UV Lamp Replacement
The ultraviolet lamp requires periodic replacement. Lamp
life will vary according to the number of times the
DIamond TII is turned on and off. Lamp life is based on
the DIamond TII being operated in the normal recirculat-
ing mode during regular working hours and then placed in
the Standby mode during off hours. Every fourth time the
pump goes on in the Standby mode, the UV light will go
on. If the DIamond TII is cycled between the RUN and
STANDBY modes during the workday, this will result in a
shorter lamp life. Therefore, it is recommended that the
DIamond TII be left in the normal RUN mode during regu-
lar working hours.
To replace the UV lamp see “UV Lamp Installation” proce-
dure in this manual.
