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

reconnected and checked.

•

Highly dangerous electrical voltages are used in this system. Carefully re-

fer to the wiring diagram and these instructions when wiring. Improper con-

nections 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 connec-

tion points and a possible fire hazard.

WARNING:

CAUTION:

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 fingers.

When Installing...

...In a Ceiling or Wall

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.

...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.

...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 abnor-

mal 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-type Systems)

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.

•

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.

•

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 “small” or “large” rather than as

“liquid” or “gas”.

When Servicing

•

Turn the power OFF at the main circuit breaker panel 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.

•

After installation, explain correct operation to the customer, using the

operating manual.
