1. SAFETY PRECAUTIONS

1.1. IMPORTANT! Please read before starting

This air conditioning system meets strict safety and operating standards.

As the installer or service person, it is an important part of your job to install or service the

system so it operates safely and efficiently.

For safe installation and trouble-free operation, you must:

• Carefully read this instruction booklet before beginning.

• Follow each installation or repair step exactly as shown.

• Observe all local, state, and national electrical codes.

• Pay close attention to all warning and caution notices given in this manual.

This symbol refers to a hazard or unsafe practice which can result in

WARNING:

severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result in

CAUTION:

personal injury and the potential for product or property damage.

• Hazard alerting symbols

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance conditions.

If you require help for a special problem, contact our sales/service outlet or your certified

dealer for additional instructions.

In Case of Improper Installation

The manufacturer shall in no way be responsible for improper installation or maintenance

service, including failure to follow the instructions in this document.

1.2. Special precautions

When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A

QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

• Do not supply power to the unit until all wiring and tubing are completed or reconnected

and checked.

• Highly dangerous electrical voltages are used in this system. Carefully refer to the wir-

ing diagram and these instructions when wiring. Improper connections and inadequate

earthing (grounding) can cause accidental injury or death.

• Earth (Ground) the unit following local electrical codes.

• Connect all wiring tightly. Loose wiring may cause overheating at connection points and

a possible fire hazard.

When Transporting

Be careful when picking up and moving the indoor and outdoor units. Get a partner to

help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin

aluminum fins on the air conditioner can cut your fingers.

When Installing...

...In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit's weight. It may be necessary

to construct a strong wood or metal frame to provide added support

...In a Room

Properly insulate any tubing run inside a room to prevent "sweating" that can cause drip-

ping and water damage to walls and floors.

...In Moist or Uneven Locations

Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the

outdoor unit. This prevents water damage and abnormal vibration.

...In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable air baffle.

...In a Snowy Area (for Heat Pump-type Systems)

Install the outdoor unit on a raised platform that is higher than drifting snow.

When Connecting Refrigerant Tubing

• Keep all tubing runs as short as possible.

• Use the flare method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before

connecting them, then tighten the nut with a torque wrench for a leak-free connection.

• Check carefully for leaks before opening the refrigerant valves.

NOTE:

Depending on the system type, liquid and gas lines may be either narrow or wide.

Therefore, to avoid confusion the refrigerant tubing for your particular model is specified

as either "small" or "large" rather than as "liquid" or "gas".

When Servicing

• Turn the power OFF at the main circuit breaker panel before opening the unit to check

or repair electrical parts and wiring.

• Keep your fingers and clothing away from any moving parts.

• Clean up the site after you finish, remembering to check that no metal scraps or bits of

wiring have been left inside the unit being serviced.

• After installation, explain correct operation to the customer, using the operating manual.

Indicates a potentially or imminently hazardous situation which, if

WARNING

not avoided, could result in death or serious injury.

To avoid getting an electric shock, never touch the electrical components soon after the

power supply has been turned off. After turning off the power, always wait 10 minutes or

more before you touch the electrical components.

Installation of this product must be done by experienced service technicians or

professional installers only in accordance with this manual. Installation by non-

professional or improper installation of the product may cause serious accidents such

as injury, water leakage, electric shock, or fire.

If the outdoor unit is installed in disregard of the instructions in the installation manual, it

will void the manufacturer's warranty.

Do not turn on the power until all work has been completed. Turning on the power

before the work is completed can cause serious accidents such as electric shock or fire.

If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant is

exposed to a direct flame, it may produce a toxic gas.

Installation work must be performed in accordance with regulations, codes, or standards

for electrical wiring and equipment in each country, region, or the installing place.

Do not use this equipment with air or any other unspecified refrigerant in the refrigerant

lines. Excess pressure can cause a rupture.

During installation, make sure that the refrigerant pipe is attached firmly before you run

the compressor. Do not operate the compressor under the condition of refrigerant piping

not attached properly with 3-way valve open. This may cause abnormal pressure in the

refrigeration cycle that leads to rupture and even injury.
