WARNING
CAUTION
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 bellow: they are all important for ensuring safety.
Failure to follow any of WARING is likely to result in such grave consequences as death or serious injury.
Failure to follow any of CAUTION may in some cases result in grave consequences.
The following safety symbols are used throughout this manual:
Be sure to observe this instruction Be sure to establish an earth connection Never attempt
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.
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 suplied or specified installation parts.
Use of other parts may cause the unit to come lose, water leakage, electrical shock, or fire.
Install the air conditioner on a solid base that can support the unit's weight.
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 long 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 terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.
After connectiong 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 while the compressor is running, causing abnormal pressure and no
condense-able added to the system.
Be sure to establish a ground. Do not ground the unit to a utility pipe, arrester, or telephone earth.
In complete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.
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.

Accessories supplied with the outdoor unit:
1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.
2) Choose a location where the hot air discharged from the unit or the operation noise, will not cause a nuisance to the neighbors of the
user.
3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.
4) There must be sufficient space for carrying the unit into and out of the site.
5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.
6) The site must be free from the possibility of flammable gas leakage in a nearby place.
Locate the unit so that the noise and the discharged hot air will not annoy the neighbors.
7) Install units, power cords and inter-unit cables at least 10ft away from television and radio sets. This is to prevent interference to images
and sounds. (Noises may be heard even if they are more than 10ft away depending on radio wave conditions.)
8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air conditioner.
9)Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away from moisture.
Cannot be installed hanging from ceiling or stacked.

If there is the danger of the unit falling or overturning, fix the unit with foundation bolts, or with wire or other means.
If the location does not have good drainage, place the unit on a level mounting base(or a plastic pedestal).
Install the outdoor unit in a level position. Failure to do so may result in water leakage or accumulation.
