2.3 Cleaning and Replacing UV Sensor
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:
•
Disconnect the main power source and allow the system to cool for 10 minutes.
•
Shut off water supply and drain all lines.
•
Depressurize the unit. Place a small pail near the openings to catch any spills.
•
Remove the UV lamp. Refer to
•
Remove and clean the quartz sleeve. Refer to
Note:
The quartz sleeve and UV sensor should be cleaned at the same time.
Procedure:.
WA R N I N G
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.
