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.
•The unit may malfunction when the receiver in the indoor unit is
exposed to the inverter lamp light.
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.
•Power supply: 60 Hz, single-phase, 230/208 volts.
CAUTION
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 touch the unit with wet hands.
•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.
CAUTION •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 the room too much if babies or invalids are present.
To warm up the system, the power mains
must be turned on at least five (5) hours
before operation. Leave the power mains
ON unless you will not be using this
appliance for an extended period.

Remote Control Unit (continued)
NOTE •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.
•Operation when the outdoor temperature is low
If an indoor unit connected to a ‘‘CL-’’ type outdoor unit is operating in
the cooling mode during the winter months when the outdoor
temperature is low, setting the FAN SPEED selector to (low fan speed)
can result in intermittent operation to prevent freezing. In such cases,
use the (high fan speed) or (medium fan speed) setting instead.

power failure, the unit will stop. When the power is restored, the unit
will restart automatically after three minutes.
2. Adjusting the
Fan Speed
A. Automatic Simply set the FAN SPEED selector to the position.
A microcomputer in the air conditioner automatically controls the fan speed
when the mode is selected. When the air conditioner starts operating,
the difference between the room temperature and the set temperature is
detected by the microcomputer which then automatically switches the fan
speed to the most suitable level.
Cooling mode:
When difference between room
temperature and set temperature is FAN SPEED
4 °F and over High
Between 4 °F and 2 °F Medium
Below 2 °F Low
NOTE The above table assumes that the sensor on the remote control is being
used. If the sensor on the indoor unit is being used (the indicator is on),
actual operation may differ slightly from the operation described in the
table.
(Refer to ‘‘A/C SENSOR button’’ on page 10.)
