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.

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.
