Remaining lifespan countdown of UV lamps (in days)

The system counts down the number of days until a UV lamp change is required.
At 30 days remaining, the operating display screen will change to a yellow warning indicator. At 7 days
remaining, the UV unit will additionaly repeat an audible alarm sound. In the event that the zero-day
threshold limit has been exceeded, the display screen changes to solid red and a continuous buzzer
will be output.
At any point during this sequence, the warning tone or alarm screen can be deferred for seven days by holding
the controller button down for a period of five seconds. The number of deferrals used will be displayed as below.
Once the deferral expires, the alarm will sound once again. The deferral can be repeated up to three times.
OBSERVE: At any point after lamp expiration, the water may be unsafe for consumption and should not
be consumed without another form of disinfection.

UV lamp replacement

After the UV lamp is expired, it must be replaced with the identical part number as indicated on the
"Maintenance Parts screen" or on the label on the reactor (with the same serial number and number of
watts). With the system powered down, remove and discard the UV lamp key from the controller. The
replacement lamp is packaged with a lamp key on the connector at the end of the lamp. Remove the
key from the lamp and place it in the controller. Refer to Installation, starting with step 11 (Chapter 7 on
page 13) for instructions on installing the new lamp.
