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.

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.

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.

• 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.

Wireless Remote Control Unit (Optional parts)

Parts Name and Functions

NOTE

The illustration above pictures the wireless remote control unit after the cover has been lowered and removed.

NOTE

• The wireless remote control unit sends the temperature signal to the air conditioner regularly at five-minute intervals. If the signal from the wireless remote control unit stops for more than ten minutes due to the loss of the wireless 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 wireless remote control unit may differ from the temperature detected at the air conditioner’s position.
• When low fan speed is selected and the air conditioner is in cooling operation at a low outdoor temperature of less than 50°F, the air conditioner may automatically switch to medium fan speed to prevent freezing.

Receiver

The signal receivers with the exception of the separately installed signal receiver are mounted on the indoor units.

• If two beeps are heard, the operation lamp among the indication lamps has lighted and the timer lamp and standby lamp blink alternately in cases where heat pump models are used, this indicates a cooling/heating mode mismatch and, as such, operation in the desired mode cannot be performed. (The same beeps will be heard and the same operation lamps will light when auto cooling/heating has been selected on a model which does not have the auto cooling/heating function.)
• When local operation has been set to disable because the centralized control mode is established, for instance,
  pressing the ON/OFF operation button, MODE button or temperature setting buttons results in the sounding of five beeps, and the attempted change in the operation will not be accepted.

Operation

Using the Wireless Remote Control Unit

Slide switch

This is used to set the operation mode of the indoor units and to set the flaps.

• Depending on the indoor unit used, the operation display and airflow direction display settings will differ as shown below.

• Use a pointed implement to change the switch position.

• When the switch position has been changed, press the ACL button.

• For details on the flap functions, refer to the operating instructions of the indoor unit used.

  • Before use, check that the slide switch has been set to the position shown in the figure above. For details on how to set the slide switch, consult your dealer.

How to install batteries

1. Slide the cover in the direction indicated by the arrow and remove it.
2. Install two AAA alkaline batteries. Make sure the batteries point in the direction marked in the battery compartment.
3. Use a pointed implement to press the ACL button.

• The batteries last about a year, depending on how much you use the wireless remote control unit. Replace the
  batteries when the wireless remote control unit’s display fails to light, or when the remote control cannot be used to change the air conditioner’s settings.

• When the batteries are to be replaced, make sure that both batteries are new and that the same kind of battery is used.

• Remove the batteries if the wireless remote control unit is not going to be used for a prolonged period.

• Dispose of the used batteries at the designated location.

How to use the wireless remote control unit

• Point the wireless remote control unit’s transmitter at the signal receiver. If the signal is received properly, a beep is heard. (Two beeps are heard only when operation starts up.)
• Signals can be received over a distance of approximately 26 ft. This distance is approximate: it may be slightly more or less depending on how much charge remains in the batteries and on other factors.
• Ensure that the signals will not be blocked by any objects positioned between the transmitter and signal receiver.
• Avoid placing the wireless remote control unit where it will be exposed to direct sunlight or in the direct path of the air blown out from the air conditioner, near a heating appliance, etc.
• Do not drop, throw or wash the wireless remote control unit.
• Signal reception may not be accepted in rooms with fluorescent lights that use the electronic instantaneous lighting system (rapid start system) or inverter system. For further details, contact your dealer.

When mounting the wireless remote control unit on a wall for use

• Before mounting the wireless remote control unit on the wall, place the unit at the mounting position, press the ON/OFF operation button and check that the signals are received properly.
• To remove the wireless remote control unit, disengage it by pulling it toward you.

Operating tips

• Do not operate the wireless remote control unit too far away from the signal receiver.
  Doing so may cause operational errors.
  Make absolutely sure that the wireless remote control unit and signal receiver are both in the same room.

• When operating the wireless remote control unit, point it directly at the signal receiver.
  A beep is heard when a signal is received properly.

• Avoid places where the wireless remote control unit will be obscured by curtains, etc.
  Remove it before operation.

Address Settings

When a multiple number of indoor units that can be operated by the wireless remote control unit have been installed in the same room with a multi-unit or single-unit installation, this button enables addresses to be set in order to prevent the sending of signals to the wrong indoor unit. Each of up to six indoor units can be controlled separately using its own wireless remote control unit by matching the number of the address switch on the operation area of the indoor unit and the number used for the address of its wireless remote control unit. (The indoor units cannot be controlled separately when they are used in a flexible combination format, simultaneous operation of multi units format or any other such format since they will all operate at the same time.) The signal receiver has an address switch for signal reception, and the wireless remote control unit has an address switch for signal transmission.

How to check the addresses

When the ADDRESS button on the wireless remote control unit is pressed, the current address appears on the wireless remote control unit’s display. The buzzer sounds if the address displayed matches the signal receiver’s address. (The buzzer always sounds if “ALL” appears as the address display.)
If “ALL” appears as the address display, operations can be performed irrespective of the signal receiver’s address. Point the wireless remote control unit at the signal receiver of the unit to be operated, and send the signal.

How to set the matching address

Wireless remote control unit’s address setting

1. When the ADDRESS button is held down for 4 or more seconds, “ ” lights on the wireless remote control unit’s display, and the current address blinks.

2. Each time the ADDRESS button is now pressed, the address changes by one setting in the following sequence: ALL → 1 → 2 → 3 … → 6 → ALL.
   Select the setting which matches the setting of the address switch in the operation area of the indoor unit to be operated.

3. When the SET button is now pressed, the address stops blinking and lights instead, and it remains on the display for 5 seconds.
   The buzzer sounds if the setting matches the setting of the address switch in the operation area of the indoor unit.

NOTE

When the batteries are replaced, the address setting returns to “ALL”.

Emergency Operation

In any of the following events, use the Emergency operation button to operate the air conditioner on a makeshift basis.

• When there is no charge remaining in the wireless remote control unit’s batteries
• When the wireless remote control unit has failed
• When the wireless remote control unit has been lost or misplaced

A, U, D type Initiate operation using the Emergency operation button in the signal receiver.

Troubleshooting

Check out the following points before requesting service.

If the trouble persists even after performing the checks recommended above, shut down the air conditioner’s operation, set the local power switch to OFF, and contact your dealer with the model number and trouble symptoms. You must NOT attempt to make repairs yourself due to the dangers involved. If one or more of the indication lamps is blinking, give this information to the dealer as well.

Adjusting the Airflow Direction

♦ Semi-concealed type

Hold the flap and move it up and down to adjust the direction of the airflow.
When the flap moves, the line engraved on the rim of the disc will move up and down.

In the cool mode, manually adjust the angle of the flap so that the indicator is in line with the blue rectangular mark on the label.

Otherwise, condensation may drip onto the floor.

In the heat mode, adjust the flap so that the indicator is in line with the red rectangular mark.
