Operator Safety - Techne CE3350 Manual Del Usuario

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 over-temperature
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.
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.

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.
