Safety Precautions

• Read these Safety Precautions carefully to ensure correct installation.

• This manual classifies the precautions into WARNING and CAUTION.

Be sure to follow all the precautions below: they are all important for ensuring safety.

WARNING...............Failure to follow any of WARNING is likely to result in such grave consequences as death or serious injury.

CAUTION...............Failure to follow any of CAUTION may result in grave consequences in some cases.

• The following safety symbols are used throughout this manual:

• After completing installation, test the unit to check for installation errors. Give the user adequate instructions concerning the use 

and cleaning of the unit according to the Operation Manual.

 Be sure to observe this instruction.

 Be sure to establish an earth connection.

 Never attempt.

WARNING

• Installation should be left to the dealer or another professional.

Improper installation may cause water leakage, electrical shock, or fire.

• Install the air conditioner according to the instructions given in this manual.

Incomplete installation may cause water leakage, electrical shock, or fire.

• Be sure to use the supplied or specified installation parts.

Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.

• Install the air conditioner on a solid base that can support the weight of the unit.

An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.

• Electrical work should be carried out in accordance with the installation manual and the national electrical wiring

rules or code of practice. 

 Insufficient capacity or incomplete electrical work may cause electrical shock or fire.

• Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
• For wiring, use a cable length enough to cover the entire distance with no connection. 

Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.

(Failure to do so may cause abnormal heat, electric shock or fire.)

• Use the specified types of wires for electrical connections between the indoor and outdoor units.

Firmly clamp the interconnecting wires so their terminals receive no external stresses.  Incomplete connections or clamping may cause termi-
nal overheating or fire.

• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force 

on the electrical covers or panels.

Install covers over the wires.  Incomplete cover installation may cause terminal overheating, electrical shock, or fire.

• If any refrigerant has leaked out during the installation work, ventilate the room.

(The refrigerant produces a toxic gas if exposed to flames.)

• After all installation is complete, check to make sure that no refrigerant is leaking out.

(The refrigerant produces a toxic gas if exposed to flames.)

• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the 

specified  refrigerant (R410A), such as air.

(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)

• During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, 
causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

• During installation, attach the refrigerant piping securely before running the compressor.

If the compressor is not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing 
abnormal pressure in the freezer cycle which will lead to breakage and even injury.

• Be sure to establish an earth.  Do not earth the unit to a utility pipe, arrester, or telephone earth.

Incomplete earth may cause electrical shock, or fire.    A high surge current from lightning or other sources may cause damage to the air conditioner.

• Be sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in electric shocks, or fire.

CAUTION

• Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage. 

If the gas leaks and builds up around the unit, it may catch fire.

• Establish drain piping according to the instructions of this manual.

Inadequate piping may cause flooding.

• Tighten the flare nut according to the specified method such as with a torque wrench.

If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant leakage.

Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.

Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.
