2 Safety Information
2.1 Legionella Warning
Legionella bacteria can be found in natural water sources in low concentrations. At this level it will not pose a
risk to human health, however the nature of domestic hot water storage tanks or boilers may allow the bacteria
to reproduce if the water is left stagnant for a long time.
Under normal circumstances, the frequent use of the hot water tank will protect against the growth of bacteria,
however if the tank will be left unused for a prolonged period, for example, if you are going on holiday, it is highly
recommended to ensure that any boiler controls are set to heat the water to 60°C+ at least once per week to
protect against Legionella.
2.2 General Safety Guidelines
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction regarding
the use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
The Free-E has a software generated alarm which prevents it from running when an error has occurred.
2.3 General Maintenance Guidelines
Regular maintenance of the Free-E ensures a long operating life and optimal efficiency.
The Free-E fan and ventilation grids should be cleaned periodically using a vacuum cleaner.
The following procedure should be followed;
- Disconnect the Free-e on the AC side
- Wait 5 minutes until the residual voltage has been drained and the fan is no longer turning
- Gently clean the top and bottom ventilation grids with a vacuum cleaner
Never use cleaning agents containing sand, soda, acid or chloride, as these can damage the casing of the Free-e.
The display screen should be wiped clean with a soft, dry cloth.
2.4 Electrical Safety Guidelines
When using electrical devices, there is always a risk of fire or explosion. To prevent this from occurring please
ensure that;
- The Free-E system is not placed close to any flammable materials
- The Free-E system is not placed in any areas with potential for explosion.
2.5 Legal
The construction and design of the Free-E complies with all relevant EU directives.
2.6 Intended Use
This product is designed to redistribute energy generated by a PV system to an immersion heater, that would
otherwise have been exported to the grid, and is intended for domestic and light commercial use only. Any other
use beyond that intended by the manufacturer is prohibited. This requires the user to abide by the manufacturer's
product information. Please refrain from tampering with or altering the device.

3 Free-E Overview - How it Works
When PV panels generate electricity, the production is initially consumed by electrical appliances or devices
in the household that are creating a demand for energy. If the household does not consume all of the energy
produced by the PV panels, the surplus energy will be sent to the grid.
The Free-E uses this surplus photovoltaic energy instead to heat the water in a household water tank, and
therefore prevent this energy from going to waste. The Free-E can divert up to 95% of unused (otherwise
exported) solar PV electricity to an electrical water heating device. This maximises the consumption of selfgenerated solar power and minimises the cost of buying energy for domestic hot water. It can be retrospectively
fitted to homes already with solar PV and a hot water cylinder.
