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

All Techne units are supplied with a power cable. This
may be integral or plug-in.

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.

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.

indicator lamps on the front panel of the units and have
the following meanings:

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.
