Failure to follow these precautions
can result in serious personal injury
or death.
A. Supplied-Air Type Respirators
1. Be sure that inlet air pressure is
set to agree with the valve-con-
nector you are using. Use the
information in the chart as a guide.
The air source must provide at least
4 cubic feet per minute (cfm) to
each respirator, and maintain the
required inlet pressure range speci-
fied in this manual for the specific
flow control device selected.
If the air supply pressure is greater
than 15 psig (BLACK body), 40 psig
(GOLD body), or 80 psig (Vortex
tube), be sure to use a pressure
regulator between the air supply
and air-supply hose. Adjust the reg-
ulator to deliver air at the pressures
specified by the valve-connector or
vortex tube you are using. Failure to
follow precautions can result in
serious personal injury or death.
Inlet air must have a dew point of
less than 0 degrees F and a tem-
perature between 60 degrees F and
140 degrees F. Higher dew points,
or air temperatures below 60
degrees F, may cause moisture to
freeze in the vortex and reduce air
flow. Air temperatures above 140
degrees F may damage the vortex.
2. Reconnect the socket assembly to
the flow control valve (valve-con-
nector, regulator, or vortex tube).
3. Slide the belt clip of the flow con-
trol over the support belt. Don the
support belt and position the flow
control so that it will be on your
left side. The vortex tube should
be worn on your right side so that
the air-supply hose will be behind
you.
4. Turn the air supply on. Check for
leaks with a commercial leak
detection solution or soapy water.
Tighten connections as required.
Turn off the air source.
5. Turn the back of the hood and
collar “wrong-side-out,” exposing
the facepiece headstraps. The
Velcro strip on the collar does not
have to be unfastened unless a
protective cap is worn.
6. Adjust the facepiece headstraps
so the end tabs are at the buckles.
7. Grip the facepiece between your
thumb and fingers with both
hands. Insert your chin into the
lower part of the facepiece. Pull
the facepiece headstraps over
your head. Smooth the straps flat
against your head.
a. Support the facepiece by hold-
ing the breathing tube at the
coupling nut assembly with
one hand.
b. Tighten the lower (neck) straps.
Pull the straps straight back,
not out.
c. Tighten the side (temple) straps.
d. Tighten the front (forehead)
strap to position the lens for
best vision and to support the
weight of the facepiece.
8. Skip section B, below. Refer to C.
Air-Tightness Test (Face-to-
Facepiece Seal).
