These steps must be followed each time the respirator is used.
WARNING!
• This respirator must be used only by trained personnel and according to MSA's instructions.
• Do not use the respirator as an underwater device.
• Wear impermeable protective clothing if exposed to poisons which can be absorbed by the skin.
• Wear appropriate protective clothing to protect your body from rebounding abrasive material.
• This system must be supplied with respirable air. See ANSI Z86.1-1973 [Compressed Gas Association Specification G-
7.1 for Quality Verification Level (Grade D) Gaseous Air].
• The air source must provide at least 4 cubic feet per minute (cfm) to each respirator, and maintain the required inlet
pressure range specified in this manual for the specific flow control device selected.
• If the air supply pressure is greater than maximum inlet pressure specified by the flow control device you are using, be
sure to use a pressure regulator between the air supply and air-supply hose. Adjust the regulator to deliver air at the
pressures specified by the flow control device you are using.
Failure to follow these warnings can result in serious personal injury or death.
4.1
Section A: Constant Flow Supplied-Air Type Respirators
1. Be sure that inlet air pressure is set per the following guidelines:
Gold Body
• High Pressure Systems Constant Flow
• Approved Air-Supply Hose Length: 8-300 ft.
• Approved inlet air pressure to maintain 4 CFM minimum to facepiece: 35-40 psig
2. Reconnect the socket assembly to the flow control valve (Constant Flow pictured).
3. Slide the belt clip of the flow control or the Duo-Flow valve over the support belt. Don the support belt and position the
valve so that it will be on your left side.
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.
NOTE:
Attach the appropriate filter to the coupling nut at the bottom of the Duo-Flo valve.
5. Turn the back of the hood and collar “inside-out,” exposing the facepiece headstraps.
6. Adjust the facepiece headstraps so the end tabs are at the buckles.
