Lamp Timer Operation (for models prior to February 2011 ONLY):
The annual lamp change reminder timer will run for approximately one full year.
At the end of this one-year period, the lamp change timer will flash and the
buzzer will sound. The flashing
red
LED indicates that the timer function has
entered its 28-day grace period. Pushing the timer button during this grace period
will silence the alarm buzzer for a seven-day period but the
red
LED will continue
to flash. The buzzer reset can be activated a maximum of four times during the
28-day grace period. Under no circumstances does the grace period exceed 28-
days. At the expiry of the grace period the UV power source indicates the lamp
change alarm by illuminating the
red
timer LED continuously and sounding the
buzzer.
Note
: The UV lamp is not shut down in this alarm mode and the solenoid
valve drive is not disabled.
Time Remaining (for models prior to February 2011 ONLY):
When the lamp change reminder timer is not in the 28-day grace period or lamp
change alarm mode, the number of months of lamp life remaining can be
determined by pressing the timer push button and counting the number of times
the
red
timer LED flashes. See “Resetting of Lamp Change Timer” in the
Operating and Maintenance section following.
