Install inlet and outlet connections to the switchover. Use an open-end wrench, not a pipe wrench, to install
accessories to the autoswitch system. ¼" NPT connections require the use of PTFE thread tape on the
threads to make a gas tight seal. CONCOA uses PTFE thread tape on all of its regulator NPT connections.
Follow these rules when using PTFE thread tape.
Inspect the NPT threads and if necessary, clean the fitting to remove any dirt or thread sealant that remains
on the threads. Start the PTFE thread tape on the second thread as shown in Figure 3; make sure the tape
does not overlap the end of the fitting. As the tape is wrapped in the direction of the thread spiral, pull tightly
on the end of tape so that the tape conforms to the threads. Wrap the tape around the threads twice. Cut off
the excess tape and press the end firmly into the threads. (See Figure 3 below.)
Installing the inlet connection:
If purchased with pigtails, the male ¼" NPT end of the pigtail is installed into the "INLET" port or in the open,
female port of the valve.
