INTRODUCTION
We at Aqua Ultraviolet would like to take the time to thank you for purchasing the finest ultraviolet system on the market.
For over twenty years, Aqua Ultraviolet has manufactured ultraviolet systems which are in use in many different fields
and industries such as aquariums, aquaculture, public and commercial aquariums, educational institutions, government
agencies, commercial and research organizations throughout the world.
Aqua Ultraviolet sterilizers are used to destroy single celled organisms such as water borne bacteria, viruses and/or to
control algae and/or to kill fungi and protozoa. Aqua Ultraviolet sterilizers are recommended for both fresh and salt water
systems as well as ponds. There are no residual effects when using an Aqua Ultraviolet sterilizer. Ultraviolet will not
affect Bio-filters or lower fish immune systems!
HOW ULTRAVIOLET WORKS
The ultraviolet lamp emits a germicidal ray which alters or disrupts the DNA or RNA of targeted organisms such as algae,
bacteria and protozoa. By properly implementing an Aqua Ultraviolet system in-line, the targeted organisms can be
eradicated effectively without any harmful residuals.
The Aqua Ultraviolet sterilizer works better on filtered water. Any debris in the water can inhibit UV transmission.
CAUTION: READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION OR OPERATION.
The following instructions should answer most of the questions that you may have about the installation, operation and
use of your new Aqua Ultraviolet Sterilizer. If for some reason you should need technical support, we offer this service
for free by telephone [phone], or by fax [phone] M-F 8:00 am - 4:30 pm Pacific Standard time except
selected holidays or you may reach us through the web at www.aquaultraviolet.com.
SIZING CHART:
*As sterilizer (for crystal clear water), UV dosage is 30,000 µw/cm2 (EOL) at max flow rate.
***As clarifier, water clarity dependent on amount of sun, local temperatures, plant coverage, shallowness of pond, etc.
**Salt water gallons based on higher UV kill rate (targeting free floating parasites) and tank turnover of 3-5 times per hour.

FREQUENTLY ASKED QUESTIONS
Where do I install my UV?
The best place to install your Aqua Ultraviolet Sterilizer is after the filter. If an after the filter installation is not feasible,
your sterilizer can be installed before the filter, but it will take a little longer to work. If installed before the filter, be aware
that a small rock passing from the pump can break the quartz sleeve. It is recommended that if you install your unit
before your filter, you check the UV periodically for any water leakage due to a broken quartz sleeve. Be sure to have
adequate pre-filtration to prevent breakage. (A broken quartz sleeve and any damage caused by a broken quartz sleeve
is not covered under warranty.)
Do I have to turn my UV off when I clean my filter?
Yes, the SL Units are completely water cooled, and should not be run without water or when water is at a stand still for
any length of time. This may cause extensive, irreversible damage to the unit and is not covered under warranty.
What should I expect after my UV is installed?
If your Aqua Ultraviolet system is installed after the filter and is properly sized the water should be clear in 3-5 days. If
your Aqua Ultraviolet system is installed before the filter the water should be clear in 7-10 days. The green algae on the
sides and bottom of the pond will not disappear, this is normal in a pond. The UV doesn’t control this type of algae.
What’s the difference between a sterilizer and a clarifier?
As a sterilizer, your Aqua UV system will keep your pond or aquarium water crystal clear in addition, you will have the
added benefit of bacterial control which will help keep your fish healthy and happy with less risk of disease.
As a clarifier your pond will still have a green tint to it, unless you have 50-75% plant coverage or your pond is in full shade.
Do I install my UV vertically or horizontally?
You can install your Aqua Ultraviolet system either way. (Please see INSTALLATION INSTRUCTIONS on page 9).
What should my flow rate be on my pond or fresh water aquarium?
The optimum flow rate on your pond or fresh water aquarium is to turn over the volume of water once every hour or a
minimum of once every other hour.
What should my flow rate be on my salt water aquarium?
Your minimum flow rate should be 3 times the volume of water per hour.
Should I bypass part of my water through the UV and the rest back to the water supply?
No. Our UV was specifically designed to handle high flow rates for easier installation and the best water quality.
Is this unit submersible?
Not this specific series.
Does the UV light have any residual effect to the fish?
UV only affects what passes through the chamber. There is no residual effect from UV light.
Does the UV kill good bacteria?
Ultraviolet light does not discriminate about what it destroys. If good bacteria passes by the light it will be
destroyed. Good bacteria are colonized in your filter, along the sides and bottom of your pond. The only time it will be
affected is if it becomes free floating. All the bacteria in the filter are safe because UV has no residual.

HOUSING INSTALLATION INSTRUCTIONS
NOTE: All units are quality tested from the factory. All units are rated up to 50 PSI.
INSTALLATION SUGGESTIONS (HORIZONTAL)
SL 100, SL 200 1 lamp and SL 800-1000 Watt Units:
Plumb the water going down into the sterilizer at the
end closest to the wiper rod and up out of the end clos-
est to the transformer. This will insure the chamber stays
full of water and the wiper rod(s) does not push out.
Plumb the water going in from the bottom and out
through the top. This will insure the chamber stays
full of water and th wiper rod(s) does not push out.
INSTALLATION SUGGESTIONS (VERTICAL)
Plumb the water going in the bottom of the sterilizer and
coming out of the top. This will insure the chamber stays
full of water and the wiper rod(s) does not push out.
The above are suggestions, if you choose to install your unit in any manner other than the suggested, you must
ensure that the pump is strong enough to completely fill the chamber. If the water flow does not fill the chamber
the wiper nut may dry out causing a leak, and if left unattended the chamber will overheat and cause irrevers-
ible damage that is not covered under warranty.
CAUTION: In a vertical installation be careful not to drop the lamp down inside the unit, this can break the quartz sleeve.
The quartz sleeve is not warranted against breakage nor is any damage caused as a result of a broken quartz sleeve.
(SEE ILLUSTRATION ON PAGE 20.)
NOTE: You can use mounting brackets or plumbers straps to attach your unit to a wall or firm surface.
WARNING: Before mounting or installing your unit check the quartz sleeve(s). Do not try to install, mount or operate this
unit if the quartz sleeve(s) appears to be broken or cracked. If broken or cracked contact your dealer.
10
For all other units up
to 1000 Watts, either
port can be used as
the inlet or outlet in
a vertical installation.

1. MOUNTING: Mount your Aqua Ultraviolet system horizontally or vertically on a wall or above ground, on a
level and firm surface. Do not lay the system on the ground. Your system should be easily accessible and as
close to the filter as possible. Do not submerge. Remember to allow enough room to pull the wiper all the way
out. Below are Aqua Ultraviolets suggested installation instructions.

INSTALL UNIT WITHOUT LAMP(S) AND BALLAST. PUMP WATER THROUGH. CHECK FOR LEAKS THEN INSTALL
LAMP AND BALLAST! READ AND FOLLOW ALL INSTRUCTIONS AND/OR SAFETY INSTRUCTIONS FIRST!
CAUTION: Your Aqua Ultraviolet unit is not submersible. If this unit falls into the water, turn main power off and
then retrieve it. Do not attempt to use this sterilizer if it has been submerged. Do not operate this unit if it has a
damaged cord or plug, if it is malfunctioning or if it has been dropped or been damaged in any manner.
HINT: The UV should be installed after the filter on the return line. This ensures the water is clear of debris and impurities
that could inhibit the disinfection process. The UV can be installed before the filter, however, it will take longer to work.
NOTE: It is suggested to install a flow switch (that can be purchased through your dealer) before any SL Series UV
Sterilizer as a added protection against damage due to overheating.
Please go to our web site at
www.aquauv.com for the
“Union Install Video”.

a. Attach unions with pvc glue to the unit by cutting 2-3 1/4” pieces of pipe.
b. The inlet and outlet connection should be as close to the filter as pos-
sible on the return line.
c. Based on your personal plumbing configuration, additional plumbing
supplies may be needed.
d. Make sure the unit is mounted securely before operating. Make sure
to leave enough room to pull the wiper rod all the way out.

AQUA ULTRAVIOLET 42371 AVENIDA ALVARADO, TEMECULA, CA 92590 TEL: [phone] FAX: [phone]
If you notice a leak between the base of the
unit and the nut, the wiper nut may need
more teflon tape for a tighter seal. If the
leak persists, please contact our customer
service department for assistance.
The quartz sleeve is broken and needs
to be replaced. A broken quartz sleeve
is not, nor is any damage caused as a
result of a broken quartz sleeve, cov-
ered under warranty. Contact your dealer
for a replacement. (See INSTALLING A
REPLACEMENT QUARTZ SLEEVE on
page 19).
If you notice a leak between the wiper nut

1. COVER REMOVAL: Remove the cover from the transformer box to allow access to screw holes located on the
back panel of the box. The cover slides down.
2. MOUNTING: Mount the transformer vertically on to a wall or other vertical firm surface a minimum of 4' away from
dwelling. Make sure the transformer is close enough to attach to the UV unit.
ELECTRICAL INSTALLATION
4. DISCONNECT THE DAVIS CONNECTOR: Unscrew the Davis connec-
tor located just above the transformer cap. This will allow the transformer
cap to turn without kinking the wire.
3. CONNECT THE LAMP(S): Plug the lamp(s) into the clip connector(s)
located at the end of the individual harness(es). For 100 watt lamps connect
the red lamp wire to the black transformer wire and the black lamp wire to
the white transformer wire. For 200 watt lamps connect the red lamp wire to
the black transformer wire and the clear lamp wire to the white transformer
wire. Make sure the lamp(s) is plugged in all the way and flush with the clip
connector(s). Insert the lamp into the quartz sleeve.
NOTE: Prevent finger marks on the lamp. If you touch the lamp use dena-
tured alcohol and a soft cloth to clean the lamp.
NOTE: Lamps and quartz sleeves should be handled with care. Lamps and
quartz sleeves are not warranted against breakage and damage.
Be careful when installing the lamp. If the lamp is not plugged in all the way this may cause damage to the unit
and is not covered under warranty, nor is any other damage caused by improper installation.
In a vertical installation, do not drop the lamp into the sterilizer or it will break the lamp and or the quartz sleeve.
In a horizontal (or vertical) installation, do not install the lamp at an angle (even a slight angle); this may cause a “U”
shaped crack at the end of the quartz sleeve, or possible breakage of the lamp. If this should happen, do not proceed
with the installation. Purchase a new quartz sleeve or lamp from your dealer and refer to the proper installation instruc-
tions.
Do not force the lamp into the quartz sleeve; any force would be an indication of an improper installation.
(PLEASE SEE PAGE 20 FOR ILLUSTRATIONS).

7. FINAL LEAK CHECK: Do not plug the sterilizer into power yet, turn on pump and check for leaks again. For illus-
trations, SEE PAGE 12.
a. If there are no leaks, continue with electrical installation.
b. If you have a leak, return to INSTALLATION INSTRUCTIONS # 3 on page 11. Carefully examine this unit
after installation. This unit should not be plugged in if there are any leaks on any part of this unit.
8. GFCI CHECK: If the unit is not plugged into the GFCI (Ground Fault Circuit Interrupter) the warranty is void. A surge
suppressor should be added for extra protection, it is not needed, but recommended.
NOTE: Your Aqua Ultraviolet sterilizer has been fitted with a clear quartz cap that will glow to indicate the lamp is on.
This glow may not always be visible during daylight hours, please check at night. If the glow is not visible, please con-
tact our customer service department.
CAUTION: Do not look at or handle UV lamps when lit outside of the housing. Considerable Ultraviolet energy is emitted
which may produce severe sunburn and/or conjunctivitis with exposure to the direct UV light. As long as the UV light is
in its housing it is 100% safe to humans and fish.
NOTE: The average life expectancy of Aqua Ultraviolet lamps is 14 months, if unit is in continuous operation. After 14
months the lamp may still light, but the UV has diminished.
NOTE: We recommend that the UV sterilizer be used in continuous operation for 24 hours per day, 7 days a week.
Frequent starts and stops may shorten the life of your lamps.
SUGGESTION: If you are using any medication, we recommend shutting down the sterilizer as the UV radiation may
affect the treatment.
CAUTION: Do not use the Aqua Ultraviolet sterilizer for anything other than its intended use.
ELECTRICAL INSTALLATION CONTINUED
THIS SECTION CAN BE USED FOR NOTES:
5. CONNECT THE TRANSFORMER CAP: Twist on transformer
cap. Do not over tighten. This is a connection only and is not in
contact with water so it does not have to be tight. Do not use a pipe
wrench, pliers or any other tool.
6. RECONNECT THE DAVIS CONNECTOR: Screw the Davis connector
located just above the transformer cap back in.

CAUTION: Always unplug the unit from electricity before disconnecting or installing any parts, or before clean-
ing.
WINTER:
If you are going to continually run water through your pond during freezing temperatures be sure to take all the internal
parts inside (Quartz Sleeve, and Lamp). An optional winterized cap can be purchased from your dealer. Nema trans-
formers may be left outside.
If you are not flowing water through your system and have a winterized cap, drain the unit completely and take the inter-
nal parts inside. If the unit is not completely drained, the water will freeze and crack the housing. This is not covered
under warranty.
If you don’t have a winterized cap or you are not going to continually run water through the system, disconnect unions
and take the sterilizer inside.
Before re-installing the unit, the seals (Rubber Seal Bushing and EZ-Twist O-ring) will need to be replaced and the
quartz sleeve will need to be cleaned (see CLEANING THE QUARTZ SLEEVE on page 18). See Wiper Maintenance
Instructions on how to remove the quartz sleeve.
WARNING: Do not allow unit to be exposed to freezing temperatures, severe damage and/or breakage to the unit, bulb
