Congratulations on your new Thermo Scientific Precision
Water Bath.
Precision Water Baths offer the versatility needed to han-
dle virtually any clinical laboratory procedure — incuba-
tion, inactivation, agglutination — as well as most serolog-
ical, pharmaceutical, biomedical, and industrial proce-
dures.
These water baths are available with chamber capacities
of 2, 5, 10, 20, and 28 liters. The 2 liter unit is available
configured with either a standard or shallow chamber.
Also, a dual chamber unit is available with 5 and 10 liter
chambers, with independent controls for each. All units
are available to operate from either 120 or 230 volts.
The baths work equally well with water or bath oil as the
medium. All models offer the same temperature ranges:
ambient to 60°C without the supplied cover, and ambient
to 100°C with the cover in place (within physical limita-
tions).
These baths are microprocessor controlled for precise
temperatures and reliable, trouble-free operation. Dual
thermostats — one controlling the set point temperature
and the other operating as a safety — virtually eliminate
the possibility of overheating. Although not designed to
operate dry, the bath will not be damaged if it is allowed
to run dry.
An energy-saving removable cover helps to reduce evap-
oration while helping to maintain a uniform, constant tem-
perature. The cover also allows the water bath to reach
higher temperatures. The hinged, see-through gable
cover features unique “fins” that keep hands away from
hot vapors for easier, safer opening. The cover stays
open at the 90° position or, because of its quick-attach
hinge, can be lifted off completely to accommodate large
glassware.
A plastic rim remains cool to the touch even when operat-
ing the bath at maximum temperature.
The unit features a power-on self-test of vital circuitry.
This test will automatically be performed each time you
turn on the unit. If problems are detected, the system will
indicate a warning message on the display.
Introduction

The calibration of the water bath can be adjusted to opti-
mize its accuracy for the temperature that is used most
often in your application. This can be accomplished
through a simple procedure accessed from the front
panel.
As a convenience, a drain pump is supplied with 10, 20,
28, and dual 5/10 liter models.
All controls are conveniently located on the front panel for
easy access. To assure set point security, the tempera-
ture can only be changed by entering a specific set menu
first. This ensures that the set point cannot be accidental-
ly altered during extended or unattended operation.
To allow you to change the configuration of some units,
and to permit easy servicing, your water bath provides
front service access to the controller without having to
empty the bath.
The water bath features corrosion resistant construction
throughout to withstand the rigors of daily lab use.

These instructions contain important operating and safety
information. The user must carefully read and understand
these instructions before using the water bath.
Your unit has been designed to optimize function, reliability,
safety, and ease of use. It is the userʼs responsibility to install
the bath in conformance with local electrical codes.
To avoid electrical shock, always:
• Connect the water bath to a properly grounded elec-
trical outlet of the correct voltage and current han-
dling capacity. Check the nameplate on the back of
the unit for the voltage and current rating.
• Disconnect the unit from the power outlet prior to
maintenance and servicing. Note: 230V units are
double pole, neutral fusing.
To avoid personal injury:
• Do not use in the presence of flammable or com-
bustible materials; fire or explosion may result. This
device contains components which may ignite such
materials.
• Do not remove or modify the grounded power plug.
Use only properly grounded outlets to avoid a shock
hazard. This unit is not rated for use in hazardous
atmospheres.
• Do not continue to operate the bath if the tempera-
ture control fails (displays an “E” code or controls
erratically) or the backup control fails (red safety
light glows continuously when turned completely
clockwise or fails to light when turned completely
counterclockwise).
• Select a fluid that is not corrosive and is not flamma-
ble. The following fluids are not recommended and
may damage the unit:
- Chlorides or bleach.
- Strong concentrations of any acid.
- Strong concentrations of any salt.
- Weak concentrations of hydrochloric acid, hydroflu-
oric acid, hydrobromic acid, hydroiodic acid, sulfuric
acid, or chromic acid.
