INSTALLATION
8. Thread the black retaining nut (see Photo F) onto
the male threads of the UV vessel. Hand tight only!
9. Using the instructions given on page 7, perform the
Mandatory Leak Test. If no leaks are found proceed
to page 8, UV Lamp Installation, for instructions on
installing the UV lamp.

Sterilizer Installation and Operation

DO NOT operate the UV system at flow
rates higher than 90 GPM (341 LPM). Operating the
product in this manner may result in product failure
and voiding of warranty.
SMART 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 SMART UV system after the mechanical
filter, the unit's overall performance will be increased.
The efficiency of the UV sterilizer operation is directly
related to the recommended water flow rates found
in the "Sizing Chart", on page 1.

Mounting the Vessel

Note: The way UV vessels are mounted/positioned
plays a very important role in the unit's performance
and degree of safety. We STRONGLY RECOMMEND
that you follow these instructions and guidelines
precisely. Any deviation from these mounting
instructions will void any warranty associated with
the UV vessel and all its components and may cause
unsafe conditions.
Trapped air inside the UV vessel during
operation may create excessive heat thus damaging
internal components.
SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
Vertical Vessel Mounting
Mount the SMART UV Disinfection
Sterilizer with the electrical end up.
Use the bottom port as the inlet
with the top port as the outlet.
Note: The UV vessel should be
installed with a vertical clearance
11/2 times the vessel length. This will
allow sufficient room for servicing
the unit and replacing the UV lamp
The inlet and outlet
plumbing MUST be supported to
avoid vessel material stress.
Failure to support the inlet and outlet plumbing may
lead to damage to the vessel.
Horizontal Vessel Mounting
Mount the SMART UV system horizontally with the
inlet/outlet facing up. If the unit is mounted but
not level, the electrical end of the unit should be
positioned higher than the non-electrical end. Choose
the lower port of the inlet
NOTE: The UV vessel should be installed with a
horizontal clearance 11/2 times the vessel length. This
will allow sufficient room for servicing the unit and
replacing the UV lamp.
