6.9 Working safely - Recommendations
6.9.1 Before start-up
The cabinets may only be operated at temperatures between 15
°
C and 35
°
C, at maximum
80% relative humidity, and at normal air pressure.
Approximately 15 minutes before any work in the cabinet, the fan of the unit must be
switched on at normal velocity.
The work chamber and the front- and side windows are to be carefully cleaned and
disinfected. Use an ethanol solution or similar. It is recommended to use special lint-free
material. Do not use explosive disinfectants.
Objects and appliances must be carefully cleaned or disinfected before being introduced
into the work chamber. Do not bring in writing utensils, packing material, etc.
The front window is positioned in working position and kept in that position during the entire
work process.
Necessary appliances for use during work must be placed within easy reach.
Secure the appropriate protection of the operator as well as the product (e.g. clothes,
gloves, etc.).
6.10 While working
Do not perform work while the fan is running at reduced speed.
The front window must be in work position.
Place the product behind the perforated area of the work surface.
Work with calm, smooth movements.
Never overload the work chamber.
Reduce the number of transfers into and out of the work chamber.
Avoid equipment with high heat emission.
Avoid a cabinet location where personnel frequently pass avoid draughts.
The efficiency of the laminar airflow in the work chamber is essential for product
protection. Negative influences of the flow conditions must therefore be avoided.
