NOTE: Do not apply excessive force to these parts.
1. For right side and lower side piping, cut the indoor unit
base(s) with a hacksaw and deburr the cut end with a
file. (See Fig. 5)
2. Hang the indoor unit(s) on the upper portion of the instal-
lation plate while inserting the vinyl-taped pipes through
the wall hole. Engage the lower projection with the claws
of the installation plate. (See Fig. 7)
NOTE: Make sure that the unit(s) are securely mounted, by
slightly shaking the indoor unit(s).
The length of the cable
which will be passed
through the wall hole
should be longer than 40”.
1. Regarding the left rear sided and left sided piping, the pipes
must be connected indoors and must be adjusted to the
actual installing length. Keep these pipes unrolled (See
Fig. 9 and Fig. 10)
2. For left side piping, cut the indoor unit base(s) with a hack-
saw and deburr with a file.
