 Use in a well ventilated area
 Ambient temperature range +5ºC to

+40ºC

 Altitude to 2000m
 Relative humidity not exceeding 80%
 Mains supply fluctuation not exceeding

10%

 Over-voltage category II IEC60364-4-443

Electrical Installation

THIS EQUIPMENT MUST BE
EARTHED

Before connection please ensure that the
line supply corresponds to that shown on
the rating plate.

Model

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).
