Connecting Inlet Hoses
The recommended hose size for your
Midipond filter is stated in the filter per-
formance and specification chart.
Always secure hose with a jubilee clip.
Warming the hose in a bucket of
boiling water can aid fitting.
Always ensure that the smaller
diameter hosetail is cut off and
removed to prevent reduced filter
performance.
Use the shortest possible hose lengths to minimise flow restrictions.
Avoid folds and kinks in the hose, which will reduce flow and filter performance.

Important
The outlet hoses should be smooth bore pipe installed over as short a distance as possible with no
kinks or bends.
The water level in the filter outlet chamber after the carbon wool cartridge should not be higher than
the outlet fittings when in use.
See Flow detail diagram maximum outlet chamber level. (page 9)
INSTALLATION
WARNING: If there is insufficient drop in height from the outlet pipes or excessive bends or kinks
this will cause the filter to drain poorly allowing the outlet chamber to fill above the maximum
recommended level. This will increase filter maintenance and may cause the filter to overflow.

17.562 Blagdon_Midipond filter instructions_20000/28000 AW.indd 8 17/07/2017 16:35

Connecting To Your Pump
The pump supplying the Midipond filter must not have a pumping head exceeding 6m - 0.6 Bar.
The maximum flow rate recommended is stated in the filter performance and specification chart.
This flow should not be exceeded.
The ideal flow rate for your pond is to pump the volume of the pond water through the filter every
2-4 hours. To calculate your pond volume: average length (m) x average width (m) x average depth
(m) x 1000 = Litres Pond Volume.
To calculate your pump’s flow rate, fill a container from the outlet hose of the filter at the pond side.
Time how long this takes in seconds e.g. a 10 ltr bucket takes 12 seconds to fill. Divide 3600
(the number of seconds in an hour) by the time it takes to fill the bucket e.g. 12 seconds.
Then multiply by the volume of the container. e.g. 10 ltr. Therefore - 3600 ÷ 12 = 300 seconds
300 x 10 ltr = 3000 ltrs per hour flow rate.
To increase flow you may need to get a larger pump. If flow is too high use an inline valve to
reduce it.
The purpose of the pump is to transfer dirty water from the pond to the Midipond filter.
Placing the pump at the opposite end of the pond to the filter will give the best results.
Foam-free pump designs will give optimum Midipond filtration.
UVC Bulbs & Quartz Sleeve Maintenance
The UVC lamp must be replaced yearly. It is recommended that the lamp is replaced and
reconnected in the spring.
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.
Blagdon Pond Pump Cleaner should be used in stubborn cases.
Remove the quartz sleeve from the unit and soak for 3 hours in Pump Cleaner, ensuring that all
O-rings are checked and replaced, if necessary.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC is
reconnected.
Wet Testing The Filter
INSTALLATION
IMPORTANT: A wet test of the filter under operating conditions must be carried out before the
UVC or electrical supply is installed. Connect the filter to the pump following all installation
instructions. After running for 24 hours check for leaks.

Electrical installation - UVC
The power supply must meet the specifications on the product.
The UVC is intended to be used with either a weatherproof cable connector or
permanently connected to the fixed wiring in the main system by means of a plug
and socket.
The cores in the supply cable are coloured in accordance with the following code:
Brown = Live, Blue = Neutral.
Do not use the supply cable to lift the UVC as this may cause damage.
Testing/installing the UVC lamp
1. Unscrew the UVC electronics cover cap.
2. Inspect the UVC cap and Quartz sleeve for water leaks.
3. If there are no signs of leakage reverse the procedure ensuring that the Cover o ring is in place.
If there has been any damage to the unit please return to the point of purchase for
inspection. This test should be repeated whenever the the bulb or quartz is changed.
Warning direct exposure to UVC light can damage your eyes or skin.
This unit is protected by a micro switch that prevents the UVC light from
illuminating when the cover is removed even if the power is on.
In order to check that the UVC lamp hold a piece of plain
paper up to the the UVC outlet a faint blue reflection
should be seen. This operation may be needed
to be carried out at dusk as UVC lamps emit
a dim blue light under normal operation.
INSTALLATION
ELECTRICAL INSTALLATION
IMPORTANT: Ensure that the mains supply is switched off and the power isolated before
removing the UVC cover.

Electrical/Safety
UVC Warning: Caution: Dangerous Ultra Violet Radiation. The rays from the UVC
lamp are harmful to eyes and skin. Always turn off UVC electrical supply before
any maintenance. To protect unit from flooding, leave a minimum 5cm showing
above ground level to protect UVC electrics. Never immerse unit in water.
Locate unit 1m minimum from pond edge to ensure the filter cannot fall in.
17.562 Blagdon_Midipond filter instructions_20000/28000 AW.indd 10 17/07/2017 16:35

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 special rules may exist concerning the installation of your
pond UVC (i.e. local building regulations).
This UVC must not be used in swimming pools, or areas where people are in contact with the water.
Always disconnect the mains electricity supply whilst the equipment is being installed, repaired,
maintained or handled. Consult a qualified electrician if in any doubt about wiring this product to
the mains supply.
Your Midipond filter has been designed to
need a minimum of maintenance.
When the filter system is first installed filter
cleaning may be increased for a period until
the back log of accumulated pond waste is
removed.
IMPORTANT: Please note all electrical work on garden lighting and power installations must
comply with part P of the building regulations. Failure to comply is a criminal offense. If the
installation of this product is not carried out by a competent electrician who is registered under
the Part P self-certification scheme then you must notify the local building control department
before work begins. For further information and guidance on this matter and other electrical
installations in your home that might be covered by the relevant legislation, contact your local
authorities building control department.

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 fixed wiring.

Routine Maintenance
Hydroscreen chamber
When the hydroscreen chamber fills with water and overflows into the foam chamber, remove
and wash out under a tap. It is not necessary to remove the metal screen from its carrier for
routine cleaning.
Graded foams
The filter foams only need cleaning when the foam chamber is full with water and the water layer
above the foams starts to significantly overflow the partition into the cartridge chamber.
25% of the pumps input may be allowed to overflow the partition into the cartridge chamber,
prior to cleaning.
Cleaning the foams before the foam chamber overflows will result in decreased filter efficiency
as the foams work most effectively when partially blocked.
Foams may be cleaned vigorously under a running tap or hose.
Adding Blagdon Bio Start after filter maintenance will help replenish these beneficial bacterial
populations, and is highly recommended during the first two months of operation when the filter is
slowly being colonised.
Professional ceramic bio media
These will only need very occasional cleaning (once per year), but must be rinsed in pond water to
prevent damaging the beneficial bacteria which help maintain a healthy pond.

Polymer wool and carbon cartridge
When the cartridge chamber fills with water and starts to overflow into the outlet chamber the
cartridge should be cleaned or replaced.
The Polymer wool pad may be washed a limited number of times before it starts to lose efficiency
and blocks rapidly.
The Carbon Foam pad contains activated carbon particles that remove colorants and chemical
pollutants from your pond water. After six weeks the activated carbon pad must be replaced as the
carbon becomes full with pollutants and will be unable to absorb more from the pond water.
Replacement packs of polymer wool and carbon foam pads will be available from your retailer and
are quick and easy to replace. (see diagram on page 8 and codes/descriptions on page 2)
Annual Maintenance
Check for wear
Once a year you should dismantle your Midipond filter. Dismantle the filter examining all the parts
for wear or damage, replacing any parts show obvious signs of wear or damage. (see getting to
know your Midipond filter for replacement codes and parts descriptions on page 2).
Replacing foams
After prolonged use and cleaning the filter foams will become damaged. This can be identified by
their inability to return quickly into shape after cleaning.
Replacement of the foams is recommended.
Winter Storage
The filter can be run year round if the pump flow is maintained, this is the best option. Alternatively in
winter the filter may be switched off. Follow annual maintenance procedure and store frost-free in the
house or garage until spring.

17.562 Blagdon_Midipond filter instructions_20000/28000 AW.indd 13 17/07/2017 16:35

Filter Leaks
• Check that the filter outlet nut and O ring have been correctly assembled and that they are hand tight.
• Check the hosetail connecter O ring seal is fitted and aligned correctly on the end of the hosetail
fitting and that the inlet cover is hand tight.
• PTFE tape may be needed to give a water tight seal and should be applied to the inlet or outlet
hosetails.
• Always secure the filter inlet hose and outlet hose with a jubilee clip.
• Insure that the filter is installed on a flat and level base.
Cloudy/Brown Water
• The flow rate / pond turnover is to high or to low. Check that you have correctly calculated the
pond volume and that pump flow rate is within limits. (see connecting your pump page 6)
• The filter is not being supplied with water 24 hours a day. Do not turn off your pump or UVC.
Continuous running is needed to maintain a clean and healthy pond.
• The filter foam pads are insufficiently blocked to trap the fine waste. Treat with Interpet Clear Pond
treatment.
• Do not clean the foams until the filter foam chamber starts to overflow into the carbon wool
chamber.
• The water is extremely dirty, remove pond waste and leaves - carry out a partial water change.
• Filter is incorrectly sized - refer to filter performance and specification chart. Calculate the pond
volume - see connecting to your pump page 6.
• The filter foams have not been positioned or replaced correctly,ensure that the foams fit tightly
within the filter chamber.
TROUBLESHOOTING
In order to correctly identify if you have green water or cloudy/brown water, a settlement test
should be carried out.
Take a glass of pond water and allow to settle for a few hours. When the glass is stirred a small
layer of settled waste can be seen at the base of the glass. This indicates that you have brown
or cloudy water and that if you have a UVC model it is working correctly. If there is no settlement
it indicates that you have green water and the UVC is not working correctly.
11
17.562 Blagdon_Midipond filter instructions_20000/28000 AW.indd 14 17/07/2017 16:35

Green Water
• Settlement test the water to ensure that there is no sediment suspended in the water. If there is
follow the brown cloudy water trouble shooting guide.
• At dusk check that the UVC light is illuminated by holding a piece of paper up to the UVC outlet
and looking for the reflected pale blue UVC light. Turning the lamp on and off may aid visual
identification. (Ensure the UVC lamp is not more than 6 months old).
• The UVC may be working effectively but the foams are too clean and are unable to remove the
fine coagulated waste. Treat the pond with Interpet Clear Pond and do not clean the foams until
the foam chamber starts to overflow into the carbon wool chamber.
• The flow rate of the pump exceeds the maximum flow rate that the UVC is able to handle. Check
the filter specification chart and reduce the pump flow rate if needed. It is possible to purchase a
optional flow control valve that may be fitted inline between the pump and the filter to control the
flow rate.
• The filter is too small for the pond, check the filter selection chart.
• The UVC quartz sleeve is dirty or coated in lime scale. Gently remove the quartz sleeve and clean
in Blagdon pond pump cleaner.
• Follow all cloudy water trouble shooting points.
UVC Light Not Illuminated
• Check all fuses / RCD and electrical connections follow electrical installation (pages 7-8)..
Poor flow into the filter or out of the filter
• Inspect and clean your pond pump, check that it is in good working order.
• Check foams and filter pads ,clean as per routine maintenance if blocked.
• Always use the minimum length of inlet or outlet hose needed as this will reduce back pressure
due to friction.
• Ensure that the inlet hose connecter has been cut correctly to size, if not this will restrict the flow
from the pump into the filter see diagram page 5.
• Ensure that the correct number of outlets are being used (see page 3).
• Ensure that the inlet hose is not kinked or crushed.
• Ensure that the outlet hoses are under 1m in length and that there is a drop of 15cm over this
distance, ensure that they are not kinked crushed or have a sharp bend as this will stop the filter
draining correctly.
