INTRODUCING THE EVOLUTION AQUA EVO UV
Congratulations on purchasing an Evolution Aqua evoUV. Our range of evoUV pond clarifiers
have been manufactured using the latest technology and design techniques. evoUVs have
been designed to clear green water which is caused by single celled green algae, and
prevent it from returning. evoUVs will work alongside many different filtration systems but
when used alongside Evolution Aqua’s pond filtration systems, the evoUV will deliver crystal
clear and healthy pond water.
Please read this instruction manual carefully from start to finish before attempting to install
your evoUV.

FLOW RATES
Please note: For optimum performance we recommend that you pass the entire volume of
your pond through the evoUV unit once every 2 to 3 hours. We do not recommend the use
of pumps with operating pressures in excess of 3 bar.
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 Evolution Aqua dealer
USA - Southern States / Mediterranean 3 Watts UV per 1,000 litres
Northern Europe including UK 2 Watts UV per 1,000 litres

POSITIONING AND MOUNTING THE UV
If you are going to position your evoUV outside or in an area where it is likely to get splashed
regularly with water, then you must mount the unit the correct way up. If your evoUV will be
positioned in a permanently dry environment then it can be installed in any position.
Your evoUV must not be submerged in water or placed in a position where water may collect
around the unit. The electrics within the evoUV units are sealed in a showerproof unit. evoUV
has an IP rating of X5.
Please ensure that there is enough space at one end of the evoUV to enable bulb / quartz
sleeve removal and maintenance.
PLEASE NOTE: Wall mounting screws and wall plugs are not provided.
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:

CONNECTION TO YOUR PIPEWORK (evo15, 25, 30, 55, 75 only)
IMPORTANT: DO NOT OVERTIGHTEN FITTINGS.
The two universal hosetails supplied with the evoUV, should be screwed into the inlet /
outlet at either end of the unit. Hosetails should be tightened using hand pressure only.
Ensure that the O-Rings are in position before assembling. Please note that there is no
correct direction of flow through the unit, either end may be used as the inlet or outlet.
CONNECTION WITH FLEXIBLE HOSE
The evoUV is supplied with two universal hosetails to take ¾”, 1”, 1¼”, and 1½” diameter
flexible hose. If you are using one of the two larger sizes, the smaller sections of the hosetails
must be cut off to ensure sufficient water flow and to prevent possible damage to the pump.
We recommend that you use the largest diameter hose available. The hosetails should be
trimmed away from the unit as shown in the diagram below. Once the hosetails have been
trimmed, attach them to the unit as shown below. Secure the flexi-hose to the hosetail with
a stainless steel hose clip (not provided).

WATER TESTING THE QUARTZ, O-RINGS AND LOCKING NUTS
Now that the unit is in position and connected to pipework, the quartz sleeve and O-ring at
each end can be leak tested to ensure that they have been fitted properly. Failure to test for
leaks and improper installation at this stage may cause water to seep into and damage the
bulb socket and end cap flat washer.
STEP 1: Fit quartz sleeve, o-rings and
locking nuts.
STEP 3: Position and mount UV and
connect inlet and outlet connections.
STEP 5: Check locking nuts for signs of
water leaking.
STEP 7: If no water leaks, quartz sleeve
has been properly installed. Proceed to
connecting the UV to the power supply.
STEP 2: Check the locking nuts are
hand tight only.
STEP 4: Connect up to pipework and
turn on pump to start water flow.
STEP 6: If water seeps from locking
nuts, check quartz sleeve installation.
See Troubleshooting on page 18.
Failure to test for leaks and improper
installation at this stage may cause
water to seep into and damage
the bulb socket and ballast. Water
damage from improper installation is
NOT covered under warranty.

1. Remove the UV bulb as described on page 16.
2. With the electricity supply disconnected, UV isolated and UV Bulb removed,
unscrew the locking nut at one end of the UV.
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 8 and 16 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.

ELECTRICAL BOX REPLACEMENT
The electrical box with ballast can be easily replaced in the event of any issues.
Spare electrical boxes are available from your Evolution Aqua dealer.
Use the installation instructions provided with the spare part to install the unit.
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. Follow the steps on page 14 to test.
IMPORTANT: Do not fit the bulb socket or end cap until the issue is solved.
If water enters the bulb socket it can cause irreparable damage to bulb socket and ballast.
Damage caused by improper fitting of the quartz sleeve, o-rings and locking nuts are not
covered under warranty.
The ballast appears to have failed.
Replacement ballast boxes including ballasts, wires and lamp connectors can be purchased
as a spare part from Evolution Aqua stockists. See the evoUV spares section on our website.
