PRE-INSTALLATION INSPECTION
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 must 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 eciency of
UV disinfection.
1. Carefully unpack the UV lamp from its 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. After inspection, reassemble the quartz sleeve
back into the UV vessel. Perform the Mandatory
Leak Test (see page 12).
3. 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.

INSTALLATION
7. With the quartz sleeve assembly properly in place,
the quartz sleeve retaining module will sit ush
against the top of the UV vessel.
NOTE: Be sure that the clear quartz sleeve module
gasket is properly seated in the bottom of the quartz
sleeve module.
8. Thread the black retaining nut onto the male
threads of the UV vessel. Hand tight only!
9. Using the instructions given on page 12, perform
the Mandatory Leak Test. If no leaks are found
proceed to page 13, UV Lamp Installation, for
instructions on installing the UV lamp.
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.
Sterilizer Installation and Operation
DO NOT operate the UV system at ow
rates higher than the suggested maximum ow rates.
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.
Note: The UV vessel must be installed with a vertical
clearance 1½ times the vessel length. This will allow
sucient room for servicing the unit and replacing
the UV lamp and/or quartz sleeve.
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.
SMART UV® U V DISINF ECTION STERILIZER Ins tallation and User 's Guide
INSTALLATION
11
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 must be positioned
higher than the non-electrical end.
NOTE: The UV vessel must be installed with a
horizontal clearance 1½ times the vessel length. This
will allow sucient room for servicing the unit and
replacing the UV lamp and/or quartz sleeve.
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 must
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 conned space where heat and moisture
can be retained.
Your UV system will include one of two dierent
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.
SMART UV® U V DISINF ECTION STERILIZER Ins tallation and User 's Guide

INSTALLATION
Mandatory Leak Test
A leak test must 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,
minimum]. 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.
5. If moisture is detected on the paper towel the
quartz sleeve’s rubber gasket has failed to achieve
a seal and must be re-assembled; repeat the
leak test until a seal is achieved. See page 9 for
assembly instructions.
Electrical Requirements
The electrical requirements for the UV sterilizer
are marked on the unit’s power supply label
(Ex. 120/240VAC 50/60Hz.). The unit must be plugged
into a well-grounded electrical outlet.
Do not attempt to cut the ground post
o 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 qualied electrician.
DO NOT operate this equipment with
timing devices.
3. Roll-up a few paper towels creating a core
3
approximately
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. 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 towels are completely dry,
the leak test is successful.
/
4 inch diameter, 10-inches long
Improper connection of the equipmentgrounding conductor can result in a risk of
electrocution. Check with a qualied electrician or
service personnel if unsure that the outlet is properly
grounded. Do not alter the product's plug. If it will
not t into the electrical outlet, have a proper outlet
installed by a qualied electrician.

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 must 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 must be used. A cord rated for fewer amperes
or watts than the appliance’s rating may overheat.
Care must be taken to arrange the cord so that it will
not be tripped over or pulled. If in doubt consult a
qualied 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 StandardOutput UV lamp while red-capped UV lamps signify a
High-Output UV lamp.
A 4” Space between 4-Pin (4) and Gray Power Supply
Adapter (3) must be maintained. The proper positioning
is important for UV eectiveness.
1. The 3/8-inch 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.
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. Then slide the UV lamp back into the
quartz sleeve.
3. Care must 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 tighten down the Gray Power Supply
Adapter (2) onto the Clear Quartz Sleeve Module
hand tighten only.
5. Tighten down the Black Jamb Nut (3) until it makes
contact with the Clear Quartz Sleeve Module.
NOTE: If you do not have the Black Jamb Nut (3)
back far enough before tightening the Gray Power
Supply Adapter (2), 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.

OPERATION
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 Congurations
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.
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.
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.
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 Congurations
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
15). To prevent back-siphoning, consider installing
SMART UV® U V DISINF ECTION STERILIZER Ins tallation and User 's Guide
OPERATION
15
a check valve or ball valve (see lter instructions/
recommendations). See Diagram 3.
Installing a check valve after the UV will eliminate back
siphoning. Installing true-union ball valves will allow
ow adjustments and UV removal. 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: 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 conguration 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.
NOTE: Use threaded seal tape on all threaded
connections.
Wet-Dry w/External or Submersible Pump
Installation
This installation conguration 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 (slime/
dirt) coating the outside of the quartz sleeve can
have a substantial eect 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 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 suce. Always
introduce acid to the water and never introduce
the water to the acid.
Muriatic acid is corrosive and can lead
to inammation 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.
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. Close the bypass valves so any water ow will
bypass the UV and prevent additional water from
entering the UV body over the winter.
2. Drain the UV via the drain plug.
3. Remove the UV and pour out the remaining water
from the body through one of the open ports.
4. Skipping step 3 for vertical installations will leave
the quartz sleeve submersed in approximately
1.25 inches of water which when frozen will break
the quartz sleeve and will not be covered under
warranty.
5. Reinstall the UV.
6. Upon restart of the system in the spring, seal kit
replacement is required.
7. See the applicable table in the Replacement Parts
section for the appropriate part number for the
seal kit associated with your version of UV.
NOTE: Be sure to replace the quartz sleeve gasket and
perform a leak test prior to operating the equipment.
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.

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 o 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 must 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 13.
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
and potentially cause system failure.

TROUBLESHOOTING
Paper Towel Leak Test Indicates a Leak
1. Turn o the pump at the circuit breaker and be sure
all ow to the unit has been stopped.
2. Refer to page 9 for “Quartz Sleeve Assembly”
and page 13 for “UV Lamp Installation” (in reverse
order) to disassemble the unit.
3. Ensure there are no cracks or breakages in the
Quartz Sleeve, that the Quartz Sleeve Gasket is
properly installed, and that the Quartz Sleeve
Retaining Nut has been tightened down completely.
4. Reassemble the Quartz Sleeve (see page 9) and
repeat the Mandatory Leak Test (see page 12) until
there is no indications of a leak.
GFCI/Breaker is tripping
1. Immediately disconnect power to the SMART UV®
Disinfection Sterilizer.
2. Turn o the pump at the circuit breaker and be sure
all ow to the unit has been stopped.
3. Refer to page 9 for “Quartz Sleeve Assembly”
and page 13 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 16 for cleaning
procedures.
3. Double check the unit’s ow rate and compare to
the ow rate chart for your specic UV model.
