Head Seal
Removal
Remove the cradle assembly as described above. The head seal is retained by three anchors, one at
each side and one in the center of the headgear. Lift the side lugs up from their headgear shell anchors
and remove the central lug from its aperture (Fig. 30).
Replacement
Insert the central lug into its aperture in the headgear shell. Slide both side lugs into their respective
headgear anchor positions. Ensure all three anchor points are properly connected so the head seal
remains in contact with the headgear.
Temple Seals
Removal
Remove the head seal as described above. Pull the temple seals away from the head seal. If
necessary, clean to remove any foam residue adhering to the head seal.
Replacement
Remove the protective covering from the self-adhesive side of the temple seals and press the seals
firmly against the head seal. Note that the temple seals have left and right orientations. Ensure they
are positioned properly against the head seal.
INSPECTION
An inspection must always be performed prior to each use of the respirator as follows:
1. Look for dents, scratches, cuts, or discoloration in the headgear shell and other components;
2. Check that the visor is properly installed in the visor surround, secured at all 12 lug positions;
3. Check that the faceseal is properly fitted onto the visor surround;
4. Check that the temple seals and head-seal are properly installed and in good condition;
5. Check that the high efficiency filter is correctly installed;
6. Use a freshly charged battery.

Impact to the headgear may weaken the shell and/or suspension system and reduce head
protection from subsequent impact, even if there is no visible damage. If the headgear shell has
been subject to impact or if other damage to the headgear is suspected, the headgear shell and
suspension system must be replaced. Failure to do so may result in serious injury or death.
Failure to conduct an inspection and complete all necessary repairs before use may adversely
affect respirator performance and result in sickness or death.
USER PERFORMANCE CHECK
Each time the respirator is put on, perform the following user performance check to ensure proper
airflow. If any components are missing or damaged, replace them prior to using the system.
1. Open the outer grill (Fig. 31), remove prefilter (Fig. 32) and inner grill (Fig. 33). Switch the battery
pack on and ensure that the fan draws air through the main filter.
2. Holding the headgear upside down, place the airflow indicator over the round fan grill (Fig 34).
Ensure that the airflow indicator is not bent or damaged.
WARNING
3. Gently turn the headgear right-side up (Fig. 35). Sufficient airflow will retain the indicator in
position. If the airflow will not retain the indicator, replace the main filter/cartridge as described
in “Assembly” section. If an adequate airflow is still not maintained, refer to “Troubleshooting”
section in these User Instructions and do not use the unit.
4. Place the inner grill and the prefilter back into the motor housing and close the outer grill. Ensure that
the outer grill hinge is positioned in the recess at the rear of the motor housing assembly (Fig. 36).
