•Air Sweep Control

This function moves a flap up and down in the air outlet, directing air in a sweeping motion around the room and providing comfort in every corner.

•Auto. Flap Control

This automatically sets the flap to the optimum position during heating, cooling, and drying operation.

•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 temperature setting.

•Hot Start Heating System

Right from the start, the air is warm and comfortable. This system prevents any cold blasts at the beginning while the heat pump is warming up, or even defrosting.

Alert Symbols

The following symbols used in this manual, alert you to potentially dangerous conditions to users, service personnel or the appliance:

This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.

CAUTION

This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.

OI-802-3EG	3

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 heatgenerating 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.
CAUTION
		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)

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 SENSOR button to switch to the sensor on the indoor unit.

Temperature Display Selector This switches the temperature display between °C and °F. button

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.

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.

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 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.
