General Information

Section 1 Introduction and Unpacking

Your satisfaction and safety are important to Thermo and a complete

understanding of this unit is necessary to attain these objectives.

As the user of this apparatus, you have the responsibility to understand the

proper function and operational characteristics of your bath. This

operating manual should be thoroughly read and all operators given

adequate training before attempting to place this unit in service.

Awareness of the stated cautions and warnings, and compliance with

recommended operating parameters — together with maintenance

requirements — are important for safe and satisfactory operation. The

unit should be used as described and for its intended application;

alterations or modifications will VOID THE WARRANTY.

Warning As a routine laboratory precaution, always wear safety glasses

when working with this apparatus.

This product is not intended, nor can it be used, as a sterile or patient

connected device. In addition, this apparatus is not designed for use in

Class I, II or III locations as defined by the National Electrical Code. s

Caution When unpacking this product, two persons are required to lift the

water bath and place it on a bench.

The bench top must be rigid and strong enough to comfortably support

the weight of the unit when filled with water. s

Precision Circulating Baths are widely used in research and quality control.

Their superb temperature uniformity and stability makes them especially

desirable for legal or reference tests.

The microprocessor control panel houses all functions necessary to operate

the bath. The 4 push-button switches and single digital display window

allow the operator to adjust bath temperature and temperature calibration

via a single set of controls.

The proportional integral temperature control coupled with agitation

supplied by a centrifugal pump located in the control housing allows

precise temperature control. Use of the gable cover provided is required to

maintain optimal temperature sensitivity.

Introduction and Unpacking

A high limit thermostat is provided and can be set to prevent heater

runaway in the event of temperature control failure.

The interior of the bath is constructed of stainless steel and is designed for

operation with distilled water or water solutions, such as water /ethylene

glycol with corrosion inhabitants added. The body is made from

galvanized steel and is painted for added protection. A drain is located at

the far left hand end of the bath. A stainless steel gable cover is also

provided with the bath.

The 240-volt units are identical in appearance to the 120-volt units.
