AFETY CONSIDERATIONS
The precautions listed here are divided into the following two types.
Both cover very important topics, so be sure to follow them carefully.
Warning
■
The equipment is not intended for use in a potentially explosive
atmosphere.
■
Ask your dealer or qualified personnel to carry out installation
work. Do not install the machine by yourself.
Improper installation may result in water leakage, electric shocks
or fire.
■
Perform installation work in accordance with this installation
manual.
Improper installation may lead to water leakage, electric shocks
or fire.
■
When a unit is installed in a small room, it is necessary to take
measures so that the leaked refrigerant amount does not
exceed the limit even if it leaks. As for the measures to prevent
the leak from not exceeding the limit, please consult with your
distributor.
If the leaked amount exceeds the limit, it may cause an oxygen
deficiency accident.
■
Be sure to use only the specified accessories and parts for
installation work.
Failure to use the specified parts may result in water leakage,
electric shocks, fire, or the unit falling.
■
Install the air conditioner on a foundation that can withstand its
weight.
Insufficient strength may result in the fall of equipment and
causing injury.
■
Carry out the specified installation work in consideration of
strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due to falling
of equipment.
■
Make certain that all electrical work is carried out by qualified
personnel according to the local laws and regulations and this
installation manual, using a separate circuit.
Insufficient capacity of the power supply circuit or improper
electrical construction may lead to electric shocks or fire.
■
Make sure that all wiring is secure, using the specified wires and
ensuring that external forces do not act on the terminal
connections or wires.
Incomplete connection or fixing may cause a fire.
■
When wiring between the indoor and outdoor units, and wiring
the power supply, form the wires so that the frontside panel can
be securely fastened.
If the frontside panel is not in place, overheat of the terminals,
electric shocks or a fire may be caused.
■
If refrigerant gas leaks during installation work, ventilate the
area immediately.
Toxic gas may be produced if refrigerant gas comes into contact
with fire.
■
After completing the installation work, check to make sure that
there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the room
and comes into contact with a source of fire, such as a fan
heater, stove or cooker.
■
Before touching electric terminal parts, turn off the power switch.
■
Live parts can be easily touched by accident.
Do never leave the unit unattended during installation or
servicing when the service panel is removed.
■
When planning to relocate former installed units, you must first
recover the refrigerant after the pumping-down operation. Refer
to chapter
"Precaution for pumping-down operation" on page 8 .
■
Do never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
