Side Stream R.O. Membrane Technology is a special innovation by
A.O.Smith. Side Stream R.O. Membrane use patented MLSB Screw-type
Technology.
MLSB (multi-leaves single-bag) membrane has vertical inow and
concentrate water direction; longer and narrower inow passage thus
app. 2,8 times higher surface ow rate. Higher ow rate can reinforce the
effect of surface ush, of R.O. membrane, reduce the rate of concentration
polarization, blockage, scale formation, waste water discharge, and
increase the salt rejection rate.
The Side Stream R.O. membrane increases the recovery rate to around
50%, compared to 25% for the regular residential R.O. membrane, and
waste water volume is reduced by 56%.
Combined with MLSB Screw-type Technology, Side Stream R.O. Membrane
creates the world’s highest utilization rate for residential membranes,
reaching 85-90% compared to only 70% for traditional membranes.
With patented full ush function, it completely solves the traditional water
purier problem of having no way for the concentrate water to ush out
of the membrane when the tank is full, leading to membrane scale and
pollution problems. The optimal ushing design reduces ushing discharge
by 50% and extends the service life of the membrane by 1,5 times.
Advantages
• Less Waste Water: It can reduce 56% waste water, energy saving,
en vironmental protection, enjoy low carbon living;
• More Pure Water: It can increase 66% pure water, more efcient and
highest utilization;
• High Salt Rejection: Its salt rejection can be more than 95%, which is the
top level of residential membrane;
• Long Life: By less concentration polarization, it has a low risk
contamination and long life span app. ;
• Reliable Structure: It has water hammer and attack protection, mistake-
proof design to prevent wrong installation;
• Better Sealing: Two o-ring design, completely leak tight, insure pure
water quality;
• Compact Size: 10% smaller, more compact, lighter design.

• During the rst operation of the unit, before activating RO membrane,
pre-lters should be ushed. Follow the below steps to ush the
pre-lters:
- Turn off the inlet water solenoid valve.
- Take out third stage RO membrane housing.
- Place a storage cup to next to the Second Stage Carbon Block housing to
drain the dark color water coming from the Second Stage Filter.
- Turn on the inlet water solenoid valve and wait until the color of the
water returns to normal.
- Turn off the inlet water solenoid valve and reassemble third stage RO
membrane housing.
- Before using Fourth Stage PAC, ush the cartridge for 1-2 minutes also.
•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.
• 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.
