To prevent wall damage, use a stud finder to
locate studs to mount the units to.
A minimum pipe run of 9.8 ft (3 m) is required
to minimize vibration & excessive noise.
Two of the A, B, and C air circulation pathways of
of the outdoor unit must be free from
obstructions at all times (Refer to illustration).
This illustration is for demonstration

Additional Line Sets & Coupler Kit
If you find the default line set lengths are not
sufficient for your application, additional line sets
are available for purchase. You will also need a
coupler kit (pictured below), which will allow two
standard line sets to be connected together. The
coupler kit is installed and checked for leaks by
following the same steps described in this manual
for connecting the line set to the indoor air handler
(Refer to Section 7: Refrigerant Piping Connections
for these steps).
