QUICK-FILL SYSTEM OPERATION
lated training exercises. Both donor and receiver must
return to fresh air immediately following the procedure.
DO NOT transfill if the donor's audible alarm is ringing
or FireHawk M7 Responder HUD /FireHawk M7
Control Module are flashing. Failure to follow this
warning can result in shorter escape time to return to
fresh air, causing serious personal injury or death.
The audible alarm begins ringing and heads-up display
system begins flashing to indicate that the pressure in the
cylinder has been reduced to 25% of its rated working
pressure. Remaining service time must be used for
escape to fresh air. If the donor's audible alarm begins
ringing or FireHawk M7 Responder HUD/FireHawk M7
Control Module begins flashing during transfilling, the
donor should disconnect and preserve his escape time.
1. If the donor's alarm is not ringing or FireHawk M7
Responder HUD/FireHawk M7 Control Module are not
flashing and you have sufficient air to transfill air to a
receiver, (greater than 1000 psi for 2216 psi air masks
and greater than 2000 psi for 4500 psi air masks), fol-
low these steps.
a. Remove the 3 foot emergency transfill hose from its
protective pouch.
b. Remove the rubber dust cover from both female fit-
tings on the quick-fill hose assembly.
c. Remove the rubber dust cover from the male Quick-
Fill System fitting.
d. Push the female fittings on to the male fittings until
they click in place. Pull on the hose to be sure it
snapped in place.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Failure to follow this warning can result in seri-
ous personal injury or death.
e. After approximately 30-60 seconds, pressure
between the air mask cylinders will be equal.
f. Disconnect the quick-fill hose from the air mask by
pulling the gray sleeve back on both ends. A hiss or
pop may be heard as the fittings separate and the
high pressure air is sealed off.
g. Immediately install the dust cover on the quick-fill
male fitting. The dust cover prevents dirt, water, and
debris from entering the fitting, and acts as a redun-
dant seal.
QUICK-FILL SYSTEM STORAGE
1. Preparing the Quick-Fill System for storage:
a. Press in on the center of the quick-disconnect dust
cap to release any pressure in the quick-fill hose.
b. Roll up the hose and place it in its protective pouch.
