require a supply rated at: 230V, 50Hz, ~,
single phase.
Power consumption is:
Model Power Model Power

THIS INSTRUMENT MUST BE EARTHED
All models are supplied with two mains leads
fitted with IEC plugs for connection to the
instrument. One has a U.K. 3 pin plug and the
other has a 2 pin “Shuko” plug for connection to
the mains. Choose the lead appropriate for your
electrical installation and discard the other.
Should neither lead be suitable, take the lead
with the U.K. plug and replace the plug with a
suitable alternative. This involves cutting off the
moulded plug, preparing the cable and
connecting to the rewireable plug in accordance
with its instructions.
IT IS IMPORTANT THAT THIS OPERATION
SHOULD ONLY BE UNDERTAKEN BY A
QUALIFIED ELECTRICIAN
NOTE: Refer to the equipment’s rating plate to
ensure that the plug and fusing are suitable for
the voltage and wattage stated.

The wires in the mains cable are coloured as
follows:
BROWN - LIVE
BLUE - NEUTRAL
GREEN/YELLOW - EARTH
The instruments are fitted with an IEC socket at
the rear of the instrument for connection of the
mains lead. The appropriate mains lead should be
connected BEFORE connection to the mains
supply.
Should the mains lead need replacement a cable
of 1mm2of harmonised code H05W-F connected
to an IEC320 plug should be used.
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
When connected to the mains electricity supply a
green light on the front panel illuminates, except
for the digital SD300 and SD500 models where
the display will illuminate showing the word
“OFF”.
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.
❖Never move or carry the unit with containers
on the top plate or while the instrument is
connected to the mains electricity supply.

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.
Heating
Models SB300, SB302, SB500, CB300, CB302,
CB500:
The knob labelled “Heat” on the front panel
controls the heat output and hence the plate
temperature.
The knob is graduated from 1 - 9. Increasing the
value increases the heat output.
Turn the hotplate control knob clockwise to the
desired setting. The amber load indicator light
will illuminate and it will begin to cycle on and
off when the desired temperature is reached and
the hotplate begins to control.
Models SD300 and SD500:
When connected to the mains electricity supply
the digital display will illuminate and show the
word OFF.

Switch the unit on by pressing the left hand one
of the 2 buttons located to the left of the digital
display. The display will now show the actual
plate temperature in degrees Celsius.
Press and hold the “press to set” button, the
right hand one of the 2 buttons located to the
left of the digital display. The display will now
show the set temperature.
The set temperature may be adjusted by turning
the knob located to the right of the digital
display whilst continuing to hold in the “press to
set” button. When the desired setting is
displayed release the “press to set” button. The
display will revert to show the actual plate
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.
