WARNING
This warning is presented for compliance with California Proposition 65 and other regulatory agencies and only
applies to the insulation in this product. This product contains refractory ceramic, refractory ceramic fiber or
fiberglass insulation, which can produce respirable dust or fibers during disassembly. Dust or fibers can cause
irritation and can aggravate pre-existing respiratory diseases. Refractory ceramic and refractory ceramic fibers
(after reaching 1000°C) contain crystalline silica, which can cause lung damage (silicosis). The International
Agency for Research on Cancer (IARC) has classified refractory ceramic fiber and fiberglass as possibly
carcinogenic (Group 2B), and crystalline silica as carcinogenic to humans (Group 1).
The insulating materials can be located in the door, the hearth collar, in the chamber of the product or under the
hot plate top. Tests performed by the manufacturer indicate that there is no risk of exposure to dust or respi-
rable fibers resulting from operation of this product under normal conditions. However, there may be a risk of
exposure to respirable dust or fibers when repairing or maintaining the insulating materials, or when otherwise
disturbing them in a manner which causes release of dust or fibers. By using proper handling procedures and
protective equipment you can work safely with these insulating materials and minimize any exposure. Refer to
the appropriate Material Safety Data Sheets (MSDS) for information regarding proper handling and recom-
mended protective equipment. For additional MSDS copies, or additional information concerning the handling
of refractory ceramic products, please contact the Customer Service Department at Barnstead|Thermolyne
Corporation at 1-800-553-0039.
WARNING
Disconnect from the power supply prior to maintenance and servicing.
Refer servicing to qualified personnel.
This unit is equipped with a venting system on the top of the furnace. This is for the removal of fumes from the
chamber of the unit. Contamination is a major cause of element failure, therefore, when possible remove the
fume forming material before heating. (e.g., cleaning cutting oil from tool steel.)
