Safety Data Sheet) for the salt used. If you are still unsure if the material
you are going to introduce into the bath will react with the salt, refer to
the individual MSDS sheets for the three components that make up the
salt.
• 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 salt can cause the paper towel
to ignite in your hand. Provide a safe surface and situation for the probes
to cool prior to cleaning the salt from the probes.
• 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.
• Be extremely careful when filling the bath with salt and bringing it up to
temperature. Salt expands with temperature. It is easy to add salt, but ex-
tremely dangerous to remove hot molten salt because 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. This instrument must be plugged
into an outlet as listed in Section 3.1, Specifications. 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 properly grounded three-prong receptacle. The receptacle must be
installed in accordance with local codes and ordinances. Additionally, the
instrument has a Permanent Earth Ground that must be connected during
use. Consult a qualified electrician. DO NOT use an extension cord or
adapter plug.
• DO use a 30 mA 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.
