Alert Signals
Important Information
Your Thermo Scientific Thermolyne F30400 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:
Not be touched on the exterior or interior surfaces 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.
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.

1 Safety Information
Warning
Thermo Scientific Large Tabletop Muffle 7
Warning
Please note the following WARNINGS:
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 1-800-438-4851.

2 Introduction
Intended Use
10 Large Tabletop Muffle Thermo Scientific
Intended Use
The Type 30400 furnaces are general purpose laboratory and heat treating furnaces. For optimum
element life, we recommend observing these temperature ranges: from 400°F (204°C) to 1800°F
(982°C) for continuous use, or temperatures from 1800°F (982°C) to 2000°F (1093°C) for
intermittent use. Continuous use is operating the furnace for more than 3 hours and intermittent use is
operating the furnace for less than 3 hours.
The unit consists of:
1. a heating chamber;
2. an automatic proportioning digital set, digital read control with over-temperature protection and
3. a door interlock relay for user safety.
The Type 30400 Programmable furnace is designed to control a programmed temperature profile. The
profile is in the format of ramps and dwell segments. The first ramp, RAMP 1, starts at the initial
measured furnace temperature. This ramp is positive going at a programmed rate until the
programmed level is reached. The setpoint will stay at this level for a period determined by the setting
of DWELL 1. Additional positive or negative going ramps are now initiated starting at the level at the
end of DWELL 1. When the second ramp reaches the second programmed level, the setpoint stays at
that level for the duration of the segment. Depending upon the model ordered, additional ramp and
dwell segments may be added. See specific model number in proceeding chart for total number of
program segments.
4. The Type 30400 Automatic furnace is designed as a single set point controller which reaches and
maintains one temperature value.
General Usage
Do not use this product for anything other than its intended usage.
When in the program RUN mode, the programmable controller serves to provide a
programmed temperature profile as described earlier.When in the single setpoint
automatic mode, the unit serves as an automatic temperature controller.

Principles of Operation
Thermo Scientific Large Tabletop Muffle 11
Principles of Operation
Furnace: The furnace chamber is heated by four electric resistance heaters which are embedded in a
refractory material. The chamber is insulated with ceramic fiber insulation. The temperature is
controlled by an automatic proportioning controller using a platinel thermocouple to feed back
information. The control is located under the furnace chamber and is well insulated from the heat
generated in the furnace chamber. The temperature is controlled by one of three types of controllers.

Unpacking
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.

Site Selection
18 Large Tabletop Muffle Thermo Scientific
Site Selection
Install furnace on a sturdy surface and allow space for ventilation.
Electrical Connections
1. The electrical ratings are located on the specification plate on the back of the furnace. Consult
customer service if your electrical service is different than those listed on the specification plate. Be
sure the front power switch is in the OFF position before connecting the furnace to your electrical
supply.
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= 0.0229 ohm at 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.
Be sure ambient temperature does not exceed 40°C (104°F). Ambient above this level
may result in damage to the controller. The recommended ambient temperature is
17°C to 27°C (62.6°F to 80.6°F).
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 always use a properly grounded outlet of
correct voltage and current handling capacity.
