THE POND MASTERS GUIDE TO
KOI AIR
25/50/65
Congratulations on buying a Blagdon Koi Air high output pond air pump.
Koi Air pumps have been specifically designed for water garden applications.
Pond aeration is an essential part of a successful pond. Koi Air pumps are
able to run numerous air stones at one time creating a healthy oxygen rich
pond that will benefit your fish and biological filter bacteria. Your Koi Air
pump is both cost effective to run being of a low wattage design, and can be
maintained with excellent value replaceable parts.
BENEFITS OF KOI AIR POND AERATION
Fish and other pond life require oxygen-rich water in order to remain healthy. Filter
bacteria, essential to the breakdown of highly toxic ammonia and nitrite, also require
oxygen to flourish and keep the pond free from the build up of toxic waste. Use of a
Blagdon Koi Air pump will dramatically increase the level of oxygen in the pond and
reduce carbon dioxide levels, thus aiding in preventing the pond from stagnating, by
injecting air into the water. Additionally, by placing air stones directly into the filter
chambers, beneficial bacteria, essential to the well being of a pond will be
encouraged to grow. This will improve greatly filter efficiency and fish health.
Aeration in the pond is especially important in warm weather, when water holds
much less oxygen, and at night when plants stop producing oxygen and start using it
up. Fish seen gulping at the surface or swimming lethargically may be showing signs
of lack of oxygen.
In winter, use a Koi Air pump to keep areas of the pond ice-free, thus preventing the
build up of toxic gases that can be fatal to fish and other aquatic life.
Oxygenation, provided by the use of a Koi Air pump, is essential when treating fish
diseases, as many treatments deplete oxygen from the water and sick fish require
higher levels of oxygen.
IMPORTANT
Please attach proof of purchase to this manual and keep in a safe place.

6. INSTALLATION
Electrical Installation
This apparatus is fitted with a 13 amp (BS 1363) plug with a 3 amp fuse. With this or any
other type of plug an ASTA 3 amp or 5 amp fuse to BS 1362 must be fitted either in the plug
or adaptor or at the distribution board.
Replacement of Plug
IMPORTANT: This apparatus is double insulated and does not have a third
(earth) wire. The wires on the lead should therefore be connected as follows:
The blue lead should be connected to the neutral terminal on your plug. This terminal may
be marked with an N or coloured black or blue. The brown lead should be connected to the
live terminal on your plug. This terminal may be marked with an L or coloured brown or
red. Do not connect either wire to the earth terminal. If in doubt consult a qualified
electrician.
The electric cable is permanently connected and sealed in the motor body. If the supply
cable is damaged the pump must not be used.
Do not use the supply cable to lift the pump as this may cause damage.
WARNING - THIS PUMP MUST BE EARTHED
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.
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 pump (i.e. local building regulations).
These pumps 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 doubt about wiring this
product to the mains supply.
WARNING: The Koi Air pump is provided with a thermal cut out that
temporarily switches off the pump in case of overheating and the pump may
automatically restart.

7. INSTALLATION
Location
Install the pump in a dry weatherproof covered area, such as a shed or garage.
Install the pump and mains connections where they will not come into contact with water.
Ensure the pump is installed above the pond water level to avoid back siphoning of the pond
water into the air pump in the event of the power supply to the pump being cut.
Alternatively, if the air pump can only be installed below the pond level install Aqua Air
Check Valves into each piece of air line. The pump should be located on a firm surface that
will not vibrate and act as a sounding board, a concrete floor or patio slab are ideal.
Position the pump in a clean and dust free environment. Excessive dirt will block the air
filter reducing the air pumps performance and speed the wear of replaceable parts. Ensure
the pump or mains connection cannot become wet or be accidentally splashed.
Connecting the Air Line and Air Stones
Your Koi Air pump has been designed to run continuously and ideally unrestricted.
If possible, this will maintain maximum performance and the best possible life span for all
replaceable parts e.g. diaphragms, flapper valves.
Ideally all outlets should have an air line and air stones connected and used, this will give
the pond maximum aeration and ensure that damaging back pressure is kept to a minimum.
Air stones will become blocked and start to reduce the performance of the pump over time,
therefore it is necessary to replaces air stones every twelve months as a minimum or more
frequently depending on the cleanness of the air pumps environment.
IMPORTANT: If all the pump outlets or performance is not needed ensure that
one of the valve outlets is opened in order to bleed off some of the airflow,
therefore adjusting the output to the remaining air stones.
This will noticeably reduce noise levels by reducing the back pressure on the pump and
extend the life of all replaceable parts.
Connect the outlet pipe supplied and the metal valve air divider using the clips to secure.
Insert one end of each piece of air line required into the outlet nozzles of the air divider.
Place air stones onto the other end of the air line. These should then be placed into the pond
and /or filter.
Ensure that all the outlet valves are in the fully open position before the air pump is started.
Switch on the air pump. If the overall air output is to high it is recommended that one of the
air stones and air lines is removed and the remaining valves opened to reduce the air output
to the remaining air stones.
Adjustments to individual air stones can now be made. Shut off the individual valves in
small increments until the desired output is achieved.
The air stones should be positioned to provide maximum aeration and circulation in the
pond. (Note: For use in winter, air stones should be placed no lower than 30cm from the
bottom of the pond, to ensure the warmer, lower water regions remain undisturbed).

12. TROUBLESHOOTING
IMPORTANT: Before commencing any maintenance on your Koi Air pump,
ensure it is isolated from the mains electricity supply.
Low Air Output / Noisy Operation
IIs the pump on a sounding board, such as a wooden shed floor, if so place the pump on
a patio slab that will reduce the effect or relocate.
ITip, using silicone air line will help reduce noise. Ensure that no more than 15% of the
air pumps output is being restricted (see below).
IAre the air line check valves blocked or the air lines kinked.
IIf the pump is too powerful for your immediate requirements opening one of the air
divider valves without any air line will bleed off unwanted air flow and dramatically
reduce the noise, and strain on the air pump, therefore extending the life of all
replaceable parts.
IPlacing the air stones deeper in the water increases the backpressure on the pump, as it
must work harder it may become noisy. Placing the air stones at a more shallow depth is
recommended.
ICheck and replace old blocked and dirty air stones.
IReplace blocked or dirty air intake foams see section 8.
IReplace damaged or worn flapper valves see section 9.
ICheck diaphragms for wear and tear and replace if needed see sections 10 & 11.
ICheck and replace the air outlet filters in the base of the Koi Air see section 8.
IExcessive noise and wear will be caused if the pump is not in a clean and dust / dirt free
environment.
No Air Output / Pump Stopped
ICheck power supply is on.
ICheck fuses and wiring (see electrical installation).
ICheck that the metal air divider valves are opened and not fully closed.
IIf the pump is situated below the pond level and has been installed without check valves,
water may have been siphoned back into the motor.
IThe temperature sensitive thermal cutout protection circuit may have switched off the
pump to prevent permanent damage temporarily. Check ventilation is adequate and all
other points on the troubleshooting guide. Restriction or damage to internal components
of the air pump may cause overheating if not checked and resolved.
IAll flapper valves may have failed see section 9.
IBoth diaphragms may have failed see sections 10 & 11.
IIntake or outlet foams may be severely blocked see section 8.
