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

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

10 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.

Note that the following symbols may be next to the
indicator lamps on the front panel of the units and have
the following meanings:

: the power indicator

: the heater indicator

: the overtemperature indicator

6.

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.

DISMANTLED BY PROPERLY TRAINED PERSONNEL.
REMOVING THE SIDE, FRONT OR REAR PANELS
EXPOSES POTENTIALLY LETHAL MAINS VOLTAGES.

THE EQUIPMENT.
In the unlikely event that you experience any problems with
your unit which cannot easily be remedied, you should

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.
