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 Forty 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 saltwater systems as well as ponds.
There are no residual effects when using an Aqua Ultraviolet Sterilizer. Ultraviolet will not affect Biofilters 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 organisms such as algae, bacteria, and protozoa.
Properly implementing an Aqua Ultraviolet system can eradicate these organisms 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 transmission.
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 free by telephone 800-454-2725, or by fax 951-296-3490 M-THR 7:00am – 3:30 pm PST except for selected holidays.
You may reach us through the web at www.aquauv.com or info@aquauv.com.

Flow rate for all Vipers RELATIVE TO PIPE SIZE & WATTAGE

Reef Tanks: A UV rated in the 30,000 – 45,000 columns is ideal for the reef environment. UVs 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 the end of the lamp life (14 months).
WE DO NOT RECOMMEND WIPERS ON SALT WASTER APPLICATIONS

FREQUENTLY ASKED QUESTIONS

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?

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 standstill 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 freshwater aquarium is to turn over the volume of water once every hour or a minimum of once every hour and one-half hours. Please also note the minimum flow rate requirement of REFER TO CHART ASK US.

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 REFER TO CHART ASK US.

Should I bypass part of my water through the UV and the rest back to the water supply?

No. Our UVs are specifically designed to handle high flow rates for easier installation and the best water quality.

Is this unit submersible?

NO

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. 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.
