Safety Information
Your Thermolyne furnace has been designed with function,
reliability, and safety in mind. It is the user’s responsibility to
install it in conformance with local electrical codes. For safe
operation, please pay attention to the alert boxes through-
out the manual.
Because of the nature of this product, considerably more
care is required in operating and servicing this furnace than
for lower temperature laboratory furnaces. For maximum
safety and longest furnace life, be sure to observe the
various cautions and warnings throughout this manual.
Alert Boxes
WARNING
Warning alerts apply when there is a
possibility of personal injury.
CAUTION
Caution alerts apply when there is a
possibility of
damage to the equipment.
NOTE
Notes alert the manual user to
pertinent facts and
conditions.
HOT SURFACE
Hot surfaces alert you to a possibility
of personal
injury if you come in contact with a
surface during use or for a period of
time after use.
Safety Information

WARNING
To avoid electrical shock, this furnace must:
1. Be installed by a competent, qualified electrician who
insures compatibility among furnace specifications,
electrical source and grounding code requirements.
2. Always be disconnected from the electrical supply
prior to maintenance and servicing.
To avoid personal injury:
1. Do not stand directly in front of the chamber without
wearing a heat resistant face shield, gloves and apron.
2. Do not operate or clean furnace without proper eye
protection.
3. Do not use in the presence of flammable or combus-
tible materials; fire or explosion may result.This
device contains components which may ignite such
materials.
4. Refer servicing to qualified personnel.
5. Caution: Hot Surface. Avoid Contact.
6. To AVOID EYE DAMAGE in operating or cleaning
furnace, proper eye protection must be worn.
7. To AVOID BURNS, do not stand directly in front of the
chamber without wearing a heat resistant faceshield,
gloves and apron.
8. To AVOID FIRE, do not place combustible materials
where exposed to heat from open door.
HOT SURFACE
Caution: Hot Surface. Avoid Contact.
SAFETY INFORMATION

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 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) fo 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
REFER SERVICING TO QUALIFIED PERSONNEL.

Intended Use
Types 461 and 462 are general purpose laboratory
furnaces
intended for applications requiring temperatures from
800-1700
degrees C.
General Usage
Do not use this product for anything other than its
intended usage.
Principles of Operation
The chamber section is heated by six (in type F46100
urnaces) or eight (in type F46200 furnaces) Super
Kanthal 33 heating elements suspended in a chamber
made of alumina and silica high temperature refractory
fiber.
This high temperature refractory fiber is in the form of
blocks which line the inside of the chamber. Because of
the
stresses caused by extremely high temperature opera-
tion, these blocks will show some surface cracking.This
cracking is not detrimental to the operation of the fur-
nace.
A precious metal type B thermocouple senses the
temperature in the chamber and transmits this informa-
tion to the temperature control in millivolts.
NOTE
The fans operate continuously, even
when the circuit breaker is OFF, to assure
that the control section and the terminals
of the heating elements are continuously
ventilated. Without ventilation, residual
heat from the furnace chamber can cause
overheating after the furnace is turned off.
CAUTION
Do not completely remove electricity from
the furnace until chamber temperature
falls below 500°C. Do not touch exposed
elements.
Description

8
The control section consists of a temperature controller, a
current controller, a transformer, a contactor (relay), a
circuit breaker, and a pilot light.
The temperature controller senses the furnace temperature
(by means of the thermocouple) and adjusts electricity to
the heating elements by means of the current controller.
The current controller controls electricity to the heating
elements by adjusting the magnitude of the electrical
current (rather than turning the electricity completely on or
off).This is the preferred method of controlling electricity to
molybdenum disilicide heating elements.
The transformer supplies the proper electrical voltage to the
heating elements.
The contactor removes electricity from the heating elements
if the furnace temperature equals or exceeds the high limit
set point of the controller
The circuit breaker is used to turn the furnace on and off
and also protects the electrical supply in the event that the
furnace draws too much electrical current.
The pilot light indicates that the circuit breaker is ON and
that the controller is being supplied with electricity.
A fan is provided in each section of the furnace to provide
forced air cooling.
Types of Controllers
1. The automatic (single set point) digital model enables the
user to program a single set point temperature which the
furnace will heat and hold.
2. The 4 program, programmable digital model enables the
operator to program up to 8 ramp segments (heat-up or
cool-down rate) and 8 dwell segments (soak) for applica-
tions that require time and temperature relationship for
up to 4 separate or linkable programs.
3. The 15 program, programmable digital model enables
the operator to program up to 8 ramp segments (heat-up
or cool-down rate) and 8 dwell segments (soak) for up to
15 separate or linkable programs.

NOTES:*Inrush power and current.
# Power and current required to maintain maximum temperature after stabilization.
The maximum current is determined by the limiting factor set by the current controller.In the event that 40 amperes is not available, the
current controller may be set to limit the current to some smaller value at the expense of a somewhat longer heat-up time.
The variation in current is a result of molybdenum disilicide heating elements
having a large decrease in resistance with increasing temperature.
NOTES:The maximum ramp rates for this furnace for heat-up are: 100°C per minute from 25°C-1000°C and
15°C per minute from 1000°C-1700°C.
