Electrical Installation

THIS EQUIPMENT MUST BE EARTHED
Before connection please ensure that the
line supply corresponds to that stated on the
rating label.
Power requirements:
Model Wattage
CB160 500W
CB161 50W
CB162 550W
CC162 550W
There is an IEC socket at the rear of the
instrument for connection to the mains supply,
(see figure 2). The unit is 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
Model Wattage
SB160 700W
SB161 50W
SB162 750W
SC162 750W
suitable alternative. See the enclosed instruction
sheet for advice on how to carry out this
procedure.
Should the mains lead require replacement a
2
cable of 1mm of harmonised code H05W-F
connected to an IEC 320 plug should be used.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN
The mains lead should be connected to the
instrument BEFORE connection to the mains
supply.
NOTE that when connected to the mains supply a
green neon light on the front of the unit
illuminates, (see figure 1).

Operation

Heating
CB160, CB162, SB160, SB162
The control knob labelled "Heat" on the front
panel controls the heat output and hence the
plate temperature. It is graduated with an
approximate temperature scale. This scale refers
to the temperature of the top plate and not to
the temperature of the contents of the vessel
being heated, When the heat is switched on an
amber pilot light illuminates, (see figure 1).
When the surface becomes too hot to touch a
red warning light on the front panel will begin to
flash, (see figure 1). This will continue to flash
while the plate temperature is above 50°C so
long as the unit remains connected to the
electricity supply.
WARNING: The top surface of the instrument
may be HOT In free air a surface temperature of
450°C can be achieved on the ceramic top
models and 325°C on the metal top models. Do
not leave heaters switched on when not in use.
Stirring
CB161, CB162, SB161, SB162
The control knob labelled "Stir" on the front
panel controls the stirrer speed. When switched
on an amber pilot light illuminates, (see figure 1).
The knob is graduated with an arbitrary 1-9 scale.
Turning the knob to a higher number increases
the stirrer speed.
