IMPORTANT

These air conditioners employ new refrigerant R410A.

Pay special attention when servicing the unit.

REFERENCE NO. SM700876

SAFETY PRECAUTIONS

•Before doing repair work, please read the "SAFETY PRECAUTIONS" carefully and fully understand them.

•The precautionary items here are divided into "Warning" and "Caution" items.

Items in particular which may cause death or serious injury to the service personnel if the work is not performed correctly,

are included in the "Warning" table.

However, even precautionary items identified as "Caution" also have the potential for serious consequences if not performed correctly.

Important safety precautions are described for all items in both categories. Be sure to carefully follow all of them.

•Symbol Indication

: This symbol indicates items to which we need to pay attention. In this triangle, a definite precautionary item is described.

: This symbol indicates the item to be prohibited.

In or close to this circle, a prohibited item is described.

: This symbol indicates the items requiring special attention or instruction. In or close to this circle, a prohibited item is described.

•After doing repair work, perform a test run to confirm that there are no abnormalities. At the same time, explain the precautions in use to the user.

Warning

Before performing an overhaul, disconnect the power plug or power cable from the unit.

Performing the work with the power supplied to the unit, may cause an electric shock.

When repair work or circuit inspection that requires power supply for the air conditioner, is to be performed,
do not touch the charging section.
Doing so may cause an electric shock.	Prohibit

For the step-up capacitor attached to the electric section, perform the repair work after sufficiently discharging it. Insufficient capacitor discharge may cause an electric shock.

Do not perform repair work on the electric sections with wet hands.

Doing so may cause an electric shock.

Prohibit

Do not start or stop the air conditioner by means of connecting or disconnecting the power plug.

Doing so may cause an electric shock or fire.

Prohibit

When conducting repair work only use components included in the parts list for the corresponding unit and perform the work with the appropriate tools.

Incorrect or poor repair work may cause an electric shock or fire.

Never modify the unit.

Doing so may cause an electric shock or fire.

Prohibit

Perform all electric work according to local applicable regulations related to electrical equipment or interior wiring regulation and make sure to use the exclusive circuit.

Insufficient capacity to the electric circuit or defective arrangement results may cause an electric shock or fire.

Make sure to replace any power cable or lead wire showing any signs of scratch or deterioration.

Failure to do so may cause an electric shock, overheating or fire.

Make sure that there is no dust on or slack in the power plug and insert fully into the socket.

Dust or incomplete connections may cause an electric shock or fire.

Do not damage or process the power cord, as it may cause an electric shock or fire.

Prohibit

For the wiring between the indoor unit and outdoor unit, securely fix the specified cable onto the terminal plate. Poorly fixed wiring may cause a heat or fire.

After connecting the wiring between the indoor unit and outdoor unit, attach the terminal cover securely. Incomplete attachment of the terminal cover may cause overheating or fire.

Warning

If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite.

Prohibit

If refrigerant gas leaks during the work, ventilate the room.

If refrigerant gas catches fire, harmful gas may be generated.

Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.
If air or other contaminants mix with the gas, pressure will become extremely high in the refrigerating cycle,
which may cause a unit breakdown."	Prohibit

When the welded section of the compressor intake or discharge pipe is to be disconnected, perform it in a well-ventilated place after sufficiently recovering the refrigerant gas.

Any residue gas may jet out refrigerant or refrigerating machine oil, which may cause an injury.

When the work is to be performed in a high place (About 2 meters or more), make sure to wear a safety helmet, gloves and safety belt. Insufficient safety gear may cause a serious injury in case of a fall.

When the unit is to be relocated, confirm that the new installation location has sufficient strength for the weight of the unit. Insufficient strength of the installation location and incomplete installation work may cause an injury due to

the unit falling.

When the remote controller batteries are replaced, dispose of the old batteries out of the reach of children. If a child swallows a battery, make sure that the child gets immediate medical attention.

Caution

Do not wash the air conditioner with water, as this may cause an electric shock or fire.

Prohibit

For the repair work in places with high humidity or moisture, make sure to ground the unit.

Failure to do so may cause an electric shock.

Confirm that the component attachment position, wiring condition, soldering condition and connector connection are normal.

If not, it may cause overheating or fire.

Confirm that the temperature around the compressor is not too high, and then perform the repair work. Failure to do so may cause a burn.

Perform welding work in a place with good ventilation.

If the work is performed in a poorly ventilated area, it might cause a lack of oxygen.

If the installation plate or attachment frame has deteriorated due to corrosion, etc., replace it.

Failure to do so may cause an injury due to the unit falling.

When the cleaning is to be performed, make sure to turn off the power and pull out the plug.

Touching the fan that is rotating at high speed may result in an injury.

When the indoor unit is to be removed, do not place it on an incline.

Doing so may cause wet furniture because water left inside may trickle down.

Prohibit

Do not hold the sharp end of the unit or the aluminum fins, as it may cause an injury to your hand or finger.

Prohibit

After repairs, make sure to measure the insulation resistance and confirm that the value is 1 Mohm or more. Any insulation error may cause an electric shock.

After repairs, make sure to check the drainage of the indoor unit.

Inappropriate drainage may cause wet furniture and floors due to water leakage.
