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 tins on the air conditioner
can cut your finger.
When installing...
... in awall: Make sure the wall is strong enough to holdthe 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 roomto prevent "sweating" that can cause dripping
and water damage to wall and floors.
... in moist or uneven Iocatinons: 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 fl-omany moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been
k. left inside the unit being serviced. _'
