PIPE JOINTS:
There are pipe threads on a variety of components in the vending machine. The threads on them are
sealed with teflon tape to prevent water leakage. If any of these components have been taken out for
servicing or if the joint leaks, new teflon pipe thread seal tape needs to be put on.
ATTENTION: USE A STRAP WRENCH TO TIGHTEN OR LOOSEN PLASTIC FITTINGS.
DO NOT USE A PIPE WRENCH AS ITS TEETH MAY DAMAGE THE PART.
1. Remove old teflon tape from component or fitting. Be careful not to allow any tape
fragments to fall into tubings or fittings as they may get caught in solenoids and pumps,
which causes damage to them.
2. Teflon tape should be wrapped around male threads only. Starting at the second thread
from the edge, wrap new teflon tape at a clockwise direction, with the threaded end
facing you). Overlap half the width of each wrap and circle the threads a minimum of
two times. (see diagram 25)
3. Screw component or fitting back into its place. For anything plastic, hand tight plus one
to 1 1/2 turns is enough. Check for leaks.
