7. With the quartz sleeve assembly properly in place, the quartz sleeve retaining module
should sit ush against the top of the UV vessel. See Photo G.
Note: Be sure that the clear quartz sleeve module o-ring is properly seated in the bottom of
the quartz sleeve module (see item #6 on page 4).
8. Thread the black retaining nut (see Photo H) onto the male threads of the UV vessel. Hand
tighten only!
9. Using the instructions given on page 7, perform the Mandatory Leak Test. If no leaks are

Sterilizer Installation and Operation
Bioshield
®
UV Disinfection Sterilizers are used in a variety of applications to control waterborne pathogens. Pentair
encourages the consideration of the installation recommendations provided here.
Suspended solid debris will absorb UV light and reduce the UV transmittance through water. By operating the Bioshield
UV system after the mechanical lter, the unit’s overall performance will be increased.
When operating UV sterilizers please consider the recommended water ow rates found in the “Sizing Chart”, on page 1.
Typical Installation
(See Diagram Below)
This system achieves critical ltering goals, such as good water circulation. The bottom drain/surface skimming capabilities
ensure maximum debris removal.
The UV Sterilizer must be positioned after the mechanical lter where it can receive only solid debris free water, optimizing
UV transmittance/performance. If you have a ow rate that exceeds the UV vessels rated ow, install a bypass loop.
Note: Before gluing pipe or reducer bushing into the UV vessel’s union or socket, remove the quartz sleeve assembly to
prevent glue from dripping onto the quartz sleeve.
Note: Use thread seal tape on all threaded connections.
