PLEASE READ CAREFULLY
AND KEEP THESE INSTRUCTIONS
Hozelock Cyprio Bioforce filters are a new concept in fish lifesupport systems for garden ponds. They are:
•SMALLyetEFFICIENT
•EASYtoCONCEAL
•TROUBLE-FREEtoMAINTAIN
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 0.75mm2 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 Technical information section gives general guidelines on
the specifications of pump, filter and flexible hose diameter
for garden ponds up to 4500 ltrs (990 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%.
