cable has become damaged in any way. If the
cable is damaged, the unit should be disposed of
according to local regulations.
1.11 A 30mA maximum Residual Current Device
(RCD) MUST be fitted to the mains supply.

General Guidance
2.1 The Technical Information Chart overleaf gives
general guidance on the specifications of the
filter, recommended flow rates and flexible hose
diameter for garden ponds up to 10000 litres.
However, for best results several other condition
factors should be taken into consideration, as
these reduce the capabilities of the filter.
• Pond depth: Hozelock Cyprio recommends a
minimum depth of 1.2m (4’) for Koi ponds. For a
pond with an average depth of less than 0.75m
(2’ 6”) the Condition Factor is + 25%. Shallow
ponds are subject to full penetration of sunlight,
and warm up quickly. This encourages algae
growth.
• Location: Pond location determines the daily
amount of sunlight or shade a pond receives.
Ponds exposed to full sunshine throughout the
day have a Condition Factor of +25%.
• Climate: Climate affects water temperatures
and fish activity rate/feeding requirements. The
more active the fish, the greater the demands
on the filtration system. In hot climates (ie
South Africa), the Condition Factor is +35%.
In temperate climates (ie Southern Europe),
the Condition Factor is +15%. In a Northern
European climate (ie most areas of Great
Britain), the Condition Factor is +0%.
• EXAMPLE: You have a 2200 litre goldfish
pond 0.75m deep (Condition Factor +25%). You
live in London – a Northern European climate
(Condition Factor +0%). The pond is exposed to
full sunlight (+25%). The effective volume of your
pond is therefore increased by 50% (25% + 25%),
and you would need to size your equipment as
though your pond held 3300 litres.
2.2 Flow Rate: For best results the pond volume
should pass through the Ecopower+ every
1½ - 2½ hours, the fastest flow rate being
recommended for Koi ponds. Do not exceed the
maximum flow rate, as stated in the Technical
Information Chart overleaf. Correct flow rate is
essential if you are to obtain clear water. If your
installation does not suffer from high losses (ie
long hose runs) it may be necessary to adjust the
flow to achieve the 1½ - 2½ hours turnover rate
using a flow control hose tap.
Small diameter hose, unnecessarily long hose
runs and a high pumping lift (‘head’) can all
considerably reduce a pump’s output. We
recommend choosing a pump that will deliver
the required flow against full static lift (= vertical
distance between pond surface and filter inlet),
plus 0.6m (2ft) to allow for friction losses in
hoses.
The object of filtration is to transfer waste
material from the pond into the filter, and so
any pump used as part of the package should
be capable of handling solids such as Hozelock
Cyprio’s range of Aquaforce pumps which have
been specifically designed for ponds in the size
range covered by Ecopower+. The pump should
be positioned in the deepest part of the pond to
ensure the best circulation of water in the pond
and maximise its solids handling capability. The
pump should be installed on a flat level platform
which is raised 300mm off the bottom of the
pond. This will prevent the pump sucking dirt
directly from the bottom of the pond and will
also ensure that sufficient water remains in the
pond in the event of accidental leakage of pond
water.
How to check your flow rate: Take a container
of a known volume and time how long it takes to
fill (in seconds). Then divide 3600 by the number
of seconds it takes to fill the container, and
multiply by the volume (litres or gallons) of the
container. The result will be the flow rate in litres
or gallons per hour (lph or gph).
2.3 Fish Stocking Density: Under normal conditions
and feeding regime, the Ecopower+ range will
support up to 50cm per 1000 litres (10” of fish
per 100 gallons) of pond capacity. Introduce
