Nilfisk-Advance America GB 1133 - Manual (Page 8)

7 Filters and emptying systems
The installed main and exhaust filters are approved by the German Trade
Association Institute for Safety at the Workplace (BIA). The transmission factors are
lower than the limiting values required by relating regulations.
The installed filters normally have a long service life. Exchange of filters should only
be carried out by Nilfisk-Advance Service.
Without the appropriate emptying system, the machine does not match the
requirements specified by relating regulations. In this case, danger to health
cannot be excluded.
