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 troublefree 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 WARNING unsafe practice which can result in severe personal injury or death. CAUTION SPECIAL PRECAUTIONS WARNING When Wiring 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. 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. 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 wiring diagram and these instructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death. Ground the unit following local electrical codes. Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard. Install a protective leakage breaker depending on the installation location (especially a damp or humid location). If a leakage breaker is not installed, electric shock can occur. 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 dripping 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 Pumptype Systems) Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents. When Connecting Refrigerant Tubing 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 leakfree connection. Check carefully for leaks before starting the test run. 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 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. 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.

7. MAINTENANCE 7. Address Setting of the Remote Control Unit The address can be set in order to prevent interference between remote controllers when two indoor units are installed near each other. The address is normally set to "A." To set a different address, it is necessary to change the address on the second remote controller. Tab Fig. 3 NOTE Once changed, you cannot restore the original address setting of the air conditioner. () Switch on the power source. () Break the addresssetting tab marked "A" on the second remote controller to change the address (Fig. 3). When the tab is removed, the address is automatically set to B (Fig. 4). (3) Press and hold the remote controller HIGH POWER button and HR TIMER button. Then, press and hold the ACL (reset) button with a pointed object such as the tip of a pen. After 5 seconds, release ACL button first, then release HIGH POWER and HR. TIMER buttons, "op" (test run) appears, blinking in the remote controller clock display area. (4) Each time the HR TIMER button is pressed, the display changes as shown below. Press this button times to change the display to "op7" (address setting). (Fig. 5) Test run mode Selfdiagnostic mode Address setting mode (5) "op7" has now been selected for address setting. (6) Press the ON/OFF operation button on the remote controller. (Fig. 5) Check that the "beep" signal received sound is heard from the second indoor unit (approximately 5 times). The sound you hear is the signal that the remote controller address has been changed. (7) Finally press the remote controller ACL (reset) button to cancel the blinking "op7" display. (Fig. 5) Changing of the second remote controller address is now completed. 37 HIGH POWER button Fig. 4 Fig. 5 ON/OFF operation button HR. TIMER button ACL (Reset) button ACL button
7. Disconnecting and Connecting Positive Connector for Outdoor Unit One of the two types of connectors illustrated at left is used. Their basic structure is the same for each. How to Disconnect Pull the cover upward Hold the resin connector cover, and pull the connector off. You cannot disconnect the connector by pulling the wire since it is locked inside. Always hold the cover to disconnect. (See illustration at left.) For the connector without the resin cover, push the lock in the direction of "" while pulling it off. How to Connect In order to connect, hold the resin cover of the connector and push it in. Confirm the click sound for the inside lock. When the cover is pulled upward, the lock is released with the sequence of and. 38
73. Disassembly Procedure WARNING To avoid electrical shock hazard, be sure to disconnect power before attempting to disassemble the unit. When a footstool, etc. is used for disassembling the indoor unit, be careful not to fall down. If you fall down, you might be injured seriously. 73. Remove the air intake grill. () Slide the latches each to the corresponding arrow direction. (Fig. and Fig. ) Open downward the air intake grill located on the latch side. () Undo the air intake grill drop preventive hook.
