Cautions for Filter Replacement
• According to the filter replacement cycle, replace filters regularly.
• If the filter is not regularly replaced, it could degrade the water quality.

and consumption.
• When replacing filter, use our original filters for this product. If not,
A.O.Smith can not guarantee filter efficiency and water quality.
• When replacing filters, be sure to ask service man to do flushing process
to new filters for more than 10 mins. (If not, it could degrade water
quality).
• Even if your water consumption is not much, following regular filter
replacement cycle is recommended.
• Above filter replacement cycles are based on normal feed water
condition and 1500 liters of water purifying efficiency.

• A.O.Smith can not take responsibility for any damage caused
by replacing filters by a third party.
