SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
Quartz Sleeve and UV Lamp Inspection –
When Packed in Tube
SMART UV®Disinfection Sterilizers are packaged
with their quartz sleeve assembly pre-assembled
inside the UV vessel.
The UV lamp is packaged separately in a corrugated
tube.
The Quartz Sleeve Assembly must be removed from
the UV vessel and inspected for damage prior to
installation. Extreme care should be used while this
procedure is being performed.
Note: DO NOT handle the lamp or quartz sleeve with
bare hands. Your hands can deposit oils on the quartz
sleeve and lamp that will decrease the efciency of
UV disinfection.
1. Carefully unpack the UV lamp from their corrugated
packing tube and inspect for damage including
broken glass, cracks, chips, fractures and pin
holes. If damage has occurred please contact the
place of original purchase immediately.
NOTE: Save the corrugated lamp packaging after
unpacking the UV lamp. Storing the lamp and/or
quartz sleeve in this packaging while performing
maintenance on the UV system will protect these
components from damage or fouling when outside of
the vessel.
2. Carefully, remove the quartz sleeve by unthreading
the Black Retaining Nut. Gently slide out the
quartz sleeve assembly and inspect for damage
including chips, cracks and pin holes. If damage
has occurred please contact the place of original
purchase immediately.
3. After inspection, reassemble the quartz sleeve
back into the UV vessel. Perform the Mandatory
Leak Test (see page 7).
4. Inspect all other UV system components (power
supply, UV vessel unions and necessary mounting
clamps) for damage.
After receipt and inspection of the unit, if broken
glass is found (including cracks, chips, pin holes
and hair line fractures of any kind) please contact
the place of original purchase immediately for
replacements.
PRE-INSTALLATION INSPECTION

SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
Improper assembly may result in water
damage to electrical components and unsafe
conditions. The manufacturer is not responsible for
damage cause by improper re-assembly of these
parts.
Quartz Sleeve Assembly Includes:
1. Quartz Sleeve
2. White Quartz Sleeve Retaining Nut
3. Rubber Gasket
4. Clear Quartz Sleeve Module
5. Clear Quartz Sleeve Module O-ring
6. Power Supply Gasket
Assembly Instructions
1. Position the white quartz sleeve retaining nut and
rubber gasket over the open end of the quartz
sleeve.
3. Slide the “open-end” of the quartz sleeve (with nut
and gasket in position) into the clear quartz sleeve
module.
3. Thread the white retaining nut onto the clear quartz
sleeve module’s male threads and hand-tighten.
4. While hand-tightening the white retaining nut onto
the clear quartz sleeve module, use your index
nger to ensure that the open-end of the quartz
sleeve mates smoothly with the inside lip of the
clear quartz sleeve module; this signies a good
t. See Photo A.
5. With the quartz sleeve positioned inside the
clear quartz sleeve module properly, nish hand-
tightening the white retaining nut. When the white
retaining nut is tight, the quartz sleeve should
appear straight inside the clear quartz sleeve
module (see Photo B).
NOTE: If the quartz sleeve appears crooked it may
leak. Disassemble and try again.
6. Carefully slide the quartz sleeve assembly into
the UV vessel (see Photo D). The domed-end of
the quartz sleeve should slide into the coupling
located on the non-electrical end of the UV vessel
(see Photo C).
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 E.
NOTE: Be sure that the clear quartz sleeve module
O-ring and gasket is properly seated in the bottom
of the quartz sleeve module (see item #6 on page 4).
INSTALLATION

SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
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 ow
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
lter, the unit's overall performance will be increased.
The efciency of the UV sterilizer operation is directly
related to the recommended water ow 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.
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
1½ times the vessel length. This will
allow sufcient 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 1½ times the vessel length. This
will allow sufcient room for servicing the unit and
replacing the UV lamp.
INSTALLATION

11
SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
Mounting the Power Supply
Depending on the style of power supply cylinder or
rectangle the SMART UV®system’s power supply can
be mounted two ways, mounting tabs at the corner
of the ballast or using the mounting clamps for the
cylinder type of ballast. The power supply should
always be mounted to a surface that is sheltered from
rain, splashing, heavy condensation or any other kind
of prolonged contact with water.
NOTE: DO NOT mount the power supply in an
extremely conned space where heat and moisture
can be retained.
Your UV system will include one of two different
power supplies based on the wattage of your unit:
• 50W, 80W and 120W UV systems include a
rectangular power supply. Four screws, one in
each corner of the power supply, secure the power
supply to the wall or shelf.
• 150W UV systems include a cylindrical power
supply that must be mounted with the two pipe
clips packaged with the unit.
A single screw at the base of the pipe clip secures it
to the wall or shelf. The power supply is then locked
into the pipe clip by securing the retaining strap onto
the clip.
Mandatory Leak Test
A leak test should be performed each time the quartz
sleeve is installed inside the unit’s vessel or when the
quartz sleeve or gaskets are replaced [Once annually].
Performing a leak test is a precautionary measure
that will determine whether or not the critical seal
between the quartz sleeve and quartz sleeve module
has been achieved.
Failure to achieve a proper quartz sleeve/quartz
sleeve module seal during SMART UV Disinfection
Sterilizer operation will allow water to leak into the
inside of the quartz sleeve, potentially damaging the
UV lamp and other electrical components, which
could develop into dangerous situations.
IMPORTANT NOTE: Failure to perform a leak test
could lead to conditions that will void your product
warranty.
To Perform Mandatory Leak Test:
1. Prepare the UV system for permanent operation
by plumbing it in-line, into a lter system using the
plumbing hardware of your choice. If PVC glue is
used, follow the glue manufacturer’s instructions.
2. If UV lamp is installed, with the unit plumbed for
operation and the clear quartz sleeve module
securely in place, remove the UV lamp from the
quartz sleeve module.
3. Roll-up a few paper towels creating a core
approximately 3/4inch diameter, 10-inches long
then slide into the open quartz sleeve module port.
Insert about 6-inches of the paper towel core down
into the quartz sleeve, as shown.
4. With the paper towel in place, turn on the pump
and recirculate water through the UV vessel for at
least thirty (30) minutes.
5. After thirty (30) minutes of recirculating water
through the UV vessel, remove the paper towels
from the quartz sleeve module. Inspect closely for
moisture. If the paper towel is completely dry, your
leak test is complete and successful.
If moisture is detected on the paper towel the quartz
sleeve’s rubber gasket and O-ring have failed to
achieve a seal and must be re-assembled; repeat
the leak test until a seal is achieved. See page 4 for
assembly instructions.
INSTALLATION

SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
INSTALLATION
Electrical Requirements
The electrical requirements for the UV sterilizer are
marked on the unit’s power supply label (Ex. 120VAC
50/60Hz.). The unit must be plugged into a well-
grounded electrical outlet.
Do not attempt to cut the ground post
off of the 3-prong plug, doing so will void the unit’s
warranty.
This product must be grounded. If the unit should
fail electrically, grounding provides a path of least
resistance for electric current to pass to reduce
the risk of electric shock. This product’s cord is
equipped with an equipment-grounding conductor
and a grounding plug. The plug must be plugged
into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and
ordinances. If in doubt consult a qualied electrician.
DO NOT operate this equipment with
timing devices.
Improper connection of the equipment-
grounding conductor can result in a risk of
electrocution. Check with a qualied electrician or
service personnel if unsure that the outlet is properly
grounded. Do not product’s plug. If it will not t into
the electrical outlet, have a proper outlet installed by
a qualied electrician. Type of plug adapter with this
product.
Ground Fault Circuit Interrupter
(GFCI) Protection
This unit must be wired in conjunction
with a properly grounded, Ground Fault Circuit
Interrupter (GFCI). Only three (3) wire grounded
cables suitable for outdoor use should be used to
connect this unit. If joining cables for outdoor use, a
suitable watertight cable connector must be used. If
an extension cord is necessary, a cord with a proper
rating should be used. A cord rated for fewer amperes
or watts than the appliance’s rating may overheat.
Care should be taken to arrange the cord so that it
will not be tripped over or pulled. If in doubt consult a
qualied electrician.
GFCI’s are designed to sense an imbalance in
electrical current ow within the main electrical leads
(leakage current). When this imbalance (maximum 5
mA per UL) occurs in the main leads, a comparator
within the GFCI outlet generates a trip signal which is
applied to a coil that trips the main (normally closed)
contacts. These contacts open and break the circuit.
Ghost Trips
Consider that all GFCI’s must trip at a leakage current
of 5 ma. GFCI “Ghost Trips” are caused by electrical
devices that have small electrical leakage current to
ground. Multiple outlets protected by one GFCI allow
for potential cumulative leakage currents caused by
multiple appliances each leaking small amounts of
current.
Example: One pump plugged into an outlet that is
part of a four outlet branch protected by one GFCI
will not trip the GFCI with its 2 mA leakage current.
However, two pumps and a UV with a cumulative
leakage current of 7 mA will trip the GFCI. This is a
common problem.
The solution to the GFCI “Ghost Trip” problem is to
operate the device on its own GFCI protected outlet,
or, remove other devices from the GFCI protected
branch of outlets. If the GFCI is over ten years old,
you may want to consider replacing it.
UV Lamp Installation
Lamp Styles
UV lamps are manufactured with color coded ceramic
bases. White-capped UV lamps signify a Standard-
Output UV lamp while red-capped UV lamps signify a
High-Output UV lamp.
Power Cord Adjustment
There should be 4-inches of cord between the Gray
Adapter (3) and the 4-pin Lamp Connector (1). The
4-inch cord distance positions the lamp properly
inside the quartz sleeve.
1. The 3/8inch Threaded Watertight Cord Connector
(1) is adjustable. Loosen it gently move the cord
through it. Care must be taken when retightening.
If the Connector’s Rubber Gasket Seal is dislodged
during cord adjustment please make sure that it
is properly re-seated inside the male threaded
portion of the connector.
4 Inches between Gray Adapter (3) and 4-Pin Connector (4)

SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
INSTALLATION
2. After a successful leak test and without the power
supply connected to a control box, attach the
lamp’s 4-pins to the power cord’s white 4-pin
Connector (4), then slide the UV lamp back into the
quartz sleeve.
3. Whether the SMART UV®Disinfection Sterilizer
vessel is mounted horizontally or vertically, care
should be taken when installing the UV lamp into
the vessel’s quartz sleeve. Vertical installations
require extra attention to eliminate the chance
of the lamp dropping into the quartz sleeve and
breaking.
4. With the UV lamp/power cord connection complete
and the lamp entirely inside the quartz sleeve,
carefully screw down the Gray Power Supply
Adapter (3) onto the Clear Quartz Sleeve Module
(6); hand tighten only.
5. Screw down the Black Power Supply Jamb Nut (4)
until it makes contact with the Clear Quartz Sleeve
Module (6).
NOTE: By loosening the 3/8inch Threaded Watertight
Cord Connector (5), Power Cord adjustments can be
made. Make sure the 3/8inch Threaded Watertight
Cord Connector’s gasket is properly in place before
retightening.
NOTE: If you do not have the Black Power Supply
Jamb Nut (4) back far enough before tightening the
Gray Power Supply Adapter (3), the gray adapter
will not make contact with the power supply gasket
and will enable outside moisture to enter the quartz
sleeve assembly and cause a system failure.

OPER ATION
SMART UV®Installation and Operation
SMART UV Systems UV Sterilizers are used in
a variety of applications to control waterborne
pathogens. Pentair encourages the consideration of
the installation/operation recommendations provided
here.
Suspended solid waste will absorb UV light and
reduce the UV transmittance through water. By
operating the SMART UV after the mechanical lter,
the unit’s overall performance will be increased.
When operating SMART UV sterilizers please
consider the recommended water ow rates.
Pond Installation Congurations
Small to Moderately Sized Ponds (up to 5,000
Gallons) Using Skimmers and Falls
Placing the UV between the skimmer box and the
lter ensures that pre-ltered water reaches the
UV, increasing its performance while reducing
maintenance.
Often the capacity of the pump exceeds the capacity
of the UV. If this is the case, install a bypass manifold.
Be sure that the skimmer is equipped with mechanical
ltering capacity. See Diagram 1.
NOTE: Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE: Use threaded seal tape on all threaded
connections.
Larger Sized Ponds (above 5,000 Gallons) Using
Surface Skimmer and Pressurized Filter
This system is simple yet it achieves critical ltering
goals, such as good water circulation for increased
solid waste suspension. The bottom drain/surface
skimming capabilities ensure maximum waste
removal. See Diagram 2.
The SMART UV System UV Sterilizer is positioned
after the mechanical lter where it can receive only
solid waste free water, optimizing UV transmittance/
performance. Notice the 3-way valve that regulates
suction from the skimmer and drain to the pump,
allowing ow control.
Next, multiple “clean water returns” improve
circulation, suspending solid waste and helping it to
nd the lter. If you have a ow rate that exceeds the
UV’s, install a by-pass manifold. See Diagram 1.
NOTE: Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE: Use threaded seal tape on all threaded
connections.
Aquarium Installation Congurations
Canister Filter/Aquarium Installation
Pressurized Canister lters are commonly used with
small freshwater/saltwater aquariums. Diagram 3
shows a SMART UV model.
It is important to match the Canister Filter’s ow rate
to the capacity of the SMART UV. If this is not feasible,
use a bypass manifold (see Diagram 5 on page

a check valve or ball valve (see lter instructions/
recommendations). See Diagram 3.
NOTE: Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE: Use threaded seal tape on all threaded
connections.
Wet-Dry with External or Submersible Pump
Installation
This installation conguration shows the SMART
UV System®UV Sterilizer capacity matched to the
recirculating ow rate performance of the pump.
We recommend mechanical lter media being used
inside the over-ow and at the top of the wet-dry
lter.
Installing a check valve after the UV will eliminate back
siphoning. Installing true-union ball valves will allow
ow adjustments and UV removal. For best results,
install a saddle-style water ow meter, mounted
horizontally on the outlet side of the UV. Follow the
water ow meter manufacturer’s instructions for
proper installation and operation. See Diagram 4.
NOTE: Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE: Use threaded seal tape on all threaded
connections.
Wet-Dry w/External or Submersible Pump
Installation
This installation conguration is identical to Diagram
4 with the addition of a bypass manifold. The bypass
is used to deliver a precise water ow to the SMART
UV when the overall clean water return ow rate
exceeds the UV’s capacity.
Installing a check valve after the UV will eliminate
back siphoning. Installing true union ball valves will
allow ow adjustments and easy UV removal for
servicing. For best results, install a saddle-style water
ow meter, mounted horizontally on the outlet side of
the UV. Follow the water ow meter manufacturer’s
instructions.
NOTE: Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE: Use threaded seal tape on all threaded
connections

MAINTENANCE
Quartz Sleeve Cleaning
It is recommended that the quartz sleeve be visually
inspected for cleaning once every six months of
operation. Even the slightest layer of material (slim/
dirt) coating the outside of the quartz sleeve can
have a substantial effect on UV-C light transmittance
through the glass and into the water.
Cleaning frequency is also dependent on how well
water is being ltered before reaching the SMART
UV®Systems UV Sterilizer. Water that contains solid
waste will deposit greater amounts of material onto
the quartz sleeve and will increase the frequency of
necessary cleaning.
To Clean the Quartz Sleeve (for above water-level
installations only):
1. Disconnect power to the UV sterilizer and pool
pump at the circuit breaker.
2. Relieve any residual pressure that may remain in
the system.
3. Unthread the Black Retaining Nut and gently
remove the Quartz Sleeve Assembly and lamp
from the UV vessel.
4. Inspect the Quartz Sleeve and clean as needed
with a soft, clean cloth.
5. If calcium deposits are present use vinegar or
a mixture of water and muriatic acid to dissolve
the deposits. If using muriatic acid a ratio of four
parts water to one part acid should sufce. Always
introduce acid to the water and never introduce
the water to the acid.
Muriatic acid is corrosive and can lead
to inammation or burns to body tissue.
ALWAYS wear rubber gloves, safety
glasses and an N-95 dust mask when
handling acid to prevent serious bodily
injury.
To prevent degradation of the acid by UV
light, store muriatic acid in an opaque
container and away from direct sunlight.
6. Remove ALL vinegar or acid from the quartz sleeve
assembly before reassembling.
Winterizing
Using the SMART UV Disinfection Sterilizer in
extremely cold temperatures can cause damage to
the unit, especially if the water is allowed to freeze
inside the equipment. Please note that damage to
the product due to freezing is not covered under
warranty.
Pentair recommends shutting the UV system down
when the temperature consistently falls below 40°F
(4°C).
1. Drain all water from the UV system.
2. Disassemble the entire unit and carefully clean
both the outside and interior of the UV body and
components.
3. Once clean and dry, store the UV vessel and power
supply in a dry place for the winter.
4. Return the UV system to service when temperatures
consistently return to 40°F (4°C) or greater.
NOTE: Be sure to replace the quartz sleeve gasket and
perform a leak test prior to operating the equipment.

MAINTENANCE
Lamp Connector Removal
In the event that you would need to replace you
4-pin lamp connector, follow these steps:
1. Unplug the UV sterilizer and disconnect power to
the water pump at the circuit breaker.
2. Remove UV lamp from the quartz sleeve.
3. Unplug the UV lamp from the connector/power
cord.
4. Grasp the white 4-pin lamp connector with a pair of
pliers while standing on the power cord itself.
5. Pull hard, while twisting slightly. The connector will
disconnect.
6. Check to be sure the ends of the electrical wires
are still tinned; they are pre-soldered before they’re
pushed into the connector. If they are no longer
tinned, you will need to dip them in ux and then
solder to make them rm enough to push back in
the new lamp connector.
NOTE: Clean away any residual ux off of the wires
before assembling them into the lamp connector.
7. Using a “new” 4-pin lamp connector, push the
power cord’s tinned wires into the holes of
the connector making sure that they are rmly
attached. Once attached, the wires should not pull
out of the connector. See Diagrams below for wire
placement.
8. Plug lamp back into the connector.
9. When installing the lamp be sure to have Black
Power Supply Jam Nut all the way back on gray
adapter. Tighten down the Gray Power Supply
Adapter rst and then secure the black jam nut.
See “UV Lamp Installation” on page 9.
NOTE: If you do not have the Black Power Supply
Jam Nut back far enough before tightening the Gray
Power Supply Adapter, the gray adapter will not make
contact with the power supply gasket and will enable
outside moisture to enter the quartz sleeve assembly
system failure.

TROUBLESHOOTING
Paper Towel Leak Test Indicates a Leak
1. Turn off the pool pump at the circuit breaker and be
sure all ow to the unit has been stopped.
2. Refer to pages 4–5 for “Quartz Sleeve Assembly”
and page 8 for “UV Lamp Installation” (in reverse
order) to disassemble the unit.
3. Ensure there are no cracks or breakages in the

properly installed, and that the Quartz Sleeve
Retaining Nut has been tightened down completely.
4. Reassemble the Quartz Sleeve (see page 4) and
repeat the Mandatory Leak Test (see page 7) until
there is no indications of a leak.
GFCI/Breaker is tripping
1. Immediately disconnect power to the SMART UV®
Disinfection Sterilizer.
2. Turn off the pool pump at the circuit breaker and be
sure all ow to the unit has been stopped.
3. Refer to pages 4–5 for “Quartz Sleeve Assembly”
and page 8 for “UV Lamp Installation” (in reverse
order) to disassemble the unit.
4. Check for water/moisture inside the quartz sleeve.
5. Multiple appliances connected to a circuit protected
by one GFCI create the potential for cumulative
leakage current resulting in a tripped GFCI.
Pond Still Green after a Week of UV
Operation
1. Ensure the UV lamp is lit by utilizing the safe
viewing port.
2. A dirty quartz sleeve can reduce the UV sterilizer’s
performance. If the Quartz sleeve is dirty refer to
“Quartz Sleeve Cleaning” on page 15 for cleaning
procedures.
3. Double check the unit’s ow rate and compare to
the ow rate chart for your specic UV model.
