To minimize the possibility of filter element rup- ture, it is important that ONLY replacement ele- ments identified with the Sullair name, logo and appropriate part numbers be used, and that sub- stitute elements NOT be used, due to the fact that such filters may have inadequate or questionable working pressure ratings.
Section 7 MAINTENANCE 6. Lubricate the new seals with the same type of Figure 7-3 Separator Element Replacement fluid used in the compressor and position each seal in its appropriate place. 7. Carefully push the element into position under the housing/head. 8.
3. Loosen and remove the eighteen (18) hex head capscrews from the cover/lid plate. To assist with the removal of the tank lid, Sullair has provided a 1”-8unc nut to the top lid so it can be removed by a 1”-8unc eyebolt (which is avail- able from Sullair) or a similar type of lifting device.
