Quick-Fill Coupling

The Quick-Fill coupling is a male Quick-Fill inlet for use by Rapid Intervention Teams for emer-
gency filling operations. The system also includes an automatically resetting pressure relief valve.

12.1 Precautions

• The Quick-Fill coupling can only be used to fill approved SCBA cylinders.
• The user is responsible for the air supply, which must meet the requirements of of EN 12021.
• The user also is responsible for connecting the Quick-Fill hose to an appropriate secondary air
supply.
• The cylinder must be inspected for damage before charging.
• If topping off the cylinder using the QUICK-FILL coupling, it is recommended to wait until after
the cylinder has cooled from initial fill. Topping off a cylinder after it has cooled will ensure
proper service time.
WARNING!
DO NOT use the Quick-Fill coupling as a second man connection such that two users are

sharing the air supplied by one approved SCBA cylinder simultaneously.
The Quick-Fill coupling must be used by trained personnel only.

DO NOT lubricate the Quick-Fill couplings. Do not permit oil, grease, or other contaminants to

come in contact with the Quick-Fill couplings.
The hose assemblies and fittings are designed to be used with breathable air according to

EN 12021.
Misuse can result in serious injury or death.
NOTE: The Quick-Fill coupling may be used for transfill operations as described in this manual.
Standard operating procedures should be developed for use of the Quick-Fill coupling.

12.2 Filling Instructions

A secondary air supply stores compressed breathing air until needed to refill SCBA air cylinders.
When transfilling, the secondary air supply pressure must be greater than SCBA cylinder pres-
sure. Examples of air supplies include: cascade air cylinder refilling systems; high pressure
compressor systems with a fixed reservoir; or a portable air system such as the MSA RIT Bag.
WARNING!
DO NOT connect a high pressure SCBA to a secondary air supply with a pressure greater than
300 bar. The high pressure SCBA is rated for a maximum working pressure of 300 bar.
Misuse can result in serious injury or death.
(1) Connect the Quick-Fill hose to the secondary air supply.
(2) Turn the air supply on.
CAUTION!
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.
Attach the Quick-Fill hose to the Quick-Fill coupling:
(3) Remove the rubber dust cap from the male inlet fitting on the Quick-Fill coupling. Be sure that
the cylinder valve is fully opened.
(4) Remove the rubber dust cap from the female fitting on the Quick-Fill hose.
(5) Push the female fitting of the hose onto the male fitting of the Quick-Fill coupling until it snaps
in place.
