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.
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.
• 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.
• 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.

Remote Control Unit (continued)
Using the Remote Control Unit
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.
If the remote control is located near a heat source, such as a space heater or in
direct sunlight, press the SENSOR button to switch to the sensor on the indoor unit.
Temperature Display Selector button This switches the temperature display between °C and °F.
Time Display Selector button This switches the time display between 24-hour time and 12-hour time.
ACL button (ALL CLEAR) Puts the remote control unit into pre-operation status. Always press this
button after replacing the batteries and setting the S/M switch.
ADDRESS switch • The address switch changes 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. For more information, please
contact the dealer where you made the purchase.
• Normally, the tabs on the remote control unit should not be bent.
S/M (Single/Multiple switch) • Initially, the S/M switch is set to S (Single).
• Set this switch to M (Multiple) for multiple operation.
• Always press ACL button by a thin object such as the tip of a pen after
setting the S/M switch.
When multiple indoor units are used and units in other rooms are already operating,
they will be set to the same mode of operation as the operating indoor units.
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 15 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.
How to Install Batteries
• The batteries last about six months, depending on how much you
use the remote control unit. Replace the batteries when the remote
control unit’s display fails to light, or when the remote control cannot
be used to change the air conditioner’s settings.
• Use two fresh leak-proof type-AAA alkaline batteries.
• In replacing batteries, follow the instructions as mentioned in the
sub-section “How to Install Batteries”.
• If you do not use the remote control unit more than 1 month, take out
the batteries.
NOTE
NOTE
NOTE
1. Slide the cover in the direction

speed is 1 step above “High”.
• HIGH POWER Mode cannot be used when the operation mode is
Automatic Operation.
• When set to High fan speed during heating operation, the
fan runs at High fan speed even though the mark is
displayed.
• Depending on the operating conditions, the fan speed may
be increased by a small amount only.

Special Remarks
How it works? • Once the room temperature reaches the level that was set, the unit’s
operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower speed for
providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 15 °C or less.
Heating performance • Because this air conditioner heats a room by drawing in 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 together with it.
Defrosting • When the outdoor temperature is low, frost or ice may form on the heat
exchanger coil, reducing heating performance. When this happens, a
microcomputer defrosting system operates. At the same time, the fan on
the indoor unit stops and the OPERATION lamp lights red and orange
alternately until defrosting is completed. Heating operation restarts after
several minutes. (This interval will vary slightly depending upon the
outdoor temperature and the way in which frost forms.)
Cold draft prevention • For several minutes after the start of heating operation, the indoor fan runs
at a lower speed until the indoor heat exchanger coil has warmed up
sufficiently. However, the fan may remain stopped when the room
temperature is low. This is because the COLD DRAFT PREVENTION
SYSTEM is in operation.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically within five minutes by the
remote control unit.
Clicking sound is heard from
the air conditioner
• In heating or cooling operation, any plastic parts may expand or shrink due
to a sudden temperature change. In this event, a clicking sound may occur.
This is normal, and the sound will soon disappear.
• The remote control unit sends the setting condition to the air conditioner
regularly at five minute intervals.
