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 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 unit 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 pa rameters.

1 Before You Start

DO NOT operate this instrument in an excessively wet, oily, dusty, or

•

dirty environment.

The unit is a precision instrument. Although it has been designed for opti

•

mum durability and trouble free operation, it must be handled with care. Position the unit before the tank is filled with fluid. Use the handles pro vided to move the unit. Due to the weight of the compressor, it may re quire two people to safely move the bath. If two people are used, place one person in the front and one person in the back of the unit, carefully slide hands under the unit and lift in unison. The area containing the com pressor will be heavier than the rest of the unit. Do not move a unit filled

with fluid.

Most probes have handle temperature limits. Be sure that the probe handle

•

temperature limit is not exceeded in the air above the instrument.

The instrument and any thermometer probes used with it are sensitive in

•

struments that can be easily damaged. Always handle these devices with care. Do not allow them to be dropped, struck, stressed, or overheated.

COLD BATHS

• Refrigerated baths require that the condensing coil be cleaned periodi-

cally. Accumulation of dust and dirt on the condenser will result in premature failure of the compressor.

• This bath has been equipped with a brownout and over voltage protection

device as a safety feature to protect the system components.

• Mode of Operation: This bath needs to be plugged into the line voltage

for at least 2 minutes before operation. This is only necessary for the first time that the bath is energized or when it is moved from one location to another. Turning the bath ON or OFF does not trigger the delay.

•

If a High/Low voltage condition exists for longer than 5 seconds, the bath de-energizes. An amber indicator on the back panel lights when this con dition exists.

•

Re-energization is automatic upon correction of the fault condition and af ter a delay cycle of about 2 minutes. If a fault condition exists upon appli cation of power, the bath will not energize.
