SPECIAL PRECAUTIONS
WARNING
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.
• 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.
• ELCB must be incorporated in the fixed wiring.
Circuit breaker must be incorporated in the fixed wiring
in accordance with the wiring regulations.

•
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…
Select an installation location which is rigid and strong
enough to sup port or hold the unit, and select a location
for easy maintenance.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweatin
g” that can cause dripping and water damage to
walls and floors.
CAUTION
Keep the fire alarm and the air outlet
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.
