required for refrigerant pipe
exceeding 10m in length.
Wrap the insulation pipe with
the finishing tape from bottom
to top.
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.
Where there is a danger of the unit
falling, use foot bolts, or wires.

1.5m
Min. allowable piping length
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 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.
CAUTION
**Set the piping length
from 1.5m to 20m.
Allow 300mm of
work space below
the ceiling surface.
