Alert Signals
6 Premium Large Muffle Thermo Scientific
Alert Signals
Warnings alert you to a possibility of personal injury.
Cautions alert you to a possibility of damage to the equipment.
Notes alert you to pertinent facts and conditions.
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.
Important Information
Your Thermo Scientific Thermolyne Type F6000 Model Furnace has been designed with function,
reliability and safety in mind. It is your responsibility to install it in conformance with local electrical
codes. For safe operation, please pay attention 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. 
If the equipment is used in a manner not specified by the manufacturer, protection provided by the
equipment may be impaired.
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 burns, this furnace must:
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.
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 material.
2. Refer servicing to qualified personnel.

Warning
Thermo Scientific Premium Large Muffle 7
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.
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 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 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) 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 1-800-553-0039.

Do not exceed operating temperatures shown in ““General Specification” on
page 11.” Exceeding these limits will result in severely reduced element life.
2 Introduction
Intended Use
10 Premium Large Muffle Thermo Scientific
Intended Use
The Type F6000 furnaces are general purpose laboratory and heat treating furnaces. For optimum
element life, we recommend observing these temperature ranges: from 100°C (212°F) to 1093°C
(2000°F) continuous use or from 1093°C (2000°F) to 1200°C (2192°F) for intermittent use. (-60)
Ashing models continuous temperature range is 100°C (212°F) to 975°C (1787°F). Continuous use is
operating 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 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. The (-60) models operate the same as the other models except at a lower temperature and
can inject gas into the chamber.

Unpacking
(-60) models are supplied with two stainless steel trays, handle and porcelain pegs.
The Type 6000 furnaces do not come with a power cord because current
requirements are too great to be handled by ordinary power cords and standard wall
supply. (F6010 and F6018 are supplied with cord and plug).
1. Visually check for any physical damage 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.
5. Retain the original packaging material if reshipment is foreseen or required.

Be sure ambient temperature does not exceed 40°C (104°F). Ambient above this level
may result in damage to the controller.
Allow at least six inches of space between the furnace, at least 40 inches above the
furnace and any combustible surface. This permits the heat from the furnace case to
escape so as not to create a possible fire hazard.
To avoid electrical shock, this furnace must be installed by a competent, qualified
electrician who ensures compatibility among furnace specifications, power source and
grounding code requirements. (Disregard Step 2 if you have Model F6010 or
F6018).
For supply connections, use 10 AWG or larger wires suitable for at least 90°C. Failure
to observe this caution could result in damage to furnace.
Do not use in the presence of flammable or combustible materials; fire or explosion
may result. This device contains components which may ignite such material.
Caution: Hot Surface. 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.

Electrical Conditions in the EU
Electrical Conditions for operating the furnaces in the EU:
The furnaces are intended for use at a network supply with a maximum system impedance of Zmax =
0.0325 Ohmat the point of connection, according to EN 61000-3-11 clause 6.2.2. The user has to
ensure that the device is operated on a network supply that meets these requirements. If necessary, the
system impedance can be confirmed by the energy supplier.
