19.3 Checking the humidity system fan
The user should regularly perform the following checks:
Hold a sheet of paper in front of the ventilation silts at the bottom rear of the unit. If the sheet of paper is
suctioned inwards, the fan operates correctly. When opening the door, the fan automatically turns off.
19.4 Gas inlet fine filter
When the unit is in operation, the incoming gas passes through a fine gas filter (aseptic filter, filtration
efficiency 99.99 %, particle size 0.45 µm).This fine filter prevents dirt accumulating in the gas inlet valves
and the tubes leading into the inner chamber, which could be in the gas cylinder or in the supply tubes.
When using gas with a technical grade of 99.5 %, we recommend changing the fine gas filter once a year.
Please consult BINDER Service. When using gases with less pureness, the changing intervals should be
shorter.
