capacity.

Electric capacity: IN603: 100V AC 10A, IN803: 100V 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

• Never use explosive substances, flammable substances and substances that include
explosive or flammable ingredients in this unit. Explosion or fire may occur.

Flammable

or explosive

substance

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.

Samples

15Kg

Shelf

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.

Make the free space of 30% or more

7

Before Using this unit

Defrost in Refrigerator

Much frost on the evaporator degrades the refrigeration capability, which may cause
uncontrollability of setting temperature. In the IN602 or IN802, the condition of frost on the
evaporator can be checked through the frost inspection window inside furnace. The frosting speed
varies depending on the following conditions.

1) Temperature used･･････････････Easily frosted when using the unit in low temperature

2) External temperature/humidity･･･Easily frosted when external temperature/humidity is higher

3) Sample in furnace･･････････････Easily frosted when sample contains much water

The following operations can be set to take measure against frosting in the IN603 or IN803. Set
either of them depending on the situation. The fixed temperature and program operation are
available there by pressing the DEFROST key on the operation panel, in addition to the program
operation.

① Manual defrost operation (manual start/automatic stop):

Perform the defrost operation if much frost is in the evaporator. Temperature control is suspended in
addition to stop of heater and blast fan during operation. The operation is started manually and
stopped automatically with the built-in timer after 5-minute operation.

→Refer to the page 46 for the operating instructions.

② Cycle defrost operation (Automatic start/stop):

Set the cycle defrost operation to operate the unit effectively for long term. The unit can repeat the
defrost operation and operation stop automatically at specified interval specified previously. Frost
can be usually removed to perform the cycle defrost operation for ten minutes in a day. The amount
of frost varies depending on the conditions. Set it appropriately. Temperature control is suspended in
addition to stop of heater and blast fan during operation.
→Refer to the page 47 for the operating instructions.

CAUTION!

• The temperature in furnace increases about 3℃ at the defrost operation. Be careful if it affects the
samples. The indicated temperature may increase more than 10℃ at that time.

③ Setting of refrigeration operation mode in refrigerator (continuous/cycle):

Generation of frost can be reduced by setting the cycle operation where the refrigerator repeats
operation and halt. The refrigerator operation mode has a function to set the refrigerator to
continuous operation, cycle operation or halt condition. The refrigerator repeats 12-minute operation
and 12-minute halt condition in the cycle operation. If the setting temperature is 10℃ or below, it
switches automatically to the continuous operation related to the refrigeration capacity. The
refrigerator does not work regardless of setting temperature if it is set to be stopped. Set the
continuous operation when considering the accuracy of temperature control important, and set the
cycle operation when reducing the mount of frost at long term operation (the accuracy of temperature
control lower than that in the continuous operation). The cycle operation can also prevent the
samples from drying. Set the refrigerator stop if it is not necessary to be operated (it automatically
stops if the setting temperature is 44℃ or above).

→Refer to the page 49 for the operating instructions.

CAUTION!

• The frosting amount varies depending on the conditions in use even the cycle operation is set. It may
be larger when operating the refrigerator for long term. In this case, defrost the refrigerator by
performing the defrost operation or cycle defrost operation.

Notes for the independent overheating prevention device

• In case there is a small difference between the set values of temperature for the independent
overheating prevention device and that of controller, the independent overheating prevention
device may be activated and stops the operation. Set the temperature of the device so it be
at least 10℃ or more higher than that of controller.

• The default value of the independent overheating prevention device at factory shipment is
60℃. The setting temperature range is 0 to 65℃.

• The independent overheating prevention device is not intended to protect the sample from
overheating.

• For the independent overheating prevention device to start at the required temperature, first
establish a stable operation at such a required temperature, and lower gradually the setting
value of the independent overheating prevention device, and then check if the operation is
maintained with stable at the required temperature. (It takes about five soconds for the device
to activate. Check after waiting for five seconds.) When the device activates, the unit
indicates Er07 and stops the operation.

• Wait for about five seconds for the period to record it before turning off the power after the
setting temperature of independent overheating prevention device is changed.

Handling Precautions

WARNING!

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.

Substances that cannot 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 63 "List of
Dangerous Substances".)

CAUTION!

Do not step on this unit

Do not step on this unit. It will cause injury if this unit fall down or break.

Do not put anything on this unit

Keep clear on the unit to prevent dropping and injury. Do not put flammable such as paper
around it.

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.

About the amount of samples

If the excessive amount of sample is set, it could be impossible to control the temperature
normally. To keep the temperature control accuracy, do not use this unit in overload.

Recovering after power failure

When power is supplied after a power failure, the device automatically starts operation again with
the same state as just before the power failure.

When I used a backup power supply for blackout return, but a blackout occurred for need in less
than 30 minutes more than 30 minutes as for the charge time of the backup power supply since I
turned on electricity in a device, there is the thing that a blackout does not return temporarily. The
blackout return function operates normally after it was charged a backup power supply enough
because I am not abnormal.
