4. Ensure that the screw connectors do not
cross-thread as you tighten them and work
quickly.
IMPORTANT: Since the coupling works
with tapping rings, it may leak if you undo
and reconnect the pipes. This will also void
the warranty.
5. After finishing the connection, use the tape
to wrap the refrigerant pipe and connecting
cable together. NOTE: In North America,
the cable should be protected by an
applicable conduit.
