Instructions (PDF):

1. Turn off the main supply of air and water.
2. Unscrew the compression nut from the manual shut-off, making sure to keep the copper or plastic compression fitting within the nut.
3. Slide the 3/8" nipple fitting into the nut through the sleeve and position into the manual shut-off.
4. Finally slide the nut & sleeve onto the threads of the manual shut-off & tighten. The compression fitting should clamp down on the nipple fitting, holding it in place.
5. If the master on/off valve is loose in the manual shut-off or leaks from around the nut, then remove and wrap a few layers of teflon plumbers tape around the nipple and reinstall. Continue until valve has a snug, leak-free fit.
