Introduction
Please read all the information in this booklet before using the
unit.
Warning
HIGH TEMPERATURES ARE DANGEROUS: they can
cause serious burns to operators and ignite combustible
material.
Techne have taken great care in the design of these units to
protect operators from hazards, but users should pay attention to
the following points:
• USE CARE AND WEAR PROTECTIVE GLOVES TO
PROTECT HANDS;
• DO NOT put hot objects on or near combustible objects;
• DO NOT operate the unit close to inflammable liquids or
gases;
• DO NOT place any liquid directly in your unit;
• At all times USE COMMON SENSE.
Operator Safety
All users of Techne equipment must have available the relevant
literature needed to ensure their safety.
It is important that only suitably trained personnel operate this
equipment, in accordance with the instructions contained in this
manual and with general safety standards and procedures. If the
equipment is used in a manner not specified by Techne the
protection provided by the equipment to the user may be impaired.
All Techne units have been designed to conform to international
safety requirements and are fitted with an overtemperature
cutout. The cutout is preset to protect the unit.
If a safety problem should be encountered, switch off at the mains
socket and remove the plug from the supply.
Installation
1. All Techne units are supplied with a power cable. This may
be integral or plug-in.
2. Before connecting the mains supply, check the voltage
against the rating plate. Connect the mains cable to a suitable
plug according to the table below. Note that the unit must
be earthed to ensure proper electrical safety.

The fused plug supplied with the mains lead for use in the UK
is fitted with the following value fuse to protect the cable:
230V UK
5 AMP
The fuse in the unit protects the unit and the operator.
Note that units marked 230V on the rating plate work at 220V;
units marked 120V work at 110V. In both cases, however, the
heating rate will degrade by approximately 8%. The rating
plate is on the rear of the unit.
3. Plug the mains cable into the socket on the rear of the unit.
4. Place the unit on a suitable bench or flat workspace, or in a
fume cupboard if required, ensuring that the air inlet vents on
the underside are free from obstruction.
5. Symbols on or near the power switch of the unit have the
following meanings:
I
: mains switch On
O
: mains switch Off
After use
When you have finished heating samples, remember that
parts of the unit – the tubes, blocks and associated
accessories – may be very hot. Take the precautions
listed earlier.
