OPERATING INSTRUCTIONS
Successful Installation of a new Filter
When the depleted filter is replaced with a new filter
three beeps are sounded and the 100% filter life is dis-
played momentarily. The new filter has been success-
fully installed and the electronic indicator has reset.
Percent of Filter Life Remaining
As the filter is used the indicator counts down to zero
from 100%. The percentage remaining is displayed
when water is being filtered. Additionally, the filter sta-
tus can be checked without the faucet being turned on
by momentarily pressing the filter button.
Filter is Actively Filtering Water
The water drop icon cycles when water is
being filtered.
Low Filter Warning
There are two low filter warnings, one at 5% remaining
filter life and 1% remaining life. When the remaining
filter life reaches 5% the low filter icon blinks and three
beeps are sounded when the filter button is depressed.
At 1% or less the low filter icon blinks and beeps are
sounded every 5 seconds while water is being filtered
indicating it is time to change the filter.
Depleted Filter Warning
When the filter life remaining reaches 0%, the depleted
filter icon blinks and beeps are continuously sounded
while water is being filtered. The filter mode should not
be used until a new filter is installed.
Low Battery Warning
A standard 3V lithium watch battery designed to last
several years under normal usage powers the electronic
indicator. When a low battery condition is detected the
low battery icon blinks and beeps are sounded while
water is being filtered indicating it is time to change
the battery.
