[. . . ] The on (`I') position of the switch is at 12 o'clock, while the off (`O') position is at 9 o'clock. Once the machine has been turned on you will be able to tell if the vacuum is in the proper rotation by placing your hand over the exhaust tube (Photo 2). If your machine has a downstream HEPA filter, the air will exhaust from the area shown in Photo 3. [. . . ] If you have previously purchased a 3156 vacuum and have not used the Safe-Pak with it before, then you should have received some additional components with the Safe-Pak as part of a kit that will allow the operator to install these components into the 3156 machine. The additional components to retrofit a 3156 for use with a Safe-Pak include two washers and an inlet plug. These components are pictured in Photo 4. The washers are designed to elevate the plate (Photo 5) on which the Safe-Pak will sit. It may be necessary to elevate the Safe-Pak so that it will seat up against the housing of the vacuum. This will prevent any air leakage, allowing the vacuum to perform at it's peak level and draw in the maximum amount of air. Photo 4 Check how well the Safe-Pak seals against the vacuum housing by placing the Safe-Pak on the plate pictured in Photo 5. The plate is raised by turning the black lever (Photo 6) in a counterclockwise direction. Make sure the perimeter of the Safe-Pak lines up with the perimeter of the vacuum housing. While turning the lever in the counterclockwise direction, you should feel some resistance at about the 1 o'clock position. You should be able to continue rotating the lever past the 12 o'clock position until it comes to a stop at about the 11 o'clock position. Check to see if there are any gaps between the perimeter of the SafePak and the vacuum housing. You might also want to check for any air leakage by turning the vacuum on and feeling for leaks around the perimeter of the Safe-Pak. If there are any significant gaps or leaks around the Safe-Pak, you may want to add one or two washers as spacers to raise the level of the plate in order to get a tighter seal with the Safe-Pak. Photo 5 Photo 6 To install the washers simply remove the plate by unscrewing the bolt from the center of the plate. The bolt fastens the plate to the shaft underneath (Photo 7). To add height to the shaft, the washers need to be placed on top of the shaft as pictured in Photo 8. The plate will need to be placed on top of these washers. [. . . ] To remove it you simply depress the button on the orifice to relieve the tension and pull the plug out of the orifice. Photo 8 Photo 9 This completes the installation of the retrofit hardware needed for the Safe-Pak. Your CFM Model 3156 vacuum is now ready to be used with a Safe-Pak. If you intend to use the 3156 for applications other than in conjunction with the Safe-Pak, you must completely remove the washers used to raise the elevation of the plate pictured in Photo 5.
