We at Aqua Ultraviolet would like to take the time to thank you for purchasing the finest ultraviolet
system on the market.
For over thirty years, Aqua Ultraviolet has manufactured ultraviolet systems used in various industries,
including aquaculture, public and commercial aquariums, educational institutions, government agencies and
research organizations throughout the world.
Aqua Ultraviolet sterilizers are used as a control to destroy single celled organisms, water borne bacteria,
viruses, algae, 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 single celled organ-
isms such as algae, bacteria and protozoa. By properly implementing an Aqua Ultraviolet system in-line, these
organisms can be eradicated effectively without any harmful residuals.
Your Aqua Ultraviolet system was made to work as a control for green water and single celled organisms. This
unit will not, nor will any other unit, completely sterilize your pond/aquarium as the pond/aquarium itself is not
a sterile environment. As a control, this unit will effectively lower your water's bacterial count allowing your fish
to stay healthier with less risk of disease.
The Aqua Ultraviolet sterilizer works better on filtered water. Any debris in the water can inhibit UV transmis-
sion.
CAUTION: READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION OR
OPERATION.
NOTE: THE QUARTZ SLEEVE MAY NEED PERIODIC CHECKING AND CLEANING DUE TO
CALCIUM AND MINERAL BUILDUP WHICH WILL INHIBIT UV TRANSMISSION.
The manual should answer most of the questions that you may have about the installation, operation and use
of your new Aqua Ultraviolet Sterilizer. View our installation videos at www.aquauv.com. If you 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. You may reach us through the web at
www.aquauv.com.

SIZING CHART
Min Flow
GPM
Minimum flow rate for all Vipers 95 GPM - 5,700 GPH
Use the clarifier column when the pond is partially in shade and has 50% plant coverage. This will improve water clarity
resulting in a natural looking water garden environment.
Use the sterilizer column for crystal clear water and bacterial control, in pond and aquarium environments.
Sterilizer numbers are based on turning the water over a minimum of 1 to 1-1/2 times per hour for optimal results.
Clarifier numbers are based on turning the water over every 2 to 3 hours.
UV dosage is calculated at the end of lamp life (14 months).
Fresh Water UV Sizing Chart
Minimum flow rate for all Vipers 95 GPM - 5,700 GPH
Reef Tanks: A UV rated in the 30,000 - 45,000 columns is ideal for the reef environment. UV's rated at higher kill
rates will destroy the planktonic food supply for the reef.
Marine Fish Tank (No Reef or Live Rock): A UV rated in the 75,000 to 90,000 columns will be the most effective at
controlling fish disease.
All UV dosages are calculated at end of lamp life (14 months).

Where do I install my UV?
The best place to install your Viper SL is after the filter and lower than the return water line. If an after the
filter installation is not feasible, your sterilizer can be installed before the filter, but consideration must be
given to the total dissolved solids in the water that may inhibit UV transmission.
Is the Flow Switch Necessary?
YES, The Viper SL Units are water cooled and the flow switch turns the Viper SL off when the flow is below
the minimum requirement of 95 GPM. The Warranty is voided if the Flow Switch is tampered with, disabled
or removed.
Do I have to turn my UV off when I clean my filter?
Yes, the Viper 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.
Do I install my UV vertically or horizontally?
The Viper SL Ultraviolet Sterilizer must be installed horizontally.
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 one and one half hours. Please also note the minimum flow rate require-
ment of 95 gallons per minute.
What should my flow rate be on my salt water aquarium?
Your minimum flow rate should be 3 to 5 times the volume of water per hour. Please also note the minimum
flow rate requirement of 95 gallons per minute.
Should I bypass part of my water through the UV and the rest back to the water supply?
No. Our UV's are 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 effects 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. Beneficial bacteria are colonized in your filter and along the sides and bottom of your pond. The
only time these will be affected is if they become free floating. All the bacteria in the filter are safe because
UV has no residual.
How often should I change my lamp?
The lamp, quartz sleeve and seals should be replaced after 14 months of continuous use.

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. As long as the UV Light is in its housing it is
100% safe for humans and fi sh.
NOTE: The average life expectancy of Aqua Ultraviolet Lamps is 14 months of continuous operation. After 14
months the lamp may still light, but the germicidal rays are diminished.
NOTE: We recommend that the UV Sterilizer be used in continuous operation 24 hours a day, 7 days a week.
Frequent Starts and Stops may shorten the life of your lamps.
WARNING: If you are medicating your fi sh, 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.
