I'm here to answer your questions about these couplers and their usage.

Use a wrench to assemble the coupler with both F1 and F2 on the
corresponding lineset. Make sure the thread is screwed to the bottom
until it stops (as shown below).

After the connection is complete, cover the F1, F2, and coupler connections with
the grey insulating sleeve to help prevent condensation (as shown below).

Slide the insulation sleeves together ensuring no copper wiring is
exposed and secure in place using tape.
