clogged. The fan senses when this has occurred and
provides a warning as described in 3.6 under the
heading Operation/performance. The gas filters should
preferably be changed in accordance with a predetermi-
ned schedule. If no measurements are made on site, the
gas filters should be changed once a week or more fre-
quently if the pollutants can be smelt or tasted in the
head top.
Bear in mind that both filters/combined filters must be
changed at the same time and must be of the same type
and class. Proceed as follows:
