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
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 con-
nection 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 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 nar-
row 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.

This air conditioner uses new refrigerant HFC (R410A). 5 cm or over The basic installation work procedures are the same as conventional refrigerant (R22) models. However, pay careful attention to the following points: (1) Since the working pressure is 1.6 times higher than that of conventional refrigerant(R22) mod- els, some of the piping and installation and service tools are special.(See the table below.) Especially, when replacing a conventional refrigerant(R22) model with a new refrigerant R410A model, always replace the conventional piping and flare nuts with the R410A piping and flare nuts. -
