4.2 Cleaning and Replacing Quartz Sleeve
Note:
Minerals in the water slowly form a coating on the lamp sleeve. This coating must be removed because it reduces the
amount of UV light reaching the water, thereby reducing disinfection performance. If the sleeve can not be cleaned, it must
be replaced.
Prerequisites:
•
Shut off water supply and drain all lines.
•
Place a small pail under the unit to catch any spills.
•
Remove the UV lamp. Refer to
Section 4.1
.
Procedure:
Note:
If the system is put on a temporary by-pass or if it becomes contaminated after the disinfection system, it is necessary
to shock the system with household bleach for a full 20 minutes before resuming the use of the water.
