UV Sensor Cleaning / Replacement
Mineral deposits and sediment may accumulate on the sensor window over time, decreasing the UV
energy detected. If the UV controller indicates that the UV intensity is low, one cause may be a stained
quartz sleeve and / or sensor window.
WARNING:
The UV sensor is an extremely sensitive and fragile instrument. Extreme care
is required when handling. The sensor window is constructed from quartz, which is
extremely fragile. Use caution when handling the sensor to ensure that you do not chip or
break this quartz window.
Prerequisites:
Remove and clean the quartz sleeve.
NOTE:
The
quartz sleeve and UV sensor should be cleaned at the same time.
Disconnect the UV sensor
from the controller by
disconnecting the sensor
cable.
Remove the UV sensor by
grasping the body of the
sensor and rotating it
counter-clockwise.
Submerge only the end of
the sensor in the
commercial scale remover
for 30 minutes.
Clean the sensor with a
cotton swab and spray
with water.
Re-insert the UV sensor
until a water-tight seal is
achieved.
