Cautions in Using with Safety
Fundamental Matters of "WARNING!" and "CAUTION!"
WARNING!
Do not use this unit in an area where there is flammable or explosive gas
Never use this unit in an area where there is flammable or explosive gas. This unit is not
explosion-proof. An arc may be generated when the power switch is turned on or off, and
fire/explosion may result. (Refer to page 61 "List of Dangerous Substances".)
Always ground this unit
Always ground this unit on the power equipment side in order to avoid electrical shock due to a power
surge.
If a problem occurs
If smoke or strange odor should come out of this unit for some reason, turn off the power key right
away, and then turn off the circuit breaker and the main power. Immediately contact a service
technician for inspection. If this procedure is not followed, fire or electrical shock may result. Never
perform repair work yourself, since it is dangerous and not recommended.
Do not use the power cord if it is bundled or tangled
Do not use the power cord if it is bundled or tangled. If it is used in this manner, it can overheat and
fire may be caused.
Do not process, bend, wring, or stretch the power cord forcibly
Do not process, bend, wring, or stretch the power cord forcibly. Fire or electrical shock may result.
Substances that can not be used
Never use explosive substances, flammable substances and substances that include explosive or
flammable ingredients in this unit. Explosion or fire may occur. (Refer to page 61 "List of Dangerous
Substances".)
Do not touch high-temperature parts
The inside of the body or the door may become hot during and just after operation. It may cause burns.
CAUTION!
During a thunder storm
During a thunderstorm, turn off the power key immediately, then turn off the circuit breaker and the main
power. If this procedure is not followed, fire or electrical shock may be caused.

Before Using this unit
Requirements for Installation
WARNING!
1. Always ground this unit
•Be sure to connect the earth wire (the green cable of power cord) to the grounding conductor
or ground terminal to prevent accidents caused by electric leakage.
•Do not connect the earth wire to gas or water pipes. If not, fire disaster may be caused.
•Do not connect the earth wire to the ground for telephone wire or lightning conductor. If not,
fire disaster or electric shock may be caused.
•Do not use a branching receptacle, which may cause the heat generation.
2. Choose a proper place for installation
•Do not install this unit in a place where:
♦Rough or dirty surface.
♦Flammable gas or corrosive gas is generated.
♦Ambient temperature exceeds 35°C.
♦Ambient temperature fluctuates violently.
♦There is direct sunlight.
♦There is excessive humidity and dust.
♦There is a constant vibration.
•Install this unit on a stable place with the space as shown below.

5. Do not modify 6. Installation on horizontal surface
•Modification of this unit is strictly
prohibited. This could cause a failure.
•Set this unit to the flattest place. Setting
this unit on rough or slope place could
cause the vibration or noise, or cause the
unexpectible trouble or malfunction.

Before Using this unit
Requirements for Installation
7. Choose a correct power distribution board or receptacle
•Choose a correct power distribution board or receptacle that meets the unit’s rated electric
capacity.
Electric capacity: IN602CS: 115V AC 12A,
NOTE)
Starburst connection with a branching receptacle or extended wiring with a cord reel lowers
electrical power voltage, which may cause the degradation of the refrigeration capability or
temperature control performance.
8. Handling of power code
•Do not entangle the power cord. This will cause overheating and possibly a fire.
•Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire
and electrical shock.
•Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to
prevent it from being damaged and to avoid a fire or electrical shock.
•Keep the power cord away from any heating equipment such as a room heater. The cord's
insulation may melt and cause a fire or electrical shock.
•If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off the
power at the rear of this unit and shut off the main supply power. Then contact your nearest
dealer for replacement of the power cord. Leaving it may cause a fire or electrical shock.
•Connect the power plug to the receptacle which is supplied appropriate power and voltage.
9. Before/after installing
•It may cause injure to a person if this unit falls down or moves by the earthquake and the
impact. etc..To prevent, take measures that the unit cannot fall down, and not install to busy
place.

Before Using this unit
When Using the Unit
CAUTION!
1. Do not use explosive or flammable substance
•Never use explosive substances, flammable substances and substances that include
explosive or flammable ingredients in this unit. Explosion or fire may occur.
2. Do not make an overload 3. Do not set samples in close formation
•The withstand load of shelf is 15kg
（uniform load）Set the samples apart
each other.
•The temperature in furnace cannot be
controlled if too much samples are set
there. Make sure to use the shelf and
set samples apart each other so as to
make the free space of 30% or more to
the furnace to acquire accuracy of
temperature.
Make the free space of 30% or more
4. Notes for some kind of sample
•Stainless steel SUS304 is used for interior; however, it may be corroded by strong acid etc.
And the door packing made of rubber may be corroded by some kind of solvent, e.g. alkaline,
oil, halogen etc.
•Much frost on the evaporator degrades the refrigeration capability, which may cause
uncontrollability of setting temperature. Be careful, especially, to treat samples with large
water content that generate much frost. Perform the defrost operation if frost is observed
through the frost inspection window.
•The equipment with large heat load cannot be used because the temperature in furnace
increases.
