temperature and the instrument will begin to
heat.
The set temperature can be observed at any time
by pressing the "press to set" button.
Turning the adjusting knob without pressing the
"press to set" switch will have no effect on the
hotplate setting.
Models CR300 and CR302:
The knob labelled "Heat" on the front panel
controls the heat output and hence the plate
temperature. When the heat is switched on the
amber pilot light illuminates.
The knob is graduated from 1 - 9. Increasing the
value increases the heat output.
In operation only the area defined by the pattern
will become fully heated. The outer edges remain
cooler for safety considerations.
Vessels larger than the described area should not
be used. Failure to observe this could give rise to
overheating of the outer parts of the instrument.
NOTE: To prevent overheating of the
infrared heater a temperature limiter is
fitted which switches off the heater should
the temperature exceed 580°C.

Stirring
Models SB301, SB302, CB302 and CR302:
The knob labelled "Stir" on the front panel
controls the stirrer speed.
It is labelled with an arbitrary numeric scale,
1 - 9 and turning the knob to a higher setting
increases stirrer speed.
When the stirrer is switched on the amber pilot
light illuminates.

Cleaning and Care

Before attempting cleaning disconnect from the
mains electricity supply and ensure that the top is
cool.
Periodically clean the body of the instrument
using a damp cloth and mild detergent solution.
Do not use harsh or abrasive cleaning agents.
Ceramic top models: The ceramic top is very
easy to keep clean. A damp cloth will normally
remove most types of contamination. For more
difficult stains a domestic cream cleanser is
recommended. Cleaning is made easier if
spillages are attended to promptly. In any case,
spillages of alkali, phosphoric acid and
hydrofluoric acid MUST be removed immediately
as these chemicals can attack and damage the
glass ceramic. Ensure that the appropriate safety
precautions are observed.
During cleaning and general operation take care
not to scratch the surface of the top plate as this
could result in subsequent thermal breakage.
WARNING: A ceramic top which is
scratched, chipped, chemically etched or
damaged must not be used.
Metal top models: The metal top plates should
be cleaned using a damp cloth and mild
detergent solution. Do not use harsh or abrasive
cleaning agents. Cleaning is made easier if
spillages are attended to promptly. In any case,
spillages of acids and alkalis MUST be removed
immediately as these chemicals can attack and
damage the aluminium alloy. Ensure that the
appropriate safety precautions are observed.
