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 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 .
Note: This machine also has an optional conguration
which is as follows:
Pretreatment Filter: KDF two stage lter, KDF three stage lter, sintered
activated carbon lter Post-lter: Alkaline lter, infrared mineralization
activated carbon lter, alkaline sterilization lter, sterilizing lter.
Post-lter: Alkaline lter, infrared mineralization & activated carbon lter,
post alkaline sterilization resin lter, post sterilization resin lter

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.
• Low Voltage Switch: Prevents pump idling. When the inlet water
pressure is less than 0.03 MPa or when the inlet water stops,
the low-voltage switch automatically shuts off the power source
so the machine comes to a halt.
• High-Voltage Switch: Prevents pump from overdrive. When the pressure
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 Solenoid Valve: Connects or cuts off incoming water.
Operating pressure range is less than ≤0.6MPa.
• Check Valve: Also known as a one-way valve, controls the direction
of water ow.
• Auto Flush Solenoid Valve: Automatically ushes the reverse osmosis
membrane.
• Computer Control Box:Converts 220V AC to 24V DC (the machine’s
safe operating voltage).
Water Purier Features
• Low Noise: This machine’s imported parts offer low noise,
few vibrations, long service life, operational quality and reliability;
• Automatic Control System: The system controls the whole water
production process, such as stopping automatically when there is no
inlet water or when the tank is full;
• Auto Flush Function: The system can automatically control the water
auto ush process for the RO membrane to ensure more reliable
and safe operation.

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 osmosis 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)

-Installation of the regular RO Membrane (Model Lotus 75TC):
First take the water purier out of its package. Open the water purier’s
outer cover. Unscrew the membrane shell cover inlet water connection
and take out the inlet water pipe. Then use the membrane shell wrench
to unscrew the membrane shell cover. Take the RO membrane out from
its package. Place the end of the membrane with the O-ring into
the reverse osmosis membrane shell (See Diagram 9) and push it in.
Finally, screw the membrane shell cover back on and use the membrane
shell wrench to tighten the membrane shell cover. Connect the inlet water
pipe into the inlet water connector on the membrane shell and screw in
the nut. Place the membrane shell card into the large single clip available
and attach the water purier cover back on.
Warning Concerning Lotus 75TC:
• 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 installing, 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.
- Installation of the side-stream RO Membrane (Model Lotus 75SS):
Unscrew the membrane shell cover. Take the inlet water pipe out from
the membrane shell cover (see diagram 12).Then, using the lter wrench,
open the membrane shell cover. Remove the membrane from
its packaging. Then put the end with 4 O-rings into the RO membrane
shell (see diagram 10). Finally, screw the membrane shell cover back on
and use the membrane shell wrench to tighten the membrane shell cover.
Connect the inlet water pipe into the inlet water connector on
the membrane shell and screw in the nut. Then place the membrane shell
card into the large single clip available and attach the water purier cover
back on.
Warning Concerning Model Lotus 75SS:
• When installing the RO membrane; you should rst make sure that one
end of the membrane has an O-ring;
• During installing, be sure to put the end with the O-ring into the end

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.
•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 11 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 12)
- When removing the water pipe, push in the jack catch rst and then
pull out the pipe (see diagram 13).
- 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 14)
Installation Notes
• If the power cord wiring needs to be longer, extend the cord
according to the wiring requirements and use an φ8mm 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.

•In these “operation methods”, “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.
•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 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 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.
Operation Methods
Flushing the RO Membrane
As water passes through the RO membrane, impurities and bacteria are
retained on the membrane surface, so you should regularly ush
the machine to ensure that the RO membrane performance is optimized.
• Flushing method: Automatic ushing.
• Flushing step: The membrane will be automatically ushed for
15 seconds each time the water purier is turned on.
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 (the following data is for reference only):

Warning: It is recommended that lter replacement is carried out by qualied
after-sales staff. 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.
Filter Replacement Methods
• Replacing the in-line lters (Option 1)
First close the inlet water ball valve and unplug the power supply. Open
the front cover of the machine. Unscrew the nuts on both sides of the
old lter, and pull out the water pipe. Take out the old lter and remove
the 4044 quick connectors on both ends. Wrap each of the connector
with Teon tap (If you have silica gel, it’s better to have a little on), then
mount onto the both ends of the new lter. Finally assemble the water
pipe back and place the lter back onto the single clip. Pay attention
to the arrow direction on the lter, and connect pipes according
to arrow indicating (left-water inlet, right-water outlet). (see diagram 17)
This 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 water purier.
• Replacing the quick change lters (Option 2)
First close the inlet water ball valve. Pull out the water pipes on the both
ends of the old lter cartridge. (see diagram 11, 12 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 18).

Notes
• 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 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 3.1G.
However this gure is its theoretical capacity and its actual storage
capacity is about 70%-80% of the stated value, which is 2.0-2.5G.
• 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.
Warnings:
• 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.
• When you go out or do not use the machine, disconnect the water
purier's water source (close the inlet water ball valve) and/or power
source.
• If the water purier parts are damaged, it is recommended that the water
purier be entrusted to the manufacturer or distributor, service center,
or specialized technical personnel for replacement to prevent loss caused
by improperly performed maintenance, the manufacturer assumes
no liability for losses incurred as a result of operation or use that does
not conform with the instructions and reminders specied herein.
