Hozelock Bioforce revolution 12 Mode D'emploi page 6

Bioforce Revolution filters are pump-fed, pressurised
3.3
external filter and UVC units, suited to either above
ground (Fig. 7) or in-ground (Fig. 8) installation
adjacent to your pond or concealed at the top of a
waterfall.
If you choose to install your filter above ground, place
the filter on flat level ground.
If you choose to part-bury your filter, the excavation
should be firmly back-filled with compacted sand to
support the unit. If you choose this type of installation,
you should leave a minimum of a 50mm gap between
the clamp and ground level ensuring it is easily
removable for annual maintenance.
3.4 Using small bore hoses leads to excessive restriction
of the water flow. The larger the diameter of hose
that you use the better the performance of the filter
will be, especially over long hose runs. The hosetails
supplied with this unit will accommodate 25mm (1"),
32mm (1¼") and 40mm (1¾") Cypriflex hose. We would
always recommend that on the Bioforce Revolution
filters, that the 40mm diameter hose should be used to
avoid water flow restriction.
Once you have selected the hose diameter you wish
to use, cut the steps off the hosetail which are smaller
than the hose diameter to eliminate restriction (Fig. 9).
The pump which supplies the filter and the outlet of
the pond return hose should be as far apart as possible
for optimal water circulation, so bear this in mind when
purchasing, measuring and cutting the Cypriflex hose.
Attach a suitable length hose between the supply
pump and the filter inlet (Fig. 10 (i)) securing the
hose to the hosetails using Hozelock Cyprio hoseclips,
available separately. Then connect a suitable length
of hose to the filter outlet (Fig. 10 (ii)) in the same way.
For details on the waste outlet (Fig. 10 (iii)), refer to the
section "Cleaning".
Place the pump in the pond in a suitable location and
position the end of the outlet hose so that filtered
water returns to the pond.
Avoid kinks and sharp bends when positioning the
hoses. Keep the hose runs as short as possible to
minimise the restriction of flow.
3.5 Ensure the winding handle is positioned over the
electrical housing. Take the winding handle knob &
cover supplied and connect it to the cleaning handle by
locating it on the handle and clicking it in in place (Fig.
11).
Your filter is now ready for use.
Operation
4.1 Ensure the Diverter Valve is turned to the pond
outlet (Fig. 12).
4.2 Connect the filter's supply cord (See section 1 – Safety
& Electrical Connections). This switches on the UVC
lamp. You can check that the lamp is working by
looking for the blue glow in the UV lamp indicator lens
in the top housing (Fig. 1 (c)).
4.3 Switch on the pump.
Periods of Operation: Keep the filter working 24
4.4
hours a day. Ideally it should run all year round but at
least throughout the feeding season (ie until water
temperature falls below 10ºC). In winter, operating the
pump and filter will maintain a basic level of useful
bacteria in the Bioforce and will help prevent the pond
icing over. If you switch off the pump for winter, wash
the filter thoroughly before resuming filtration in the
spring (see "Winter Storage", 11.0). Never feed your fish
when the filter is not in use.
Maturation
5.1 Biological maturation means that the filter has built
up enough nitrifying bacteria to convert harmful fish
and other organic waste (ie ammonia, nitrite) into
relatively harmless nitrate. The process normally takes
6-8 weeks, but depends on many factors such as water
temperature, feeding rate and stocking density. Speed
up maturation by adding a maturing agent such as
Hozelock Cyprio Filter Start.
Cleaning
When to clean your Bioforce Revolution.
Bioforce Revolution filters deliver maximum performance with
minimum maintenance. If the pond is very dirty, the filter may
need cleaning every few days at first, as it takes up waste
matter very quickly. Once the pond becomes clearer, there
will be less waste to remove, so the filter will need cleaning
less often. Pressurised filters are at their most efficient when
the foam becomes partly blocked. However, as blockage
increases, the flow rate drops as less water can flow through
the foam and cleaning becomes necessary.
6.1 Switch off the pump at the mains.
6.2 Connect a suitable length of hose to the waste outlet
(Fig. 10(iii)) using the hosetail provided and a hoseclip.
The end of the waste hose can positioned above a
drain or over a flowerbed. The waste water makes
excellent fertiliser.
6.3 Wind the handle several times. We recommend
several revolutions in both clockwise and anticlockwise
directions (Fig. 13). As the handle is rotated, the yellow
cleaning blades (Fig. 2 (g)) will rotate breaking apart
and squeezing each foam cube releasing debris which
they have collected.
6.4 Turn the diverter valve to the waste position (Fig. 14).
You will hear a "click".
6.5 Switch on the pump.
6.6 Continue winding the handle (complete revolutions
in both directions). Initially the waste water will be
an intense green or brown colour depending on your
pond's set up.
After a short period of time the intensity of the colour
of the waste water fades and the water will start to
clear. At this point, stop winding and return the handle
to the stowage position above the main housing (Fig.
15).
Wait 5 seconds for the last bits of waste to be flushed
through and turn the diverter valve back to pond.
WARNING: Leaving the valve in the waste position
will empty the pond. Make sure it is switched back to
pond outlet.
