locations:
Near any source of heat, steam, or
combustible gas
Near ammable 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 xed 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
2.3m (90.55in) or more
12cm (4.75in)
or more
12cm (4.75in)
or more
Step 2: Attach mounting plate to wall
The mounting plate is the device on which
you will mount the indoor unit.
● Take out the mounting plate at the back of
the indoor unit.
● Secure the mounting plate to the wall
with the screws provided. Make sure that
mounting plate is at against the wall.
NOTE FOR CONCRETE OR BRICK

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 nish 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 difcult to remove by hand.
Knock-out Panel
3. 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.
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.
● Tighten the nuts to the specied torques.
If overtightened, the nuts could be broken
so refrigerant may leak.
CAUTION
● Keep the piping length at a minimum
to minimize the additional refrigerant
charge due to piping extension.
(Maximum allowable piping length: 15
m (for **09/12*******) and 30 m (for
**18/24*******))
● When connecting the pipes, make sure
that surrounding objects do not interfere
with or contact them to prevent refrigerant
leakage due to physical damage.
● Make sure that the spaces where the
refrigerant pipes are installed comply with
national gas regulations.
● Be sure to perform works such as
additional refrigerant charging and pipe
welding under the conditions of good
ventilation.
● Be sure to perform welding and piping
works for mechanical connections under
the conditions that the refrigerant does not
circulate.
● When reconnecting the pipes, make sure
to perform ared-jointing newly to prevent
refrigerant leakage.
● When working on the refrigerant pipes
and the exible refrigerant connectors,
be careful that they are not damaged
physically by surrounding objects.
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 rmly with
Teon 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.
25
User manual/
Installation manual
● Remove the air lter and pour a small
amount of water into the drain pan to make
sure that water ows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to the following gures.
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
Kinks in the drain hose
will create water traps.
NOT CORRECT

Refrigerant Piping Connection
When connecting refrigerant piping, do not let substances or gases other than the specied
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 efciency of the
unit. Nominal efciency is tested on units with a pipe length of 5 meters (16.5ft) to minimise
vibration & excessive noise.
Refer to the table below for specications on the maximum length and drop height of piping.

Maintenance Procedures
Performing the gas leak tests for repair
In case of repair of the refrigerant circuit,
the following procedure must be kept to
consider ammability.
1 Remove the refrigerant.
2 Purge the refrigerant circuit with inert gas.
3 Perform evacuation.
4 Purge the circuit again with inert gas.
5 Open the circuit.
6 Perform repair work.
7 Charge the system with refrigerant.
8 Flush the system with nitrogen blowing for
safety.
9 Repeat the previous steps several times
until no refrigerant is within the system.
CAUTION
● Compressed air or oxygen shall not be used.
● Flush the system with nitrogen blowing, ll the
refrigerant until the working pressure is reached,
ventilate to atmosphere, and then pull down to a
vacuum state.
● For the nal nitrogen blowing charge, the
system shall be ventilated down to atmospheric
pressure.
● The procedure is absolutely vital in case of
brazing on the pipings.
● Make sure that the outlet of the vacuum pump
is not closed to any ignition sources and there is
ventilation available.
● Do not apply any permanent inductive or
capacitance loads to the circuit without ensuring
that this will not exceed the permissible voltage
and current permitted for the air condiitoner.
Decommissioning
The following requirements must be
fullled before and while taking the
decommissioning procedure:
● Before decommissioning, the worker shall
be familiar with the product details.
● The entire refrigerant shall be recovered
safely.
● Before starting the process, oil and
refrigerant samples shall be taken just in
case analysis is required for reuse.
● Before starting the process, power supply
must be available.
1 Be familiar with the equipment details.
2 Isolate the system electrically.
3 Before starting the process, make sure
that:
● Any mechanical equipment is available for
handling refrigerant cylinders.
● All PPE (personal protective equipment) is
available for servicing.
● The recovery process shall be supervised
by a competent person.
● The recovery equipment and cylinders
comply with the standards.
4 Lower the refrigeration system, if possible.
5 If vacuuming is not possible, make a
manifold so that refrigerant can be easily
removed from the parts of the system.
6 Make sure that the cylinders are placed
on the scales before recovery.
7 Run the recovery system in accordance
with the manufacturer’s instructions.
8 Do not overcharge the cylinders. (No more
than 80 %)
9 Be sure to keep the cylinder within
the maximum working pressure, even
temporarily.
10 After charging, make sure that the
cylinders and the equipment are promptly
removed from the site and all isolation
valves are closed.
