IMPORTANT!

Please Read Before Starting

This air conditioner 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 the INSTRUCTION MANUAL and INSTALLATION INSTRUCTIONS attached to each air conditioner 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 severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.

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.

SPECIAL PRECAUTIONS

WARNING	When Wiring

ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE THIS SYSTEM.

•All wiring must conform to local electrical codes.

•Each unit must be properly grounded with a ground (or earth) wire or through the supply wiring.

•DO NOT, under any circumstances, cut or remove the third (ground) prong from the power cord plug.

•DO NOT use an adapter Plug or extension cord.

•DO NOT use a damaged power cord, plug, or wall outlet. Replace them immediately.

•DO NOT change the internal wiring or any part of the system.

•DO NOT turn the air conditioner on and off by plugging and unplugging. Use the Operation switch.

When Transporting

Be careful when picking up and moving the air conditioner. 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

Place of Installation

•If possible, install the unit in a shady location.

•Install it at a spot where optimum air circulation can be obtained. No chairs or other obstructions are allowed in front of the air conditioner.

•Keep enough space from any outside obstruction (wall, bush, etc.).

Dimension of

Room side		157	/8"	16	7/8"	Outside

Minimum 5" from the floor

Box and receptacle

•As a safety measure, it is recommended that two people install the unit.

•Hold the unit securely, and be careful not to drop any parts if the air conditioner is being installed on an upper floor of a multistory building.

When Servicing

•Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts and wiring.

•Keep 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 tools have been left inside the unit being serviced.

Others

CAUTION

•Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.

•Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.
