fi

 ciently.

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 danger, warning, and caution notices given in this manual.

WARNING:

  This symbol refers to a hazard or unsafe practice which can result in 
severe personal injury or death.

CAUTION:

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

If Necessary, Get Help

These instructions are all you need for most installation sites and maintenance condi-
tions. If you require help for a special problem, contact our sales/service outlet or your 
certi

fi

 ed dealer for additional instructions.

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 recon-

nected 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 inad-
equate 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 

fi

 re 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 

fi

 ns on the air conditioner can cut your 

fi

 ngers.

When Installing...
...In a Ceiling or Wall

Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be neces-
sary 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 

fl

 oors.

...In an Area with High Winds

Securely anchor the outdoor unit down with bolts and a metal frame. 
Provide a suitable air baf

fl

 e.

...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 

fl

 are method for connecting tubing.

• Apply refrigerant lubricant to the matching surfaces of the 

fl

 are 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.

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 

fi

 ngers and clothing away from any moving parts.

•  Clean up the site after you 

fi

 nish, 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.

 DANGER

Never touch electrical components immediately after the power supply has been 
turned off. Electrical shock may occur. After turning off the power, always wait 5 
minutes or more before touching electrical components.

•  Be sure to read this Manual thoroughly before installation.
•  

The warnings and precautions indicated in this Manual contain important information 
pertaining to your safety. Be sure to observe them.

•  

Hand this Manual, together with the Operating Manual, to the customer. Request the 
customer to keep them on hand for future use, such as for relocating or repairing the 
unit.
