Fluids used in this bath may produce noxious or toxic fumes under
certain circumstances. Consult the fluid manufacturer's MSDS
(Material Safety Data Sheet). Proper ventilation and safety
precautions must be observed.
• The instrument is equipped with a soft cutout (user settable
firmware) and a hard cutout (set at the factory). Check the flash
point, boiling point, or other fluid characteristic applicable to the
circumstances of the bath operation. Ensure that the soft cutout is
adjusted to the fluid characteristics of the application. As a
guideline, the soft cutout should be set 10°C to 15°C below the flash
point of the bath fluid. See Transfer Fluid (Chapter 8), for specific
information on bath fluids and Cutout (Chapter 9).
Always operate this instrument at room temperature
between 41°F and 122°F (5°C to 50°C). Allow sufficient air
circulation by leaving at least 6 inches (15 cm) of clearance
around the instrument.
When filling the tank, ensure the immersion coils are
completely covered. DO NOT fill above the stir baffle (see
Figure 4-1).
DO NOT overfill the bath. Overflowing fluid may damage
the electrical system. See Bath Preparation and Filling
(Chapter 5) for specific instructions.
Read Chapter 6, Bath Use, before placing the bath into
service.
DO NOT turn the bath on without fluid in the tank and the
heating coils fully immersed. See Fluid Expansion
Reservoir (Chapter 7) for more information on Fluid
Expansion Reservoir use.
No matter what fluid is used, DO NOT exceed the
recommended fluid viscosity.
DO NOT change the values of the bath calibration
constants from the factory set values. The correct setting
of these parameters is important to the safety and proper
operation of the bath.
The refrigeration may be damaged or the lifetime shortened
if the set-point temperature is set above 60°C for more than
one hour with the refrigeration manually on. Ensure that
the refrigeration is off when the bath is used above 60°C.
The Factory Reset Sequence should be performed only by
authorized personnel if no other action is successful in
correcting a malfunction. You must have a copy of the
most recent Report of Test to restore the test parameters.
DO NOT operate this instrument in an excessively wet, oily,
dusty, or dirty environment. Silicone oils require additional
ventilation to prevent an oily, dirty environment.
