•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 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.
•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 unit opera- tion. 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 Section , Heat Transfer Fluid, for specific information on bath fluids and Section , Cutout.

Cautions
•THE DRAIN VALVE MUST BE INSTALLED ON THE BACK OF THE BATH BEFORE ATTEMPTING TO FILL THE TANK WITH FLUID. See Section 5.3, page 17 for drain installation instructions.
•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.
•DO NOT overfill the bath. Overflowing liquid may damage the electrical system. Be sure to allow for thermal expansion of the fluid as the bath temperature increases. See Section 5.3, Bath Preparation and Filling, for specific instructions.
•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 refrigeration may be damaged or the lifetime shortened if the
•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.
