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.
