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. On some models, the cutout is adjustable and should
be set to suit the application. On all other models 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:

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.
