AUDI-LARM ALARM WITH URC ASSEMBLY
pop may be heard as the fittings separate and the
h
igh pressure air is sealed off.
g. Immediately install the dust cover on the URC fit-
t
ing. The dust cover prevents dirt, water, and debris
from entering the fitting, and acts as a redundant
seal.
URC ASSEMBLY LEAKAGE
1. When transfilling in fresh air and the dust cover will
not stay on the male fitting because air is leaking, cor-
rect the condition before using the air mask.
2. When transfilling in a contaminated atmosphere and
the dust cover will not stay on the male fitting because
air is leaking:
a. Immediately reconnect the quick-fill hose to seal off
the leak and return to fresh air.
b. If the hose will not reconnect, reach behind and
c
lose the cylinder valve. Air pressure in the regulator
will drop, and the leak will slow down.
c
. Quickly replace the protective dust cap on the male
fitting. This will form a redundant seal.
d. Open the cylinder valve and return to fresh air
immediately. The dust cover prevents dirt, water,
and debris from entering the fitting, and acts as a
r
edundant seal.
EMERGENCY TRANSFILL HOSE STORAGE
1. Preparing the Emergency Transfill Hose for storage:
a. Press in on the center of the quick-disconnect dust
cap to release any pressure in the transfill hose.
b. Roll up the hose and place it in its protective pouch.
