AUTOMATIC OPERATION
• Whenyouset the airconditionerin AUTO mode,itwill automatically
select cooling, heating (cooling/heating models only), or fan only
operation depending on what temperature you have selected and
the room temperature.
• Theairconditionerwillcontrolroomtemperatureautomaticallyround
the temperature point set by you.
• If the AUTO mode is uncomfortable, you can select desired conditions
manually.
ECONOMIC OPERATION
When you push SLEEP button during cooling, heating (cooling only
typewithout),orAUTOoperation,theairconditionerwillstartfollowing
operation. The fan speed will be automatically controlled. In the
operation suppression zone where capacity is kept to the minimum,
overcoolingispreventedbyraisingthetemperaturesettingby1°Cafter
1 hour and by 2°C after 2 hours of operation. The room temperature
isthusregulatedbetweentheoperationsuppressionzoneandtheset

DRYING OPERATION
• The dry mode will automatically select the drying operation based
onthe di erencebetweenthe settemperature andtheactual room

OPTIMALOPERATION
To achieve optimal performance, Please note the following:
• Ad ust the air ow direction correctly so that it is not directed on people.
•
Ad ust the temperature to achieve the highest comfort level. o not ad ust the unit to excessive temperature levels.
• Close doors and windows on COOLor EAT 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.
• o not put any ob ect near air inlet or air outlet, as the ef ciency of the air conditioner may be reduce and the air
conditioner may stop running.
• Clean the air lter periodically, otherwise cooling or heating performance may be reduced.
• o not operate unit with horizontal louver in closed position.
PREPARATION E ORE INSTALLATION
• efore doing any work, check the interior power supply cord and the main breaker capacity are suf cient and the
installation area is suf cient and complies with the re uirements.
• Check that the power supply available agrees with name plate voltage.
• Electrical work, wiring and cables must be performed in compliance with national and local wiring codes and
standard.
• o not use the extension cables. In the case extended cables are needed, use the terminal block.
SELECTION O THE LOCATION
• Select a place which provides the space around the units as shown in the diagram below.

■Piping
The auxiliary piping can be connected in the diections
shown the above diagram. To connect in the ", #and
$direction, 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.

■Drain hose
• Drain hose is flexible and can be routed to suit various
piping arrangements. The drain line must include elbow
trap (U bend). Connect a plastic condensate pipe with
an internal diameter of 12 mm.
• The drain hose can be connected to the left or the
right side.
Verification of condensate water drainage:
Fill the drain pan with water and observe evacuation.

• Piping must be performed by uali ed personnel
according to good refrigeration systems practices.
• Piping materials and insulation materials must be of
refrigerant uality.
• Select the pipe diameters according to the size of unit
and cut the pipe to design length by using pipe cutter.
• Install the are nuts and are the end of the pipes.
• Check that no foreign bodies are inside the piping.
• Align the central of the connecting pipes and tighten
the are nut.
• Fix piping with pipe clamps and check that any pipe
vibrations cannot be transmitted to the building
structure.
• Connect the pipe correctly.
• o not apply the excessive tor ue.
•
Use an appropriate bending tool to form curves and
avoid over tightening the refrigerant tubes.

To avoid alteration of unit capacities, check that piping
lengths and changes in elevation are kept to a strict
minimum.
efore connecting the refrigerant lines, follow the
procedures below (if pre charged connection lines are
not supplied):
Select copper pipe diameters according to the size of
unit to be installed.
Install the refrigeration lines, checking that no foreign
bodies get inside the piping.
Install the are connectors and are the ends of the
pipes.
Evacuate the piping. This operation, which should last
at least 15 minutes if there are large piping lengths
and changes in elevation, should be followed by a leak

If you plan to idle the unit for a long time, perform the following:
(1) Operate the fan for about half a day to dry the inside of the unit.
(2) Stop the air conditioner and disconnect power.
Remove the batteries from the remote controller.
(3) The outdoor unit re uires periodic maintenance and cleaning. o not
attempt to do this yourself.
Contact your dealer or servicer.

• Check that the wiring is not broken o or disconnected.
• Check that the air lter is installed.
• Check if the air outlet or inlet is blocked after the air conditioner
has not been used for a long time.

OPERATION TIPS
The following events may occur during normal operation.
P
Compressor protection
• The compressor cannot restart for 3 minutes after it stops.
Anti cold air (Cooling and heating models only)
• Theunitisdesignednotto blowcold airon EATmode,whentheindoorheatexchangerisin oneof thefollowing
three situations and the set temperature has not been reached.
A) When heating has ust starting.
) efrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running when defrosting (Cooling and heating models only).
efrosting (Cooling and heating models only)
• Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is
high resulting in lower heating ef ciency of the air conditioner.
• uring this condition air conditioner will stop heating operation and start defrosting automatically.
•
The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost
buildup on the outdoor unit.
A
• Awhite mistmaygenerate due toalarge temperature di erencebetween air inletandair outlet onCOOLmode
in an indoor environment that has a high relative humidity.
• Awhitemistmay generate duetomoisture generated fromdefrostingprocess when theairconditioner restarts in
EAT mode operation after defrosting.
L .
• ou may hear a low hissing sound when the compressor is running or has ust stopped running.
This sound is the sound of the refrigerant owing or coming to a stop.
•
ou can also hear a low s ueak sound when the compressor is running or has ust stopped running. This is
caused by heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
