Installation Location
•We recommend that this air conditioner be installed properly by
qualified installation technicians in accordance with the Installation
Instructions provided with the unit.
•Before installation, check that the voltage of the electric supply in your
home or office is the same as the voltage shown on the nameplate.
•Do not install this air conditioner where there are fumes or
flammable gases, or in an extremely humid space such as a
greenhouse.
•Do not install the air conditioner where excessively high heat-
generating objects are placed.
Avoid: To protect the air conditioner from heavy corrosion, avoid installing the
outdoor unit where salty sea water can splash directly onto it or in
sulphurous air near a spa.
Electrical Requirements
1. All wiring must conform to the local electrical codes. Consult your
dealer or a qualified electrician for details.
2. Each unit must be properly grounded with a ground (or earth) wire or
through the supply wiring.
3. Wiring must be done by a qualified electrician.
Safety Instructions
•Read this Instruction Manual carefully before using this air
conditioner. If you still have any difficulties or problems, consult your
dealer for help.
•This air conditioner is designed to give you comfortable room
conditions. Use this only for its intended purpose as described in this
Instruction Manual.
•Never use or store gasoline or other flammable vapor or liquid near
the air conditioner – it is very dangerous.
•This 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.
•Do not turn the air conditioner on and off from the power mains
switch. Use the ON/OFF operation button.
•Do not stick anything into the air outlet of the outdoor unit.This is
dangerous because the fan is rotating at high speed.
•Do not let children play with the air conditioner.
•Do not cool or heat the room too much if babies or invalids are
present.

ADDRESS switch •Change the address switch to prevent mixing of signals from remote
control units when two air conditioners are installed next to each other.
Normally, the address switch is set to A. When switching the adress, take
the steps listed below. Contact your dealer where you made the
purchase if 3 or more air conditioners are to be operated.
1Break off the address switching tabs on the remote control unit, and
set the address switch to B.
2Insert batteries into the remote control unit, press the ACL button,
and attach the cover.
3Open the intake grille of the indoor unit, and set the operation knob
to the DEMO position.
4Press the ON/OFF operation button on the remote control unit, and
check that a receiving tone (beep) is heard from the indoor unit.
5Set the operation selector to the ON position, and close the intake
grille.
6Operate the remote control unit, and check that a receiving tone
(beep) is heard from the indoor unit.
•Normally, the tabs on the remote control unit should not be bent.
A/C SENSOR button When you press this button (use a small-tipped object such as a
ballpoint pen), the mark will appear at the display. And the room
temperature is detected by the sensor which is built into the indoor unit
and the air conditioner is controlled accordingly.
NOTE If the remote control is located near a heat source, such as a space heater
or in direct sunlight, press the A/C SENSOR button to switch to the sensor
on the indoor unit.
NOTE The remote control unit sends the temperature signal to the air conditioner regularly at five 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.

STEP 1 Press the MODE selector button and select (AUTO).
STEP 2 Press the ON/OFF button and switch the air conditioner ON.
STEP 3 Press the temperature setting buttons (TEMP.).
The air conditioner starts operating after automatically selecting the type of operation
—whether heating, drying (dehumidifying) or cooling—that suits the conditions in the
room, and automatically adjusting the temperature, fan speed and airflow direction.
Each time one of the temperature setting buttons (TEMP.) is pressed, the temperature is
changed by 1 °C.
The temperature can be changed from +4 °C (higher) to
–4 °C (lower) from the standard temperature setting.
(The upper limit during cooling is 30 °C.)

As shown in the figure below, the automatic selection of the operating modes
is determined by the indoor temperature and outside air temperature.
•When multiple indoor units are used and units in other rooms are already operating,
they will be set to the same type of operation as the operating indoor units.
•The temperature, airflow direction and fan speed are set automatically but the airflow
direction and fan speed can be changed to suit your individual preference. It will take
a few seconds for the fan speed to be switched.
2. Manual Operation
NOTE Check that the circuit breaker on the power panel is turned on and that
the operation selector of the indoor unit is in the ON position.

Operation with the Remote Control Unit (continued)
•After the cooling or drying operation has stopped, the indoor fan runs
for about 30 seconds to dry out the inside of the air conditioner. (The
operating lamps remain off.) The flap closes after the fan has
stopped.
•If the room temperature rises above the temperature setting during a
drying operation, the unit performs similar operation to cooling, and
when the room temperature approaches the temperature setting, it
performs the humidity-priority drying operation.
•The drying operation does not serve to raise the room temperature.
(When the outside air temperature is low or when the heat quantity
inside the room is low, the room temperature will not rise.)
•A change made to the temperature setting remains stored in the
memory even after operation has stopped.
•If the temperature setting is lowered during a drying operation so that
the unit has switched to a cooling operation, the outdoor unit shuts
down for 3 minutes. (This happens only when one indoor unit is
used.)
•When the unit is running in the drying operation mode while the
temperature setting is higher than the room temperature, the
humidity may not be reduced. In a case like this, select a temperature
setting which is lower than the current room temperature, and
perform the drying operation.
NOTE This appliance has a built-in 3-minute time delay circuit to ensure reliable
operation. When the operation button is pressed, the compressor will
start running within three minutes. In the event of power failure, the unit
will stop.
STEP 1 Press the MODE selector button and select the desired
mode.

16 °C min.
NOTE •Room temperature control works to ensure that the
temperature stabilizes within a range of ±2 °C of the
temperature setting. For this reason, the value displayed
on the remote control unit may differ from the actual
temperature setting. Before the temperature stabilizes,
this difference may exceed the ±2 °C range.
•The operating lamp of the indoor unit lights in one of the
colors shown below.
STEP 4 Set the FAN SPEED selector button to the setting you want.
(Refer to “Adjusting the Airflow Direction”on page 23.)

When the ECONOMY mode is selected, the air conditioner
automatically raises the temperature setting 1 °C when 60 minutes
have passed after the selection was made. This enables you to save
energy without sacrificing comfort. This function is convenient when
gentle cooling is needed.
When the ECONOMY mode is selected, the air conditioner
automatically lowers the temperature setting 3 °C when 60 minutes
have passed after the selection was made, and then another 4 °C after
another 2 hours have passed, regardless of the indoor temperature
when ECONOMY was selected. This enables you to save energy
without sacrificing comfort. This function is convenient when gentle
heating is needed.
