Preventative Maintenance

WARNING

THIS FURNACE CONTAINS REFRACTORY CERAMIC INSULATION WHICH CAN PRODUCE

RESPIRABLE FIBERS AND DUST WHEN HANDLED. THESE FIBERS CAN CAUSE

IRRITATION AND CAN AGGRAVATE PRE-EXISTING RESPIRATORY DISEASE. THE

INTERNATIONAL AGENCY FOR RESEARCH ON CANCER (IARC) HAS CLASSIFIED

REFRACTORY CERAMIC FIBER AS POSSIBLY CARCINOGENIC.

AFTER SERVICE REFRACTORY CERAMIC FIBER DUST MAY CONTAIN CRYSTALLINE

SILICA, WHICH MAY CAUSE LUNG DAMAGE (SILICOSIS) AND WHICH HAS BEEN

CLASSED BY IARC AS A PROBABLE CARCINOGEN.

The refractory ceramic materials are located in the door, the hearth collar bricks, and in the

chamber of the furnace. Tests performed by the manufacturer indicate that there is no

significant risk of exposure to dust or respirable refractory ceramic fiber resulting from

operation of the equipment under normal conditions. However, there may be a risk of

exposure to respirable refractory ceramic dust or fiber when repairing or maintaining the

insulating materials, or when otherwise disturbing the materials in a manner which causes

release of dust or fibers therefrom. Through the use of proper handling procedures you can

work safely with these insulating materials and minimize any exposure. Accordingly, before

you repair or replace any insulating materials, or perform any other servicing on this product

which could disturb or cause exposure to dust from insulating materials, you should consult

the appropriate Material Safety Data Sheets (MSDS’s) for such products with respect to

proper handling and appropriate protective equipment. For additional MSDS’s, or additional

information concerning the handling of refractory ceramic products, please contact the

Customer Service Department of Barnstead/Thermolyne Corporation.

REFER SERVICING TO QUALIFIED PERSONNEL.

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.)

Housekeeping is vital to your electric furnace - KEEP IT CLEAN. Run your furnace up to 1600°F empty

occasionally to burn off the contamination that may exist on the insulation and elements. Maintain 1600°F

for at least 4 hrs. to insure complete ashing of foreign materials.

Element life is reduced somewhat by repeated heating and cooling. If the furnace is to be used again

within a few hours, it is best to keep it at the operating temperature or at a reduced level such as 500°F

(260°C).
