New From Evolution Aqua-EvoUV Ultraviolets

When the evoUVs go on sale, there will be three models making up the range. The smallest UV features a 30 watt bulb and will be known as the evo30. Next will be the evo55 model that houses a 55 watt bulb, and then completing the range is the evo110 which contains two 55 watt bulbs.

The fundamental benefits of Evolution Aqua's evoUV range is the design and build quality. They have been expertly designed using the latest technology and will be manufactured from the same polymer that is used on the tried and tested Nexus, EazyPod and Cetus sieve filters. This polymer has stood the test of time, and is renowned for forming hard wearing, long lasting units. Not only that but this polymer is UV stabilised which means it will offer a higher reflective index than a stainless steel body.

Each evoUV will feature an integrated power and bulb life indicator. This means there will be no doubt when the bulbs are working and when they will need to be replaced. The bulbs will last approximately 9,000 hours or about one year. Even if the UV is turned off the internal chip will remember how long the bulb has left to run.

The evoUV range features:

• 3 bulb sizes, 30 watt, 55 watt and 110 watt (comprising 2 x 55 watt bulbs).
• Electronic ballast
• Integrated UV bulb life indicator and power light
• UV stabilised PE outer casing which has a higher reflective index than stainless steel.
• Unique design that gives less head loss than other manufacturers’ models, saving energy costs.
• Thermal safety protection means that the unit will switch off before it overheats.
• 2" inlet and outlet on the evo110. 1.5" inlet and outlet on the evo55. Then a stepped hosetail option on the evo30.
• Unit can be mounted horizontally or vertically.

Kockney Koi Yamitsu Algea Master U.V. Ultraviolet Clarifier

Ultra Violet-UV-Yamitsu-Green Water-Algae

Yamitsu have been manufacturing Algae Masters in Great Britain since 1990. Their unique specification and design ensures a high efficiency unit at an affordable price. They are made from UV stabilised materials to ensure a longer life and incorporate turbulators to enhance the unit’s performance. Large inlet and exhaust ports make them suitable for a wide range of applications. Single tube units are available in 11, 15, 25, 30 and 55 watts. Twin units are available in 30, 50, 60, and 110 watts. It is recommended that Algae Masters should be installed using solid solvent weld pipe. However, all our units come complete with free (glue in) hosetails enabling them to be connected to ½”, ¾”, 1”,1¼” and 1½” flexible pipe. It will also fit most popular 1½”household solvent weld waste and pressure pipes.

Installation
Algae Masters can be added to any existing filtration system. For best results the unit should be fitted in line, after the pump, with water being forced through it. Use the largest size of pipe possible. If hosetails are to be used, it is very important that they are trimmed to the largest possible size that will fit inside the flexible pipe (before glueing in place). This will ensure that the maximum flow rate can be obtained for the size of pipe.

Algae Masters have been designed to run for twenty four hours a day, twelve months of the year. They should be installed in a well ventilated position but protected from frost and at no time allowed to freeze. If you are unable to position the unit in a location where it will not freeze, you should make allowances during the installation to ensure you can easily remove it for storage during the colder times of the year.

Maintenance
Although maintenance is minimal all UV lamps need replacing at six monthly intervals. The lamp may be illuminated and appear to be working but the radiation dosage diminishes with age and is ineffective after six months. Dispose of used lamps sensibly. Even exhausted lamps should NEVER be looked at directly when illuminated.

As the unit is dependant upon water passing through it, it is important to ensure that any pump strainers, pre-filters or delivery pipes are not blocked or are causing the flow to be restricted.

To change the lamp
Isolate unit from mains power, turn off pump, remove shower-proof ends and lamp holder, carefully slide out lamp, undo circular nut at each end of unit, remove “O” rings, one from each end, carefully slide out quartz sleeve. To clean use rag dampened with pond water, wipe dry with a cloth and reinstall. Use no chemical cleaners harmful to fish. To reinstate slide silica quartz sleeve back into position carefully, reposition “O” rings at either end over quartz, centralise tube with an even amount protruding at either end, replace nuts (hand tighten only), turn on pump and test for leaks, if on inspection no leaks are apparent replace lamp as above and reconnect.

WARNING

• Do not look at the lamp when on (even old or exhausted lamps)
• Do not submerge unit
• Do not run without a constant water flow (the unit is watercooled)
• Do not allow water to freeze within the unit
• Do not open while switched on
• Do not use with broken or chipped quartz sleeve

Algae Masters are guaranteed for 12 months excluding lamps and breakages
