1. Precautions
Under all conditions marked with
, it is necessary to consult the
document, so as to clarity the nature of potential risks and any
countermeasures that must be taken.
Actions or operations which are prohibited.
Actions or operations which must be followed
Make sure input voltage is correct and stable. The rated load of main power socket should be
higher than cabinet consumption. Plug must be well grounded.
In order to avoid air turbulence, the operator should slightly move his arms during
experiment. Hands should stay inside the working area at least 1 minute before operating. In
order to decrease the times of arms moving into and out of the working area, prepare all the
necessary items inside the cabinet before starting experiment.
Moving principles of different samples inside cabinet: When two or more samples need to be
moved, be sure that low-polluting samples move to high-polluting samples. Movement of
items should also follow the principles of slow-moving.
Samples placed in parallel: Samples should be placed in the cabinet parallel to avoid
cross-contamination between samples and blocking back air grille.
In order to avoid samples being sucked into the negative passage or the blower, do not place
soft and slight samples (for example: soft tissue) on the surface during experiment;
The weight of items placed in the cabinet should be no more than 23kg/(25×25cm

；
Avoid vibration: avoid using vibration equipment (e.g. centrifuges, vortex oscillator, etc.)
inside the cabinet. Vibration would cause lower cleanliness of operating area and affect
operator protection.
No flame: No flame is allowed inside the cabinet. Using of fire will lead to airflow disorder,
and filter damage. If sterilization is required during the experiment, infrared sterilizer is
highly recommended.
The UV lamp can only be turned on when the front window is closed and the fluorescent
lamp is off.When UV lamp working avoid looking straight.
