4.2 Cleaning and Replacing Quartz Sleeve
Note: Minerals in the water slowly form a coating on the quartz sleeve. This coating must be removed because it reduces
the amount of UV light reaching the water, thereby reducing performance. If the sleeve can not be cleaned, it must be
replaced.
Prerequisites:
• Shut off water supply and drain all lines.
• Depressurize the unit. Place a small pail under the unit to catch any spills.
• Remove the UV lamp. Refer to
Section 4.1.
Procedure:
Notes: 1) After replacing the UV lamp or sleeve perform the cleaning procedure, refer to
Section 3.2.
2) If the system is put on a temporary by-pass or if it becomes contaminated, it is necessary to complete the cleaning
procedure. Refer to
Section 3.2.
