7.22 ULTRA VIOLET (UV) WATER
TREATMENT SYSTEM
The UV water treatment system is made up of a power
supply with control panel, UV chamber that houses a
quartz sleeve and UV lamp, fan assembly and a UV
sensor. The power supply provides power and control
of the UV lamp inside the UV chamber. It gives a status
of lamp operation and life. The fan removes excess heat
from UV chamber when water in the chamber is not
flowing. The UV sensor measures the amount of UV
light or intensity at the external sensor. The sensor is
factory calibrated and is not field adjustable. This
sensor ensures the UV light intensity is above the
minimum for proper water treatment.
The power supply control panel pushbutton
description and LED status are shown in Figure 7-17.
