CAUTIONS
1. If air conditioner is used outside of the above conditions,
certain safety protection features may come into
operation cause the unit to function abnormally.
2. Room relative humidity less than 80%. If the air
conditioner operates in excess of this figure, the surface of
the air conditioner may attract condensation. Please sets
the vertical air flow louver to its maximum angle (Vertically
to the floor), and set HIGH fan mode.
3. Optimum performance will be achieved within these
operating temperature.

MANUAL OPERATION
1Open and lift the front panel up to an angle at which it
remains fixed with a clicking sound.
2Press the button until the AUTO indicator is lit, the unit
will work in forced AUTO mode.
3Close the panel firmly to its original position.
Manual operation can be used temporarily in case you can not find the remote controller or its batteries are
exhausted.
HOW THE AIR CONDITIONER WORKS
■AUTOMATIC OPERATION
•When you set the air conditioner in AUTO mode, it will
automatically select cooling, heating (cooling/heating
models only), or fan only operation depending on
what temperature you have selected and the room
temperature.
•The air conditioner will control room temperature
automatically around the temperature point set by you.
•If the AUTO mode is uncomfortable, you can select desired
conditions manually.
■SLEEP OPERATION
•When you push SLEEP button during cooling, heating
(cooling only type without), or AUTO operation, the
air conditioner will automatically increase (cooling) or
decrease (heating) 1°C per hour. The set temperature
will be steady 2 hours later.
•The fan speed will be automatically controlled.
■DRYING OPERATION
•The dry mode will automatically select the drying
operation based on the difference between the set
temperature and the actual room temperature.
•The temperature is regulated while dehumidifying by
repeating turning on and off of the cooling operation or fan
only. The fan is low.

OPTIMAL OPERATION
To achieve optimal performance, please note the following:
•Adjust the air flow direction correctly so that it is not directed on people.
•Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature
levels.
•Close doors and windows on COOL or HEAT modes, or performance may be reduced.
•Use TIMER ON button on the remote controller to select a time you want to start your air conditioner.
•Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air
conditioner may stop running.
•Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
•Do not operate unit with horizontal louver in closed position.
PREPARATION BEFORE INSTALLATION
•Before doing any work, check the interior power supply cord and the main breaker capacity are sufficient and the
installation area is sufficient and complies with the requirements.
•Check that the power supply available agrees with nameplate voltage.
•Electrical work, wiring and cables must be performed in compliance with national and local wiring codes and
standard.
•Do not use the extension cables. In the case extended cables are needed, use the terminal block.
SELECTION OF THE LOCATION
•Select a place which provides the space around the units as shown in the diagram below.

Note:
Connect the auxiliary pipe
of the three indoor units to
the stop valves as identified
with their respective matched
numbers A1, A2, and B on the
outdoor unit. After finishing
connection, the indoor units
must be marked relative
number A1, A2 and B.
Model 27-30
NOTE: At least two of A, B, C aspect are free from
blocking.
The air conditioner can be connected only to a supply
with system impedance no more than 0.26 ohm. In case
necessary please consult your supply authority for system
impedance information.
■ Cautions on remote controller installation
•Before installation, operate the remote controller to
determine its location in a reception range.
•Keep the remote controller at least 1 m apart from the
nearest TV set or stereo equipment.
•Do not install the remote controller in a place exposed
to direct sunlight or close to a heating source, such as a
stove.
•Note that the positive and negative poles are right
positions when loading batteries.

INSTALLATION PROCEDURE
■Fixing
•Place the installation guide pattern on the designated
installation place and mark the hole position.
•Drill a hole and mount installation plate.
ø 65 mm
• Make 6 mm 4-6 holes, in the wall at the four corners of
mounting plate (bracket) then insert appropriate mounting
devices.
• Install the mounting plate using 4-6 pieces of mounting
screw securely at four corners and tighten the screw
completely. Do not over tighten the screws and deform
the back plate.
Outdoor
Indoor
Note: When installing
the refrigerant pipes from
others side. A hole must be
place to allow fall
towards the outdoor unit.
•Be careful when handling the sharp edge of the
mounting plate.
•After determining the pipe
hole position drill the hole
at a slight downward slant
towards the outdoor side.
■Piping
The auxiliary piping can be connected in the directions
shown the above diagram. To connect in the D, Eand
Fdirection, pipes will need to be extended.
•Bend pipes carefully to avoid flattening or obstructing
them if the pipes are bent incorrectly, the indoor unit
may be unstable on the wall.
•Carefully arrange pipes so that pipes do not stick out
of the rear plate of the indoor unit.
•Never modify the unit by removing any of the safety
guards or by passing any of the safety interlock
switches.
•Connect the interconnecting cable correctly and con-
nect the connecting cable to terminal as identified with
their respective marking.
•Do not damage the conductor core or inner insulation
of power supply cables and do not deform or crush
the cables.
