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 finger.
When installing...
... in a wall: Make sure the 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 wall and floors.
... in moist or uneven locatinons: Use a raised concrete pad or concrete blocks 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 Pump Model): Install the outdoor unit on a raised platform that is
higher than drifting snow. Provide snow vents.
When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• 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.
Special warnings
WARNING
• Installation or repairs made by unqualified persons can result in hazards to you and others.

• Throughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc. In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner.
• Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.
