◆Before the experiment starts, it must be confirmed that the fume hood should be in operation before the experiment operation can be carried out.
◆Continue to run for at least 5 minutes before the end of the experiment before turning off the ventilator to discharge the residual gas in the pipeline. Consider installing an exhaust time delay device to ensure that the fan runs on a delayed basis.
◆ During the experiment, do not put any equipment within 150mm from the glass window. Large-scale experimental equipment should have sufficient space and should not affect the air flow. The front window should be closed as much as possible.
