WARNING!
If there is leakage from either female fitting or anywhere along the emergency transfill hose, discon-
nect the female fittings and return to fresh air immediately.
Failure to obey this warning can result in serious injury or death.
(1) Remove the emergency transfill hose from its protective
pouch.
(2) Remove the rubber dust cap from both female fittings on the
emergency transfill hose.
(3) Remove the rubber dust cap from the male inlet fittings on
the UAC fittings on both SCBAs.
(4) Push the female fitting of the Quick-Fill hose onto the male
fitting of the UAC until the hose clicks into position.
(5) Pull on the emergency transfill hose to make sure the
connections are secure.
When both female fittings are fully engaged with the UAC
fittings, filling starts immediately.
After approximately 60 seconds, the pressure between the
donor and receiver SCBA cylinders will be equal.
(6) To disconnect the emergency transfill hose from the SCBA,
pull the gray sleeve back on both ends.
The hose fittings and the UAC fittings will separate.
A hissing or popping sound may occur as the fittings sepa-
rate and the high-pressure air is sealed off.
(7) Immediately install the rubber dust cap on the UAC fitting to
make a redundant seal and prevent dirt, water, and debris
from going into the fitting.
