AND KEEP THESE
INSTRUCTIONS
Hozelock Cyprio Bioforce filters are a
new concept in fish life-support
systems for garden ponds. They are:
■ SMALL yet EFFICIENT
■ EASY to CONCEAL
■ TROUBLE-FREE to MAINTAIN
And they can be sited almost
anywhere (See Fig 1).
When used with the appropriate
pond pump, the Bioforce will remove
unwanted solids from the water and
convert dissolved organic and
chemical fish waste into harmless
compounds. In addition, the
combined filter/UVC units will give
Guaranteed Clear Water if the advice
given in the Filter Equipment
Selection Chart and in these
instructions is adhered to.
SAFETY AND ELECTRICAL
CONNECTIONS
! WARNING: ALWAYS UNPLUG OR
DISCONNECT ALL APPLIANCES IN THE
POND FROM THE ELECTRICITY SUPPLY
BEFORE PUTTING YOUR HANDS IN THE
WATER WHILST EQUIPMENT IS BEING
INSTALLED, REPAIRED, MAINTAINED
OR HANDLED.
! This product is NOT SUBMERSIBLE,
and should be sited where it
cannot fall into the water or
become waterlogged. However,
the design is weatherproof, and
Bioforce filters can safely be
installed outdoors.
! Direct exposure to ultra-violet
light can damage eyes and skin.
DO NOT attempt to view the lamp
when lit, except briefly through
the viewing lens.
! This product is supplied complete
with 5m of 3 core electric cable.
For connection to the mains
supply, use only three-core cable
Ref: HO5 RN-F. This has a
minimum copper cross-section of
0.75mm
2
with Polychloroprene
Rubber Insulation. The
termination to the mains supply
should be permanent, inside a dry
weatherproof enclosure, through
a double pole switched fused spur
with a minimum contact gap of
3mm - (disconnector) to BS 3676 and fitted with a 3 or 5 amp fuse.
! Exposed cable runs should be
sensibly positioned, and protected
if necessary by armoured conduit,
especially if contact is likely with
gardening equipment such as
forks and lawnmowers, or
children or domestic animals.
! A 10mA or 30mA Residual Current
Circuit Breaker (RCD) MUST be
fitted to the mains supply.
! The supply cable cannot be
replaced. If the cable is damaged,
the unit should be discarded.
! The installation must conform to
the national and local wiring
regulations which could include
the use of plastic or metal conduit
to protect the cable.
! If in any doubt about wiring to
the mains supply, consult a
qualified electrician or your local
electricity authority.
! Protect from frost if the unit is not
to run year-round. In cold winter
weather (when fish are not active
and algal growth ceases), the unit
may be switched off. It should
then be drained of water,
removed (if possible) from its
installation and stored in a dry,
frost-protected area.
CHOOSING THE RIGHT SIZE
The Filter Equipment Selection Chart
overleaf gives general guidelines on
the specifications of pump, filter, and
flexible hose diameter for garden
ponds up to 8000 ltrs (1700 gallons).
For best results, the following
condition factors must also be taken
into account.
DEPTH
Hozelock Cyprio recommend 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 (eg South Africa), the
Condition Factor is +35%
In temperate climates (eg Southern
Europe), the Condition Factor is
+15%
In a Northern European climate (eg
most areas of Great Britain), the
Condition Factor is +0%.
EXAMPLE
You have a 2300 ltr (500 gallon)
goldfish pond 60cms (2’) 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 3400 ltrs (750 gallons).
1. INSTALLATION
1.1Important: The pump supplying
this unit must not have a
maximum head exceeding 6m (8.5
PSI, 0.6 Bar)
1.2Bioforce is a pump-fed, pressurised
external filter with integral UVC,
ideally suited to in-ground
installation adjacent to your pond
or concealed at the top of a
waterfall. They may also be
positioned above ground if
desired.
If you choose to part-bury your
Bioforce UVC filter , the
excavation should be firmly backfilled with compacted sand to
ATTENTION - UV CAUTION
Exposure to Ultra Violet (UV)
radiation can be dangerous and
cause damage to eyes and skin.
Under no circumstances should
any attempt be made to gain
access to the lamp when the unit
is switched on.
From 1st January 2005 installing this
product in the garden is classed as
'notifiable' in the revised Building
Regulations for England and Wales.
The Regulations now require you to
tell your local authority building
control department that you intend
to install this product before
installation. Your local authority will
let you know how you can get your
installation approved.
