WARNING
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 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.
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 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.
