When Transporting  
IMPORTANT!  
Please Read Before Starting  
Be careful when picking up and moving the indoor and out-  
door 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.  
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.  
When Installing…  
…In a Ceiling or Wall  
For safe installation and trouble-free operation, you must:  
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.  
G
Carefully read this instruction booklet before beginning  
G
Follow each installation or repair step exactly as shown  
G
Observe all local, state, and national electrical codes  
…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.  
G
Pay close attention to all warning and caution notices  
given in this manual  
This symbol refers to a hazard or  
…In Moist or Uneven Locations  
unsafe practice which can result  
in severe personal injury or  
death.  
WARNING:  
CAUTION:  
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.  
This symbol refers to a hazard or  
unsafe practice which can result  
in personal injury or product or  
property damage.  
…In an Area with High Winds  
Securely anchor the outdoor unit down with bolts and a  
metal frame. Provide a suitable air baffle.  
If Necessary, Get Help  
…In a Snowy Area (for Heat Pump-type Systems)  
Install the outdoor unit on a raised platform that is higher  
than drifting snow. Provide snow vents.  
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.  
When Connecting Refrigerant Tubing  
• Keep all tubing runs as short as possible.  
• Use the flare method for connecting tubing.  
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.  
• 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.  
SPECIAL PRECAUTIONS  
When Wiring  
• Check carefully for leaks before starting the test run.  
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 “narrow” or “wide” rather than as “liquid” or “gas.”  
ELECTRICAL SHOCK CAN CAUSE SEVERE PER-  
SONAL 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 tub-  
ing are completed or reconnected and checked.  
When Servicing  
• Turn the power OFF at the main power box (mains)  
before opening the unit to check or repair electrical parts  
and wiring.  
• Highly dangerous electrical voltages are used in this sys-  
tem. Carefully refer to the wiring diagram and these  
instructions when wiring. Improper connections and inad-  
equate grounding can cause accidental injury or death.  
• Keep your fingers and clothing away from any moving  
parts.  
• Ground the unit following local electrical codes.  
• 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.  
• Connect all wiring tightly. Loose wiring may cause over-  
heating at connection points and a possible fire hazard.
