Operation - MSA PremAire Cadet Escape Operation And Instructions Manual

Thoroughly inspect this respirator on receipt and before
use. This respirator is to be used only by trained and
qualified personnel. Read and understand these instruc-
tions before attempting to use this equipment.
AIR SOURCE
The purity of the air supply is the responsibility of the user.
The respirator is approved only when the air supplied
meets the requirements of the Compressed Gas
Association Specification G-7.1 for quality verification
level (Grade) D air or equivalent specifications.
AIR SUPPLY HOSE
The PremAire Cadet Escape Respirator can be used with
a wide range of MSA air supply hoses with a minimum
length of 8 feet and a maximum length of 300 feet. The
minimum air supply pressure is 70 psig and the maximum
air supply pressure is 90 psig. A maximum of 12 sections
of straight or uncoiled 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 8 feet to 100 feet lengths. The air-line connec-
tion to the apparatus is to be made through approved
quick-disconnects only.
MSA air supply hoses have temperature limitations.
DO NOT use the PremAire Cadet Escape Respirator
whenever ambient or inlet-air temperatures exceed
the limits specified below for each hose material.
Failure to follow this warning can result in serious per-
sonal injury or death.

SUPPLY HOSE–TO–SUPPLY HOSE CONNECTIONS
Use MSA-approved couplings only for supply hose con-
nections.
Hoses must only be interconnected with either the
threaded connector (3/4-16 UNF) or locking quick-dis-
connect couplings listed below. DO NOT use non-
locking quick disconnects to interconnect air supply
hoses.
3/4" - 16 UNF
Air-Supply Hose
This typical threaded connector method can be used to interconnect sec-
tions of approved air-supply hose to the PremAire System.
