• Faucet display function:
While the unit power on, open the faucet, the logo “AO SMITH” and
symbol “ ” will be lighted up,the logo shows in white, and symbols color
depends on the service life of filters. During the usage interval, while the
symbol shows in orange or red, please check the unit display and
notice which stage filter, then contact the authorized professionals to
remind and preparation for the maintenance. While close the faucet, both
logo and symbol are also lighted off (See Diagram 15).

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 inflow and
concentrate water direction; longer and narrower inflow passage thus
app. 2,8 times higher surface flow rate. Higher flow rate can reinforce the
effect of surface flush, 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 flush function, it completely solves the traditional water
purifier problem of having no way for the concentrate water to flush out
of the membrane when the tank is full, leading to membrane scale and
pollution problems. The optimal flushing design reduces flushing 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 efficient 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.
