mounting
plate
to
the back of the indoor
unit.
2. Place
the mounting plate againstthe
wall
in alocation that meets the standards
in
the
Select Installation Location step. (See
Mounting Plate Dimensions for
detailed
information on mounting plate sizes.)
3. Drill holes for mounting

that:
• have studs and can support the weight
of
the
unit
• correspond
to
screwholes in the
mounting
plate
4. Secure
the mounting plate
to
the wall
with
the screws
provided.
5. Make surethat mounting plate
is
flat against
the
wall.
NOTE FOR CONCRETE OR BRICK
WALLS:
Ifthe
wall ismade
of
brick, concrete,
orsimilar
material,
drill
5mm-diameter
(0.2in-diameter)
holes
inthe
wall and insert
the
sleeve
anchors
provided. Then secure
the
mounting plate
to
the
wall
bytighteningthe
screwsdirectly
into
the
clip
anchors.
Step 3:Drill wall hole
for
connective
piping
Youmust
drill
ahole
inthe
wall
forrefrigerant
piping,
the
drainage pipe, and
the
signal
cable
thatwill
connect
the
indoor and
outdoorunits.
1.
Determine
the
location
ofthe
wall hole
based
onthe
position
ofthemounting
plate.
Refer
to
Mounting PlateDimensions
onthe
next page
to
help you determine
theoptimal
position. Thewall hole should have a

Step 4:Prepare
refrigerant
piping
The
refrigerantpiping
isinside an
insulating
sleeve attached
to the
back
of the unit.
You
must
prepare
the piping
before passing
it through the
holein the
wall. Refer
to the
Refrigerant
Piping
Connection section
of this
manual
for detailed
instructions
on pipe flaring
and flare
to
r
que
requirements, technique,
etc.
1.
Based
on the position of the wall hole relative
to the mounting
plate, choose
the
side
f
rom
which the piping will exit the unit.
2. Ifthe wall hole
is
behind the unit,
keep
the
knock-out
panel
in
place.
Ifthe wall hole
is
to
the
side
of the indoor unit,
remove
the plastic
knock-out
panel
from that
side
of the unit.
(SeeFig. 3.3 ).This
will
create a
slot
th
rough
which yourpiping
can
exit the unit. Use
needle nose pliers
if the
plastic panel is
too
difficult to
remove
byhand.
3. Use scissors
to
cut down the length
ofthe
insulating sleeve
to
revealabout 15cm
(6in)
of
the refrigerant piping.
This serves
two
purposes:
• Tofacilitate the Refrigerant
Piping
Connection
process
• To facilitate
Gas Leak Checks
and enable
you
to
check for
dents
4. If existing connective piping is
already
embedded
in
the wall, proceed directly
to
the Connect Drain Hose step. If there is
no
embedded piping, connect the indoor
unit
’
s
refrigerant piping
to
the connective
piping
that
will
join the indoor andoutdoor
units.
Refer
to
the Refrigerant Piping
Connection

.
5.
Based
on theposition
of
the wall hole
relative
to
the mounting plate, determine
the
necessary angle
of
your
piping.
6. Grip the refrigerant piping at the base
ofthe
bend.
7.
Slowly
,
with
even pressure, bend the
piping
towardsthe
hole.
Do
not

back
of the unit).
Howeve
r
,
it
can also be attached
to
the right-hand side.
1. To ensure proper drainage, attach the
drain
hose on the same side that your
r
efrigerant
piping exits the
unit.
2. Attach drain hose extension
(pu
r
chased
separately)
to
the end of drain hose.
3. Wrapthe connection point firmly with
T
eflon
tape
to
ensure a good seal and
toprevent
leaks.
4. For the portion of the drain hose that
will
remain indoors, wrap
it
with foam
pipe
insulation
to
prevent
condensation.
5. Remove the air filter and pour a small
amount
of water into the drain pan
to
make sure
that
water flows from the unit
smoothl
y
.

with
a
capacity
of
1.5 times the maximum current
of
the
unit.
6.
If connecting power
to
fixed wiring, aswitch or circuit breaker that disconnects all poles
and
has a contact separation
of
at least1/8in (3mm) must be incorporated
in
the fixed wiring.
The
qualified technician must use an approved circuit breaker or
switch.
7.
Onlyconnect the

.
Double-check that all items
a
r
e
bundled in accordance with Fig.3.10.
DO NOT WRAP ENDS OF PIPING
Whenwrapping the bundle, keep the
ends
of the piping unwrapped. You need
to
access
them
to
test for leaks at the end of
the
installation process(refer
to
Electrical Checks
and Leak Checks section of this
manual).
Step 8:Mount indoor

If you installed new connective piping
tothe
outdoor
unit,
do the
following:
1.
If you have already passed the
refrigerant
piping through the hole in the wall,
p
r
oceed
to
Step 4.
2.
Otherwise, double-check that the ends of
the
refrigerant pipes are sealed
to
prevent
dirt or
foreign materials from entering the
pipes.
3.
Slowly pass
the wrapped bundle of refrigerant
pipes, drain hose, and signal wire through
the
holein the
wall.
4.
Hookthe top of the indoor unit on the
upper
hookof the mounting
plate.
5.
Check that unit ishooked firmly on
mounting
by applying slight pressure
to
theleft
and
right-hand
sides of the unit. The unit
should
not jiggle or
shift.
6.
Using even pressure, push down on
the
bottom halfof the unit.
Keep pushing
down
until the unit snaps onto the hooks along
the

mounted
DRAIN HOSE MUST BE ON
BOTTOM
Make sure
that the
drain hose is
atthe
bottom
ofthe
bundle.Putting
the
drain hose
at
the
top
of the
bundle can cause
the
