4.3 Cleaning and Replacing UV Sensor (if applicable)
The UV sensor is very delicate instrument. Extreme care is required when handling and cleaning. The sensor window itself is constructed from quartz
which is extremely fragile, be careful you do not chip or break this quartz window. Manufacturer's warranty does not cover damage due to neglect or
misuse.
Mineral deposits and sediment may accumulate on the sensor window decreasing the UV energy detected. Good
maintenance of pre-treatment equipment will reduce the accumulation of residues. If the system indicates that the UV
intensity is low, one cause may be a stained quartz sleeve and/or sensor window.
Prerequisites:
• Remove and clean the quartz sleeve.
Note: The quartz sleeve and UV sensor should be cleaned at the same time.
Procedure:.
1
• Disconnect the UV sensor from
the controller by disconnecting the
sensor cable.
Section 5 Operation
The advanced warning system has been installed to provide the optimum protection against microbiological contamination in water. DO NOT disregard
the warning signals. The best way to ensure optimum UV performance is to have the water microbiologically tested by a recognized testing agency on
a regular basis.
