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 Operators 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 Operators 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 Operator 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. The rating plate is on the
rear of the unit. 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.
Connections 220V-240V 110V-120V
Live Brown Black
Neutral Blue White
Earth Green/yellow Green
The fused plug supplied with the mains lead for use in the UK is fitted with the following value fuse to
protect the cable: 5 AMP for TE-10A and TE-10D; 10AMP for the TU-20D.
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%.
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.
