3. Use
3.1. Installing the filters
Attention!
The respiratory must be in perfect condition and suitable for the
intended use. Before installing the filters check:

that the filters are not damaged,

that the filters are suitable for the expected hazardous substances,

that 2 filters of the same type (model, filter class) are installed.

B
(1) Select the appropriate filter cap for the filters
required:

flat cap for particle or gas filters (figure A)

high cap for combined filters (figure B)
(2) Insert the filter in the OptimAir 3000 and screw the
cap down to clamp the filters in place tightening by
hand only.
3.2. Service Time
The service time of respiratory protective filters depends on the conditions of use.

The end of service time of gas filters can usually be detected by odour on
the clean side of the filter device. The filter must then be changed
immediately.

The end of service time of particle filters can usually be detected by an
increase in the flow resistance. In power assisted filtering devices the
minimum flow rate is not achieved and a warning signal and / or a visual
warning signal (red LCD) is activated. The filter must then be changed
immediately.
Attention!
When exchanging used filters both filters have to be replaced even if
only one of either of these appears to be at the end of its service time.
Sufficient respiratory protection is otherwise not guaranteed.
