1. SAFETY
1.1. ELECTRICAL SAFETY
WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and
any other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of
appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also
recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are
 pluggedintoasupplywhichisnotprotectedbyanRCCB.Ifinanydoubtconsultaqualiedelectrician.YoumayobtainaResidual

electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances
 andthesafetyoftheapplianceoperators.Ifinanydoubtaboutelectricalsafety,contactaqualiedelectrician.
1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1 and 1.1.2 and
use a Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections
to ensure that none are loose.
Important: Ensure that the voltage marked on the appliance matches the power supply to be
 usedandthattheplugisttedwiththecorrectfuse-seefuseratingonright.
8DO NOT pull or carry the appliance by the power cable.
8DO NOT pull the plug from the socket by the cable.

plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the
capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use of
2.5mm² section cable.

▲CARBON MONOXIDE (CO) RISKS
This heater will produce a very small amount of carbon monoxide as part of its normal operation. As carbon monoxide is a toxic gas,
particular care must be taken to provide adequate ventilation.
The result of inadequate ventilation could be fatal.
Early indications of the onset of carbon monoxide poisoning include:
 ●Headache
 ●Dizziness
 ●Burningeyesandnasalpassages
 ●Nausea
 ●Drymouthorsorethroat.
In the event of these symptoms being present, leave the area immediately and get fresh air.
 Turno󰀨theheaterandtakeoutofuseuntilserviced.
NOTE: This appliance is not intended for persons (including children) with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or instruction concerning 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.
