DANGER
CAUTION
WARNING

 Stage 3 – Pre Carbon filter
The Pre Carbon filter uses carbon block with high adsorbtion 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 microorganisms
like bacteria, virus, protozoa and cysts.
Stage 5 – MIN-TECH (Mineraliser Technology)
The MIN-TECH contains Calcium and Magnesium minerals which helps to improve
the taste and quality of water. It adds the required essential minerals back to water
and balances the pH of water.
Stage 6 – Silver Activated Post Carbon
Water is passed through Silver Activated Post Carbon filter which acts as polisher and
enhances the taste of water.
Stage 7 – SCMT filter (Silver Charged Membrane Technology)
In the final stage water is passed through SCMT filter which ensures double
purification of water making it Pure & Sure for drinking.
Puritee+™ water purifier uses one of the latest technologies used in water purification
process. Puritee+™ water purifier works under the principle of RO (Reverse Osmosis)
technology which is found to be one of the most effective process. 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+™water purifier has 7 stages of purification system, wherein the water is
passed through the various stages and progressively filtered to get purified water which
is stored in the inbuilt storage tank.
 Stage 1 – Pre-filter
The Pre-filter is used to remove physical contaminants such as dirt, dust, soil
particles, turbidity present in the water. This improves the life of the Sediment filter.
 Stage 2 – Sediment filter
The Sediment filter is used to remove fine and coarse physical contaminants present
in the water. This improves life of the Pre Carbon 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.
• Microorganisms such as pathogenic bacteria, virus, protozoa and cysts.
Puritee+™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. Puritee+™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.

This indicates flushing is in progress. Every time the water purification process is
activated the auto flushing mechanism 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.
Auto flush indicator
This indicates that the MIN-TECH, Silver Activated Post Carbon, SCMT filter and/or
RO membrane needs to be replaced.
• RO change indicator glows when 10% life is remaining, indicating that it is time to
replace MIN-TECH, Silver Activated Post Carbon, SCMT filter and/or RO membrane.
• When MIN-TECH, Silver Activated Post Carbon, SCMT filter and/or RO membrane life
reaches its end, this indicator will start to blink continuously. The unit will not
function until MIN-TECH, Silver Activated Post Carbon, SCMT filter and/or RO
membrane are replaced.
• RO change indicator keeps blinking continuously with the buzzer beeping for
10 times every time the system is switched ON. The unit will not function until
MIN-TECH, Silver Activated Post Carbon, SCMT filter and/or RO membrane are
replaced.
