It is necessary to note thermal fatigue life by power cycle. Please reduce the temperature fluctuation range as much as possible when the

up and down of temperature are frequently generated.

¡

In case of forced air, ventilation must keep the temperature of point below the temperatures shown in Instruction Manual 7.
