    1. Safety Precautions Warning・Caution Warning Do not use this unit in an area where there is flammable or explosive gas Never use this unit in an area where there is flammable or explosive gas. This unit is not explosion-proof. An arc may be generated when the power switch is turned on or off, and fire/explosion may result.
  • Page 7 1. Safety Precautions Warning・Caution Caution When opening the cover... Make sure that the pressure of equipment has decreased to 0(zero) MPa before opening the cover. Generally the cover does not open due to the safety lock mechanism under the high pressure condition. The high-temperature and pressure vapor blows out if the cover is forced open under high pressure, which may cause a burn injury.
  • Page 8 1. Safety Precautions Warning・Caution Caution When taking the sterile samples from the chamber... Sufficiently remove the vapor inside the chamber before taking the sterile samples from the chamber. Wear heat-resistant leather gloves to take them from the chamber to protect your hands from high-temperature samples.
