Do not use any refrigerant different from the one speci ed for complement or replacement. Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or an injury to your body.

Places where the operation sound of the outdoor unit may cause a disturbance. (Especially at the boundary line with a neighbor, install the air conditioner while considering the noise.)

This appliance is intended to be used by expert or trained users in shops, in light industry, or for commercial use by lay persons.

Transportation and storage When transporting the air conditioner, wear shoes with protective toe caps, protective gloves, and other protective clothing.

When transporting the air conditioner, do not take hold of the bands around the packing carton. You may injure yourself if the bands should break.

When stacking the packing cartons for storage or transportation, heed the precautions written on the packing cartons. Failure to heed the precautions may cause the stack to collapse.

You shall ensure that the air conditioner is transported in stable condition. If you nd any part of the product broken, contact your dealer.

Installation Only a quali ed installer (*1) or quali ed service person (*1) is allowed to carry out the electrical work of the air conditioner. Under no circumstances must this work be done by an unquali ed individual since failure to carry out the work properly may result in electric shocks and/or electrical leaks.

After the installation work has been completed, have the installer explain about the circuit breaker positions. In the event that error has occurred in the air conditioner, set the circuit breaker to the OFF position, and contact a service person.

If you install the 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 highly concentrated refrigerant may cause an oxygen de ciency accident.

Do not install the air conditioner in a location that may be subject to a risk of expire to a combustible gas. If a combustible gas leaks and becomes concentrated around the unit, a re may occur.

Be sure to use the company-speci ed products for the separately purchased parts. Use of non-speci ed products may result in re, electric shock, water leakage, etc. Have the installation performed by a professional.

6 Installation Location

Avoid locations where inside the ceiling is used as a route for fresh air. Install the fresh air intake unit considering a discharge port position. The fresh air intake unit has a different

discharge temperature compared with the indoor unit for air conditioner. Avoid installing near machines emitting high frequency waves. Not suitable for chemical plants such as lique ed carbon dioxide refrigerant plants. Do not install the air conditioner in locations where iron or other metal dust is present. If iron or other metal dust

adheres to or collects on the interior of the air conditioner, it may spontaneously combust and start a re. A failure may occur in certain locations such as the following:

Areas with large amount of oil droplets (including machine oil) or vapors Salty areas near oceans, etc. Hot springs emitting sul dizing gas, etc. Heavily acidic or alkaline places. Special maintenance or parts are required for use in the above places. For details, contact the dealer where you purchased the product.

Leave an enough space around the air intake and discharge of the outdoor unit so that the ventilation is not restricted.

Avoid places where strong wind may blow against the air intake and discharge of the outdoor unit. Attach a snow stand, snow hood, etc. to the outdoor unit for use in snowfall areas. For details, contact the dealer

where you purchased the product. Make sure drain water from the outdoor unit is emitted into places with good drainage. Make sure the long life pre lter and high-ef ciency lter are installed in the lter chamber. If the long life pre lter

and high-ef ciency lter are not attached, heat exchangers etc. clogged with dust can result in water leakage. Attach the long life per lter and high-ef ciency lter because dust can also get into the area being air conditioned.

Keep a distance of at least 1 m between the air conditioner / remote controller and a TV or radio. Failure to observe this precaution may cause visual disturbance or noise.

Leave a distance of at least 1.5 m between the air discharge and a re alarm. If this precaution is not observed, the alarm may not work properly or detect re in case of re.

Be careful of operation sounds Locate the unit in a place secure enough so that the sounds and vibrations do not increase. If something is placed near the air discharge of the outdoor unit, noise may increase. Be careful not to disturb your neighbors with cool / warm air or noise coming from the air discharge of the outdoor

unit.

During cooling When the air intake or air discharge of the outdoor

unit is blocked. When strong wind blows continuously against the air

discharge of the outdoor unit.

During heating (for heat-pump model only) When dust or dirt is excessively adhered to the air lter of the indoor unit.

When the air discharge of the indoor unit is blocked.

NOTE When the protective device activates, turn off the power switch, remove the cause, and then restart running.

Cooling / Heating operations Each unit can be controlled individually. However, indoor units connected to the same outdoor unit cannot perform cooling and heating simultaneously. When you attempt simultaneous operation, indoor units performing cooling are stopped, and the running preparation indicator is displayed on the remote controller. An indoor unit performing heating continues running. When you attempt an operation without the con gured settings, the running preparation indicator is displayed on the remote controller and operation stops. If operation is xed to cooling or heating by the air conditioner administrator, only the con gured settings apply to the operation.

Characteristics of heating When the outside temperature increases, the outdoor unit may stop.

8 Maintenance WARNING

For daily maintenance including Air Filter cleaning, make sure to ask the quali ed service person particularly following models as the maintenance requires high-place work;

CAUTION

Do not push buttons with wet hands. Doing so may result in electric shock.

Cleaning the air lters Ask quali ed service person to clean the lters for the models listed in the warning on the top of this chapter. Clogged lters may lower the cooling and heating performance.

Long life pre lter Remove dust with a vacuum cleaner or rinse it off with water. If excessively dirty, it can be cleaned effectively by

washing it with a soft brush and neutral detergent. After washing with water, drain off the water and dry

it in the shade.

REQUIREMENT Do not wash with water that is over 50C.

This may cause discoloration or deformation. Do not expose to re. Doing so could cause a re.

High-ef ciency lter Replace it when it is time for replacement. When cleaning the long life pre lter, check the dust collecting status and the reduction in air volume for the high-ef ciency lter, then replace the pre lter when it is time for replacement (approximately 2500 hours of operation is recommended). Note that the high-ef ciency lter cannot be washed with water and reused. However, the lifetime of the high-ef ciency lter may be shortened depending on the intake air condition.
