Safety auto shut-off
Your Sunbeam Convection Plus Heater is 
equipped with a safety system that detects 
any abnormally high temperatures within the 
heater and automatically cuts power to the 
heating element, preventing overheating. 
Once the heater has cooled it will 
automatically resume normal operation.
Thermal back-up fuse
In addition to this automatic shut-off, your 
heater contains a thermal back-up fuse to 
provide additional back-up protection. If the 
heater is in an overheat situation, the back-
up fuse will open, stopping the power flow 
to the heating element. This fuse cannot 
be reset, so in the event that the back-up 
fuse is activated, the heater will need to be 
replaced.
Instant tip-over cut-out
Your Sunbeam Convection Plus Heater is also 
equipped with an instant tip over cut-out 
switch. This switch automatically interrupts 
the power flow to the heating element when 
the heater is tilted to a certain angle. If 
the heater is tipped over, it will not turn on 
until it has been placed back in the upright 
position.
Note: The tip over cut-out switch will activate 
when the heater is tilted forward, backward 
or sideways. Care should be taken to ensure 
your heater remains upright at all times.
