•Before initial use, or after transport, or after storage in humid or semi-hu-
mid environments, or anytime the instrument has not been energized for
more than 10 days, the instrument needs to be energized for a “dry-out”
period of 2 hours before it can be assumed to meet all of the safety re-
quirements of the IEC 1010-1. If the product is wet or has been in a wet
environment, take necessary measures to remove moisture prior to apply-
ing power such as storage in a low humidity temperature chamber operat-
ing at 50°C for 4 hours or more.
•DO NOT operate high temperature baths near flammable materials. Ex-
treme temperatures could ignite the flammable material.
•Overhead clearance is required. Do not place the instrument under a cabi-
net or other structure. Always leave enough clearance to allow for safe
and easy insertion and removal of probes.
•The instrument is intended for indoor use only.
•Ensure that you check the appropriate OSHA and local fire code regula-
tions for proper equipment required to suppress a fire for the fluid utilized
in the bath.
BURN HAZARD
•High temperatures may be present in this equipment. Fires and severe
burns may result if personnel fail to observe safety precautions.
•Ensure the bath DOES NOT contain any water and has been completely
dried prior to filling with fluid. Any trapped water can cause a steam ex-
plosion resulting in personal injury. If the bath has recently been filled
with water, ensure the inside of the drain tube is dry prior to filling the
bath with fluid.
•When immersing any object in the bath, ensure that you are not introduc-
ing anything into the bath that will react with the bath fluid. Ensure that
probes are DRY and free of contaminants. Read the MSDS (Material
Safety Data Sheet) for the bath fluid used.
•The bath is provided with an access cover. The access cover can be modi-
fied to allow the probes being calibrated to be inserted through the access
cover. The bath should be operated with the access cover on at all times.
Operating the bath without the access cover reduces stability, increases
out gassing of fluids, and increases the possibility of personal injury or
fire hazard.
•When removing probes from the bath DO NOT wipe probes down with a
paper towel. If the bath setpoint is high, the paper towel can ignite in your
hand. Provide a safe surface and situation for the probes to cool prior to
cleaning them.
•The bath generates extreme temperatures. Precautions must be taken to
prevent personal injury or damage to objects. Probes may be extremely
hot when removed from the bath. Cautiously handle probes to prevent
personal injury. Carefully place probes on a heat resistant surface or rack
until they are at room temperature.

Safety Information

•Be extremely careful when filling the bath and bringing it up to tempera-
ture. Most fluids expand with temperature. It is easy to add fluid, but ex-
tremely dangerous to remove hot fluid when the bath is over filled. DO
NOT fill the bath above the indicated fill line when the stirring is on. It
will overflow.
ELECTRICAL HAZARD
•These guidelines must be followed to ensure that the safety mechanisms
in this instrument will operate properly. The power cord of the instrument
is equipped with a three-pronged grounding plug for your protection
against electrical shock hazards. It must be plugged directly into a prop-
erly grounded three-prong receptacle. The receptacle must be installed in
accordance with local codes and ordinances. Consult a qualified electri-
cian. DO NOT use an extension cord or adapter plug.
•DO use a ground fault interrupt device. This unit contains a liquid. A
ground fault device is advised in case liquid is present in the electrical
system and could cause an electrical shock.
•Always replace the power cord with an approved cord of the correct rat-
ing and type. If you have questions, contact an 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.
•Keep all combustible materials away from the bath. Operate the bath on a
heatproof surface such as concrete. Provide a means of safety for contain-
ing any spill, which may occur.
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 unit 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 operation.
Ensure that the soft cutout is adjusted to the fluid characteristics of the ap-
plication. Failing to set the cutout to the limits of the bath fluid can result
in fire hazards and personal injury.
1.2.2 Cautions
To avoid possible damage to the instrument, follow these guidelines.
•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.

•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.
•Read Section 6, Bath Use, before placing the unit into service.
•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.
•Only authorized personnel should perform the Factory Reset Sequence 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.
•The bath is a precision instrument. Although it has been designed for op-
timum durability and trouble free operation, it must be handled with care.
Position the bath before the tank is 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.
•DO ensure the fluid is cleaned from the probes prior to immersing the
probe in the next bath. Clean your probe between each bath to avoid con-
tamination between bath fluids.
•Under filling the bath may reduce the bath performance and may possibly
damage the bath.
•When calibrating PRTs always follow correct calibration procedure and
calibrate from high temperatures to low temperatures with the appropriate
triple point of water checks. Never immerse a wet or cold PRT into a bath
filled with hot fluid. Severe damage to the PRT may result as well as per-
sonal injury to the calibration technician.
•This bath is not designed to be portable. Therefore, moving the bath once
it has been installed should be kept to a minimum. NEVER MOVE A
BATH THAT IS FULL OF “HOT” FLUID. This action could be ex-
tremely dangerous and could result in personal injury to the person mov-
ing the bath. If the bath is going to be placed in an area where it may need
to be moved frequently, Hart Scientific sells a special cart designed to ac-
commodate the bath. However, even with a cart the bath should not be
moved full of “hot” fluid. The fluid can splash causing injury or if the
bath and cart tip, the “hot” fluid could cause damage to the surrounding
area and personnel.
•If the bath must be moved, be sure to drain the fluid to prevent any injury.
To safely move the bath, two people are required. One person should lift

the bath by the tower, while the second person lifts from underneath the
bath tank.
•The control probe must be inserted through the lid into the bath fluid and
plugged into the socket at the back of the bath. DO NOT operate the bath
without the control probe properly inserted and attached. The bath will
not operate correctly without the control probe. Injury to operating per-
sonnel and permanent damage to the bath could occur.
