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

▲ 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.
