BREATHING AIR DISTRIBUTION SYSTEM

DURING OPERATION

1. Check the manifold pressure gauge reading periodically. Keep the reading in the specified range specified by NIOSH
for the respirator.
a. If the reading changes, adjust the pressure regulator until the gauge reads within the specified range.
b. Stop operation and remove the respirators if the manifold pressure cannot be brought within the proper range.
c. Inspect the system for restrictions, such as a partially closed valve or a clogged filter element.
2. The auto drain will periodically drain moisture from the filter.
If moisture is not properly removed from the system properly, the system may be contaminated
and malfunction, and/or contaminated moisture may reach the respirator. Failure to follow this
warning can result in serious personal injury or death.
3. Check the filter change indicator periodically.
Note: Air must be flowing through the filtration unit before the indicator will function. The indicator will change from
green to red when a filter change is required.
When required by government regulations and if noise or other factors may prevent user from
hearing the low pressure alarm during respirator use, have a responsible person monitor the unit
and the air supply. The person must be required to alert the respirator user if an alarm or other
condition occurs requiring the user to exit the contaminated atmosphere. Failure to follow this
warning can result in serious personal injury or death.

SHUTDOWN

1. Ensure all personnel have completely exited the work area.
2. Shut off the air source to the point of attachment box.
3. Remove air pressure from the point of attachment box by pulling the ring on the relief valve located on the manifold.
4. Disconnect the breathing airline hoses.
5. Install the dust caps, if applicable, and close the cover.
MAINTENANCE
Always depressurize the system before performing service.

Filter Change Instructions

1. After 300 of use or when the filter change indicator turns red the filter must be replaced to prevent flow reduction
through the unit.
2. Gently pull the drain tube, if applicable, up and through drain hole in the bottom of the case, so the end of the tube is
inside the case.
3. Remove the filter bowl and cover.
a. Press and slide the latch down.
b. Rotate the bowl left or right while pulling down until the bowl and cover slides out of the filter head assembly.
4. Remove the filter element
a. Grasp the bottom of the element and rotate it counter-clockwise until the element is removed.
5. Clean the bowl and cover with mild soap and water, rinse, and allow to air dry.
6. Examine the bowl and cover for cracks and discoloration. Replace if necessary.
7. Install the new filter element
a. Locate the new o-ring in place, on top of the filter element,
b. Index the threads of the filter element to the filter head and turn the element clockwise until snug. DO NOT OVER-
TIGHTEN FILTER ELEMENT. A CRACKED ELEMENT OR STRIPED THREADS WILL RESULT.
8. Reinstall the filter bowl and cover.
a. Slide the filter bowl and cover over the filter element into the filter head, with the latch facing to the front.
b. Rotate left and right slightly until the latch engages with the head assembly. A "click" sound will occur at time of
engagement, as the latch is spring loaded.
c. Check security of the bowl by pulling down on the bowl assembly.
