Fisher Isotemp Water Baths
Congratulations on your new Fisher Isotemp
Water Bath.
Isotemp Water Baths offer the versatility
needed to handle virtually any clinical
laboratory procedure — incubation,
inactivation, agglutination — as well as most
serological, pharmaceutical, biomedical, and
industrial procedures.
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 limitations).
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 evaporation while helping to
maintain a uniform, constant temperature.
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 operating 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.
The calibration of the water bath can be
adjusted to optimize 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 temperature can only be
changed by entering a specific set menu
first. This ensures that the set point cannot
be accidentally altered during extended or
230 VAC
unattended operation.
To allow you to change the configuration

of some units, and to permit easy servicing,
your water bath provides front service

To avoid electrical shock, always:
Lid
•
Connect the water bath to a properly
grounded electrical outlet of the correct
15-462-21
voltage and current handling capacity.
Check the nameplate on the back of the
15-462-S21
SS
unit for the voltage and current rating.

Instructions
To avoid personal injury:
•
Do not use in the presence of flammable or
combustible 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
temperature 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
flammable. 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,
hydrofluoric acid, hydrobromic acid,
hydroiodic acid, sulfuric acid, or chromic
acid.
−
Weak salt solutions containing sodium
chloride, calcium chloride, chromate or
chromium compounds.
−
Deionized water.
−
Most photographic solutions.
•
Do not use a flammable liquid. A fire hazard
may result. This unit is not explosion proof.
Unit contains components which may ignite
such materials.
•
Use appropriate hand and eye protection when
handling hazardous chemicals.
•
The interior of the unit can reach temperatures
that can cause burns. Avoid contact. The unit
can remain hot without visual indication for
some time after power is turned off.
•
If you will use the water bath with any liquid
that will give off fumes, be sure to operate the
water bath in a fume hood or with proper
ventilation.
•
Use the cover to reduce evaporation and to
permit reaching higher temperatures.
•
Hot liquids pose a burn hazard. Be careful not
to reach into the bath when it contains hot
liquids. Also be careful of steam rising from
hot liquids.
•
The unit is intended to be operated with liquid
in the chamber. However, it will not be
damaged if it temporarily runs dry.
•
Do not use in highly corrosive atmospheres;
corrosive fumes and spillage may damage the
unit and its internal components, creating a
shock hazard.
•
Fumes from acidic solutions cause corrosion
of the stainless steel reservoir. Care should be
taken to maintain a neutral pH at all times.
•
Refer servicing to qualified personnel.
•
Do not place containers directly on bottom of
chamber. Bottom can get extremely hot if no
liquid is in the chamber. Always use the
diffuser tray
