“Ultra-V”
Ultra Violet Sterilizer
by Ultralife Reef Products

Operating Principle:
The “Ultra-V” Ultra Violet Sterilizers are excellent choices for Freshwater, Saltwater and Pond applications. These units are watertight and utilize hard quartz sleeves for peak performance. The design also allows for UV Bulb replacement without the need to remove the unit from it’s installed position.
Allowing for maximum flow rates up to 1000 GPH, these units are designed to be used with your favorite water pumps.
Based on a 70,000 μW sec/cm2 (microwatt seconds per square centimeter) the flow rates are as follows:

10/ 20 Watt UV Unit 430 gph
40 /60 Watt UV Unit 1000 gph

By changing the flow rate through the UV unit you will change the active “kill power” of the UV unit.

For example: If you only allow 215 gph thru the 20 watt unit, you will effectively increase the kill power to 140,000 μW sec/cm2 (microwatt seconds per square centimeter). And also the opposite, by increasing the flow rate you will lower the “kill power”. We have included a chart to help you calculate your flow rate depending on the “kill power” needed for the corresponding Micro-Organisms.

Waterborne Algae 15,000 to 30,000 μW sec/cm2
Common Bacteria 15,000 to 30,000 μW sec/cm2
Protozoa (Ich) 45,000 μW sec/cm2
Fungi 45,000 μW sec/cm2

The “Ultra-V” is made in the USA and has a 1 year warranty on the Unit and Ballast, and 30 days on the UV Bulb and Quartz Sleeve.

Basic Installation:
1. Open UV Unit by unscrewing endcap. (End with cord coming out of it)
2. Gently slide the UV bulb into Quartz sleeve.
3. Hand tighten the fitting / grommet that seals the end of the quartz sleeve
4. Connect UV Bulb Plug from Inside the Endcap to UV Bulb
5. Install endcap back onto UV Unit..
6. Install appropriate fittings into threaded sockets on UV Unit.
7. Install hosing from pump to the UV Unit, and from UV unit to return water.
8. Install clamps on all hosing.
9. Mount UV Unit in desired location.
10. Plug UV Unit in GFCI grounded receptacle.
11. Turn on water pump with desired flow rate determined from above chart.
12. Check for any leaks. Tighten clamps if necessary.
13. If UV Bulb replacement is needed. Follow steps 1-4.
14. For Quartz sleeve cleaning or replacement follow steps 1-4, then Unscrew plastic retaining ring around quartz sleeve. Remove rubber Grommet. Slide Quartz sleeve out of unit. Clean or replace sleeve and reinstall in reverse order.
