14 ExtendAire II Airline Connection Operation
The ExtendAire II airline connection enables an SCBA equipped with ExtendAire II to be used as a
combination self-contained-breathing-apparatus and supplied-air-respirator. The ExtendAire II airline
connection attaches to the ExtendAire II manifold.
Air Supply
When used as a combination respirator, the respirator shall be supplied with respirable air through an
air supply hose assembly with a minimum length of 9.5 inches and a maximum length of 300 feet
within a pressure range of 70-110 psig. A maximum of 12 sections of straight or six coiled air supply
hose may be used in making up the working length of hose. When using coiled hose, a maximum of
six sections may be used and each section is considered to be 50 feet long. Hose sections vary from
9.5 inches to 100 feet lengths. The airline connection to the apparatus is to be made through
approved quick connects only. The purity of the air supply is the responsibility of the user. The respi-
rator is approved only with supplied air meeting the requirements of the Compressed Gas Association
Specification G-7 for quality verification level (grade) D air or equivalent specifications.
The ExtendAire II and ExtendAire II airline connection are NOT to be used in the hose section length
and quantity calculations.
See Approval Insert (P/N 10183896) for a listing of approved connections.
14.1 Installation of the G1 ExtendAire II Airline Connection
(1) Ensure system is not pressurized.
(2) Remove dust cap from G1 ExtendAire II manifold, attach
G1 ExtendAire II airline connection.
(3) Coil G1 ExtendAire II hose counter-clockwise, inserting
ExtendAire connection and G1 ExtendAire II assembly
into pouch.
(4) If the Combination SCBA/SAR Apparatus is to be used in
tandem with other users, feed ExtendAire II airline
connection through grommet in G1 Pouch (It may be
necessary to feed dust cap through separately).
This allows the connection to remain protected, but may
be difficult for a solo user to connect/disconnect.
