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 .
• 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.
• To prevent possible hazards from insulation failure,
the unit must be grounded.
• This equipment is strongly recommended to be installed
with Earth Leakage Circuit Breaker (ELCB) or Residual
Current Device (RCD). Otherwise, it may cause electrical
shock and fire in case of equipment breakdown or
insulation breakdown.
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 fl oors.
CAUTION
Keep the fire alarm and the air
outlet at least 5 feet (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 baffl e.
…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
• Ventilate the room immediately, in the event that is
• Pay particular attention to refrigerant leakages.
refrigerant gas leaks during the installation. Be careful not
to allow contact of the refrigerant gas with a fl ame as this
will cause the generation of toxic gas.
• Keep all tubing runs as short as possible.
• Apply refrigerant lubricant to the matching surfaces of
the fl are 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.
WARNING
•
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.
•
it produces a toxic gas.
•
When performing piping work, do not mix air
If the refrigerant comes in contact with a flame,
Do not add or replace refrigerant other than
specified type. It may cause product damage,
burst and injury etc.
