diagram 15).
