DANGER
CAUTION
WARNING

Puritee RO water purifier uses one of the latest technology system that is used in water
purification process. Puritee RO water purifier works under the principle of RO (Reverse
Osmosis) technology which is found to be one of the most effective process in the
world. In this process water under pressure is passed through a semi-permeable
membrane. Purified water is collected for drinking in a storage tank and impurities in the
water are flushed to the drain.
Puritee RO water purifier has 5 stages of purification system, wherein the water is passed
through the various stages & progressively filtered to get purified water which is stored
in the inbuilt storage tank.
 Stage 1 – Pre-PP (Poly propylene) filter
The Pre-PP filter is used to remove physical contaminants such as dirt, dust, soil
particles, turbidity present in the water. This improves the life of the Advanced PP
filter.
 Stage 2 – Advanced PP (Poly propylene) filter
The Advanced PP filter is used to remove fine and coarse physical contaminants
present in the water. This improves life of the CB filter and ensures efficient working
of RO membrane.
Why water purification is important?
Water purification, today is essential due to the presence of vivid and harmful
contaminants present in the water supply. Rapid urbanisation and speedy industrial
growth have led to significant pollutants and contaminants being found in the water
supply. This is a list of some of the harmful contaminants found today in the water
supply which if consumed in excess can be detrimental to human health.
• TDS (Total Dissolved Solids)
• VOC (Volatile Organic Compounds)
• Heavy metals like Iron, Mercury, Arsenic, Copper, Lead etc., Pesticides,
Imbalanced pH.
• Micro organisms such as pathogenic bacteria, virus, protozoa and cysts
Puritee RO water purifier removes excessive TDS (Total Dissolved Solids) like Calcium,
Magnesium, Sodium, Bicarbonates, Chlorides and Sulphates in water by 90%. This
restores the natural taste of water and removes bacteria and viruses. Puritee RO water
purifier also reduces heavy metals like Arsenic, Fluoride and Lead. It balances the pH
value and it also removes bacteria and viruses. By this, it ensures you safe and great
tasting water.
Introduction
How does Puritee RO water purifier work?
04
 Stage 3 – Pre-CB (Carbon Block) filter
The CB filter uses carbon block with high adsorption capacity which reduces harmful
chemicals including pesticides, volatile organic compounds, residual chlorine etc.
from water. It also adsorbs bad taste and odour causing organic compounds from
water.
Stage 4 – RO (Reverse Osmosis) membrane
RO membrane contains semi-permeable membrane wherein the water is passed
through the semi-permeable membrane to remove TDS (Total Dissolved Solids) and
heavy metals like Mercury, Arsenic, Copper, Lead etc. It also removes micro
organisms like bacteria, virus, protozoa and cysts.
Stage 5 – PAC (Post Activated Carbon) filter
After the RO membrane water is passed through post activated carbon which acts as
polisher and enhances the taste of water.

continuous beep till it is fixed.
• When the water pressure is lower than required water pressure limits, the power
button starts to blink continuously with the beep sound for 10 seconds till the water
pressure becomes normal.
Note: Call A. O. Smith Customer care centre, if you notice continuous blinking of Power light.

Auto flush indicator
This indicates flushing is in progress. Everytime the water purifier is switched ON the
auto flushing cleans the RO membrane. It enhances the life of RO membrane.
Note: Call A. O. Smith Customer care centre, if you notice continuous blinking of Auto flush
indicator.
RO change indicator
This indicates that the RO membrane and/or PAC filter needs to be replaced.
• RO change indicator glows when 10% life is remaining, indicating that it is time to
replace RO membrane and/or PAC filter.
• When RO membrane and/or PAC life reaches its end, this indicator will start to blink
continuously. The unit will not function until RO membrane and/or PAC filter is
replaced.
• When the system is switched ON every time, the buzzer beeps for 10 times and the
unit will not function until RO membrane and/or PAC filter is replaced.
Note: Call A. O. Smith Customer care centre, to replace the RO membrane and/or PAC filter.
Sediment & Carbon (SC) change indicator
This indicates that the Sediment filter and/or Carbon Block filter needs to be replaced.
• SC change indicator glows when 10% life is remaining, indicating that it is time to
change Sediment filter and/or Carbon Block filter.
• When Sediment filter and/or Carbon Block filter life reaches its end, this indicator will
start to blink continuously and the unit will not function until Sediment filter and/or
Carbon Block filter is replaced.
• When the system is switched ON every time, the buzzer beeps for 10 times and the
unit will not function until Sediment filter and/or Carbon Block filter is replaced.
Note: Call A. O. Smith Customer care centre, to replace the Sediment filter and/or Carbon Block filter.
