PRECAUTIONS FOR USING QUICK-FILL SYSTEM
1. The Quick-Fill System can only be used to fill approved air
mask cylinders.
2. The Quick-Fill System is not to be used as a "Buddy
Breather" such that two users are sharing the air supplied
by one air mask cylinder simultaneously doing so will
result in a non-approved NIOSH configuration.
3. The user is responsible for the air supply, which must meet
the requirements of Compressed Gas Association
Specification ANSI/G-7.1, Quality Verification Level (Grade)
D Gaseous Air or better, with a moisture dew point of not
greater than -65°F (24ppm water vapor, normal). In fire ser-
vice applications, MSA recommends breathing air quality
in accordance with NFPA 1989. Pressures at the inlet of the
Quick-Fill hose must not exceed that of the air mask (2216
psi or 4500 psi).
4. The user also is responsible for connecting the Quick-Fill
hose to an appropriate secondary air supply.
5. The cylinder must be inspected for damage before charg-
ing.
6. If filling cylinders in fresh air using the Quick-Fill System,
topping off the cylinder is recommended after the cylinder
has cooled from initial fill. Topping off a cylinder after it
has cooled will ensure proper service time.
DO NOT use the Quick-Fill System as an EBSS or "Buddy
Breather" such that two users are sharing the air sup-
plied by one approved air mask cylinder simultaneously.
The Quick-Fill hose assemblies and fittings are designed
to be used with Quality Verification Level (Grade) D or
better air as defined by ANSI/CGA G-7.1.TRANSFILLING
AIR FROM A SECONDARY AIR SUPPLY. In fire service
applications, MSA recommends breathing air quality in
accordance with NFPA 1989.
DO NOT lubricate the Quick-Fill fittings.
DO NOT permit oil, grease, or other contaminants to
come in contact with the Quick-Fill fittings.
Misuse can result in serious injury or death.
DO NOT use the Quick-Fill System or URC Assembly if there
is any possibility that the environment contains a CBRN war-
fare agent. These air mask accessories are not approved for
use in atmospheres containing CBRN warfare agents. Misuse
can result in serious injury or death.
The Quick-Fill System must be used only by qualified, trained
personnel who have carefully read and understood these
instructions, cautions, and warnings. NIOSH approvals of SCBA
from MSA are maintained while transfilling air ONLY if appropri-
ate Quick-Fill hose assemblies from MSA are used. Quick-Fill
hose assemblies and fittings are rated for a maximum working
pressure of 4500 psi.

WARNING
WARNING
NIOSH approval is maintained only when using the following
hose assemblies: 485331, 802687, 802688, 802689, 802690,
and 48332, for filling cylinders in IDLH atmospheres.
FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM
A secondary air supply stores compressed breathing air until
needed to refill air mask air cylinders. When transfilling, the
secondary air supply pressure must be greater than air mask
cylinder pressure. Examples of air supply includes: cascade air
cylinder refilling systems; high pressure compressor systems
with a fixed reservoir or a portable air system such as the MSA
RescueAire™ System.
The following hoses can be used to connect to a secondary air
supply.

1. To connect the Quick-Fill hose to the secondary air supply.
a. Turn the air supply on.
If there are leaks from either female fitting, or along the
hose, depressurize the hose and correct the problem. Such
leakage can result in increased fill time.
2. Attach the Quick-Fill hose to the shoulder mounted Quick-
Fill fitting.
