Filter or Cartridge Installation
•
Do not open the packaging until ready to install and use the filter or cartridge
Ensure that the filter or cartridge is installed correctly as show below:
1. Twist the filter in the direction 1 (counter-clockwise) to engage the thread and then
tighten in direction 2 (clockwise) to fit the filter on the respirator.
2. Take care not to cross thread the filter. 4 shows the correct gap between the filter and the
respirator once the filter has been installed. If the gap is uneven (as identified by 3), the
filter must be removed and reinstalled as it has been cross-threaded and will not
function correctly.
CAUTION
Do not replace filter with the unit running.
