BATH FLUIDS
•
Fluids used in this unit 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.
•
Utilization of a vent hood or other ventilation system is required for sili-
con oil at high temperatures.
•
The unit is equipped with a soft cutout (user settable firmware) and a hard

CAUTIONS
•
Always operate this instrument at room temperature between 41°F and
104°F (5°C to 40°C). Allow sufficient air circulation by leaving at least 6
inches (15 cm) of clearance around the instrument.
•
When filling the tank, ensure the heating coils are completely covered.
DO NOT fill above the stir baffle (see Figure 1, on page 13).
•
DO NOT
overfill the bath. Overflowing fluid may damage the electrical
system. Be sure to allow for thermal expansion of the fluid as the bath
temperature increases. See Section 5.5, Bath Preparation and Filling, for
specific instructions.
•
Regardless of the fluid used,
DO NOT
exceed the recommended fluid
viscosity.
•
Read Section 6, Bath Use, before placing the unit into service.
•
DO NOT turn on the bath without fluid in the tank and the heating coils
fully immersed. See Section 7.3.1, Fluid Expansion Reservoir, for infor-
mation on fluid expansion reservoir use.
•
DO NOT
change the values of the bath calibration constants from the fac-
tory set values. The correct setting of these parameters is important to the
safety and proper operation of the unit.
•
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 pa-
rameters.
•
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.
