Refrigerant Line Set Piping
Interconnecting line set between the
outdoor unit and the indoor unit, must have
both refrigerant 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 flare nuts from the indoor
unit line stubs.
The indoor unit is filled 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
flare 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 flare
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-flare or
coil ex- cess vertically to facilitate oil
return to the compressor.
