HEALTH AND SAFETY INFORMATION
------------------------------------------------------------------
INFORMATION FOR INSTALLER AND SERVICE ENGINEERS
Under the Consumer Protection Act 1987 and the Health and Safety at Work Act 1974, it is required to provide
information on substances hazardous to health (COSHH Regulations 1998).
Cool Energy takes every reasonable care to ensure that these products are designed and constructed to meet
these general safety requirements, provided they are properly installed and used.
To fulfil this requirement, products are comprehensively tested and examined before dispatch.
When working on the appliance, it is the responsibility of the user/engineer to ensure that any necessary personal
protective clothing or equipment is worn when appropriate for parts, which could be considered hazardous or
harmful.
This appliance may contain some of the items below:
Button Cell Battery & Printed Circuit Board
WEEE, also referred to as e-waste, is basically any waste item that has electrical components, circuitry, or a power
supply.
When WEEE is thrown away it ends up in landfills or is incinerated, resulting in valuable resources being lost
forever. Electrical items contain gold, silver, copper, and many other precious metals, which we should be doing
our utmost to keep in circulation. Retrieving them from old equipment means we can reuse them in new items
and reduce our reliance on the difficult and environmentally damaging process of mining them from the ground.
In fact, if we recovered all the copper and gold from WEEE being thrown away in Europe, we would have more
than enough for all of the new electrical equipment Europe purchases each year.
Most unwanted or broken electrical items can usually be repaired with the right tools. The more electricals we
reuse in our community, the less damage we do to the environment (and our pockets!). If reuse isn’t an option, or
items cannot be returned to the original retailer or manufacturer, WEEE can be recycled by accredited
reprocesses. Reprocesses break the items down into their component parts and recover the valuable resources
within for use in new products.
Glue, Sealants, and Paints
Glue, sealants, and paints are used in this appliance and present no known hazards when used in the manner of
which they are intended.

Section 1
Introduction
Product Overview
The Cool Energy diverTech Solar Energy Diverter is designed to harvest energy that would normally be exported to
the grid. It monitors the whole house electricity supply and when export is detected it starts to divert electricity to
a heating element in 100W increments, upto 3600w. Two elements can be connected and heated sequentially
with element 1 always taking priority. The device will also show real time data of unit status and total energy
saved.
Common FAQ’s
What can I connect to my diverTech?
The diverTech is designed for use with up to 2 immersion heaters each rated up to 3kW for water heating,
although it is possible to connect other resistive heaters like towel radiator elements.
The heating elements should always have their own thermostat controls, independent of the connection to the
diverTech unit.
How does the diverTech know when my heating element is satisfied?
When the set temperature is reached on each element the external thermostat operates to switch the element off
which the diverTech unit detects automatically. Once the first element is satisfied it automatically switches over to
heat the second (if connected). Every 20 minutes following this the diverTech will check the first elements
requirement for heat and as such treats this with priority over the second element.
When does my diverTech energy diverter start to work?
As your PV array starts to generate more power than what you are using within your property, the diverTech unit
detects this using the CT clamp. It then begins to harvest this free export energy by diverting it to the heating
elements.
What happens if I switch on other appliances whilst the diverTech is working?
Don’t worry, the diverTech will detect the change in consumption and adjust automatically.
How do I know how much energy the diverTech has saved me?
The diverTech has a built-in display, which can display savings from Today, Yesterday, Last 7 Days, Last 28 Days, &
Total Savings.
How does it work when battery storage is installed at the same property?
The diverTech units default export threshold setting is 100W. When installed with a battery system with a cut-in
below 100W no changes are normally necessary as the battery storage system would always be prioritized by
default.
What happens if I have a power cut?
Don’t worry, the diverTech will automatically restart and retain all of your settings and saved data

Section 2
Installation
The following general information describes how to install the diverTech Solar Energy Diverter.
Note: Before installing this product, read and follow all warning notices and instructions. Only a qualified /
competent person should install the diverTech solar energy diverter.
The following items are needed and are to be supplied by the installer for all inverTech installations:
1. Ensure that a suitable electrical supply cable is provided.
(2.5mm Flexible Heat Resistant Flex is recommended)
2. Connections are made inside of the heat pump electrical compartment. Conduit may be attached directly to
casing if required.
3. Local isolation must be provided in the form of a 20A double pole switch fed from a 16A MCB or a 13A fused
switch.
Mounting:
The diverTech unit should be suitably mounted to the wall using appropriate fixings.
Mounting should be at a height appropriate to allow the screen to be visible and buttons accessible.
The room where the diverTech unit is installed should be well ventilated and a minimum of a 150mm air gap
around all sides of the unit should be maintained to allow airflow for cooling.

Cool Energy diverTech Electrical Connections
Wiring Diagram
Heating elements to be connected as above.
Element 1. will always take priority, and when satisfied will automatically switch over to Element 2.
Every 20 minutes the diverTech unit will check to see if there is any demand for Element 1. and switch back to
heating this element if there is a demand present.

Installation of the Wireless CT Sender
The wireless CT transmitted box should be mounted on the wall near to the electricity meter.
The CT or Current Transformer clamp should then be installed with the arrow pointing toward the electricity
meter.
Wireless CT Sender Pairing:
To initiate pairing of the wireless CT sender to the diverTech unit follow the below steps:
1. Ensure sender unit has 2 x AA batteries installed.
2. On the inverTech unit press “Display” + “Down”buttons together for 1 second – The Screen will now
show “Pairing”
3. On the sender unit hold the middle button for 3 seconds and it will try and connect to the inverTech unit.
4. Once paring is complete “Pairing Success” will be displayed on the screen.
5. If “Pairing Failed”is displayed, please check and repeat the above process.

Timing Operation
The diverTech energy diverter can provide users with three manual boost time periods if required.
When set the maximum output will be sent to the heater outputs during this time even if there is not enough
export power.
Boost times can be set using the Up / Down buttons.
Press “Up” to enter the current setting page which displays the first time period and pressing “Up” again will move
to the next. Using the “Down” key will select the time to be adjusted and then confirm selection again with the

Commissioning
The system should only be installed and commissioned by a qualified electrician.
Whilst solar PV is generating, try and limit the household loads whilst commissioning the unit to allow some
electricity to flow back to the grid.
With the diverTech unit powered on check that it is starting to divert surplus power to the heating elements.
Then test the boost function.
If the PV array is not currently generating, you can temporarily reverse the CT clamp and turn on a household
appliance like a kettle or electric fire. This will simulate export and cause the diverTech unit to think that there is
solar surplus and start diverting power to the elements.
Don’t forget to put the CT clamp back in the correct direction afterwards!
Remember, the element outputs are sequential, and the second output won’t be triggered until the first element
is satisfied. If you wish to test the second output, it is possible to temporarily reduce the thermostat temperature
on the first element to ensure changeover. Don’t forget to correctly set the element thermostat again
afterwards!
Warning Icon
The warning icon may be displayed with the below messages:

Batteries in the Wireless CT Sender are low
– Please Replace
Lost Signal to Sender
1. Batteries in Wireless CT Sender may be flat
2. Sender too far away, signal obstruction
or interference
