Warning
Do not use in flammable/explosive atmosphere
Do not use in flammable or explosive atmosphere.
As this system does not have an explosion-proof structure, it will cause a fire or explosion.
Do not use in a hot atmosphere
● The maximum allowable temperature for fan made by polyvinyl chloride or FRP is approximately
50 °C. Therefore, if it is used in a hot atmosphere, the fan blades may be deformed, which leads
to degraded ventilation performance or high noise level.
● If the working surface is lead-lined or made of epoxy resin, do not work directly on the surface or do
not heat the surface (for example, flowing hot water), because the surface may be damaged.
● The operating temperature of this product is 5 - 35 °C. Therefore, the atmospheric temperature in
the installation site must be maintained within 5 - 35 °C.
Do not use this product for experiments of perchloric acids
If a perchloric acid is used, the exterior and interior of this product may be corroded, which may cause
an explosion.
Do not use for radioactive materials
This product has not been designed to handle any radioactive materials.
Do not use for living beings
This product has not been designed to handle living beings (especially pathogens).
In case of fire
If a fire dumper is installed, it activates in case of fire not to allow the fume hood to discharge any air.
Always connect the grounding wire
Always connect the grounding wire properly, or electrical shock or fire may be caused.
Do not use the power cord with it tied in a bundle.
Bundled power cord may be heated, which may cause fire.
Do not damage the power cord
Avoid damage to the power cord by forcedly bending/pulling/twisting it. Otherwise, fire or electric shock
may be caused.
