• Attach the flare nuts to the indoor coil, using the same
process and precautions as found above for the outdoor
section flares.
• Using a torque wrench and back-up wrench, tighten the
indoor coil flare nuts to match the torque specification
chart.
• With the service valves closed, fill each tube with 500 PSI
of dry nigrogen and check for leaks.
• The indoor coil comes precharged with R410A so there is
no need to purge or evacuate the indoor coil.
• Evacuate the line set to at least 350 microns. From the
final micron level obtained, shut off the vacuum pump. If
the system rises no more than 150 microns within a minute
and stops, the evacuation can be considered sufficient.
• If the system rises more than 150 microns from the
original vacuum, there is either a leak or moisture has
not been removed. Locate and repair leak, or continue
evacuation as needed.
• When the evacuation is complete, replace the service valve
cores through the core removal tool.
• • Add additional refrigerant charge if needed before you
open indoor service valves if indoor coil is so equipped.
• Record the amount of refrigerant added in permanent ink
at the line set length location entered earlier.
Screw on the flare nut of the flaring connecting pipe on the
outdoor unit valve.

NOTE: It shows the gauge connection will need to have the high side gauge hose connected to the high side liquid valve so both
lines can be evacuated and leak checked.
