centers)
CAUTION
**Set the piping length
from 4.92ft (1.5m) to
98.4ft (30m).
Stop valve cover
Where there is a danger of
the unit falling, use foot bolts,
or wires.
In sites with poor drainage,
use block bases for outdoor

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.)
