For permanent installations to the mains supply, it is necessary to conform to the regulations of the
local electricity authority and this would include the use of a metal or plastic conduit to protect
the cable.
Attention has been drawn to the fact that the special rules may exist concerning the installation of
your pond filter (i.e. local building regulations). These filters must not be used in swimming pools,
or areas where people are in contact with the water.
Always disconnect and isolate the product from the mains electricity supply whilst the equipment
is being installed, repaired, maintained or handled. Consult a qualified electrician if you are in
any doubt about wiring this product to the mains supply.
Important: This appliance can be used by children aged 8 and
above and persons with reduced physical, sensory or mental

Location of the filter
The Blagdon Clean Pond Machine should be located on a firm and level base on the ground,
at least 1.2m (4’) from the pond. The filter can be buried up to the bottom rim of the head unit,
leaving just the UVC access, inlets & outlets, and cleaning handle exposed about the ground level.
Ensure the filter outlet is at no more than a maximum of 4m head height above the lid of the filter.
INSTALLATION
3x multi hose tails, (inlet,
outlet & waste) to fit the
following hose diameters:

INSTALLATION
Connecting to your pump
The ideal flow rate for your pond is to pump the volume of the pond water through the filter
every 2 hours. To calculate your pond volume: average length (m) x average width (m) x
average depth (m) x 1000 = pond volume in Litres.
To calculate your pump’s flow rate, fill a container from the filter outlet hose at the pond
side. Time how long this takes in seconds, e.g. a 10 Litre bucket takes 12 seconds to fill.
Divide 3600 (the number of seconds in an hour) by the time taken to fill the bucket,
e.g. 12 seconds. Then multiply by the volume of the container, e.g. 10 Litres.
Therefore: 3600/12 = 300, 300 x 10 = 3000L/H flow rate.
To increase flow, you may require a larger pump. If the flow rate is too high, use an inline valve
to reduce it (or use the digital control of a Blagdon Amphibious IQ pump).
The purpose of the pump is to transfer dirty water from the pond to the filter cannister.
Placing the pump at the opposite end to the filter outlet will provide the best results.
Pumps without foam pre-filters will allow for optimum filter performance.
Connecting the inlet/outlet hoses
•Always secure the hose with a jubilee clip.
•Warming the hose in a bucket of warm water can aid fitting.
•Always ensure the smaller diameter hose tails are cut off and removed to prevent
poor UVC performance and flow rate from the outlet.
•Use the shortest possible lengths of hose, in order to minimise flow restrictions.
•Avoid folds and kinks in the hose, which will reduce flow and UVC performance.

IMPORTANT:
The outlet hose should be
smooth bore (not corrugated)
pipe installed over as short a
distance as possible, with no
kinks or bends. We recommend
that a smooth bore clear hose,
or smooth bore heavy duty
black hose are used.
7
IMPORTANT: Do not exceed the maximum stated flow rate through the UVC filter –
see technical specifications table on page 4 for reference.

UVC bulbs & quartz sleeve maintenance
The UVC bulb must be replaced yearly – it is recommended that the bulb is replaced in
the spring or early summer, in order to provide the maximum performance during the most
problematic period of the year for green water.
The quartz sleeve can become coated in lime scale build up in hard water areas.
This should be carefully removed from the quartz sleeve with a soft cloth.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC
is reconnected.
1. Undo the four screws on the UVC electronics cover cap
2. Unscrew the UVC electronics cover cap.
3. Inspect the UVC cap and quartz sleeve for water leaks.
4. If there are no signs of leakage reverse the procedure ensuring that the cover O-ring is in place.
INSTALLATION
IMPORTANT:
A wet test of the filter under operating conditions must be carried
out before the UVC or power supply are installed.
Connect the filter to the pump following all installation instructions,
check for leaks after 24 hours.
8
The unit is protected by a micro-switch, which prevents the UVC light from illuminating when the
cover is removed.
In order to check that the UVC lamp is operating correctly, check the indicator window above
the cable inlet gland on the UVC electronics cover cap whilst the UVC is installed into the filter.
This operation is best carried out at dusk, as UVC lamps emit a dim blue light which can be
difficult to see in daylight.

INSTALLATION
Testing/replacing the UVC lamp
IMPORTANT:
Ensure the mains power supply is switched off and the power isolated
before removing the UVC cover.
1. Undo the four screws on the UVC electronics cover cap
2. Pull out the UVC electronics cover cap.
3. Unscrew the Quartz sleeve lock nut.
4. Remove the old bulb, and replace for new.
5. Complete steps 1-4 in the reverse order to reconstruct the unit – ensuring all O-rings
are correctly positioned.
IMPORTANT:
If there has been any damage to the unit, please return to the point of purchase for inspection.
This check should be performed whenever the UVC bulb or quartz sleeve is changed.
WARNING:
Dangerous Ultra Violet radiation. The rays from the UVC lamp are harmful to eyes
and skin. ALWAYS turn off the UVC electrical supply before any maintenance.

MAINTENANCE & CLEANING
Your Blagdon Clean Pond Machine has been designed to need a minimum of maintenance.
It will work at it’s best with some simple, monthly routine maintenance.
If the filter is installed on an established pond, the regularity of cleaning may be increased
for a period until any back log of accumulated pond waste has been removed.
Normal Running
For excellent filtration, the filter should be
operated 24 hours a day, all year round.
1. Check that all seals and
connections are not leaking.
2. Ensure the valve is turned to the outlet
returning to your pond or waterfall.
Routine Maintenance
Once established, it is recommended that
your filter should be backwashed and
cleaned once a month.
It may require more frequent cleaning when:
•The flow has visibly reduced.
•The water in the pond appears dirty.
NOTE: The cleaning procedure uses water pumped from the pond, meaning during cleaning
the water level in your pond will drop. After cleaning you should refill the pond using water
which has been dechlorinated with a product such as Blagdon ‘Clean Pond Pods’ or
Blagdon ‘Fresh Start’.
10
IMPORTANT: If the filter has not been cleaned for more than a month, or if the flow rate
from the outlet has dropped by 50% or more - after turning the flow diverter valve to
waste, turn the pump off before attempting to turn the cleaning handle.
After one full rotation the pump can be turned back on to flush out the waste released,
and the filter can be cleaned as per the usual instructions.

To clean your Blagdon Clean Pond Machine, follow these simple steps:
NOTE: A maximum of 10 Clean Pond Pods can be fitted into the dosing chamber at any one
time, this is sufficient for a pond with a volume of 5000L. If a higher amount is needed, the
dose should be split in half and dosed over subsequent days to allow the pods time to dissolve.
If Clean Pond Pods are being dosed at the same time as a filter clean, return the flow back
to the pond before closing the dosing chamber lid – else the action of cleaning will wash the
contents of the pod away as waste.
NOTE: If you are not dosing Clean Pond Pods or you are cleaning the filter as part of a
water change you do not need to remove the dosing chamber cap, simply return the flow
diverter valve back to the filter outlet once the water runs clear or you have drained the
desired amount of water from the pond.

Annual Maintenance
Check for wear
Once a year it is recommended to dismantle your Blagdon Clean Pond Machine and examine
the parts for wear or damage – replacing parts showing any signs of wear or damage.
Replacing filter media
Due to the material and method used in cleaning the filter media contained in the Blagdon Clean
Pond Machine, it should never need replacing, as even if it is clogged solid, and unable to be
cleaned using the handle, it is possible to clean it by removing it from the filter into a bucket of
water taken from the pond.
IMPORTANT:
If the head unit is removed, keep it upright. This will prevent any of the filtration media stuck on
the cleaning blades and plate from falling and getting stuck in the cleaning mechanism.
When returning the head unit to the filter be sure to carefully remove some water from the
cannister to lower the level of the media below that of the central downpipe – retrieve any
media which has entered this pipe and return it to the main filter body.
Winter Storage
The filter can be run year round as long as the pump flow is maintained, this is the best option.
Alternatively, in winter, the filter can be switched off. If the filter is to be switched off during the
winter it should be fully drained of water prior to being stored in a frost-free location, such as a
shed or garage, until spring.

Annual Maintenance
Disassembling/reassembling your Clean Pond Machine
We would recommend to clean the bottom grill annually
to maintain the performance of the filter, to clean this the
following instructions should be followed:
1. Turn off the pump.
2. Undo and remove the lid clasp,
lift off the filter head unit.
3. Carefully remove all of the CHI media
to a clean bucket and drain the filter
cannister of water.
4. Unscrew the central locking nut and
remove the downpipe.
5. Lift the bottom grill out from the
bottom of the filter and rinse in
clean, fresh water.
6. Return the grill to its position
in the bottom of the cannister
(note the locating notches and fins),
reinstall the downpipe and locking
nut to lock it in position.
7. Cover the hole of the downpipe
and carefully return the CHI media
to the filter cannister, once it’s all
in uncover the downpipe.
8. Reinstall the filter head unit and lid clasp
– reattach any hosetails and turn the
pump back on. (ensure the flow diverter
valve is initially positioned to waste to flush
out any fish waste which has been
dislodged from the media in the process.)

TROUBLESHOOTING
Filter Leaks
•Check that the inlet and outlet nuts and O-rings have been correctly assembled and that
they are hand tight.
•PTFE tape may be needed to give a water tight seal, and should be applied to the thread
of the inlet and outlet hose tails.
•Ensure the filter head gasket is in the correct position, and is free from any detritus.
•Ensure that the hoses are secured to the inlet and outlet hose tails with a Jubilee Clip.
•Ensure that the filter is installed on a flat level base.
Cloudy/Brown Water
•Check that you have correctly calculated the pond volume, pond depth and the ponds level
of direct sunlight. Check this information against the pond sizing table on page 4. You may
require a larger Clean Pond Machine model.
•Adding shade to the pond by introducing lilies or floating plants to the water surface will help
to reduce pond sludge. Planting the pond with marginal plants will also help create a
balance. New ponds may require some time to establish and create a healthy balance.
•The filter is not being supplied with water 24 hours a day. Do not turn off the pump feeding
the filter with water – continuous running is required for the beneficial bacteria within the filter
to break down fish waste.
•The filter media is insufficiently blocked – allow the Clean Pond Machine media time to clog,
as the media clogs it will trap finer and finer waste.
•The water is extremely dirty – physically remove pond waste and leaves, carry out a partial
water change.
UVC Leaks
•Check that the UVC O-rings are all in the correct position.
•Check for damage to the Quartz sleeve.
•Ensure the UVC electronics cap is tightened sufficiently to make the watertight seal.
Low/No flow from filter
•Check that the pump is running. Check the mains power supply.
•Ensure all pipework is fully connected to the pump and filter.
•Check for blockages in the pipework.
•Clean the filter – the Clean Pond Machine media may have become too blocked by
pond waste.
14

Green Water
•Perform a settlement test to ensure that the is no sediment suspended in the water – if there is
follow the brown/cloudy water troubleshooting guide.
TROUBLESHOOTING
PERFORMING A SETTLEMENT TEST:
Take a glass of water from the pond and allow to settle for a few hours. If when the glass
is stirred a small layer of settled waste can be seen at the base. This indicates that you
have brown/cloudy water and that, if you have a UVC, it is working correctly. If there is no
settlement it indicates that you have green water and that the UVC is not working correctly.
•At dusk check the UVC light is illuminated using the viewing window on the UVC electronics cap.
UVC illumination
viewing window
•Check the age of the UVC bulb. As UVC bulbs age the light output deteriorates, if the bulb
is over 6 months old, the output may not be strong enough to have an effect on the algae
causing green water – change the bulb.
•The UVC may be working effectively, but the filter media is too clean so is unable to remove
the fine coagulated waste – treat the pond with a clearing product, such as Blagdon Clear
Pond, this will clump the particles together to make them larger, and therefore easier to
remove from the water passing through the filter.
