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.

(5) Door open LED – Indicates that the door is open. LED turns “ON” when the door is

open

(6) Over heating alarm LED – Indicates that overheating has been triggered. LED blinks

while emitting an audible sound, when heater rises higher than the set temperature.

When the oven overheats power is cut to the temperature controller. To resume

operation set the knob 15% higher than the set temperature and press Start/Stop

button.

additional menus and settings of the TEMP button.

(5) Additional function of button

(1) A maximum of three preset values may be

stored in location slot SV.1, SV.2 and SV.3.

Press button twice access SV.1 (Set

Value 1). To change the value in SV.1, use

and arrow to increase or decrease to

desired set value, and then press (enter)

button. From the home LED display, press

the button three times to access SV.2

or four times to access SV.3.

(2) From the home screen press the five

times to select the desired temperature unit
