conditioner again by pressing the Power button.
I cannot change
the temperature.
Cool air does not
come out of the air
conditioner.
I cannot change
the air flow
direction.
• Check whether the Fan or Fast mode is running. In these modes, the
air conditioner controls the set temperature automatically, and you
cannot change the set temperature.
• Check whether the set temperature is higher in the Cool mode
than the current temperature. Press the Temperature button on the
remote control to change the set temperature.
• Check whether the air filter is blocked with dirt. If the air filter
is blocked, the cooling performance may decrease. Remove dirt
regularly.

obstacles. Remove the coverings and obstacles.
• Check whether doors or windows are open. This may cause poor
cooling performance. Close the doors and windows.
• Check whether the air conditioner is turned on immediately after the
cooling operation stops. In this case, only the fan runs to protect the
outdoor unit compressor.
• Check whether the pipe length is too long. When the pipe length
exceeds the maximum pipe length, the cooling performance may
decrease.
• Check whether the good'sleep function is running. While this
function is running, you cannot control the air flow direction.
Cleaning and Maintenance
I cannot change
the fan speed.
The remote control
does not work.

Before fixing the installation plate to a wall and then
fixing the indoor unit to the installation plate, a window
frame, or a gypsum board, you must determine the
position of a hole (with 65 mm inner diameter) through
which the pipe bundle (consisting of power and
communication cables, refrigerant pipes, and drain hose)
will pass and then drill that hole.
1 Determine the position of a 65 mm hole in
consideration of the possible directions of the pipe
bundle and the minimum distances between the hole
and the installation plate.
2 Drill the hole.
CAUTION
• Be sure to drill only one hole.
• Make sure that the hole slants downwards so that the
drain hose slants downwards to drain water well.
Step 1.5 Taping the pipes, cables, and
drain hose
1 Wrap foam insulation on parts without insulation
on the ends of the refrigerant pipes, as shown in
the figure. This wrapping minimises condensation
problem.
CAUTION
• If changing the pipe direction from left to right,
do not drastically bent it but slowly turn it in the
opposite direction as shown. Otherwise, the pipe may
be damaged in the process.
2 Wind the refrigerant pipes, power cable,
communication cable and drain hose with vinyl tape
to make a pipe bundle.

sheathed flexible cord. (Code designation IEC: 60227
IEC53/CENELEC: H05VV-F, IEC: 60245 IEC 66/
CENELEC: H07RN-F, IEC: 60245 IEC 57/CENELEC:
H05RN-F)
• Power & Communication cable shall not exceed 30m.
CAUTION
• For the terminal block wiring, use a wire with a
ring terminal socket only. Regular wires without
a ring terminal socket may become a hazard due
to overheating of the electrical contact during
installation.
• If you need to extend the pipe, be sure to extend
the cable, too. The maximum length of each of the
cable and pipe used should not exceed 15 metres
(✴✴09/10/12/13✴✴), 20 metres(✴✴18/24✴✴ME/UN)
and 30 metres(✴✴18/24✴✴SS/TC).
• Do not connect two or more different cables to
extend the length. This connection may cause fire.
• Each circular terminal must match the size of its
corresponding screw in the terminal block.
• After connecting the cables, make sure that terminal
numbers on the indoor and outdoor units match.
• Ensure that power and communication cables are
separated, they must not be in the same cable.
WARNING
• Connect the wires firmly so that wires cannot be
pulled out easily. (If they are loose, it could cause
burn-out of the wires.)

Step 2.8 Installing and connecting
the assembly pipes to the refrigerant
pipes (assembly pipe)
Connect indoor and outdoor units with field-supplied
copper pipes by means of flare connections. Use
insulated seamless refrigeration grade pipe only,
(Cu DHP type according to ISO1337), degreased and
deoxidized, suitable for operating pressures of at least
4200 kPa and for burst pressure of at least 20700 kPa.
Under no circumstances must sanitary type copper pipe
be used.
There are 2 refrigerant pipes of different diameters:
• The smaller one is for the liquid refrigerant
• The larger one is for the gas refrigerant
A short liquid refrigerant pipe and a short gas
refrigerant pipe are already fitted to the air conditioner.
The connection procedure for the refrigerant pipes
varies according to the exit position of each pipe when
facing the wall:
CAUTION
• Make sure that the indoor unit is in upright position
when you pour water to check for leakage. Make sure
that the water does not overflow onto the electrical

• When installing, make sure there is no leakage. When
recovering the refrigerant, ground the compressor
first before removing the connection pipe. If the
refrigerant pipe is not properly connected and the
compressor works with the stop valve open, the pipe
inhales the air and it makes the pressure inside of
the refrigerant cycle abnormally high. It may cause
explosion and injury.
1 Leave the system in the standby mode.
WARNING
• Do not turn on the system! This is necessary for
better vacuum operation (full OPEN position of
Electronic Expansion Valve).
2 Connect the charging hose of the low pressure side
of manifold gauge to a gas service port as seen in the
picture.
Step 3.3 Evacuating the air
The outdoor unit is loaded with sufficient R-410A
refrigerant. Do not vent R-410A into atmosphere: it is a
fluorinated greenhouse gas, covered by Kyoto Protocol,
Installation
DB68-06039A-00.indd 46 5/25/2016 7:08:57 PM
with a Global Warming Potential (GWP) = 2088. You
should evacuate the air in the indoor unit and in the
pipe. If air remains in the refrigerant pipes, it affects the
compressor. It may cause reduction of cooling capacity
and malfunction. Use a vacuum pump.

gauge anticlockwise.
4 Evacuate the air in the connected pipes using the
vacuum pump for about 15 minutes.
• Make sure that pressure gauge shows -0.1 MPa
(-76 cmHg, 5 torr) after about 10 minutes. This
procedure is very important to avoid a gas leak.
• Close the valve of the low pressure side of
manifold gauge clockwise.
• Turn off the vacuum pump.
• Check for 2 minutes if there is any pressure
change.
• Remove the hose of the low pressure side of
manifold gauge.
5 Set a valve cork of liquid and gas service port to the
open position.
Step 3.4 Adding refrigerant
If you use a pipe longer than the length specified in
the piping codes and standards, you must add 15 g
of refrigerant R-410A for each extra meter. If you use
a pipe shorter than the length specified in the piping
codes and standards, the evacuating time is normal.
Refer to the Service Manual for further details.
NOTE
• If R-410A refrigerant is charged with gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
• During the measuring operation of refrigerant
quantity added use electronic scales. If cylinder
doesn't have siphon, upset it.
CAUTION
• The remaining air in the Refrigeration cycle, which
contains moisture, may cause malfunction on the
compressor.
• Always contact the service centre or a professional
installation agency for product installation.
R-410A is a mixed type of refrigerant. It is necessary for
recharging under conditions of liquid. When recharging
refrigerant from the refrigerant cylinder to the
equipment.
Before recharging, check whether the cylinder has
a siphon or not. There are two ways to recharge the
refrigerant:
