installing Breathing tube assembly
in Hoods (20Bt or rtBt)
1. Remove nylon clamp from plastic anchor plate on hood (see
Figure 9). Do not remove foam from inside the breathing tube,
used with CC20 Series Airline Respirators. The foam helps
reduce the noise level of incoming air.
2. Insert the open end of the breathing tube approximately five
inches into hood’s air entry sleeve (see Figure 10).
3. Install nylon clamp over air entry sleeve and breathing tube,
inserting clamp locks through two holes in plastic anchorplate
that is sewn into hood. Locks should face away from user’s
neck (see Figure 11).
4. Engage clamp locks and squeeze together until tight.
5. For CC20 Series Airline Respirators, attach other end of
breathing tube to flow control device on belt by screwing nylon
hose connector on flow control device.
Note
Refer to PAPR manual for connection of breathing tube to
PAPR blower.
installing Breathing tube assembly
in Loose-Fitting Facepieces
1. The 20LFM, 20LFL, 20LF2S, 20LF2M and 20LF2L loose-fitting
facepieces have a sewn-in breathing tube connector on the
back. The 20LFBT breathing tube has a special connector on
the hood end with bayonet type pins.
2. Insert the bayonet connector of the 20LFBT breathing tube in
the hood connector and turn clockwise until it locks in place
(see Figure 12).
