Refrigerant Line Set Piping
Interconnecting line set between the outdoor
unit and the indoor unit, must have both re-
frigerant lines insulated as the expansion
device is located in the outdoor unit.
Gently bend the line set stubs from the in-
door unit to the desired location. Using 2
x 10”/12” Crescent wrenches remove the
fl are nuts from the indoor unit line stubs.
The indoor unit is fi lled with a dry gas,
check for release of this to ensure that no
leaks are present. Use a small amount of
vacuum pump oil on the male fl are threads
to ease installation.
Connect the line set to the stubs. Using
the 2 wrenches, 1 on the male and 1 on
the female tighten the fl are nuts. Run the
line set to the outdoor unit, avoid tight
bends and kinking the lines.
If line set length is in excess of that re-
quired, cut line set and re-fl are or coil ex-
cess vertically to facilitate oil return to the
compressor
