1) The filter is about to expire. Check the indicator reminder to
confirm and replace it.
2) The system hasn't been used for a while. Turn on the RO faucet and
allow it to flush for a while before drinking.
What will happen if I do not change my filter when the filter life
indicator light turns red?
Over-used filters will degrade the filtration performance, causing
contaminants to leak back into the water and adversely affect your
health. It's recommended that you replace the filter if the filter
life indicator light turns red.
Why is the filter life indicator light still red after I changed the
filter?
You have not reset the filter life indicator. Please reset it: Press
and hold the CF filter life indicator for 7 seconds, until the system
beeps and the blue light stays on.
