Your evoUV will keep your pond clear of green water up to its maximum capacity.
However, it is important to note that there are factors that affect how you select the
right size of evoUV for your pond.

You will need to take into consideration such things as stocking levels, sunlight /
shade, daily sunshine amounts etc. This is not always possible to calculate, and if
this is the case, use the tables below as a guide. It must be stressed however,
that these are only guidelines, and you should take advice from your local

POSITIONING AND MOUNTING THE evoUV

If installing the unit prior to or without a pond filter, we would recommend the use
of a pre-filter on the water pump to prevent excess solids from being pumped into
the unit. The evoUV may be connected to the water flow on any pumped line, this
could be, for instance, a skimmer line or any other additional pumped line. The two
most common forms of set up are pump fed and gravity fed, shown below:

Most evoUV are designed to take 1½" threaded fittings.
Note: evo110 is 2" plain fittings only.

*If your evoUV will be positioned in a permanently dry environment then it can be
installed in any position.

CONNECTION TO THE ELECTRICITY SUPPLY

Electrical installations must be done by a qualified electrician.

Do not attempt to tamper with or access the electrical control box or casing
inside the evoUV, as doing so will invalidate the warranty.

The power supply must meet the specifications on the product.
The cores in the supply cable are coloured in accordance with the following code:

Brown = Live. Blue = Neutral. Earth = Green/Yellow
(WHERE FITTED).

Do not use the supply cable to lift the evoUV as this may cause
damage.

WARNING - A Residual Current Device (RCD), also known as the
Residual Current Circuit Breaker (RCCB), with a tripping current not
exceeding 30mA must be installed in the supply circuit. A means
of disconnection from the supply having a contact separation of at
least 3mm in all poles must be incorporated in the wiring.

Caution: Use in the area of the garden pond only if the installation complies with
the relevant wiring regulations. Please consult a qualified electrician.

Caution: Always disconnect all pond appliances from the mains supply before
putting your hands into the water.

All electrical installations and wiring must be adequately protected to prevent
any damage.

Enough electrical cable is supplied with the unit to connect to the mains electric.
This unit must be connected to permanent wiring. A switch with 3mm contact
separation must be provided in the fixed wiring to provide disconnection from the
electricity supply.

UV BULB REPLACEMENT

ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLIES
BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.

TO REMOVE A UV BULB:

It is not necessary to stop the water circulating through the evoUV to change
the bulb.

1. Disconnect the electricity supply.

2. Unscrew the black end cap at one end of the unit. Take care not to unscrew the

white locking nut also.

3. Carefully slide the black end cap over the wire to reveal the bulb socket.

Take care not to lose the end cap sealing ring.

4. Disconnect the bulb socket.

5. Repeat steps 2 to 4 at the other end of the evoUV.

6. With the end caps out of the way, carefully slide out the UV bulb.

WARNING: If the end caps / electrical connections get wet during this procedure,

please ensure that they are thoroughly dried before re-connecting.

TO INSTALL A NEW UV BULB:
Follow the instructions on page 8 to fit a new UV bulb.
IMPORTANT: After checking all the fittings are correctly tightened you can switch

your unit back on.

16

As already mentioned, it is essential that the unit is protected from frost during
the winter months, or disconnected from water and electricity supplies and stored
indoors. During the spring and summer season, the quartz sleeve, which separates
the UV bulb from the water passing through the unit, will need to be cleaned two or
three times. This is essential, as dirt or limescale building up on the quartz sleeve
will inhibit the penetration of the ultraviolet light into the water and affect the
efficient working of the unit.

REPLACING / CLEANING QUARTZ SLEEVE

ALWAYS ISOLATE THE UNIT FROM ANY ELECTRICITY AND WATER SUPPLIES
BEFORE CARRYING OUT MAINTENANCE ON THE UNIT.

TO REMOVE A QUARTZ SLEEVE:
PLEASE NOTE: Removing the quartz sleeve will cause water to flow out of the unit.

1. Remove the UV bulb as described on page 16.

2. With the electricity supply disconnected, evoUV isolated and UV Bulb removed,

unscrew the locking nut at one end of the evoUV.

3. Carefully remove the quartz sleeve O-Ring and keep safe.

4. Unscrew the locking nut from the other end and remove the quartz sleeve O-Ring

and keep safe.

5. Carefully remove the quartz sleeve taking care not to allow it to drop inside the

UV body.

6. To drain any water that may be left in the unit, we would recommend that you

unscrew the mounting bracket(s), disconnect the unit from the pipework, and tilt
the unit to drain the chamber of water.

7. Clean the sleeve and polish with a soft cloth or paper towel. If you live in a hard

water area, you may get limescale on the quartz sleeve; this can be easily
removed by using vinegar or a cold water descaler.

WARNING: If the end caps / electrical connections get wet during this procedure,
please ensure that they are thoroughly dried before re-connecting.

TO RE-INSTALL A QUARTZ SLEEVE:
Follow the instructions on pages 7 and 8 to re-install the quartz sleeve and UV bulb.
IMPORTANT: After checking all the fittings are correctly tightened you can switch

your unit back on.

TROUBLESHOOTING

During this procedure or if you notice water leaking from around the end caps you
should check the following:

1. Check the O-Ring is undamaged.

2. Check there are no cracks and breaks in the quartz sleeve.

3. Check that the locking nut is compressing the O-Ring to form a water tight seal.

4. Check that the end caps are sufficiently tight.

5. All components are clean and free from dirt and debris.

*Please note that the items list 1-5 are service items and therefore not subject to a
claim under warranty. The service items listed are available from your EA stockist.

17

IN BUILT PROTECTION

The evoUV range of pond clarifiers have thermal overload protection which
automatically shuts down and then enables a fast re-start when the problem
has been cleared. This may be as a result of water in the end caps. Please see
the troubleshooting section.

Thermal Overload Protection ­This will automatically switch off the unit should the temperature exceed the
maximum operating temperature limits.

Automatic start up and shut down protection -
This protects the electrical components in the event of a power surge.

TROUBLE SHOOTING

My pond water is not clear, is this due to the evoUV not working correctly?

Koi, goldfish and other pond inhabitants can cause murky water by stirring up the
bottom of the pond. This murky water should not be confused with suspended algae.
Always check all your pond filtration is working and is being maintained correctly
prior to checking the evoUV. Mechanical filtration is necessary.

If the UV bulb is not lit, then you need to investigate the power to your unit.

• Has your RCD tripped? If yes, check your wiring and reset.

• Examine the UV bulb for signs of failure, and replace if necessary.

• Is the UV bulb fitted correctly? Unscrew the end caps and ensure correct fitting as
per the instructions as described in this manual.

• Are the end caps dry? If not, allow to dry thoroughly. We recommend the use of a
hair-dryer for this.

The unit worked well when I first installed it but recently my pond has gradually

gone green again – what is wrong?

Quartz sleeve may have become dirty and requires cleaning. Also make sure you have
the right model for your pond size. Ensure your pond filtration is removing fish waste
and debris efficiently. Dirt in ponds will affect the efficiency of the evoUV. Check that
your pond water volume is pumping through the evoUV every 2 to 3 hours.

Only after you have carried out these checks should you contact your Evolution Aqua
dealer, who will then be able to advise you further.

The unit appears to be leaking from the end fittings?

This could possibly be caused by an incorrectly fitted, damaged or overtightened
O-Ring on the quartz sleeve. Please check the quartz sleeve O-Ring, reposition it or if
necessary replace it with a new one.

FREQUENTLY ASKED QUESTIONS

How often should I change the UV bulb?

The evoUV bulb has an effective lifespan of 9000 hours, but it is an accepted
practice to replace a UV bulb once a year, at the start of every pond season.

How long after I install the unit will my pond become clear?

There are many factors which affect how long your evoUV will take to clear your
pond, such as the levels of nutrients available to the algae, the water temperature
and the level of sunlight. Assuming that you have installed the correct size unit,
most ponds should clear within 3-14 days. However, this may take up to six weeks
in some instances.

Does the evoUV harm fish, plants or wildlife?

Ultraviolet bulbs leave no residues, and only affect the water pumped through
the unit. Unlike many chemical treatments, your evoUV will not harm plants and
animals living in the main pond.

Is the evoUV suitable for salt water use?

The evoUV is manufactured from materials that will not corrode in salt water,
however the stainless steel bracket will. Use alternative mounting means when using
evoUV on saltwater systems.

Can I use my evoUV if I am using any treatments for my fish?

Always check the manufacturer’s instructions before using any water treatment as
they will tell you whether it’s recommended that the evoUV can be switched off

or on.

20

How long can I leave the unit running?

evoUVs have been designed and manufactured to the highest standards, and should
be run 24 hours a day, every day, from mid March to early October, depending on
the weather conditions. If the unit is frost protected it may be left running throughout
the winter. Otherwise, the unit should be removed, drained and stored safely for
the winter.

Can I bury the unit underground?

No. The evoUV, although weatherproof, is not suitable for installing in any situation
that may be subject to immersion in water.

Can it be used with ozone?

Yes. The evoUV is safe to use with ozone units, however, the O-Rings on the
hosetails are not. When using ozone units please use rigid pipe.

When replacing the bulb I cannot locate it into the bulb socket at the opposite end
of the evoUV?

Please follow the procedure for cleaning / replacing the quartz sleeve. This will
explain the correct procedure for removing both end caps and sockets and explain
the method for easy installation.
