1. PRECAUTIONS FOR SAFETY

DANGER

• Do not attempt to install this unit by yourself. This unit requires qualified installer.

• Do not attempt to repair the unit by yourself. This unit has no components which you can repair.

• Opening or removing the cover will expose you to dangerous voltage.

• Turning off the power supply will not prevent potential electric shock.

WARNING

WARNINGS ABOUT INSTALLATION

• Make sure to ask the qualified installation professional in electric work to install the air conditioner. If the air conditioner is inappropriate installed by yourself, it may cause water leak, electric shock, fire, and so on.

• Be sure to connect ground wire. (grounding work) Incomplete grounding cause an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.

• If you install the indoor unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement the measures. Accumulation of highlyconcentrated refrigerant may cause an oxygen deficiency accident.

• Check whether the piping work has been properly completed. When existing pipes are used and if they are not constructed properly, the refrigerant gas may leak. Contact the installation company and confirm that the piping work has been properly completed. For details of installation of the air conditioner, refer to the Installation Manual. Use tools and piping materials for R410 only. Failure to do so or improper installation may cause a burst of pipe, resulting in injury.

Owner’s Manual

WARNINGS ABOUT OPERATION

• Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it.

• Avoid cooling the room too strong or exposing the human body to cool breeze for a long time as it is bad for the health.

• When you notice something abnormal with the air conditioner (smells like something scorching, poor cooling, etc.), immediately turn off the main switch, the circuit breaker, from the mains to stop the air conditioner, and contact the dealer.

–2–

2-EN

High-Wall Type

Owner’s Manual

If the air conditioner is continuously operated with something abnormal, it may cause machine failure, electric shock, fire, and so on.

WARNINGS ABOUT MOVEMENT AND REPAIR

• When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the air conditioner as refrigerant leakage is considered as the cause. In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair. The refrigerant used in the air conditioner is harmless. Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in the room catches fire, it may generate toxic gas. When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been completely repaired.

• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock when removing the cover and main unit.

• Whenever the air conditioner needs repair, make sure to ask the dealer to do it. If it is repaired imperfectly, it may cause electric shock or fire.

• When moving the air conditioner for re-installing at another place, ask the dealer to do it. If it is

imperfectly installed, it may cause electric shock or fire.

CAUTION

CAUTIONS ABOUT INSTALLATION

• Use an exclusive power circuit for the air conditioner. Use the rated voltage.

• Certainly lay the drain hose for perfect draining. Wrong drainage may cause flooding in the house and getting furniture wet.

• Make sure to connect the air conditioner to an exclusive power supply of the rated voltage; otherwise, the unit may break down or cause a fire.

• Do not install the unit in a place where inflammable gas may leak. If inflammable gas accumulates around the unit, it may cause a fire.

CAUTIONS ABOUT OPERATION

• Carefully read this manual before starting the air conditioner. The manual includes many important things for daily operation.

• Do not use this air conditioner for other purposes such as preserving food, precision instruments, art objects, breeding animals, growing potted plants, etc.

• Do not install this air conditioner in a special-purpose room such as a ship or any kind of vehicle, otherwise it deteriorates the machine performance.

• When the air conditioner is operated together with a combustion appliance in the same place, be careful of ventilation to let fresh air into the room. Poor ventilation causes oxygen shortage.

3-EN

–3–

High-Wall Type

• When the air conditioner is used in a closed room, be careful of sufficient ventilation of the room. Poor ventilation causes oxygen shortage.

• Do not touch operation button with wet finger; otherwise, you may get an electric shock.

• Do not place any combustion appliance in a place where it is directly exposed to wind of the air conditioner; otherwise, it may cause imperfect combustion.

• When the air conditioner won’t be used for a considerably long time, turn off the main switch or the circuit breaker, for safety. Disconnection from the power supply prevents the unit from lightning and power source surge.

• Do not put a vessel with water such as a vase on the unit, because water may possibly sink into the unit and will bring about electric shock because of deterioration in electric insulation.

• Do not wash the unit with water. It may cause an electric shock.

• Do not use alcohol, benzene, thinner, glass cleaner, polishing powder, etc. for cleaning the unit, because they deteriorate or damage the air conditioner.

• When cleaning the unit, make sure to turn off the main switch or circuit breaker beforehand for preventing you from getting injured by the electric fan running inside. For details of cleaning method, refer to “Maintenance”.

• To make the air conditioner demonstrate its original performance, operate it within the range of the operating temperature specified in the instructions. Otherwise it may malfunction, break down or water may leak from the unit.

• Do not put anything on the outdoor unit or step on it. If you do, the unit may topple over or you may get injured.

2. SYSTEM CHARACTERISTICS

Air conditioner operating conditions

For proper performance, operate the air conditioner under the following temperature conditions:

Outdoor temperature : 23 °F to 109.4 °F (-5 °C to 43 °C) *

Cooling operation

Dry operation

Heating operation

*: The air conditioner can be operate when outside temperature is 5°F to 23°F (-15°C to -5°C). Installing

wind baffle to the outdoor unit is necessary to operate the air conditioner in that outside temperature range. For further details, refer to the installation manual of the outdoor unit.

If air conditioner is used outside of the above conditions, safety protection may work.

Room temperature :

[CAUTION]

Outdoor temperature : 59 °F to 109.4 °F (15 °C to 43 °C) Room temperature : 62.6 °F to 89.6 °F (17 °C to 32 °C) Outdoor temperature : -4 °F to 59 °F (-20 °C to 15 °C) (Wet bulb temperature) Room temperature : 59 °F to 86 °F (15 °C to 30 °C) (Dry bulb temperature)

Room relative humidity – less than 80 %. If the air conditioner operates in excess of this figure, condensation may occurs on the surface of the air conditioner.

3 minute protection function

There is a 3-minute time delay between compressor starts.

69.8 °F to 89.6 °F (21 °C to 32 °C) (Dry bulb temperature), 59 °F to 75.2 °F (15 °C to 24 °C) (Wet bulb temperature)

Auto restart

The unit will stop after a power failure.

• The unit will restart automatically in the same operating mode as before the power failure when the power is restored.

Fan operation Heating

• When there is a call for heating, the fan will not start right away. There is a delay of approximately 5 minutes to ensure that the indoor heat exchanger warmed up.

• When the room temperature reaches the set temperature, the fan will run at ultra low speed to avoid blowing cold air on the occupants in the space.

Cooling

When the room temperature reaches the set temperature, the fan will run at ultra low speed.

Defrost

When the unit is operating in the heating mode frost forms on the outdoor heat exchanger. When this occurs, defrost is initiated automatically. During the defrost period (2 to 10 minutes) both the indoor and outdoor units stop running.

• A hissing noise might be heard when the defrost cycle is initiated.

• During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit.

Heating capacity

In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is called heat pump system. When the outside temperature is too low, it is recommended to use another heating apparatus in combination with the air conditioner.

Attention to snowfall and freeze on the outdoor unit

• In snowy areas, the air inlet and air outlet of the outdoor unit are often covered with snow or frozen up. If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming.

• In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming.
