Supply requirements
CP300 230V, 50 or 60Hz,~, single phase
The unit is supplied with two mains leads
fitted with IEC plugs for connection to the
control box. 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.
THIS OPERATION SHOULD ONLY BE
UNDERTAKEN BY A QUALIFIED
ELECTRICIAN
The wires in the mains cable are coloured as
follows:
BROWN - LIVE
BLUE - NEUTRAL
GREEN/YELLOW - EARTH
The control unit is fitted with an IEC socket at
the rear 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 1mm
2
of harmonised code H05W-F
connected to an IEC320 plug should be
used.
NOTE: Refer to the equipment’s rating plate
to ensure that the plug and fusing are
suitable for the voltage and wattage stated.
The UK mains lead is protected by a 10A
fuse mounted in the plug top.

Safety Advice Before Use
Do not use to heat flammable materials.
Position the instrument on a firm level
surface away from any heat sensitive or
flammable material.
Never move or carry the unit while it is in
use or connected to the mains supply.
Switch off and allow to cool for at least 30
minutes.
The unit should be carried using both
hands with fingers under each side frame.
In the case of mains interruption, a fault
or failure, the unit WILL continue to
operate on removal of the fault.
NEVER immerse the hotplate unit in acid
or any other liquid. The unit has breather
holes in the base which will allow liquid
access that will destroy sensitive
components.

General Description
The acid resistant hotplate consists of a
ceramic tile and heater assembly mounted in
a block of high grade PTFE. The hotplate is
controlled via a separate control unit which is
connected by a 2 metre lead (partly covered
with a PTFE sleeve). This allows the hotplate
to be located in a fume hood and the
controller outside, away from the corrosive
environment.

Operation
1. Position the hotplate unit on a firm level
surface away from any heat sensitive or
flammable material.
2. Plug the hotplate lead into the hotplate
inlet socket of the control unit.
3. Connect the control unit to the mains
supply (the green mains indicator light will
illuminate).
4. Position the control unit in the area it is to
be used (e.g. outside the fume hood).
5. Turn the control unit ON using the
temperature control knob and select the
temperature of the hotplate by using the
printed scale around the knob. The heater
on light will illuminate.
Maintenance
WARNING: Before attempting to
clean the unit, ensure that the
hotplate is cool and that the
control unit is disconnected from the
mains electricity supply.
The control unit should be cleaned using a
damp cloth and mild detergent solution. Do
not use harsh or abrasive cleaning agents.
The hotplate body can be cleaned with
almost any cleaning agent compatible with
PTFE. A damp cloth will remove most types
of contamination. For more difficult stains a
domestic cleaner 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 the appropriate safety
precautions are observed.
NEVER immerse the hotplate unit in acid
or any other liquid. The unit has breather
holes in the base which will allow liquid
access that will destroy sensitive
components.
WARNING: A ceramic top which is
scratched, chipped, chemically etched or
damaged must not be used.

WARNING: When the hotplate surface
is hot (>50ºC) the hot warning light will
begin to flash red. This will continue to
flash while the plate temperature is above 50ºC
even after the hotplate has been switched off
(the control unit must remain connected to the
mains supply).
