Donning the Respirator 

Initial Donning 

Prepare to don the blower, battery and hood in a safe, hazard-free area and do the 
following: 
  •  Ensure that the filter/cartridges used are suitable for the contaminant in 

question and are compatible with the EVAHL1 Blower Unit. 

  •  Check that the filter/cartridge is properly mounted on the blower unit. 
  •  Place the battery in the battery compartment on the back of the blower. 
  •  Fit the blower and belt around the user’s waist and adjust the belt for a 

comfortable fit. 

  •  Remove the belt and blower to install the hood or loose fitting facepiece and 

corresponding breathing tube. 

Donning the CC20 Series Hood

Adjusting and Installing Headband Suspension 

in Hood 

  

NOTE

 

20LF and 20LF2 series loose-fitting facepiece hoods have a sewn-in 
headband.

 NOTE

 

  

The 20SICH, 20TICH and GRH Hoods may use a hard hat or suspension.

  

NOTE

 

RT Series hoods do not use a suspension.

1. Adjust headband before installing into 
hood.

2. Turn ratchet until it is at its largest size.

3. Place suspension on head.

4. Adjust ratchet knob until snug and  
    comfortable fit achieved. (Figure 16)

5. Remove from head.

6. Place suspension into hood.

7.  Snap 4 white buttons of suspension into 4 white buttons 

on hood. (Figure 17)

 

  

Adjust Crown Straps for Vertical Fit

To improve suspension comfort, adjust crown 
straps vertically by repositioning the crown 
strap posts in the crown straps.  Vertical 
adjustment makes the headband ride higher or 
lower on the wearer’s head.  To adjust, push 
crown strap post from slot, move to new slot, 
and snap in to secure.  Move key to desired 
vertical position.  Repeat for other crown strap 
post (Figure 18).

  

NOTE

 

If the hood rises off your head during 
use, first verify proper air pressure, then select a different hood for your 
application, or use the optional chin strap.

Adjusting and Installing Hard Hat in Respirator 

Hood 

(20SICH & 20TICH)

1.  Assemble and adjust the standard Bullard hard hat suspensions RS4PC or 

RS6PC or the optional ratchet suspensions RS4RC or RS6RC by following the 
directions on instruction sheet attached to headband 
on hard hat. Read all hard hat warning labels and 
instructions. The following Bullard hard hat models 
are approved for use with  CC20 Series hoods as part 
of a NIOSH approved respirator assembly: C30, C30R, 
S51 and S51R.

2.  If desired, install and adjust optional ES42 hard hat 

chinstrap.

3.  Before inserting hard hat into hood, remove the two 

adhesive-backed Velcro

®

 strips attached to the Velcro 

piece that is sewn into the hood (see Figures 20 & 21).

4.  Peel the backing off the longer Velcro tab and apply it 

to the inside center rear of the hard hat, about 1/4” 
up from the edge. Apply shorter Velcro tab to the underside of the brim of the 
hard hat (see Figure 20).

5.  Insert hard hat into respirator hood with cap visor facing front of hood (see 

Figure 19).

6.  Tuck cap brim on top of front elastic Velcro band sewn into hood (see Figure 

20).

7.  Loop the Velcro strip sewn inside the hood around the back of the cap and affix 

it to the corresponding Velcro tab previously installed inside the hard hat in 
step 4 (see Figure 21).

8.  Remove protective plastic from plastic lens of respirator hood. If desired, 

apply optional 20LCL adhesive-backed lens covers designed to protect the 
respirator’s plastic lens. Apply 2-3 lenses at a time. When lens becomes soiled, 
remove by pulling tab at edge of lens cover to clear your vision.
