ENGLISH
Insert the oval end of the motor housing into the opening of the filter/cartridge sleeve. As you pull
the end of the filter/cartridge forward from the inside, seat the motor housing in the oval inlet. For HE
filters AS-140-5, ensure that the dashed line remains exposed just above the rim of the oval inlet (but
not more than 1/8 in [3.2 mm] above) after the motor housing is in place. For HF cartridges AS-176,
approximately 1/2 in [12.7 mm] of the sleeve should remain above the rim of the oval inlet. Also
ensure that the location lug on the motor housing engages with the slot in the back of the headgear.
Engage the spring clip to retain the motor housing (Fig. 7 and 8).
Use of excessive force during the insertion of the filter/cartridge may damage the filter/cartridge
and/or the filter/cartridge holder. Do not attempt to repair or use damaged filter/cartridges. If
damage is suspected, remove and start over with new components as necessary. Failure to do so
may adversely affect respirator performance and may result in sickness or death.
A user inspection and performance check must be performed prior to each use to verify that
the filter and blower assemblies have been correctly installed. If the respirator fails any of the
requirements of the user inspection and performance check, refer to the “Troubleshooting” section
in these User Instructions. Do not use the respirator until all necessary repairs have been made and
the respirator passes the performance check. Failure to do so may adversely affect respirator
performance and result in sickness or death.

WARNING
WARNING
The faceseal must be changed if it becomes torn, worn excessively or the elastic is
stretched-out. Exposure to solvents and/or ultraviolet light may accelerate the degradation of the
elastic. This could result in exposure to airborne contaminants and could result in sickness
or death.
Removal
Raise the visor surround to the horizontal position. Hold the headband away from the temple seals, and
unhook and pull the elastic loops from the headband. Remove the faceseal from each of the studs, and
unhook the center elastic loop from the lug on the front of the visor surround (Fig. 9 - 12).
Replacement
Attach the Tychem® QC faceseal to the visor surround as follows: hook the center elastic loop over the
lug at the front center of the visor surround. Fit each of the holes along the edge of the faceseal over
each of the studs on the visor surround.
Attach the faceseal to the headband as follows: turn the headgear assembly upside down, with the
visor facing away from you. Pull one of the larger loops on the faceseal down over the inside of the
headband and secure it over the headband lug. Push the part of the loop closest to you down between
the headband and the edge of the headgear assembly, securing it over the same headband lug. Repeat
for the other loop (Fig. 13 and 14).
