Lamp Countdown Sequence
The system counts down the number of days until a lamp change is required.
At seven days remaining, the screen changes to a yellow caution screen with an audible chirp ev-
ery 15 seconds. Past the zero day threshold, the screen changes to solid red and cycles between
a red “lamp expired” screen and a “water may be unsafe for consumption” screen. The same
intermittent audible chirp is heard throughout this lamp expired sequence.
At any point during this sequence, the audible chirp can be deferred by holding the controller
button down for a period of five seconds, after which the screen below will be displayed. After
the seven days deferral expires, the alarm will sound once again. The deferral can be repeated
as many times as you wish.
PLEASE NOTE:
At any point after lamp expiration, the water may
be unsafe for consumption and should not be consumed without another form of disinfection.
Lamp Countdown Reset Sequence
When changing the lamp, the day countdown timer must be reset to match the newly installed
lamp. To reset, firmly hold down the button on the controller while plugging the power cord back
into the outlet. Continue holding down the button for five seconds as indicated until you hear an
audible chirp confirming the timer has been reset. The following two screens will be displayed
during this process.
