PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the
label on the product box to make sure that the
model number of the indoor unit matches the
model number of the outdoor unit.
Step 1: Select installation location
Before installing the indoor unit, you must
choose an appropriate location. The following
are standards that will help you choose an
appropriate location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
Convenient drainage
Noise from the unit will not disturb other
people
Firm and solid—the location will not vibrate
Strong enough to support the weight of the

DO NOT install unit in the following
locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains or
clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
Drill wall hole for connective piping step)
for the signal cable and refrigerant piping
that connect the indoor and outdoor units.
The default position for all piping is the right
side of the indoor unit (while facing the unit).
However, the unit can accommodate piping to
both the left and right.
Refer to the following diagram to ensure
proper distance from walls and ceiling:
Step 2: Attach mounting plate to wall
The mounting plate is the device on which you
will mount the indoor unit.
Remove the screw that attaches the mounting
plate to the back of the indoor unit.
Secure the mounting plate to the wall with
the screws provided. Make sure that mounting
plate is flat against the wall.

Determine the location of the wall hole based
on the position of the mounting plate. Refer
to Mounting Plate Dimensions.
Wall
Indoor Outdoor
mm7-5
(0.2-0.275in)
MOUNTING PLATE DIMENSIONS
Different models have different mounting plates.
For the different customization requirements, the
shape of the mounting plate may be slightly
different. But the installation dimensions are the
same for the same size of indoor unit.
See Type A and Type B for example:
Correct orientation of Mounting Plate
2.
Using a 65mm (2.5in) or 90mm(3.54in)
(depending on models )core drill, drill a
hole in the wall. Make sure that the hole
is drilled at
a slight downward angle, so
that the outdoor end of the hole is lower
than the indoor end by about 5mm to 7mm
(0.2-0.275in). This will ensure proper water
drainage.
3.
Place the protective wall cuff in the hole. This
protects the edges of the hole and will help
seal it when you finish the installation process.
CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
components.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. You
must prepare the piping before passing it
through the hole in the wall.
1. Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit.
2.
3.
If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.
This will create a slot through which your
piping can exit the unit. Use needle nose pliers
if the plastic panel is too difficult to remove by
hand.
Groove has been made in the knock-out
panel in order to cut it conveniently. The
size of the slot is determined by the diameter
of piping.
4.
If existing connective piping is already
embedded in the wall, proceed directly to
the step. If there is no Connect Drain Hose
embedded piping, connect the indoor unit’s
refrigerant piping to the connective piping
that will join the indoor and outdoor units.
Refer to the Refrigerant Piping Connection
secti on of this man for ual detail insed tructi s.on
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four different angles:Left-hand side,Right-hand
side, Left rear, Right rear.
Knock-out Panel
CAUTION
Be extremely careful not to dent or damage
the piping while bending them away from
the unit. Any dents in the piping will affect
the unit’s performance.
Step 5:
Connect drain hose
By default, the drain hose is attached to the left-
hand side of unit (when you’re facing the back
of the unit). However, it can also be attached to
the right-hand side. To ensure proper drainage,
attach the drain hose on the same side that your
refrigerant piping exits the unit. Attach drain hose
extension (purchased separately) to the end of
drain hose.
Wrap the connection point firmly with Teflon
tape to ensure a good seal and to prevent leaks.
Remove the air filter and pour a small amount
of water into the drain pan to make sure that
water flows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to the following figures.
.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks
you must plug the unused
drain hole with the rubber
plug provided.
CORRECT
Make sure there are no kinks
or dent in drain hose to ensure
proper drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water.
This will prevent proper
drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
For the portion of the drain hose that will remain
indoors, wrap it with foam pipe insulation to
prevent condensation.

Note on Pipe Length
The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal
efficiency is tested on units with a pipe length of 5 meters (16.5ft)(
In North America, the standard pipe
length is 7.5m (25’)
. A minimum pipe run of 3 metres is required to minimise vibration & excessive noise.
In special tropical area, for the R290 refrigerant models, no refrigerant can be added and the maximum
length of refrigerant pipe should not exceed 10 meters(32.8ft).
Connection Instructions – Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
1. Measure the distance between the indoor
and outdoor units.
Refer to the table below for specifications on the maximum length and drop height of piping.
When connecting refrigerant piping, do not let substances or gases other than the specified
refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and
injury.
2. Using a pipe cutter, cut the pipe a little longer
than the measured distance.
3. Make sure that the pipe is cut at a perfect 90°
angle.
Oblique Rough Warped
90°
DO NOT DEFORM PIPE
WHILE CUTTING
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efficiency
of the unit.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. For example, in North America, the standard pipe length is 7.5m (25’).
In other areas, the standard pipe length is 5m (16‘). The refrigerant should be charged from the service
port
on the outdoor unit’s low pressure valve.
The additional refrigerant to be charged can be
calculated using the following formula:
CAUTION DO NOT mix refrigerant types.
For R290 refrigerant unit, the total amount of refrigerant to be charged is no more than:
387g(<=9000Btu/h), 447g(>9000Btu/h and <=12000Btu/h), 547g(>12000Btu/h and <=18000Btu/h),
