When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process.
The indoor unit makes noises
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor unit and outdoor unit make noises
Low hissing sound during operation: This is normal and is caused by
refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping
or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.

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
unit A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
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:
15cm (5.9in) or more
12cm (4.75in) or more
12cm (4.75in) or more
2.3m (90.55in) or more
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.
Screw
Secure the mounting plate to the wall with the screws provided. Make sure that
mounting plate is flat against the wall.
NOTE FOR CONCRETE OR BRICK WALLS: If the wall is made of brick, concrete, or
similar material, drill 5mm-diameter (0.2in-diameter) holes in the wall and
insert the sleeve anchors provided. Then secure the mounting plate to the wall
by tightening the screws directly into the clip anchors.

Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based on the position of the
mounting plate. Refer to Mounting Plate Dimensions.
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.

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. 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. 3. 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.
Knock-out Panel
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 and outdoor units. Refer to the Refrigerant Piping
Connection section of this manual for detailed instructions.
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.
Step 5:Connect drain hose
By default, the drain hose is attached to the lefthand 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.
For the portion of the drain hose that will remain indoors, wrap it with foam
pipe insulation to prevent condensation. 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 follo.wing figures.
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.
Indoor Unit Installation
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.
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.

Refrigerant Piping Connection
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.
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).
Refer to the table below for specifications on the maximum length and drop
height of piping.

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.
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.

Step 2: Remove burrs Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent burrs from falling into the
pipe.
2. Using a reamer or deburring tool, remove all burrs from the cut section of
the pipe.

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:
