b To reconnect, align the HUD plug with the mating connector. A collar on the female coupling prevents
misalignment of the connectors. Verify that the HUD plug is properly aligned and fitted into the mating socket.
– Push plug D into the socket until the locking sleeve E pops forward.
– Test for proper engagement by tugging on the coupling.
6 If the regulator is not attached to the facepiece, proceed as follows:
a Align the regulator outlet port with the facepiece port. (The red purge valve on the regulator will be in the 12
o’clock position). Insert the regulator into the facepiece port.
b Rotate the regulator counterclockwise (as viewed from inside of facepiece) until the red purge valve knob is
on the left side of the facepiece. The lock tab of the E-Z Flo+ regulator or the latch on the E-Z Flo C5
regulator will lock into the facepiece retainer with a click. When the lock tab or latch is properly engaged, the
regulator will not rotate.
WARNING
If the coating is worn through and bare metal is showing on the male quick-disconnect locking ridge, remove
the regulator assembly from service and tag it for replacement. Use of a worn quick-disconnect locking ridge
may result in a malfunction, leading to a loss of breathing air, exposure to harmful substances, serious injury,
or death.
WARNING
Failure to properly check engagement of the coupling as described may lead to hose separation and loss of
breathing air, which may result in serious injury or death.
WARNING
Failure to properly check engagement of the regulator lock tab or latch to the facepiece as described may
result in rotation of the regulator. Any rotation of the regulator may cause the regulator to move out of its
proper position, which may cause loss of breathing air to the user and can lead to serious injury or death.
