Surface Maintenance
Painted surfaces and the outside of the safety viewscreen may be cleaned with
soap and water. A light abrasive soap can be used on the stainless steel areas to
help remove scratches and stains. Rub in the direction of the grain only.
Use Of Ancillary Equipment
Do not use equipment requiring more than three (3) amperes maximum.
Bunsen Burner
Caution: Bunsen Burners should never be operated unless the cabinet blowers
are turned “ON.” The use of flammable materials within the cabinet is
not recommended. Bunsen Burners must be operated so as to prevent
unburned gas mixture collection in the cabinet.
If a flame is required within the work area, a small "touch-light" type should be used
to minimize heat build-up and subsequent operator discomfort that a continually
burning flame may create. To avoid exposing an open flame within the work area,
an incinerator-type sterilizer is recommended for sterilizing inoculating loops.
Blender
Caution: Be sure that the unit is operating before starting either a centrifuge or
blender. The cabinet must continue to operate for a minimum of five (5)
minutes after the appliance is turned “OFF.”
A blender may be operated in the unit. Because of the severity of the aerosol
generated, however, it is suggested that the operator keep his or her arms, other
equipment and containers out of the work area during this procedure.
