The failure code of every unit will display for 3 seconds. After the failure codes of all indoor units in the whole group are displayed, the mode will quit automatically.

Heating Mode

"HOT KEEP" function

"HOT KEEP"is operated in the following cases.

When heating is started: In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating mode. Defrosting operation (in the heating mode): When it is liable to frost, the heating operation is stopped automatically for 5 to 12 minutes once per approx. one hour, and defrosting is operated. After defrosting is completed, operation mode is automatically changed to ordinary heating operation. When the room thermostat is actuated: When room temperature increases and room temperature controller actuates, the fan speed is automatically changed to stop under low temperature condition of indoor heat exchanger. When room temperature decreases, air conditioner automatically changes over to ordinary heating operation.

Warming Operation

Heat pump type warming With the heat pump type warming, the mechanism of heat pump that concentrate heat of outdoor air with the help of refrigerant to warm the indoor space, is utilized. Defrosting operation When a room is warmed with a heat pump type air conditioner, frost accumulates on the heat exchanger of outdoor unit along with the drop of indoor temperature. Since the accumulated frost reduces the effect of warming, it is necessery to automatically switch the operation to the defrosting mode. During the defrosting operation, heating operation is interrupted. Atmospheric temperature and warming capacity Warming capacity of heat pump type air conditioner decreases along with the drop of outdoor temperature. When the warming capacity is not sufficient, it is recommended to use another heating implement. Period of warm-up Since the heat pump type air conditioner employs a method to circulate warm winds to warm the entire space of a room, it takes time before the room temperature rises. It is recommendable to start the operation a little earlier in a very cold morning.

Care and Maintenance

Points to observe

Turn off the power supply switch. Do not touch with wet hand. Do not use hot water or volatile liquid.

Do not use!

There is a irregularity in operation or abnormal sound is audible.

When the CHECK LED1 (red) flickers, an irregularity has occurred in the air conditioner.

Troubleshooting

The followings are not malfunction

Water flowing sound is heard.

Shuru

When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a trouble.

This is caused by heat expansion or contraction of plastics.Cracking sound is heard.

It smells. Air which blows out from the indoor unit sometimes smells. The smell results from

residents of tobacco smoke or cosmetics stuck inside of unit.

During operation, white fog comes out of indoor unit.

When the air conditioner is used at restaurant etc. where dense edible oil fume is always exists, white fog sometimes blows out of air outlet during operation. In this case consult sales dealer for cleaning the heat exchanger.

It is switched into the FAN mode during cooling.

To prevent frost from being accumulated on the indoor unit heat exchanger, it is sometimes automatically switched to the FAN mode but it will soon return to the cooling mode.

The air conditioner can not be restarted soon after it stops.

Unit does not start

Air does not blow or the fan speed can not be changed during

Even if the operation switch is turned on, cooling, dehumidifying or heating is not operable for three minutes after the conditioner is stopped. Because the protecting circuit is activated (During this time air conditioner operates in fan mode).

Precaution For Installation

Please read these "Safety Precautions" first then accurately execute the installation work. Though the precautionary points indicated herein are divided under two headings, and , those points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in the section. However, there is also a possibility of serious consequences in relationship to the points listed in the section as well. In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned. After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner's manual. Moreover, ask the customer to keep this sheet together with the owner's manual.

This system should be applied to places as office, restaurant, residence and the like. Application to inferior environment such as engineering shop could cause equipment malfunction. Please entrust installation to either the company which sold you the equipment or to a professional contractor. Defects from improper installations can be the cause of water leakage, electric shocks and fires. Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires. When a large air-conditioning system is installed to a small room, it is necessary to have a prior planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration. In regards to preparing this countermeasure, consult with the company from which you perchased the equipment, and make the installation accordingly. In the rare event that a refrigerant leakage and exceeding of threshold concentration does occur, there is the danger of a resultant oxygen deficiency accident. For installation, confirm that the installation site can sufficiently support heavy weight. When strength is insufficient, injury can result from a falling of the unit. Execute the prescribed installation construction to prepare for earthquakes and the strong winds of typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling over of the unit. For electrical work, please see that a licensed electrician executes the work while following the safety standards related to electrical equipment, and local regulations as well as the installation instructions, and that only exclusive use circuits are used. Insufficient power source circuit capacity and defective installation execution can be the cause of electric shocks and fires. Accurately connect wiring using the proper cable, and insure that the external force of the cable is not conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire. Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper installation can also result in heat generation or fire. When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R410A) within the refrigeration cycle. Rupture and injury caused by abnormal high pressure can result from such mixing. Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refrigerant leakage.

WARNING

CAUTION

WARNING

CAUTION

Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire. Improper placement of ground wires can result in electric shock. The installation of an earth leakage breaker is necessary depending on the established location of the unit. Not installing an earth leakage breaker may result in electric shock. Do not install the unit where there is a concern about leakage of combustible gas. The rare event of leaked gas collecting around the unit could result in an outbreak of fire. For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.
