Handling Precautions
Do not use corrosive sample
Stainless steel SUS304 is used for interior; however, it may be corroded by strong acid etc. And
the door packing made of silicon rubber may be corroded by some kind of solvent, e.g. alkaline,
oil, halogen etc. Do not use the sample includes those.
Use under proper temperature range
Operational temperature range of this unit is 0 to 60℃. Never set the temperature out of that.
Setting of sample
Since the withstand load of the attached shelf plate is about 10kg per one plate, do not set
heavier sample than 10kg. When setting several sample, set them as dispersed as possible.
Too much sample setting could cause the improper control of the temperature. For keeping the
proper temperature, keep more than 30% space against whole size of the shelf plate, and set the
sample. The unit has a capability of cooling the samples to 0℃ under the condition of ambient
temperature 23℃ without load. The minimum achievable temperature may vary depending on
the amount of samples and degree of contamination on the fan or filter.
Do not put sample on the internal base
If sample is put directly on the base, device performance will be disturbed. Furthermore, internal
temperature will abnormally rise and it will cause trouble. Never put sample on the base. Fix the
shelf on the bracket then set sample on it.
