The Snap-Tite quick-disconnect for

” id hose does not have a check
valve. If disconnected under pres-
sure, air will discharge through the
connector.
To Reconnect the Quick-
Disconnect Socket
1. Adjustable- or non-adjustable
valve-connector:
a. Temporarily don the support
belt. Push the socket on to the
valve-connector plug end until
it snaps in place.
b. Pull slightly on the air-supply
hose to be sure the connection
is secure.
2. Direct-connect (both

models):
a. Insert the support belt through
the loops in the appropriate
belt holder.
b. Temporarily don the support
belt. Insert the direct-connec-
tor into the socket on the
direct-connector plug end until
it snaps in place.
c. Pull slightly on the air-supply
hose to be sure the connection
is secure.
3. Turn the air source on. Check for
leaks with a commercial leak-test
solution or soapy water. Tighten
connections as required, using
wrenches or slip-joint pliers. Turn
the air source off.
DONNING THE RESPIRATOR
1. If the respirator lens has a paper
cover it must be removed before
the respirator is donned.
Do not remove the special clear
cover lens until it becomes contam-
inated. The cover lens extends the
life of the hood.
2. Turn the air source on. Be sure the
air source pressure and flow match
the requirements of the flow control
device used. The hose length and
pressure required are on the flow
control device or its holder.
Do not don or use the respirator
unless the inlet pressure matches
the specifications listed on page 6.
Reduced pressure may result in
inadequate air volume in the hood.
Failure to follow this precaution
may result in serious personal
injury or death.
3. Don the support belt. On respira-
tors with an adjustable or non-
adjustable valve-connector:
a. Check for a gasket in the cou-
pling nut.
b. Thread the hood tube coupling
nut on the valve-connector and
hand tighten.
Note
If you are using the direct-connector,
its support belt is already attached.
Go to step 5.
4. Slip the belt clip of the adjustable
or non-adjustable valve-connector
over the support belt.
5. Grip the hood and knit collar
between your fingers with both
hands. Stretch the collar and pull
the hood over your head.
