Safety Advice Before Use
❖ If the mains supply is interrupted the units will
restart with its current settings on the
restoration of the electricity supply.
❖ Do not use an instrument with a ceramic top
if the top plate is scratched, chipped or shows
signs of chemical etching.
❖ Position the instrument on a firm level surface
away from any heat sensitive or flammable
material.
❖ Do not use the units with flammable liquids
or in a hazardous atmosphere.
❖ There is a danger of liquid spills if vessels are
stirred too vigorously. Always build stirrer
speed slowly and never stir faster than
necessary.
❖ Never move or carry the instrument until it
has been switched off and allowed to cool.

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
metal top models.
