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 sys-
tem. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inade-
quate grounding can cause accidental injury or death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
When Transporting
Be careful when picking up and moving the indoor and out-
door units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin alu-
minum 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 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-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 “narrow” or “wide” rather than as “liquid” or “gas.”
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.
