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 by
3 mm 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.

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other
adverse environmental effects.
The check shall also take into account the effects of aging or continual vibration from sources such as
compressors or fans.

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

It may need two or more people to carry out the installation work.

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 Storing...
WARNING

The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as
specified for operation.

The appliance shall be stored in a room without continuously operating open flames (for example: an
operating gas appliance) and ignition sources (for example: an operating electric heater).

The appliance shall be stored so as to prevent mechanical damage from occurring.
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 cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction.

An unventilated area where the appliance using flammable refrigerants is installed shall be so constructed that
should any refrigerant leak, it will not stagnate so as to create a fire or explosion hazard.

Ducts connected to an appliance shall not contain a potential ignition source;

For appliances connected via an air duct system to one or more rooms, the supply and return air shall be directly
ducted to the space.
...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 at least 1.5 m away from the unit.
CAUTION
...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 1.8 m (horizontal installation)
Installation height for indoor unit shall be at least 1.8 m.
