Safety – overheat protection
For your safety, this appliance is tted with a thermal cut-out. In the event
that the product overheats, the cut-out switches the heater off automatically.
To bring the heater back into operation, remove the cause of the overheating,
then unplug or turn off the electrical supply to the heater for a few minutes.
When the heater has cooled sufciently, re-connect and switch on the heater.
Important Notes
Although this heater is manufactured to comply with the relevant safety
standards, certain types of carpets could become discoloured by the
temperatures under a portable heater. If you are concerned about this,
we recommend that you contact the carpet manufacturer for guidance.
Alternatively, either stand the heater on a suitable base to shield the carpet
– call our Helpline for further advice.
You may notice some parts of the element appearing to be hotter from time
to time because of the variable airow through the heater. This does not
cause a safety hazard.
The heat outlet grille may become discoloured with use – this is caused by
airborne pollution and is not a fault.
