PUR Water Purification Products Air Filter - Manual (Page 5)

You should not enter any potentially contaminated atmosphere unless you have confirmed all of these factors.
1.1.4 TRAINING PROGRAM
These brief written instructions cannot substitute for a formal Respirator Training Program. Such training should include an opportunity
for you to handle the respirator, learn how to inspect it, have it properly fitted, wear it in normal air for a long familiarity period, and
finally, to wear it in a test atmosphere. The Training Program should be based on ANSI Z88.2-1992, and should familiarize you with
OSHA Regulation 29CFR Section 1910.134 and other regulations promulgated by various Regulatory Authorities.
2 PRE-USE INSTRUCTIONS
Visually check the headgear and head cover to identify signs of damage or wear that may affect performance. Discard and replace the
headgear or head cover if there are any damaged or worn parts.
Refer to the Compact Air Operating and Maintenance Instruction Manual for information on the pre-use instructions and operation of
the Compact Air PAPR battery and blower assembly.
2.1 ADJUSTING THE HEADGEAR
The Primair headgear has three adjustments to maximize comfort and fit. Adjust the headgear to the proper size by following the steps
noted below. Adjustment A is the primary adjustment and need not be readjusted after a comfortable and secure fit is achieved.
Adjustment B sets the height of the headgear on your head, and may be adjusted more frequently if desired. Adjustment C is the ratchet
that sets the circumference of the headgear to your head, and will be adjusted each time you put the Primair headgear on.
1.
Adjustment A: The primary adjustment is preset to a medium. To readjust to a smaller or larger size, slip your finger under the top
lateral strap located towards the back of the headgear, unsnapping it from the yellow locking pin (figure 1). Repeat this procedure
with the lower lateral strap. Move the lower strap so the desired hole (small, medium or large) is aligned with the yellow locking
pin and snap the strap back onto the pin. Move the top strap so the desired hole is over the yellow pin and snap into place
(figure 2).Be sure that the ends of the lateral straps are under the yellow air duct attachment.
2. Adjustment B: To set the height of the headgear on your head, squeeze the two tabs on the center lateral strap with your thumb
and forefinger, releasing the locking mechanism, and pull each side of the center strap to widen the strap (figure 3). Place the
headgear on your head. Squeeze the center tabs again to release the locking mechanism, and push or pull each side of the center
strap to shorten or lengthen the strap. Adjust until the headgear is comfortable and at the desired height on your head.
3. Adjustment C: Turn the ratchet clockwise to tighten the headgear so that you have a snug and comfortable fit (figure 4).
Readjustments of the center lateral strap (Adjustment B) and the ratchet (Adjustment C) can be made at this time for the most
comfortable and secure fit. If you are unable to achieve a snug and comfortable fit, readjust the back lateral straps to a smaller or
larger size, then repeat steps 2 and 3.
2.2 ASSEMBLING THE HEAD COVER ON THE HEADGEAR
1. Slip the head cover over the headgear, so the two openings of the head cover line up with the ratchet and manifold orifice.
2. Pull the yellow end of the manifold orifice through the upper hole of the head cover, making sure the yellow connector is
completely through the hole (figure 5).
3. Pull the ratchet through the lower hole, so that the ratchet is easily accessible, and the elastic strap is under the ratchet wheel.
4. Snap the head cover onto the male snaps on the headgear. The Primair has four (4) female snaps, and the Primair Plus has two (2)
female snaps. For the Primair Plus snap the female snaps to the male snaps that are closest to the front of the headgear. (Furthest
away from the ratchet adjustment at back)
