SPECIAL PRECAUTIONS

When Wiring
WARNING
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.
• Provide a power outlet to be used exclusively for each
unit, and a power supply disconnect, circuit breaker and
earth leakage breaker for overcurrent protection should
be provided in the exclusive line.
• Provide a power outlet exclusively for each unit, and
full disconnection means having a contact separation
in all poles must be incorporated in the fixed wiring in
accordance with the wiring rules.
• To prevent possible hazards from insulation failure,
the unit must be grounded.
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 Room
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to
walls and floors.
Keep the fire alarm and the air outlet
CAUTION
at least 1.5 m away from the unit.
...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
• When performing piping work do
not mix air except for specifIed
refrigerant (R410A) in refrigeration
cycle. It causes capacity down, and
risk of explosion and injury due to
WARNING
high tension inside the refrigerant
cycle.
• Refrigerant gas leakage may cause
fire.
• Ventilate the room well, in the event that is refrigerant
gas leaks during the installation. Be careful not to allow
contact of the refrigerant gas with a flame as this will
cause the generation of poisonous gas.
• 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.
• Do not leak refrigerant while piping work for an
installation or re-installation, and while repairing
refrigeration parts.
Handle liquid refrigerant carefully as it may cause
frostbite.
