The suggested shortest pipe length is 1.5m, in order to avoid
noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how
the unit is installed and the environment in which it is used.)
In sites with poor drainage, use
block bases for outdoor unit.
Adjust foot height until the unit
is leveled. Otherwise, water
leakage or pooling of water may
occur.
