8. Locate the breathing tube over the left shoulder while placing the head
into the head band of the PROFLOW FH22 Hood. Fit the padded portion
of the head band around the fore-
head with the visor window
centered in front of the face. See
FIGURE 8. When properly
donned, the user shall have a
clear unobstructed view through
the visor.
TO ASSURE PROPER OPERATION OF THE HOOD, THERE MUST BE
NO OBSTRUCTIONS TO THE NECK SEAM SUCH AS LONG HAIR OR
ARTICLES OF CLOTHING OR JEWELRY.
9. Pull the cord at the back of the head to draw the head band adjustment
snug and comfortable around the head. Do not over tighten. Check the
tightness of the head band as follows:
a) Hold the inner and outer aprons with your hands and turn your head
from side to side. If the head band slips around your head, tighten it
some more until it does not slip.
b) If the head band will not stay on your head during use, place the
head band back on your head and tighten the head band some more.
10. Smooth the inner apron against the upper body. Draw the neck cord
snug around the neck by holding
the ends of the cord, pressing the
black button inward as you slide
the cord lock toward your throat.
After tightening the cord, loosen it
about one-half inch to permit ease
of movement. A small gap, no
more than two fingers comfortably
between the neck cord and your
throat, must be maintained for op-
timum performance of the hood.
Do not over tighten the neck cord.
See FIGURE 9.
11. When worn with additional protective clothing, the inner apron may be
fitted inside the collar of the protective clothing while the outer apron
drapes over the outside of the protective clothing. The additional protec-
tive clothing must not interfere with the integral exhalation opening on the
front of the hood. Also, the additional protective clothing must not restrict
the air flow to the air filtration elements on the PROFLOW 3. Verify that
the outer apron is laying flat with no folds or wrinkles that would reduce
protection.
12. The blower assembly and breathing tube must be arranged so that:
a) There is enough slack in the breathing tube so the respirator user
can turn his/her head through a full range of motion without the
breathing tube pulling on the PROFLOW FH22 Hood, the breathing
tube being pinched closed or the breathing tube interfering with
other protective clothing or equipment.
b) The blower assembly and breathing tube must not be positioned so
that excessive slack of the breathing tube is likely to catch on objects.
13. Proceed with use of the PROFLOW 3 in accordance with the OPERAT-
ING AND MAINTENANCE Instructions provided with the respirator.
