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).
