Honeywell North 5400,7600, RU6500 Series Instruction Manual

g. Insert the outer nut (P/N 80862-H5) onto the housing threads and hand-tighten by turning clockwise. h. Put the remaining inhalation valves (P/N 770017) on the valve seats (P/N 80814A) for the oral/nasal cup (P/N 80815-H5 for medium/large or 80800-H5 for small) making sure they lie flat against the seats. Insert the seat and inhalation valve assembly into the oral/nasal cup. i. Position the oral/nasal cup by first pulling the lower flange on the cup through the small port on the lens so it lies flush with the lens. Straighten the cup by turning it so the peak of the nasal area is on top. Work larger opening of the cup into groove of the speech diaphragm housing that is furthest from the lens. j. Insert the exhalation valve (P/N 770018) into the exhalation valve seat (P/N 80862-H5) and pull in the tab until you hear a “click”. When inserted correctly the flat end of the exhalation valve will be on the thread side of the seat and sit flush with the seat. k. Push the exhalation valve assembly through the lower opening of the oral/nasal cup that is now assembled onto the facepiece. You may need to use a slight pressure to push the assembly completely through. Insert the exhalation housing guard (P/N 80867-H5) onto the housing threads and hand-tighten by turning clockwise. REPLACING THE LENS AND LENS CLAMP ONLY APPLICABLE FOR THE 5400 AND 7600 RESPIRATOR SERIES. For routine cleaning the lens and lens clamps should not need to be removed. For a complete cleaning or repair they may need to be removed and/or replaced. Required: Phillips screwdriver and needle-nose pliers. To remove: 1. Follow instructions above to remove all components. 2. Use the needle-nose pliers to hold the nut on the lens clamp and loosen the screws located on either side of the lens clamp. 3. Pull the lens clamps off the face seal. 4. Pull the face seal away from the lens. To assemble: 1. Work the lens seal onto the facepiece, making sure that it is centered and there are no gaps. 2. Work the upper and lower lens clamps onto the lens and face seal. 3. Use the needle-nose pliers to bring the two lens clamps together. Insert the screws so the thread side faces up. 4. Seat the nut into the cavity of the lens clamp and thread the nut onto the screw and tighten. CAUTION Do not use abrasive cleaners on the lens. Abrasives can remove the protective coating from the lens, making it susceptible to scratch and chemical degradation. STORAGE Store in a clean, dry area away from the chance of any contamination. Use the respirator storage bag provided with the facepiece or any other sealable container that will protect the facepiece. Optimum storage conditions are room temperature, between 50°F (10°C) and 100°F (38°C). WARNING Never store the facepiece with cartridges or filters that have been exposed to contaminants. If cartridges and/ or filters are be reused, seal them in a separate bag or container. Do not expose to direct sunlight, chemical pollutants, or dust. Cartridges that have been exposed to contaminants with a low boiling point, and all NIOSH rated R filters that have been exposed to oil-based aerosols must be discarded at the end of a shift. When discarding contaminated cartridges, facepieces or components, follow local, state and/or national regulations pertaining to disposal of HazMat and/or other contaminated articles. Consult your supervisor and/or proper authorities. Failure to comply with these warning will result in the risk of serious injury, illness or death. CAUTION Do not expose the respirator to excessive heat (above 140°F [60°C]), moisture or contaminative substances, or stack undue weight on top of the facepiece or components during storage because such conditions may distort the facepiece, resulting in the inability to achieve a proper fit the next time the facepiece is worn, or they may compromise the functionality of the component.
