will proceed to the next step once the set temperature is reached within the set time.
※ When a fixed temperature step is set and wait is [ON], the wait mode will continue from the time
when the temperature in the chamber drops below the lower limit of the wait width deviation
temperature due to, for example, opening of the door until the temperature in the chamber will
recover above that lower limit. At [OFF] the process will proceed to the next step after the set time
irrespective of changes of the temperature in the chamber.
※ When you use the repeat function, program the operation so that the set temperature before shifting
to the repeat mode will be the same as the set temperature of the destination of repetition.
※ Checking the heating capacity and the cooling capacity before setting is encouraged since these
will differ depending on the environmental temperature and the operating conditions.

When the wait function is set to [ON], the mode will remain “waiting” without counting down the time until
temperature in the chamber (indication) will be within the wait deviation range between -3℃ and +6℃
to the set temperature. When you set the set time to 0 minute, the unit will operate from the “Start
temperature” to the “Set temperature” at full power.
When you have set time longer than the specified performance, the unit will control heating and cooling
so that the set temperature will be attained (within the wait width deviation range) at the set time.
Even when the indicated temperature drops while temperature is stable due to opening of the door, the
mode will remain “waiting” without counting down the time if the wait width upper or lower limit is
exceeded.
When you set the wait function to [OFF], the unit will proceed to the next step at the set time irrespective
whether the temperature is within the wait width deviation between the set temperature and the
indicated temperature.
When the set time is set to a short time exceeding the heating and cooling capacity, the unit will proceed
to the next step before the set temperature is attained and you need to make sure that the wait function
is set at [ON] when you are going to operate at the full power.

Never set samples on bottom of Chamber. If samples will be processed at setting on bottom of
it, this Equipment may be not given as its full performance and become high temperature unlikely
and also cause failure.
Set samples on attached shelves properly installed on their brackets.
Do not allow samples to contact directly to side walls of Chamber.
Do not process humid specimens.
Water condensed inside the unit may cause an electric shock, a malfunction of the unit or
deterioration of HEPA filter.
Do not attempt to process wet samples.
The unit employs blowing to improve temperature distribution inside the chamber. When
processing powder or small samples, make sure that the sample will not scatter. A fire or an
electric shock may result if a flammable or a metal object enters the heater.
When processing smaller specimens, you can minimize circulating wind amount in the bath by
setting the variable wind speed to low, in which case the temperature performance will be out of
the warranty and the user needs to confirm the temperature characteristics.
Heating may take some time when the amount of samples is large or when processing samples
with a larger heat burden. Check the appropriate amount as necessary and set the sample. Also
note that the temperature indication may be unstable when processing heat-generating samples
(note that sample itself must be free of fear of explosion, inflammation or ignition).
Be aware of temperature sensor which it is installed on Chamber inside right portion and control
Chamber temperature. Therefore, if the amount of specimen is large or the equipment is in the
middle of heating, sensor detected temperature may not agree with temperature of the samples.
In particular, actual Chamber temperature will differ greatly from Read Temperature displayed on
Controller, right after opening or closing of this Equipment Door.
When a gap occurs between the temperature in the bath and the measured temperature requiring
adjustment, compensate temperature by referring to “P.39 Setting a calibration offset”.
When operation stopped from a power failure and then power recovers, the unit will automatically
resume operation.
See “P.40 Setting the recovery mode” for details.
Must be set temperature of Independent Overheat Prevention Device (IOPD).
Note that temperature of this IOPD must be set to temperature over 20℃ higher than Target
Temperature.
Refer to Chapter 4. Operating Procedure –“Independent Overheat Prevention Device” for how to
set and other cautions on page 46.
5. Handling precautions
8.Never set samples on bottom of Chamber.
9. Do not process humid or wet specimens.
10. Take care for processing of powder and small samples.
