Hot Surfaces

WARNING: The top surface of the
instrument may be HOT. Do not leave
heaters switched on when not in use.
WARNING: When the surface becomes
too hot to touch the red "HOT" warning
light on the front panel will begin to flash.
This will continue to flash while the plate
temperature is above 50°C even if the unit
is switched off as long as it is connected
to the electricity supply.
WARNING: Do not disconnect or switch
off the electricity supply until the "HOT"
warning light has ceased flashing.
WARNING: The plate may still be hot
when large masses are left on the plate,
even though the "HOT" warning light has
gone out.
WARNING: The top surface of the
instrument may be HOT, especially in free
air when a surface temperature of up to
450°C can be achieved on some of the
ceramic top models and 300°C on the
