Caution Statements
1.We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the installation
instructions provided with the unit.
WARNING
2.Before installation, check if the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
WARNING
3.Do not install the air conditioner where there are fumes or flammable
gases, or in an extremely humid space such as a greenhouse.
4.Do not install the air conditioner where excessively high heat-
generating objects are placed.
To protect the air conditioner from heavy corrosion, avoid installing the outdoor
Avoid:
unit where salty sea water can splash directly onto it or in sulphurous air near a
spa.
1.All wiring must conform to the local electrical codes.
2.Each unit must be properly grounded.
3.Wiring must be done by a qualified electrician.
4.Consider the capacity of the electric current of your electrical kilowatt-
hour meter wires and socket before installation.
5.Power for this air-conditioner is supplied by individual electrical wire.
6.There must be at least one ventilation intake in the area where the
heat-pump is mounted.
1.Read this manual carefully before using this air conditioner. If you still have
any diffculties or problems, consult your dealer for help.
2.The air conditioner is designed to give you comfortable room conditions.
Use this only for its intended purpose as described in this instruction
manual.
WARNING
3.Never use store gasoline or other flammable vapor or liquid near the
air conditioner - it is very dangerous.
4.The air conditioner has no ventilator for intaking fresh air from
outdoors. You must open doors or windows frequently when you
use gas or oil heating appliances in the same room, which consume
a lot of oxygen from the air. Otherwise there is a risk of suffocation
in an extreme case.
1.Do not turn the air conditioner on and off from the power mains
switch. Use the ON/OFF operation button.
CAUTION
2.Do not stick anything into the air outlet of the outdoor unit. This is
dangerous because the fan is rotating at high speed.
3.Do not let the children play with the air conditioner.
4.Do not cool or heat the room too much if babies or invailds are
present.

indoor unit.
NOTE
!
Automatic switching between cooling and heating
This unit automatically switches between cooling operation and heating operation according to the difference
between the room temperature and the set temperature.
The remote control unit sends the temperature signal to the air conditioner regularly at three
NOTE
minute intervals. If the signal from the remote control unit stops for more than ten minutes due
to the loss of the remote control unit or other trouble, the air conditioner will switch to the
temperature sensor which is built into the indoor unit and control the room temperature. In
these cases, the temperature around the remote control unit may differ from the temperature
detected at the air conditioner,s position.

Adjusting the Airflow Direction
1. Horizontal
The horizontal airflow can be adjusted by moving the vertical vanes with your hands to the
left or right.
When the humidity is high, the vertical vanes should be in the front
position during the cooling or dehumidifying operation. If the vertical
vanes are positioned all of the way to the right or left, condensation may
begin to form around the air vent and drip down.
CAUTION
!
2. Vertical
The vertical airflow can be adjusted by moving the flap with the remote control unit Do not
move the flap with your hands.Confirm that the remote control unit has been turned on.

Special Remarks
Heating (
) Operation
Heating performance
● Because this air conditioner heats a room by drawing on the heat of the outside air
(heat pump system), the heating efficiency will fall off when the outdoor temperature
is very low. If sufficient heat cannot be obtained with this air conditioner, use another
heating appliance in conjunction with it.
●When the outdoor temperature is low, frost or ice may from in the heat exchanger
coil, reducing heating performance. When this happens, a microcomputer defrosting
system will operate. At the same time the fan on the indoor unit stops ( or runs at
very low speed in some cases). Heating operation restarts after several minutes.
(This interval will vary slightly depending upon the outdoor temperature and the way
in which frost forms).
Defrosting
POWER lamp
●For several minutes after the start of heating operation, the indoor fan will not start
running until the indoor heat exchanger coil has warmed up sufficiently. This is
because the COLD DRAFT PREVENTION SYSTEM is operating.
●The POWER lamp also remains lit during defrosting or when the compressor has
been turned off by the thermostat when the system is in the heating mode.
●In the event of power failure, the unit will stop. When the power is resumed,
Power failure
during operation
the unit will restart automatically after three minutes.
●In heating or cooling operation. Some plastic parts may expand of shrink due to a
sudden temperature change. In this event, a clicking sound may occur. This is normal,
and the sound will soon disappear.
Clicking Sound
Clicking sound is
heard from the air
conditioner
●The remote control unit sends the temperature signal to the air conditioner regularly
at three-minute intervals. If the signal from the remote control unit stops for more
than ten minutes due to the loss of the remote control unit or other trouble, the air
conditioner will switch to the temperature sensor which is built into the indoor unit
and control the room temperature. In these cases, the temperature around the
remote control unit may differ from the temperature detected at the air conditioner’s
position.

NOTE
Care and Cleaning
1.For safety, be sure to turn the air conditioner off and also to disconnect
the power before cleaning.
2.Do not pour water on the indoor unit to clean it. This will damage the
internal components and cause an electric shock hazard.
WARNING
!
Clean the casing and grille of the indoor unit with a vacuum cleaner brush, or
wipe them with a clean, soft cloth.
If these parts are stained, use a clean cloth moistened with a mild liquid
deteraent. When cleaning the grille, be careful not to force the vanes out of
place.
1.Never use solvents, or harsh chemicals when cleaning the indoor unit.
Do not wipe the plastic casing using very hot water.
2.Some metal edges and the fins are sharp and may cause injury if
handled improperly; be especially careful when you clean these parts.
3.The internal coil and other components of the outdoor unit must be
cleaned every year.Consult your dealer or service center.
CAUTION
!

Tips for Energy Saving
Do not
●Block the air intake and outlet of the unit. If they are obstructed, the unit
will not work well, and may be damaged.
●Let sunlight directly into the room. Use sunshades, blinds or curtains.
If the walls and ceiling of the room are warmed by the sun, it will take
longer time to cool the room.
●Always try to keep the air filter clean. (Refer to“Care and Cleaning”.)A
clogged filter will impair the performance of the unit.
●To prevent conditioned air from escaping, keep windows, doors and any
other openings closed.
