Avoid poorly ventilated locations
This machine generates a slight amount of ozone, etc. during normal use. Although sensitivity to ozone, etc.
may vary, this amount is not harmful. Ozone, etc. may be more noticeable during extended use or long
production runs, especially in poorly ventilated rooms. It is recommended that the room where the machine
operates be appropriately ventilated to maintain a comfortable working environment. Also avoid locations

Do not install in a location where condensation occurs
Water droplets (condensation) may form inside the machine when the room where the machine is installed is
heated rapidly, and when the machine is moved from a cool or dry location to a hot or humid location. Using
