** 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.)
When connecting the FVXS indoor unit, the shortest piping
length should be no less than around 2.5m.
In sites with poor drainage, use

is leveled. Otherwise, water
leakage or pooling of water may
occur.
