Assembly of 3M 604 Exhalation Valve Filter

• Ensure the valve cover of the 6000 Series facepiece is clean, uncontaminated and undamaged. The valve cover is on the front of the respirator and has a large 3M logo. There are four breathing slots surrounding the logo.
• Align the connector tabs and hooks on the back of the EVF with the breathing slots of the valve cover. Tip: Installing the EVF with either hook at the top position may help with proper alignment of the EVF.
• Press the EVF onto the valve cover. The EVF should sit evenly on the valve cover.
• If the EVF is not seated evenly on the valve cover.
• Slowly rotate the EVF clockwise until rotation stops. Pull outward lightly on the EVF to confirm a complete connection.

Positive Pressure Seal Check

• Place the palm of your hand over the center of the EVF and exhale gently. If facepiece bulges slightly and no air leaks are detected between your face and the facepiece, a proper seal has been obtained.
• If faceseal air leakage is detected, reposition respirator on your face and/or readjust tension of the elastic straps to eliminate leakage.
• Repeat above steps until a proper seal is obtained.
