PRECAUTIONS FOR SAFETY
WARNING
Warning on installation
Be sure to leave the installation work to the dealer or a store
specializing.
The exclusive knowledge and technology are required for installation work.
Do not perform installation by yourself. If an incomplete installation is performed,
a fire, electric shock, injury, or water leakage may be caused.
Be sure to use the products sold separately which are specified by us.
For the products sold separately, be sure to use those specified by us. Otherwise,
a fire, electric shock, or water leakage may be caused. For installation work,
leave it to special engineer.
When installing the units in a small room, take measures so that the
refrigerant will not exceed the critical concentration if it leaks.
CAUTION
Related to countermeasures against the critical concentration, perform the installation work upon consul-
tation with the dealer. If the refrigerant leaks and exceeds the critical concentration, oxygen deficiency
may be caused.
Check whether earthing work is performed correctly.
A grounding is necessary. If the earthing work is incompletely, an electric shock may be caused.
(For details, conform to the local regulation in each area.)
Warning on use
Do not expose your body directly in cool air for a long time, or do not
cool you excessively.
It causes the worse of physical condition or trouble on health.
Never insert a finger or bar into the air inlet port or air outlet port of
air.
Since the fan rotates in high speed inside of the unit, an injury may be caused.
When a trouble (burnt smell, etc.) is felt, stop the operation, turn off
the power switch, and contact the dealer who you have
purchased the air conditioner.
If keeping operation as the air conditioner is defective, a fire, electric shock, or
trouble may be caused.
