Please note the following WARNINGS:
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 con-
tains refractory ceramic, refractory ceramic fiber or fiber-
glass insulation, which can produce respirable dust or
fibers during disassembly. Dust or fibers can cause irrita-
tion 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 indi-
cate that there is no risk of exposure to dust or respirable
fibers resulting from operation of this product under nor-
mal 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 appro-
priate Material Safety Data Sheets (MSDS) for informa-
tion regarding proper handling and recommended protec-
tive equipment. For additional MSDS copies, or additional
information concerning the handling of refractory ceramic
products, please contact the Customer Service
Department at Barnstead International at 1-800-553-0039.
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 el-
ement failure, therefore, when possible remove the fume
forming material before heating. (e.g., cleaning cutting oil
from tool steel.)
Housekeeping is vital to your electric furnace - KEEP IT
CLEAN. Run your furnace up to 871°C empty occasional-
ly to burn off the contamination that may exist on the in-
sulation and elements. Maintain 871°C for at least 4 hrs.
