This manual contains important operating and safety
information. The user must carefully read and understand
the contents of this manual prior to the use of this equip-
ment.
Your Barnstead 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
codes. For safe operation, please pay attention to the
alert signals throughout the manual.
Warnings
To avoid electrical shock, this furnace must:
1. Use a properly grounded electrical outlet of cor-
rect voltage and current handling capacity.
2. Disconnect from the power supply prior to main-
tenance and servicing.
3. Have the door switch operating properly.
To avoid burns, this furnace must:
Not to be touched on the exterior or interior sur-
faces during use or for a period of time after
use.
To avoid personal injury:
1. Do not use in the presence of flammable or
combustible materials; fire or explosion may
result. This device contains components which
may ignite such materials.
2. Refer servicing to qualified personnel.
Safety Information

possibility of personal injury if you
come in contact with a surface during
use or for a period of time after use.
Caution
Cautions alert you to a possibility of
damage to the equipment.
Warning
Warnings alert you to a possibility of
personal injury.

Notes alert you to pertinent facts and
conditions.
Alert Signals

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 preexisting respiratory diseases. Refractory ceramic and refractory ceram-
ic 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
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 materials, or when
otherwise disturbing them in a manner which causes release of dust or fibers. By using proper handling pro-
cedures and protective equipment you can work safely with these insulating materials and minimize any expo-
sure. Refer to the appropriate Material Safety Data Sheets (MSDS) for information regarding proper handling
and recommended protective 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.
SAFETY INFORMATION

Intended Use
The Type F62700 furnace is a general laboratory and
heat treating furnace. For optimum element life, it is sug-
gested that this furnace be used for applications requiring
temperatures from 400°F (204°C) to 1600°F (871°C) for
continuous use, or temperatures from 1600°F (871°C) to
1832°F (1000°C) for intermittent use. Continuous use is
operating the furnace for more than 3 hours and intermit-
tent use is operating the furnace for less than 3 hours.
The unit consists of: 1) muffle heating chamber, 2) a mi-
croprocessor control and 3) a door interlock relay for user
safety.
General Usage
Do not use this product for anything other than its intend-
ed usage.
Principles of Operation
The furnace chamber incorporates a heating element that
is embedded into the side walls and top and back of heat-
ing chamber. The ceramic fiber oval muffle with four
heating surfaces creates even heat distribution within the
chamber. The temperature is controlled by a micropro-
cessor control with a type K Chromel/Alumel Thermocou-
ple. A fan is provided in the furnace to provide forced air
cooling for the temperature controller. A door safety
switch removes power to the heating elements whenever
the furnace door is opened.

Visually check for any physical damage to the shipping
container. Inspect the equipment surfaces that are adja-
cent to any damaged area. Open the furnace door and re-
move packing material from inside the furnace chamber.
Vacuum the chamber prior to use to remove the insulation
dust due to shipping.
The furnace is supplied with two hearth plates. Place the
hearth plates on the bottom of the chamber.
Install ceramic sleeve into top vent hole on furnace case.
Retain the original packaging material if re-shipment is
foreseen or required.
Unpacking
10
Site Selection
Install furnace on a sturdy surface and allow adequate
space for ventilation.
The electrical specifications are located on the specifica-
tion plate on the back of the furnace. Consult Barnstead
International if your electrical service is different than
those listed on the specification plate. Prior to connecting
your Type F62700 furnace to your electrical supply, be
sure the front power switch is in the “OFF” position.
Installation
Caution
Be sure ambient temperature does not
exceed 104°F (40°C). Ambients
above this level may result in damage
to the controller. Allow at least six
inches of space between the furnace
and any combustible surface. This
permits the heat from the surface case
to escape so as not to create a possi-
ble fire hazard.
Warning
Do not use in the presence of flamma-
ble or combustible chemicals. Fire or
explosion may result; this device con-
tains components which may ignite
such materials.
Warning
To avoid burns, this furnace must not
be touched on the exterior or interior
furnace surfaces during use or for a
period of time after use.
