DO use a ground fault interrupt device. This instrument contains a fluid. A
ground fault device is advised in case fluid is present in the electrical system
and could cause an electrical shock.
Always replace the power cord with an approved cord of the correct rating and
type. If you have questions, contact a Authorized Service Center (see section
1.3).
High voltage is used in the operation of this equipment. Severe injury or death
may result if personnel fail to observe the safety precautions. Before working
inside the equipment, turn off the power and disconnect the power cord.
BATH FLUIDS
Fluids used in this bath may produce noxious or toxic fumes under certain cir-
cumstances. 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. En-
sure that the soft cutout is adjusted to the fluid characteristics of the applica-
tion. As a guideline, the soft cutout should be set 10°C to 15°C below the flash
point of the bath fluid. See section 8.1, Bath Fluid, for specific information on
bath fluids and section 9.8, Cutout.

CAUTIONS

Always operate the instrument in room temperatures listed in section 3.2, En-
vironmental Conditions. Allow sufficient air circulation by leaving at least 15
cm (6 inches) of clearance around the instrument.
DO NOT overfill the bath. Overflowing fluid may damage the electrical sys-
tem. See section 5.3, Bath Preparation and Filling, for specific instructions.
Read section 6, Bath Use, before placing the bath into service.
DO NOT turn the bath on without fluid in the tank.
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 person-
nel 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.
