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.

Connections 220/240V 110/120V

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:

230V UK 13 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.

Guarantee

The unit is guaranteed against any defect in material or
workmanship for the period specified on the enclosed
guarantee card. This period is from the date of purchase, and
within this period all defective parts will be replaced free of
charge provided that the defect is not the result of misuse,
accident or negligence. Servicing under this guarantee should
be obtained from the supplier.

Notwithstanding the description and specification(s) of the
units contained in the Operator’s Manual, Techne hereby
reserves the right to make such changes as it sees fit to the
units or to any component of the units.

This Manual has been prepared solely for the convenience of
Techne customers and nothing in this Instruction Book shall
be taken as a warranty, condition or representation concerning
the description, merchantability, fitness for purpose or
otherwise of the units or components.

User maintenance

NOTE THAT THIS EQUIPMENT SHOULD ONLY BE
DISMANTLED BY PROPERLY TRAINED PERSONNEL.

REMOVING THE SIDE, FRONT OR REAR PANELS
EXPOSES POTENTIALLY LETHAL MAINS VOLTAGES.

THERE ARE NO USER MAINTAINABLE PARTS WITHIN
THE EQUIPMENT.

In the unlikely event that you experience any problems with
your unit which cannot easily be remedied, you should
contact your supplier and return the unit if necessary. Please
include any details of the fault observed and remember to
return the unit in its original packing. Techne accept no
responsibility for damage to units which are not properly
packed for shipping: if in doubt, contact your supplier. See the
Decontamination Certificate supplied with your unit.

1. Cleaning

Before cleaning your unit ALWAYS disconnect from the
power supply and allow to cool below 50° C.

Your unit can be cleaned by wiping with a damp soapy
cloth. Care should be exercised to prevent water from
running inside the unit. Do not use abrasive cleaners.

2. Fuses

Your unit is protected by one or two fuses. These should
only be changed by suitably qualified personnel.

If the fuses blow persistently, a serious fault is indicated
and you may need to return the unit to your supplier for
repair.
