How FlowBright Work
The concept behind FlowBright is very simple. As water returning from the
filtration system passes through the assembly of your FlowBright, the high
flow/low resistance patented turbine technology extracts and converts a
percentage of the kinetic energy into electrical energy This is then utilised by
high performance LED technology to illuminate your swimming pool. The
water then flows through the directional exhaust at the bottom of the system,
helping to improve circulation.
FlowBright has been designed to have very little impact on the back pressure
in your filtration system. This is made possible by using a sophisticated gate
arrangement to divert excess water away from the turbine assembly. If use of
this gate arrangement is required, excess water flow will exit from the back of
the lighting assembly into your pool instead of passing around the turbine.
This has the added benefit of both improving pool circulation and preventing
pockets of static water from forming between the light assembly and pool
wall.

P a g e | 5
General Information
The light assembly is designed to operate when the pool filtration is active. If
the flow stops for any reason, the light will not function.
FlowBright will operate with flowrates from 6m3per hour to 10m3per hour.
Anything below this range and the system will not operate. Anything above
this range and the turbine in the housing will be rotating too fast, which may
cause damage. Water flows above 7m3per hour can be diverted away from the
turbine, using the gate arrangements –as described above. For optimal
performance and light output, please review the flowchart in this manual.
If the light assembly is fitted to a pool situated in a climate where freezing
conditions in the pool basin are common, we recommended that the light
assembly be removed, dried, and stored during the winter period if the pool is
out of use.
FlowBright is designed to screw into a standard 1.5-inch BSP female inlet
fitting. Other adaptors will be available shortly.
This version of FlowBright is recommended for residential applications and is
not necessarily suitable for commercial situations. Some small commercial
pools may be appropriate. However, this decision should be made by the pool
specialists. We are developing a commercial FlowBright.
In a low, or periodic no flow situation the FlowBright Plus is recommended.
The FlowBright Plus has an internal rechargeable battery. This will allow the
light to function at lower flows; it uses the stored battery power to illuminate
the LED array when the flow is insufficient to power the array directly.
IMPORTANT SAFTEY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS
Warning –To reduce the risk of injury, do not permit children to use this
product unless they are closely supervised at all times.

P a g e | 6
Warning –Do not attach to any suction ports such as vacuum ports. This
product is not designed to utilize water suction ports and will cause damage to
the assembly of the product, voiding the warranty.
Warning –This product is designed to only be used in conjunction with filtered
water. If unfiltered water is used to power the generator, damage will be

Flow Determination
Generally, domestic swimming pool require a combined flow rate of 6.0 –
10.0m3h and typically have between one to three return inlets. However, there
is no one way to build and design a swimming pool –differences in pipe runs,
the number of inlets, pumps sizes, etc. We have therefore taken this into
consideration when designing FlowBright. FlowBright operates on the same
6.0 –10.0m3h of flow, and if installed correctly should have no, to very little,
effect on the back pressure and flow of your filtration system. However, again,
as no two pools are alike you may need to configure your FlowBright and/or
filter return inlet configuration to achieve the best performance.
If your flow is below 6.0m3h, you have insufficient flow and will subsequently
need to alter your pool filter return inlet configuration to make your
FlowBright function –information about how to do this is below. If you have
flow above 7.0m3h then you have an excess of flow and you should use the
gate arrangements on your FlowBright. Again, the information about how to
do this is below.
A low flow battery assisted FlowBright will be available soon, designed
specifically for very low flow rates, usable when no flow is available. Suitable
for variable speed pumps.
Insufficient Flow
When multiple inlets have been adopted in your pool construction the flow to
your installation inlet may be too low for FlowBright to function optimally. It
may be necessary to reduce the flow at the other inlets, which will
subsequently increase the flow at your designated installation inlet. This can
be done by restricting the flow through the other inlets. We recommend three
ways of doing this.
If your return lines are on separate pipe runs away from the plant room.
1. Reduce the flow to the undesignated inlet by valve manipulation.
If your inlets are piped in a manifold configuration, creating a common feed
from the plant room.

P a g e | 10
2. Replace the eyeball component at your undesignated return inlet
with a trimming eyeball. This type of eyeball has a reduced
opening. Hydro-Flux Flow Trimming Eyeballs are available.
Or, alternatively
3. Replace the eyeball trim with a modified blanking off cap or
cover. To modify, simply drill a hole, no larger than 8mm,
through the front. Generally, only one hole is required; however,
more can be drilled if necessary –a maximum of three. The
number of holes needed will depend on your flow requirements.
Excess Flow
When your pool had been constructed with a large pump and few inlets have
been used, you may have excessive flow at your designated installation inlet –
flows above 7.0m3h. If this is the case, you will need to divert some of this
excess flow away from the turbine. If you do not do this, the turbine will be
rotating too fast and the pressure in your system will increase, resulting in
excess noise and wear.
Diverting the flow away from the turbine is very straightforward. Use the flow
Chart below to determine your required gate setting. To adjust the gate
arrangement on your FlowBright please follow these simple instructions.
Gates come fully closed as standard.
1. Unscrew the gate setting screw in the adaptor fixing plate.
2. Loosen the other adaptor fixing plate screws, but do not
remove.
3. Rotate the washer until you reach the correct setting. You
should see the gates in the adaptor/housing either open or
close, depending on your flow needs.
4. Reattach the gate setting screw and retighten the adaptor
fixing plate screws.

Adaptor Adjustment
The degree to which the female threaded portion of the return inlet fitting is
recessed relative to the vertical pool wall face can vary depending on the
construction of the pool. Where the threads are recessed beyond the reach of
the short adaptor, the long adaptor should be used. The long adaptor may also
be cut shorter if required. To change the adaptor, please follow the instruction
below.
1. Unscrew the adaptor fixing plate by removing both the gate
setting screw and the adaptor fixing plate screws.
2. Remove the current adaptor.
3. Replace with selected adaptor.
4. Reattach the adaptor fixing plate.
Exhaust Adjustment
When your FlowBright is installed into your pool, you might discover that the
directional exhaust is not located at the bottom of the housing. If this is the
case, you should adjust your FlowBright. (FlowBright will function at any
orientation). To adjust your FlowBright, please follow the instruction below.
1. Unscrew the adaptor fixing plate by removing both the gate
setting screw and the adaptor fixing plate screws.
2. Rotate the adaptor fixing plate and adaptor the correct number
of degrees until the exhaust is in the correct location.
3. Reattach the adaptor fixing plate screws, along with the gate
setting screw.

P a g e | 12
4. Recheck gate setting as they may have adjusted during
repositioning of adaptor fixing plate.
Maintenance
As FlowBright is constructed and installed in a simply and easy to understand
way, maintaining it is also straightforward. We recommend that you remove
the light from your inlet once every six months. Have a look over the product
to make sure that no faults have occurred, remove any potential debris from
the housing, cleaning any residue that may have formed. Once you’ve done
this, simply reattached the product.
Pool Chemistry
To keep your FlowBright functioning properly, correct pool chemistry and
water maintenance is essential. Water temperature should be not fall below
10° degrees centigrade or go beyond 40° degrees centigrade. pH should be in
the range of 7.2 –7.6, and should never fall below 7.0, as this may cause
issues with the materials used to construct the product. Alkalinity should be
between 80-120, while calcium hardness should be 200-400 at a minimum.
Chlorine needs to be no more than 2ppm. If you cannot guarantee these
conditions, please contact your pool specialist. If you do install FlowBright in
an environment that does not meet these requirements, your warranty may be
void.

Frequently Asked Questions
What happens when I backwash my pool?
The light will not function when filter flow stops at the inlet. After
backwashing the light can be switched back on if required.
Will the light operate when I’m vacuuming my pool?
The light will operate if there is adequate water flow into the light
assembly. When vacuuming through the filter, dirt will progressively
build up within the filter, reducing the water flow to the light
assembly. (Note; When the pump is turned off to adjust the multiport
valve at the filter, the flow will momentarily stop, causing the light to
turn off).
Can I use FlowBright in a salt pool?
FlowBright is constructed out of the highest quality plastics and 316L
stainless steel components. These materials generally have a high
resistance to corrosion under normal chlorinated pool water
conditions. With the addition of a salt/chlorine generator, the
aggressiveness of the water to metallic components significantly
increases; therefore, the risk of corrosion and subsequent damage
and/or failure of these components also increases. If salt/chlorine
levels are kept to a minimum, acceptable level of corrosion may occur.
If high levels or runaway levels of salt and or chlorine are present,
severe damage may occur.
