QUICK-FILL SYSTEM OPERATION
The Quick-Fill System may be used for transfill operations
as described in this manual. Standard operating proce-
dures should be developed for use of the Quick-Fill
System, unless using a 3000psi URC Assembly. The
3000psi URC Assembly cannot be used with Quick-Fill
system.
The 3000psi Operating System is NOT compatible with
a 2216psi SCBA Cylinder. Failure to follow the above
warnings may result in serious personal injury or
death.
DO NOT use the Quick-Fill System with 3000psig cylin-
ders. Failure to follow the above warnings may result
in serious personal injury or death.
An air mask using the 3000psig URC Assembly with-
out Quick-Fill System can receive (be a Receiver)
cylinder pressure through the 3000psig URC
Assembly. Do not use air mask with Quick-Fill System
and 3000psig URC Assembly on the same air mask.
Air mask with Quick-Fill System and 3000psig URC
Assembly on same air mask will not allow the relief
valve in the 3000psig URC Assembly to open as
designed. Failure to follow the above warnings may
result in serious personal injury or death.
The Quick-Fill System is not to be used as a "Buddy
Breather" such that two (2) users are sharing the air
supplied by one (1) approved SCBA cylinder simulta-
neously; doing so will void NIOSH approval. Failure to
follow the above warnings may result in serious per-
sonal 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 trans-
filling air ONLY if appropriate Quick-Fill System hose
assemblies from MSA are used. Quick-Fill System hose
assemblies and fittings are rated for a maximum working
pressure of 4500psig.
NIOSH approval is maintained only when using the follow-
ing hose assemblies:
485331, 802687, 802688, 802689, 802690, and 48332, for
filling cylinders in IDLH atmospheres.
For transfilling operations using the Quick-Fill System,
do not use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
Quick-Fill System. Use of any other transfilling hose
assembly and/or fitting may result in serious personal
injury or death, and will void NIOSH approval. Failure
to follow the above warnings may result in serious
personal injury or death.
DO NOT Transfill (be a Donor) using a 3000psi URC
Assembly. The 3000psi URC Assembly has a Check
Valve that does not allow cylinders to Transfill (be a
Donor). Using the 3000psi URC Assembly to fill cylin-
ders, the cylinder can only be filled to 2216psig. If the
pressure exceeds 2216psig a relief valve in the URC
Assembly will vent at approximately 2525psig or as
low as 2400psig. A 3000psig cylinder can only be filled
to 3000psig by using a secondary air source; the
3000psi URC Assembly cannot be used for filling a
3000psig Cylinder. Failure to follow the above warn-
ings may result in serious personal injury or death.
DO NOT lubricate the Quick-Fill fittings. Do not permit
oil, grease, or other contaminants to come in contact
with the Quick-Fill fittings. The Quick-Fill hose assem-
blies and fittings are designed to be used with Quality
Verification Level (Grade) D or better air as defined by
ANSI/CGA G7.1. TRANSFILLING AIR FROM A SEC-
ONDARY AIR SOURCE. Failure to follow the above
warnings may result in serious personal injury or
death.
A secondary air source stores compressed breathing air
until needed to refill SCBA air cylinders. Secondary air
source pressure must be greater than air mask cylinder
pressure. Examples of air sources include: cascade air
cylinder refilling systems; high pressure compressor sys-
tems with a fixed reservoir; and an SCBA air cylinder
which is not installed on an SCBA.
DO NOT connect a Quick-Fill System equipped Low
Pressure SCBA to an unregulated secondary air
source with a pressure greater than 2216psig. The
Quick-Fill System equipped low pressure air mask is
rated for a maximum working pressure of 2216psig. As
an additional safety feature, the SCBA has a pressure
relief valve which automatically vents at 2525psig.
Failure to follow the above warnings may result in
serious personal injury or death.
