FACE SEAL REPLACEMENT
Both available versions of face seal (Standard and Flexi) have exactly the same plastic face
seal holder, so the replacing procedure is the same for both. In order to be able to observe
the details better, the assembly schemes will show the face seal holder without the face
seal (fabric part).
1. Remove the headgear in the oposite order as described in the section BH3 HELMET AND
HEADGEAR ASSEMBLY.
2. Pull the lower part of the face seal holder to release it from the airduct (1.).
3. Release the face seal holder from the two outside upper latches (2.).
4. Pull the face seal holder from the two inside upper latches (3.).
5. Take the new face seal and push the inner upper side of the face seal holder into the two up-
per inside latches (4.).
6.
Push the outside upper part of the face seal holder into the two outside upper latches (5.).
7. Slide the lower part of the face seal holder into the gap between the helmet and airduct (6.).
8. Assemble the headgear as described in the section BH3 HELMET AND HEADGEAR AS-
SEMBLY.

MOUNTING OF THE HOSE
Screw in the hose of PAPR (hose comes with
the Clean-air power unit set) as shown on the
scheme. Adjust the length of the hose between
the hose connector and the hose holder so you
achieve the maximum comfort. We recommend
this length to be 25-30 cm of non stretched hose,
so the upper loop would not be too long, as the
lenght should allow comfortable lifting of the
helmet. It is recommended that the length of the
hose from the hose connector to the Clean-air
power unit is adjusted, so that the hose follows
well the user's back without being stretched.
Once the hose is placed into the hose holder,
adjust the height of the hose by simply pulling the
hose trough the hose holder upward or down-
wards. Fine adjustment of shape of the loop can
be achieved by turning the hose left or right.
