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.
• 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 support or hold the unit, and select a location
for easy maintenance.
…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.
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.
…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.
…At least 2.5 m
Indoor unit of this air conditioner shall be installed in a
height of at least 2.5 m.
…In laundry rooms
Do not install in laundry rooms. Indoor unit is not drip proof.
When Connecting Refrigerant Tubing
WARNING
• 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 high
tension inside the refrigerant cycle.
• Refrigerant gas leakage may cause
fire.
• Do not add or replace refrigerant
other than specified type. It may
cause product damage, burst and
injury, etc.
• 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.
