2.2 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 disinfection performance. If the sleeve can not be cleaned, it
must be replaced.
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
Procedure:
Notes:
1) After replacing the UV lamp or quartz sleeve perform the disinfection procedure; refer to Owner’s Manual.
2) 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 water.
