to unnecessary turns and bends in the
refrigerant piping lines connecting
outdoor unit with indoor unit.
Avoid installation location where there are
obstacles near the air outlet or air inlet
that may affect air flow and performance
of the unit
Avoid multiple unit installation with units
facing each other and blowing discharged
air into each other.
