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.)
Wrap the insulation
pipe with the finishing
tape from bottom to top.
Allow 11-13/16 inch (300mm)
of work space below the

Also insulate the connection on the outdoor unit.
Use tape or insulating material on all connections
to prevent air from getting in between the copper
piping and the insulation tube.
Be sure to do this if the outdoor unit is installed
above.

Level mounting base
(available separately)
If there is the danger of the unit falling
or overturning, fix the unit with
foundation bolts, or with wire or other
means.
If the location does not have good
drainage, place the unit on a level
mounting base (or a plastic pedestal).
Install the outdoor unit in a level
position. Failure to do so may result in
water leakage or accumulation.
CAUTION
** Set the piping length
from 4.92ft (1.5m) to
98.4ft (30m).
