Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. Sheath the pipe with insulating material as necessary
2. Remove the cut-off valve of the outdoor unit and take out
the flare nut from the bag of indoor unit accessories. Fit
the flare nut on the pipe. See Fig 2.11.
3. Make sure it is facing in the right direction, because you
cannot remove the nut or change its direction once the
pipe has been flared. See Fig. 2.12.
4. Remove PVC tape from the end of the pipe when ready to
perform flaring work.
5. Clamp flare form on the end of the pipe. The end of the
pipe should extend ~ 1/16 in (1.6 mm) beyond the edge of
the flare form, as shown in Fig. 2.14.
6.
Place flaring tool onto the form, as shown in Fig. 2.13.
7
. Turn the handle of the flaring tool clockwise until the pipe
is fully flared, as shown in Fig. 2.13.
8.
Remove the flaring tool and flare form, then inspect the
end of the pipe for cracks and even flaring.
