3. Pre-Installation Check
• Ambient temperature must be 20 ± 10°C and humidity 30% to 80%. Any dew condensation
must be avoided.
• When the machine is transferred to another place and the ambient temperature rises more
than the surface of the machine, dew may condense under the condition described below.
Note that dew condensation may cause the machine to break down.
Condition of Dew Condensation
Dew may condense when the differences (based on "Humidity (%)") between the ambient
and surface temperatures of the machine reach the values or more in the table below.
