General:
Use an open-end wrench, not a pipe wrench, to install accessories to the autoswitch system. ALWAYS
hold the bulkhead fitting with a wrench when installing the accessories to the autoswitch
system. Do not allow the bulkhead fitting to turn; otherwise, connections inside the box may
be loosened. NPT connections require the use of Teflon tape on the threads to make a gas tight seal.
(See Figure 6.) On stainless steel connections, the thread sealant helps prevent the connections from
galling together when tightening or loosening. CONCOA uses Teflon tape on all of its NPT connections.
Follow these rules when using Teflon 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 Teflon tape on the second thread as shown in Figure 6; 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.

When Using a Manifold System:
The 1/2" male NPT end of the manifold connector will need to be installed in the inlet port of the
autoswitch. The other end of the manifold connector will be connected to the starter block of the 52B
(brass) or 52S (stainless steel) Series Manifold system. Please follow the instructions provided with
the manifold system when connecting and operating the manifold system.
