  Doing so can result in discoloration and failure. To remove heavy stains, soak a cloth in neutral detergent mixed with water, wring it out thoroughly, wipe the stains off, and wipe again with a dry cloth.

• Never block or cover the indoor or outdoor unit’s intakes or outlets. Tall items of furniture underneath the indoor unit, or bulky items such as large boxes placed close to the outdoor unit will reduce the unit’s efficiency.

• Do not direct the airflow at plants or caged pets.

• Ventilate the room frequently. If the unit is operated continuously in a closed room for a long period of time, the air will become stale.

• To reduce the risk of injury, do not sit, stand, or place objects on the unit.

• Do not operate the unit with the panels and guards removed.
  – Rotating, hot, or high-voltage parts may cause injury, electric shock, or fire.

• Do not turn off the power immediately after stopping operation.
  – Wait for at least five minutes after the unit has stopped before turning off the power.
  – Failure to do so may cause failure of the unit or water leakage, allowing water to enter the room and damage the interior.

• Do not install the unit over things that are vulnerable to water damage from condensation dripping.

• Do not touch fans, heat exchanger fins, or the sharp edges of components with bare hands.
  – Doing so may result in injury.

• To reduce the risk of fire or electric shock due to dust entering the unit, do not use damaged filters or operate the unit without attaching filters.

In case of failure
Warning:

• Never remodel the air conditioner. Consult your dealer for any repair or service. Improper repair work can result in water leakage, electric shock, fire, etc.
• If the remote controller displays an error indication, the air conditioner does not run, or there is any abnormality, stop operation and contact your dealer. Leaving the unit as it is under such conditions can result in fire or failure.
• If the power breaker is frequently activated, get in touch with your dealer. Leaving it as it is can result in fire or failure.
• If the refrigeration gas blows out or leaks, stop the operation of the air conditioner, thoroughly ventilate the room, and contact your dealer. Leaving the unit as it is can result in accidents due to oxygen deficiency.

When the air conditioner is not to be used for a long time

• If the air conditioner is not to be used for a long time due to a seasonal change, etc., run it for 4 – 5 hours with the air blowing until the inside is completely dry. Failing to do so can result in the growth of unhygienic, unhealthy mold in scattered areas throughout the room.
• When it is not to be used for an extended time, keep the power supply turned OFF. If the power supply is kept on, several watts or several tens of watts will be wasted. Also, the accumulation of dust, etc., can result in fire.
• Keep the power switched ON for more than 12 hours before starting operation. Do not turn the power supply OFF during seasons of heavy use. Doing so can result in failure.

1.3. Disposing of the unit
Warning:

• When you need to dispose of the unit, consult your dealer. If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environment.

Names and functions of various parts

 How to operate

3.1. Turning ON/OFF

Press the [ON/OFF] button.
The ON/OFF lamp will light up in green, and the operation will start.

• The unit will operate with the previouslyset operation mode, set temperature, and fan speed.

Press the [ON/OFF] button again.
The ON/OFF lamp will come off, and the operation will stop.

3.2. Operation mode

Press the [F1] button to go through the operation modes in the order of “Cool, Dry, Fan, Auto, and Heat.”
Select the desired operation mode.

• Operation modes that are not available for the connected indoor unit will not appear on the display.
• Depending on the indoor unit model, either one or two set temperatures (single or dual set point(s)) can be set for Auto mode.

What the blinking mode icon means
The mode icon will blink when other indoor units in the same refrigerant system (connected to the same outdoor unit) are already operated in a different mode. In this case, the rest of the units in the same group can only be operated in the same mode.

Dry mode

• The indoor fan turns to the low-speed operation, disabling the change of fan speed.
• Dry operation cannot be carried out at room temperature of less than 18°C.
• The dry is a microcomputer-controlled dehumidifying operation which controls excessive air-cooling according to the room temperature of your choice. (Not usable for heating.)

1. Until reaching room temperature of your choice
   The compressor and indoor fan function is linked motion according to the change of the room temperature and automatically repeat ON/OFF.

2. When reaching room temperature of your choice Both the compressor and indoor fan stop.
   When stop continues for 10 minutes, the compressor and indoor fan are operated for 3 minutes to keep the humidity low.

Heat mode
“DEFROST” display
Displayed only during the defrosting operation.
“STAND BY” display
Displayed from the start of heating operation until the moment warm air blows out.

Caution:

• Never expose your body directly to cool air for a long time. Excessive exposure to cool air is bad for your health, and should therefore be avoided.

• When the air-conditioner is used together with burners, thoroughly ventilate the area. Insufficient ventilation can result in accidents due to oxygen deficiency.

• Never place a burner at a place where it is exposed to the airflow from the air-conditioner. Doing so can result in imperfect combustion of the burner.

• The microcomputer functions in the following cases:
  – Air does not blow out when heating starts.

• To prevent any cool air from escaping, the indoor fan is gradually switched in sequence from faint airflow/weak airflow/set airflow according to the temperature rise of the blown out air. Wait a moment until the airflow comes out naturally.
  – The fan is not moving at the set speed.

• In some models, the system switches over to faint airflow when the temperature of the room reaches the set temperature. In other cases, it stops to prevent any cool air from escaping during the defrosting operation.
  – Air flows out even if operation is stopped.

• Approximately 1 minute after the stop of operation, the indoor fan sometimes rotates to eliminate extra heat generated by the electric heater, etc. The fan speed comes to low or high.

Auto (dual set point) mode
When the operation mode is set to the Auto (dual set point) mode, two set temperatures (one each for cooling and heating) can be set. Depending on the room temperature, indoor unit will automatically operate in either the cooling or heating mode and keep the room temperature within the preset range.
The set temperatures that are specified for the Cool/Dry mode and the Heat mode will be used to automatically control the room temperature to stay within the set temperatures. This mode is especially effective during the in-between seasons, when the temperature difference between the highest and the lowest is large and both heating and cooling modes are used within the same day.

3.3. Set temperature

2. When the room temperature is higher than the set temperature during the heating mode
3. Immediately after the heating operation (during stand by for switching the operation mode)
4. During the Dry mode

The smart way to use

Even minimal steps to care for your air conditioner can help make its use far more effective in terms of air-conditioning effect, electricity charges, etc.
Set the right room temperature

• In cooling operation, a temperature difference of about 5°C between indoors and outdoors is optimum.
• If the room temperature is raised by 1°C during air-cooling operation, about 10% electric power can be saved.
• Excessive cooling is bad for health. It also results in the waste of electric power.

Clean the filter thoroughly

• If the screen of the air filter becomes clogged, the airflow and air-conditioning effect can be significantly reduced. Further, if the condition is left unattended, failure can result. It is particularly important to clean the filter at the beginning of the cooling and heating seasons. (When profuse dust and dirt have accumulated, clean the filter thoroughly.)

Prevent intrusion of heat during air-cooling

• To prevent the intrusion of heat during cooling operation, provide a curtain or a blind on the window to block out direct sunlight. Also, do not open the entrance or exit except in cases of dire necessity. Carry out ventilation sometimes
• Since the air periodically gets dirty in a room that is kept closed for a long time, ventilation is sometimes necessary. When gas appliances are used together with the air conditioner, special precautions must be taken. If the “LOSSNAY” ventilation unit developed by our company is used, you can perform ventilation with less waste. For details on this unit, consult with your dealer.

Caring for the machine

Always have filter maintenance performed by a service person. Before care- taking, turn the power supply OFF.
Caution:

• Wear protective gear when working on the unit.
  – Some components carry voltage for several minutes after the main power is turned off, posing electric shock hazards.

• Wear protective gear before touching any electrical components.
  – High-voltage parts pose a risk of electric shock, and high-temperature parts pose a risk of burns.

• Wear protective gloves when working on the unit.
  – Failure to do so may result in injury.

• To reduce the risk of injury from falling panels, ensure safety at the work space before installing, inspecting, or repairing the unit.

• Before you start cleaning, stop operation and turn OFF the power supply. Remember that the fan is rotating inside at high speed, posing a serious risk of injury.

• Indoor units are equipped with filters to remove the dust of sucked-in air.
  Clean the filters following the procedures below. (The standard filter should normally be cleaned once a week, and the long-life filter at the beginning of each season.)

• The life of the filter depends on where the unit is installed and how it is operated.

• After disinfecting the unit with chemicals, ventilate the room to disperse the chemical gas before operating the unit.
  – Exposure to splashes of chemicals may cause injury.
  – Chemicals entering the unit may corrode or deform the unit, causing malfunction.

5.1. Cleaning the indoor units and remote controllers

• Wipe with a dry soft cloth.

• Do not pull on or twist the remote controller cable.
  Do not remove the casing from the remote controller.

• To remove finger marks and oil, wipe with a cloth soaked in mild detergent, and wipe off the detergent.

• Do not use gasoline, benzene, thinner, polishing powder, or acid/alkaline solution to clean the indoor units and the controller, for they will damage the controller.

5.2. Cleaning the filter

• Clear dust away lightly or clean it up with a vacuum cleaner. In the case of severe staining, wash the filter in lukewarm water mixed with dissolved neutral detergent or water, and then rinse off the detergent completely. After washing, dry it and fix it back into place.
  Caution:

• Do not dry the filter by exposing it to direct sunlight or warming it using fire, etc. Doing so can result in the deformation of the filter.

• Washing it in hot water (more than 50°C) can also result in deformation.

• Never pour water or flammable sprays onto the air conditioner. Cleaning using these methods can result in the failure of the air conditioner, electric shock, or fire.

(To protect the compressor, a 3-minute restart- preventing circuit is built into the indoor unit. Therefore, there are occasions sometimes when the compressor does not start running immediately. There are cases when it does not run for as long as 3 minutes.)
Indoor unit operation was restarted during the heating and defrosting operation.| Wait for a while.
(Heating operation starts after ending defrosting operation.)
It runs briefly, but soon stops.| The “CHECK” and check code flash on the liquid crystal display.| There are some obstacles at the air inlet and outlet of the indoor and outdoor units.| Rerun after removal
The filter is filled with dust and dirt.| Rerun after cleaning the filter. (Refer to section 5 “Caring for the machine”.)
The sound of the exhaust and rotation of the motor can still be heard after stop of running.| All lights are out except the ruled line and clock.| When other indoor units are engaged in cooling operation, the machine stops after running a drain-up mechanism for 3 minutes when air-cooling operation is stopped.| Wait for 3 minutes.
The sound of the exhaust and the rotation of the motor can be heard intermittently after stop of running.| All lights are out except the ruled line and clock.| When other indoor units are engaged in cooling operation, drained water is brought in. If the drain water is collected, the drain-up mechanism initiates a draining operation.| It soon stops. (If the noise occurs more than 2-3 times in an hour, ask for repair service.)
Warm air comes out intermittently when the thermostat is OFF or during fan operation.| The liquid crystal display shows that it is in the state of operation.| When other indoor units are engaged in heating operation, the control valves are opened and closed from time to time to maintain the stability of the system.| It soon stops. (If the room temperature rises uncomfortably high in a small room, stop operation.)

• If operation stops due to a power failure, the [restart-preventing circuit at power failure] operates and disables unit operation even after power restoration. In this case, press the [ON/OFF] button again and start operation.
  If malfunctions persist after you have checked the above, turn the power supply OFF and contact your dealer with information about the product name, the nature of the malfunction, etc. If the display of error information flashes, tell the dealer contents of the display (error code). Never attempt to repair by yourself.

The following symptoms are not air conditioner failures:

• The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of cosmetics, the walls, furniture, etc., absorbed in the air conditioner.
• A hissing noise can be heard immediately after the air conditioner is started or stopped. This is the sound of the refrigeration flowing inside the air conditioner. This is normal.
• The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and other sections due to expansion and contraction caused by temperature change. This is normal.
• The fan speed changes in spite of not changing the setting. Not to blow out cold air at the beginning of heating operation, the air conditioner automatically adjusts the fan speed gradually from lower to the set speed. It also adjust its fan speed to protect the fan motor when return air temperature or fan speed excessively rises.

Installation, transferring works, and checking

Regarding place for installation
Consult with your dealer for details on installation and transferring the installation.
Caution:

• Never install the air conditioner where there is a risk of leakage of flammable gas. If gas leaks and accumulates around the unit, fire can result.

• Never install the air conditioner at the following place:
  – where there is a lot of machine oil
  – near the ocean and beach areas where there is salt air.
  – where humidity is high
  – where there are hot springs nearby
  – where there is sulphurous gas
  – where there is a high-frequency processing machinery (a high-frequency welder, etc.)
  – where acid solution is frequently used
  – where special sprays are frequently used.

• Install the indoor unit horizontally. Otherwise, water leakage can result.

• Take sufficient measures against noise when installing the air conditioners at hospitals or communication-related businesses.

If the air conditioner is used in any of the above-mentioned environments, frequent operational failure can be expected. It is advisable to avoid these types of installation sites.
