Please Ensure: The power supply must be earthed and fused at 3amps.
Regularly inspect the cable for damage and deterioration. Consult a qualified
electrician if in doubt about any aspects of wiring.

Please read the below instructions carefully before beginning to set up your UV
steriliser system. DO NOT CONNECT THE UNIT TO THE MAINS UNTIL SET UP IS
COMPLETE.
1. Prior to installing the unit, examine the quartz sleeve and UV bulb to make
sure these have not been damaged in transportation (see maintenance section).
Handle with care. Do not hold UV bulb with bare hands as this can affect
performance.
2. Assemble your CUV unit as per the diagrams in the “Parts Diagram” section.
PLEASE NOTE: unlike other sterilisers, CUV units (excluding CUV-207 and CUV-
272) come with one inlet and two outlets - very useful if you want to run the
output to a two-fall waterfall, or indeed a waterfall and a filter. The steriliser is
also supplied with a separate glass viewport which can be used to replace one
of the hosetails for use as a one-in / one-out unit.
INSTALLATION & USE
3. Add fixing brackets to your unit (CUV-211 model only). There should be one
at each end of the unit. You can then use them to secure the unit on flat surface.
PLEASE NOTE: CUV-207 / 209 / 218 / 224 / 236 / 272 models come with
preattached fixing brackets.
3. Clear hosetail - is interchangeable with the black hosetail. It has a spindle
that indicates the flow rate so you can use it on the inlet/outlet. Sometimes
you may notice the spindle stops rotating, this is
okay as long as the water runs through the unit.
4. Make sure the O-rings are placed smooth side up
to the hosetail (see image on the right for reference).
This will prevent leakage.

5. Pond installation - place your CUV unit at least 2 metres away from pond.
This is to ensure the UV unit cannot fall into the pond. Connect pipework from
feeder pump (not included) to inlet hosetail and secure using clip/clamp.
Connect pipework to hosetail outlet to feed into filtration system (not included)
or return water to pond to ensure this is water tight.
6. Aquarium installation - place your CUV unit securely on a flat surface.
Connect outlet pipework from aquarium pump or external filter to CUV inlet
hosetail.
Connect pipework to hosetail outlet to return water to aquarium. Secure all
pipework using hose clip/clamp to ensure this is water tight..
5. Connect your CUV to the mains - connect the unit to the mains using a
residual current device (RCD) for additional safety.
6. Switch on your unit at the mains - turn on the operation by switching on the
unit at the mains.

UVC OPERATION
· Always ensure that the filter has water flowing through the unit prior to
operating the UV.
· Never look directly at the UV light when operational.
· Check that the UV is operational visually using the UV indicator.
· Never operate the UV lamp outside its housing.
· Never operate the UV lamp in a housing that’s defective.
MAINTENANCE
To ensure optimal performance and that your unit functions correctly, regular
maintenance is essential. Failure to do so may result in damage to your unit and
may invalidate your warranty.
We recommend that a regular cleaning and maintenance schedule is followed
to ensure responsible fishkeeping. Depending on water volume and stocking
levels, regular cleaning of the quartz sleeve and inlet/outlet pipework will help
ensure that the product works efficiently and your pond remains healthy.

General Maintenance
It is recommended that every 2-3 months you perform maintenance on your
CUV unit. This is necessary to prevent blockage and inspect the bulb and
quartz sleeve. Make sure to inspect the unit’s cable for damage or excessive
wear.
IMPORTANT! Disconnect mains electricity supply before handling or
attempting maintenance.
Quartz sleeve & UV bulb - to access UV bulb unfasten the clip located on the
side (CUV-207 / 209 and 211 models only) or using a coin push down the clear
plastic button on top of the ballast (CUV-218 / 224 / 236 / 272 models only).
Gently turn the ballast counter clockwise and pull the ballast apart from the UV
case.
CUV-207 / 209 / 211
CUV-218 / 224 / 236 / 272
NOTE: be very careful when removing the ballast as the UV bulb and UV
quartz are very fragile.

The quartz sleeve can be coated in limescale build up in hard water areas.
This should be carefully removed from the quartz sleeve and cleaned with a
soft damp cloth.
Use a flathead screwdriver to separate the quartz glass from the UV case
and remove the quartz by pulling it out (CUV-207 / 209 and 211 models only).
Unscrew the clamp screw and gently remove the UV quartz from the ballast
(CUV-218 / 224 / 236 and 272 models only).
Clean body and all attachments. Reassemble.
CUV-218 / 224 / 236 / 272CUV-207 / 209 / 211
IMPORTANT! When reassembling your unit you must replace all O-rings as
per the parts diagram as otherwise this can cause the unit to leak which will
cause permanent damage to the UV operation.
Common Reassembly Questions
CUV-207 / 209 / 211 - when reassembling your unit you must make sure the
black O-ring sits on top of the quartz sleeve as seen in the image below.
Close the unit with the ballast pointing downwards. This is to ensure the O-
ring doesn’t fall out of place and enables you to correctly close the unit.

Replacing the UV Bulb
NEVER look directly at the UV light.
When replacing your UV bulb, use this time to clean your quartz sleeve and
carefully examine for any damage or cracks. Take care when handling the
quartz sleeve and UV bulb to avoid any damage to the glass.
1. To access UV bulb unfasten the clip located on the side (CUV-207 / 209 and
211 models only) or using a coin push down the
clear plastic button on top of the ballast (CUV-218 /
224 / 236 / 272 models only). Gently turn the ballast
counter clockwise and pull the ballast apart from
the UV case.
IMPORTANT! The replacement does not require
removal of the gold outer shell protecting the
bulb (CUV-207 / 209 and 211 models only).
The top of the gold outer shell has sharp edge, DO
NOT touch this part.
2. Once cooled, UV bulb can be safely removed by
gently moving it from side to side (CUV-207 / 209 /
211) and pulling free of unit.
3. You can now replace your UV bulb and
reassemble the unit. Ensure O-rings are
replaced when reassembling to avoid water
ingress.
CUV-218 / 224 / 236 / 272 - when taking your
quartz sleeve out, you might notice the orange O-
ring falls out into the ballast part of the unit. When
reassembling your unit make to replce it as seen in
the image on the right. This is to enable you to
correctly close the unit.

IMPORTANT! Check regularly that your UV light is operational by looking at
the UV light indicator.
Always change your UV bulb every twelve months regardless of it working or
not, as its performance will lessen by this stage. We recommend to replace
your bulb every 6 months if used for aquarium and 12 months if used for
pond.

If the UV indicator located on the top of the filter
casing (CUV-211 / 218 / 224 / 236 & 272) or side of
the unit (CUV-209) is not lighting up follow these
troubleshooting steps:
1. Clean the UV indicator.

2. Please check for signs of damage or water
ingress to quartz sleeve and bulb area. You might
need to replace your quartz sleeve, ballast and/or
O-Rings if that’s the case. Ensure that all O-rings
are in place and well lubricated.
3. If you find that the UV light is still not
operational, check that you have power from the
mains supply.
4. If you do have power from the mains
supply, check if you can see the UV is
operational through the viewing hole. If you aren’t
able to see it, try performing a safety override.
Locate the safety override switch on the ballast
end next to the UV bulb fitting (as shown in the
images on the right).
IMPORTANT! NEVER look directly at the UV light.
Press and hold the small thin silver switch
when the power is on and the bulb should
ignite. Please test in a dark/ shadowed
place and do not look directly at the bulb –

UVC Leaks
If your unit is leaking follow these troubleshooting steps:
1. Check that the UVC inlet/outlet caps and O-ring have been correctly
assembled and that they are hand tight. Ensure the O-rings are intact, well
lubricated and not twisted or damaged.
2. Always secure the UVC inlet hose and outlet hose with a jubilee clip.
3. If you find that the unit is still leaking after the above checks or there is an
obvious casing crack, you will need to replace the body casing on the unit.
we recommend covering the bulb with kitchen roll or similar. You should still
be able to see the glow of the bulb through this.
5. If the above does not solve the issue replace the UV bulb.
6. If you find that the UV light is still not operational after the bulb
replacement, the UV ballast may have developed a fault and you will need
to contact the supplier of your unit to obtain replacement parts.
Please remember that UV bulbs for use in ponds should be replaced every
12 months.

The UV Bulb is on But My Pond is Green
There are a lot of different factors which contribute to this type of issue and it
may not be the UV system at fault. The steriliser will work to maintain rather
than transform water quality so you may need to add treatments to clear poor
quality water or consider a heavy water change. If the UV light is working then
the product is functioning correctly.
Algae growth in water can be due to high phosphate and nitrate and green
water is heightened in the summer period due to the extra sunlight so it is also
advised that a water test is carried out.
1. Pond Position - The position of the pond should also be considered, as this
affects how much sunlight is directly falling on the pond. Algae growth is very
likely to require a treatment to resolve the growth. Consider purchasing the All
Pond Solutions Green Water treatment or Blanketweed treatment.
The orientation of the garden can also be an issue; south facing gardens
inevitably get more sunlight and can cause ponds to be greener in the
summer if exposed all day. Try and shade your pond water surface, floating
pond plants such as Lilies are a great way to do this.
2. Pump’s Flow Rate - the flow rate of the pump exceeds the maximum flow
rate that the UVC is able to handle. Check your unit’s specifications and reduce
the pump flow rate if needed.
3. Filter - the pond filter works with the UV steriliser to keep the water clear by
removing the dead algae. Check if your filter size is adequate to your pond size.
4. Quartz Sleeve - check if your quartz sleeve is dirty or coated in limescale.
Gently remove the quartz sleeve and clean it.
In order to correctly identify if you have green water or cloudy/brown water, a
settlement test should be carried out.
Take a jar of pond water and allow to settle for 24 hours.
Green Tinge - If your jar is showing mostly green tinged water or has green
particles floating in it, you most likely have a bit of an algae problem (follow
the green water trouble shooting guide).
Brown Tinge / Water with Sediments - this indicates that you have organic
debris decomposing in your pond. This can be particles from dead leaves,
twigs and other plant debris that are breaking down (follow the brown water
trouble shooting guide).
Green Water or Cloudy/Brown Water?

If none of the above resolves your issue, or you require spare parts for your
filter, please contact the supplier of your unit.
SPECIFICATIONS
My Pond Water is Cloudy/Brown
1. Make sure the unit is turned on 24 hours a day. Continuous running is
needed to maintain a clean and healthy pond.
2. Remove pond waste and leaves and carry out a partial water change. If
sludge is present treat your pond with All Pond Solutions Anti Sludge
treatment.
3. Reduce feeding. Overfeeding introduces a lot of organic waste and is one of
the main causes for cloudy water problems.
4. Make sure to perform regular water changes, check your unit is clean and
adequate for your pond size and do not overstock it.

Blanketweed attaches itself to the walls, plant and
rocks within your pond and is sometimes known to
float on the water’s surface, this can prevent to
blanketweed from being pulled through the filter
and UV resulting in the algae not being treated.
In order to treat blanketweed use All Pond
Solutions Blanketweed treatment. This will bind to
the blanketweed and break it down. It will then
allow the filter to pull the remaining algae through the UV system eradicating
any spore the blanketweed may release, and finally filter it out.
