Overheating safety device To prevent damage and risks due to overheating, the built-in overheating safety device cuts off the power as soon as the heating elements become too hot. If this should happen: - First check if it was not the thermostat that switched the heater off by setting the thermostat control to maximum position. If the heater does not switch on again, the safety cut-out has been activated. - Remove the mains plug from the wall socket. - Let the heater cool down for 30 minutes. - Check whether you have placed the heater correctly. - Check whether something is obstructing the air flow. If necessary, clean the grilles with a vacuum cleaner. - Put the plug back into the wall socket and switch the heater on again. If the safety cut-out switches the heater off again: - Remove the mains plug from the wall socket.
