CAUTION
**Set the piping length
from 4.92ft (1.5m) to
65.6ft (20m).
Where there is a danger of
the unit falling, use foot bolts,
or wires.
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.

Be sure to add the proper amount of additional refrigerant.
Failure to do so may result in reduced performance.

The suggested shortest pipe length is 4.92ft (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 FDXS12 indoor unit, the shortest piping length
should be no less than 9.84ft (3m).
