Table of Contents
Your Barnstead Thermolyne Type 47900 or
48000 Furnace has been designed with function,
reliability and safety in mind. It is your responsi-
bility to install it in conformance with local electri-
cal codes. For safe operation, please pay atten-
tion to the alert signals throughout the manual.
This manual contains important operating and
safety information. You must carefully read and
understand the contents of this manual prior to
the use of this furnace.
Warnings
To avoid electrical shock, this furnace must:
1. Use a properly grounded electrical outlet
of correct voltage and current handling
capacity.
2. Be disconnected from the power supply
prior to maintenance and servicing.
3. Have the door switch operating properly.
To avoid personal injury:
1. Do not use in the presence of flammable
or combustible materials; fire or explo-
sion may result. This device contains
components which may ignite such mate-
rial.
2. Caution: Hot Surface - Avoid Contact. To
avoid burns, do not touch the exterior or
interior surfaces of this furnace during
use or for a period of time after use.
3. Always wear safety glasses or a safety
shield and high temperature gloves when
loading or unloading the furnace. Long
sleeved, fire retardant clothing and a fire
retardant apron is also recommended.
4. Refer servicing to qualified personnel.

Safety Information
Warning
Warnings alert you to a possibility of
personal injury.
Caution
Cautions alert you to a possibility of
damage to the equipment.
Note
Notes alert you to pertinent facts and
conditions.
Alert Signals
Hot Surface
Hot surfaces alert you to the possibility
of personal injury if you come in contact
with a surface during use or for a period
of time after use.
Warning
This warning is presented for compliance with
California Proposition 65 and other regulatory agen-
cies and only applies to the insulation in this prod-
uct. This product contains refractory ceramic, refrac-
tory 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 dam-
age (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 man-
ufacturer indicate that there is no risk of exposure to
dust or respirable 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 materi-
als, or when otherwise disturbing them in a manner
which causes release of dust or fibers. By using
proper handling procedures and protective equip-
ment 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 han-
dling of refractory ceramic products, please contact
the Customer Service Department at Barnstead
International at 1-800-553-0039.

SAFETY INFORMATION
Warning
Refer Servicing to qualified per-
sonnel.
Intended Use
The Type F47900 and F48000 furnaces are
general purpose laboratory and heat treating
furnaces. For optimum element life,
Barnstead International recommends observ-
ing these temperature ranges: from 100°C
(212°F) to 1093°C (2000°F) continuous use
or from 1093°C (2000°F) to 1200C (2192°F)
for intermittent use. Continuous use is operat-
ing the furnace for more than 3 hours and
intermittent use is operating the furnace for
less than 3 hours.
All furnaces consist of: 1) a vented heating
chamber; 2) a temperature controller; and 3)
a door safety switch for operator safety.
General Usage
Do not use this product for anything other
than its intended usage.
Principles of Operation
The furnace chamber is heated by open coil
electric resistance elements and is insulated
with ceramic fiber insulation. The controller is
located under the furnace chamber and is
well insulated from the heat generated in the
furnace chamber. A door safety switch
removes power to the heating elements
whenever the furnace door is opened. The
temperature is controlled by one of three
types of controllers.

Introduction
Caution
Do not exceed operating temperatures
shown in “General Specifications.”
Exceeding these limits will result in
severely reduced element life.

1. Visually check for any physical dam-
age to the shipping container.
2. Inspect the equipment surfaces that
are adjacent to any damaged area.
3. Open the furnace door and remove
the packing material from inside the
furnace chamber.
4. Vacuum the chamber prior to use to
remove the insulation dust due to
shipment. (The Type 48000 furnace is
supplied with one ceramic shelf.)
5. Retain the original packaging material
if reshipment is foreseen or required.
Unpacking
9
Site Selection
Install furnace on a sturdy surface and allow
adequate space for ventilation.
Electrical Connections
The electrical ratings are located on the spec-
ification plate on the back of the furnace.
Consult Barnstead International if your electri-
cal service is different than those listed on the
specification plate. Be sure the front power
switch is in the OFF position before connect-
ing the furnace to your electrical supply.
Installation
Caution
Be sure ambient temperature does not
exceed 40°C (104°F). The recommended
ambient temperature is 17°C - 27°C.
Ambients above this level may result in
damage to the controller.
Warning
To avoid electrical shock, this furnace
must always use a properly grounded
outlet of correct voltage and current han-
dling capacity.
Caution
Allow at least six inches of space
between the furnace and any combustible
surface. This permits the heat from the
furnace case to escape so as not to cre-
ate a possible fire hazard.
10
Power Switch
Both the ON/OFF power switch and the digital
display will illuminate when power is switched
ON. The furnace will begin to heat to its con-
troller's current setpoint. (See the instructions
for your type of controller for information on
checking and setting the setpoint.)
Cycle Light
The amber cycle light will illuminate whenever
the power is being applied to the heating ele-
ments. The cycle light will turn on and off as
the furnace reaches the setpoint.
Door Safety Switch
The door safety switch removes power from
the heating elements when the door is
opened. Open and close the door a few
times; note that the amber CYCLE light will
switch off when the door is opened. If this
condition is not true, consult the
Troubleshooting section before proceeding.
This check must be done when the furnace is
heating and the cycle light is illuminated.
Operation, All Models
Warning
To avoid personal injury do not use in the
presence of flammable or combustible
chemicals; fire or explosion may result.
This device contains components which
may ignite such materials.
Hot Surface
Caution: Avoid Contact. To avoid burns,
this furnace must not be touched on the
exterior or interior surfaces during use or
for a period of time after use.
Warning
To avoid electrical shock, the door safety
switch must be operating properly.
Warning
Always wear safety glasses or a safety
shield and high temperature gloves when
loading or unloading the furnace. Long
sleeved, fire retardant clothing and a fire
retardant apron is also recommended.
