1. SAFETY PRECAUTIONS
This installation manual describes how to install the outdoor unit only. To install the
indoor unit, refer to the installation manual included with the indoor unit.
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 effi 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.
• Hazard alerting symbols
Electrical
Safety / alert
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
certifi ed dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or mainte-
nance service, including failure to follow the instructions in this document.
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 inwad-
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 drip-
ping and water damage to walls and fl oors.
...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 baffl e.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised support that is higher than drifting snow. Provide
snow vents.
