•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.
DANGER
•Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion, especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
•If the refrigerant gas leaks during installation, ventilate the area immediately.
Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. Exposure to this gas could cause severe injury or death.
• After completing the installation work, check that the refrigerant gas does not leak.
Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove or cooking device. Exposure to this gas could cause severe injury or death.
•Do not ground units to water pipes, telephone wires or lightning rods because incomplete grounding could cause a severe shock hazard resulting in severe injury or death, and to gas pipes because a gas leak could result in an explosion which could lead to severe injury or death.
•Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children will not play with them.
Children playing with plastic bags face the danger of death by suffocation.
•Do not install unit in an area where flammable materials are present due to risk of explosion resulting in serious injury or death.
•Do not ground units to telephone wires or lightning rods because lightning strikes could cause a severe shock hazard resulting in severe injury or death, and to gas pipes because a gas leak could result in an explosion which could lead to severe injury or death.
WARNING
• Installation shall be left to the authorized dealer or another trained professional.
Improper installation may cause water leakage, electrical shock, fire, or equipment damage.
• Install the air conditioner according to the instructions given in this manual.
Incomplete installation may cause water leakage, electrical shock, fire or equipment damage.
• Be sure to use the supplied or exact specified installation parts.
Use of other parts may cause the unit to come to fall, water leakage, electrical shock, fire or equipment damage.
• Install the air conditioner on a solid base that is level and can support the weight of the unit.
An inadequate base or incomplete installation may cause injury or equipment damage in the event the unit falls off the base or comes loose.
• Electrical work shall be carried out in accordance with the installation manual and the national, state and local electrical wiring codes.
Insufficient capacity or incomplete electrical work may cause electrical shock, fire or equipment damage.
•Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. Follow all appropriate electrical codes.
•For wiring, use a wire or cable long enough to cover the entire distance with no splices if possible. Do not use an extension cord. Do not put other loads on the power supply.
Use an only a separate dedicated power circuit.
(Failure to do so may cause abnormal heat, electric shock, fire or equipment damage.)
• Use the specified types of wires for electrical connections between the indoor and outdoor units. Follow all state and local electrical codes.
Firmly clamp the inter-unit wire so their terminals receive no external stresses.
Incomplete connections or clamping may cause terminal overheating, fire or equipment damage.

Safety Precautions
WARNING
• After connecting all wires be sure to shape the cables so that they do not put undue stress on the electrical covers, panels or terminals.
Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, fire or equipment damage.
• When installing or relocating the system, be sure to keep the refrigerant circuit free from all 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 which may result in 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 abnormally high pressure which could lead to equipment damage or and personal injury.
• During installation, attach the refrigerant piping securely before running the compressor.
If the refrigerant pipes are not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing abnormally high pressure which could lead to equipment damage and personal injury.
• Be sure to install a ground fault circuit interrupter breaker.
Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, or fire personal injury.
CAUTION
• Do not install the air conditioner where gas leakage would be exposed to open flames.
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 water damage.
• Tighten the flare nut according to the specified torque. A torque wrench should be used.
If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.
• Do not touch the heat exchanger fins.
Improper handling may result in injury.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.
• 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.
•The temperature of refrigerant circuit will be high, please keep the inter-unit wire away from copper pipes that are not thermally insulated.
•Electrical work must be performed in accordance with the NEC/CEC by authorized personnel only.

1)Choose a place solid enough to bear the weight and vibration of the unit, where the operation sounds will not be amplified.
2)Choose a location where the hot air discharged from the unit or the operation sounds will not disturb the neighbors of the user.
3)Avoid installing near bedrooms so that operation sounds will not be a problem.
4)There must be sufficient spaces 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.
7)Install units, power cords and inter-unit wire at least 10ft (3m) 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 (3m) 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 anything under the unit which must be kept away from moisture.
NOTE
Cannot be installed hanging from ceiling or stacked.
CAUTION
When operating the air conditioner in a low outdoor ambient temperature, be sure to follow the instructions described below.
•To prevent exposure to wind, install the outdoor unit with its suction side facing the wall.
•Never install the outdoor unit at a site where the suction side may be exposed directly to wind.
•To prevent exposure to wind, it is recommended to install a baffle plate on the air discharge side of the outdoor unit.
•In heavy snowfall areas, select an installation site where the snow will not affect the unit.
Construct a large canopy. Construct a pedestal.
Install the unit high enough off the ground to prevent burying in snow.
•Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installed.
•In accordance with the foundation drawing, fix the unit securely by means of the foundation bolts.
(Prepare 4 sets of 1/2 inch (M12) foundation bolts, nuts and washers each which are available on the market.)
•It is best to screw in the foundation bolts until their ends are 3/4 inch (20mm) from the foundation surface.
