of damage to the facepiece port side of the nose cup where the
regulator attaches.

properly seated between the
flanges of the voicemitter

11. All SCOTT facepieces used with this respirator may be fitted with
a nose cup. Verify that the Nose Cup is properly installed for the
model of facepiece being used. A Nose Cup is standard on the
SCOTT AV-2000®, Weld-O-Vista, and AV-3000® full facepieces
and optional on the SCOTT-O-VISTA® full facepiece.
a) SCOTT AV-3000 and AV-3000 SureSeal Facepieces are avail-
able with two different styles of nose cup: a BLACK Nose Cup
which fits behind the face seal, and a GRAY Nose Cup which
fits in front of the face seal. The BLACK Nose cup must be fit-
ted BEHIND the Face Seal as shown in FIGURE 11. The GRAY
Nose Cup must be fitted IN FRONT OF the Face Seal as shown
in FIGURE 12.
b) The AV-2000, the Weld-O-Vista, and the SCOTT-O-VISTA, the
Nose Cup always goes BEHIND the face seal REGARDLESS
of the color of the nose cup. See FIGURE 13.
12. Verify that the facepiece is clean.
13. Adjust the head straps to the full outward position.
