faulty. For instances like these, please follow the steps given below to
troubleshoot the problem without the help from a certified technician. If the
problem still persists, please call Customer care centre immediately.
Recommended input Feed water quality for the optimum
performance of your product
* Flow rates depends on variable factors such as feed water pressure, feed water characteristics
and condition of the membranes and filters.
** Recovery and TDS reduction percentages also depends on variable factors such as life and
condition of the membranes and filters, feed water pressure, feed water characteristics etc.
*** If input pressure exceeds 30 psi, a pressure reducing valve needs to be installed at the feed line.
If the pressure is lower than 7 psi, a booster pump needs to be installed. Ensure you buy them
from A. O. Smith Company authorised service technician.
Power plug must be used with a 230 V
outlet. It is recommended to connect
the product to the power supply only
with the plug that is provided with
the purifier. Do not pull out or touch
power plug with wet hands to avoid
electrical shock.
1. Turn ON the water connection
through the ball valve.
3. To dispense water from the
storage tank, push and hold the
water faucet lever.
4. To dispense water continuously,
lift up the water faucet lever for
the continuous water flow. To stop
the water flow, pull down the
water faucet lever.
2. Switch ON the power supply and
press the power button of the
purifier.
Make sure that the feed water is
tested before installation. Do not
install the product if the TDS and
Hardness are more than that
prescribed in the recommended feed
water conditions (Refer Page 12).
