Safety Information
Safety Precautions
Warning precautions alerts for possible situations of
personal injury.
Caution precautions alerts for possible damage to
equipment
These instructions contain important operating and safety information. The user must carefully
read and understand the instruction manual provided, prior to operation of unit. The unit has been
designed for optimal function, reliability, safety, and ease of use. It is the user’s responsibility to
install the oven in conformance with local electrical codes.
Do not use the unit in areas where flammable or explosive gasses are present. This
unit is NOT explosion-proof. To avoid possible fire and/or property loss, and injury
or death to personnel, do not place oven on or near any combustible surface.

Installation
Do not use this unit is areas where flammable or explosive gasses are present. This
unit is NOT explosion-proof. Do not place oven on or near any combustible
surface to avoid the possibility of fire and resulting property loss and injury or death
to personnel.
Do not use explosive and/or flammable substances that include explosive and/or
flammable components. Not adhering and not following these precautions may
result in explosions or fires.
Do not place sample(s) on the floor of the chamber. There is a possibility that the
sample(s) overheat and catch fire.
The unit must be connected to a power source that meets the electrical
requirements as specified on the unit’s nameplate.
Use power supplies that are grounded. Ungrounded power may cause serious
damage to the user and equipment. For safety, do not connect any ground
conductor to a gas or water pipe.
(1) Open the package carefully. Make sure all parts are accounted for before discarding
packaging materials.

b. Operating manual
c. Fuse
d. Shelf
e. Shelf guide
f. Lab Tracer software
g. RS-232 communication cable
(2) Install the unit on a flat level surface, free from drafts, and heat sources, to allow for natural
air movement to dissipate heat from the oven.
(3) Allow enough space to the left of the unit to allow for the door to open 180°.
(4) Avoid heat sources and direct sun light, place the unit where ambient temperature range is
5C ~ 40C and relative humidity is lower than 80%.
(5) Do not install unit in a danger zone, where there are flammable gases, explosive materials,
and organic solvents.
(6) The unit will only work correctly, when using proper power supply.
(7) Outlets should be located near the unit and easily accessible.
(8) Do not allow moisture, organic solvents, dust, and/or corrosive gas to enter into the control
box.
(9) Do not install unit near other machines generating strong high frequency noise.
Notice
(1) Do not touch power cord and/or other electrical components with wet hands.
(2) Do not place explosive and/or flammable chemicals inside of the oven.
(3) Do not place flammable materials near oven.
(4) Use caution when handling samples inside of the oven. Samples will be hot to the touch
during or after testing runs.
(5) When cleaning the unit, do not pour water directly on it.

Controller
Specificity
(1) CLS-Control System temperature and heater output are controlled by the Main CPU. The
Main CPU is able to perform precise PID calculations. All safety control for is controlled
by the selective functional Logic IC, which is installed separately. It is designed to
conduct safety performance against any electric and/or electronic shock on the unit.
(2) CLS-Control System shuts down all 2 phase power supply to each component
immediately and informs user of instability through audio and visual device, and then
keeps in safe mode until all instability conditions have been resolved.
(3) CLS-Control System provides users with two choices when the unit operation are
terminated by power failure and then recovered; the first choice allows for operation of
unit to resume and the second choice allows for the unit to keep at standstill.
(4) CLS-Control System is designed to keep very small amount of currency (only 5V, 10mA)
to contact point. This allows for extended durability at the contact point.
Name and operation
(1) HEATER LED – Indicates that the heating function is “ON”
(2) Auto Tune LED – Indicated by flickering when Auto-tuning (self calibration feature) is in
operation.
(3) Wait On Timer LED - Indicates operation delay start time. LED blinks when the timer is
activated and off when the timer is deactivated.
(4) Wait Off Timer LED - Indicating operation delay stop time. LED blinks when the timer is
activated and off when the timer is deactivated.
