HARBOR POINT WALL SPLIT DUCTLESS SYSTEMS
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.
