A. Safety
A.1 Owners, Operators, and Maintenance
This manual uses note, caution, and warning symbols throughout to draw your attention
to important operational and safety information.
Read and understand all instructions and safety precautions listed in this manual before
installing or operating your unit. If you have any questions regarding operation of the unit
or instructions in this manual, contact our Service Engineering Department at +1-724-
283-1212.
In addition to the safety warnings listed here, warnings are posted throughout the
manual. Read and follow these important instructions. Failure to observe these
instructions can result in permanent damage to the unit, signicant property damage,
personal injury, or death.
Read and understand all instructions and safety precautions listed in this
manual before installing or operating your unit. If you have any questions
regarding operation of the unit or instructions in this manual, contact our
Service Engineering Department.
Thoroughly understand the safety features and operation of the
equipment. This manual will provide operators with safety concerns and
general procedures. Be familiar with correct operating principles and
use good judgment. Also refer to the appropriate manuals for system
component safety instruction manuals.
Use caution when working with elements at elevated temperatures.
Prevent burns by wearing protective clothing, and follow safety, operation,
and maintenance procedures described in the appropriate instruction
manuals.
Avoid radiating heat. Items with a large mass retain heat for a long time.
First-degree burns may occur from heat radiation as well as from direct
contact with a hot surface.
Obey all national and local electric code requirements. Furnaces and
control systems must be grounded and wired according to national and

2Series 31XX, 32XX Furnaces | A. Safety
local electrical code requirements.
Handle the furnace carefully. Avoid dropping and jarring the furnace.
Avoid damage to cables. Do not let the power cables touch the heated
furnace shell.
Do not exceed maximum operating temperature. Operate the furnace
and accessories within the appropriate temperature range. Refer to the
appropriate manuals.
Dangerous high voltages present. Do not attempt to open the enclosure
or gain access to areas where you are not instructed to do so. Refer
servicing to qualied service personnel only.
Caution - Injury to the operator could occur if operational procedures are
not followed. Follow all steps or procedures as instructed and refer to
accompanying documents.
Ventilation – Slots and openings in the cabinet are provided for ventilation
and to ensure reliable operation of the product. To protect the unit from
overheating, those openings must not be blocked or covered. This product
should not be placed in a built-in installation, such as a wall cut-out unless
proper ventilation is provided. Hot temperatures will result.
Refer to manual. Before tuning the temperature controller, be sure to read
and understand the tuning instructions in the controller manual. Follow all
operating and other instructions carefully.
If it should become necessary to clean this equipment, disconnect the unit
from its power source rst. Do not use liquid cleaners, aerosols, abrasive
pads, scouring powders or solvents, such as benzene or alcohol. Use a
soft cloth lightly moistened with a mild detergent solution. Ensure the
surface cleaned is fully dry before reconnecting power.
Do not attempt to operate the temperature control system in ambient
temperatures higher then 120° F (49° C) without providing a cooling fan
or air conditioning.

Do not use a temperature control system with a power output rating lower
than the current rating of the furnace.
Use the same thermocouples as indicated on the setpoint controller.
Other types will result in faulty control which may cause damage from
overheated components.
When changing fuses in current limiting power controllers, use only the
fuse type and size specied by the power controller manufacturer.
Use interconnecting cables of the proper gauge to match the ratings on
the data labels for the furnace and controller.
Do not connect any measuring or controlling devices to the thermocouple
other than the main temperature controller.
Use thermocouple extension wires and connectors that match the
thermocouple type being used. Use of copper wires will cause errors in
readings and result in faulty control.
Do not allow the bare thermocouple wires or any part of the thermocouple
to come in contact with other metals. This could induce incorrect voltages
and result in erroneous readings and faulty control.
A.2 Environmental Conditions
The furnace is meant for use in laboratory/factory settings in a dry, clean work
environment. There should be a clean and sturdy work surface both at a reasonable
working height and away from any water, gas, or electrical hazards. The work surface
should be able to support more than the weight of the unit itself. The indoor area should
be well ventilated and containing no open ames or materials that may constitute a re
hazard.
• Temperature of 15° C to 35° C
• Relative humidity not more than 75%
• Air pressure of 75 kPa to 106 kPa
• No hard-frost, dew, percolating water rain, solar irradiation, etc.

B. Introduction
B.1 Unpacking
Retain all cartons and packaging materials until the unit is operated and found to be in
good condition. If damage has occurred during shipping, notify Applied Test Systems
and the carrier immediately. If it is necessary to le a damage claim, retain the packing
materials for inspection by the carrier.
B.2 After Sale Support
When you receive your equipment, copy your data label information onto the data
label template below (Figure B.1). Doing this will ensure you will have the appropriate
information for your records.
If you have any questions concerning the operation of your unit, contact your sales
representative. Before calling, please obtain the serial number from the unit’s data label.
Also, please be prepared to give a complete description of your problem.

C. Installation
C.1 General Installation
This section describes how to prepare your Applied Test Systems (ATS) furnace for
operation. Only perform the steps that apply to your specic furnace type. The installation
of the equipment must be performed by a qualied and licensed electrician in accordance
with National Electric code and local codes.
C.2 Positioning and Connecting
The following procedure describes how to position and connect an ATS Furnace that
is equipped with leg levelers. For furnaces that are mounted to a test machine or are
mounted using a test bracket, refer to appropriate mounting drawings.
1. Carefully remove the shipping crate and packing materials. Do not discard the packing
materials until all items on the invoice have been accounted for.
2. Position the furnace in the desired location.
3. If the unit did not come with a control system, skip to step 8 (p. 7).
4. The control system may or may not have a power cord supplied. If it does not, remove
the top cover of the control system to locate the power supply connection. To do this,
remove the two screws at the top of the back of the unit and slide the cover o toward
the back side. See Figure C.1 for screw location.
NOTE: Figure C.1 shows a typical control system. Not all control systems
will appear exactly the same.
