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
If the warning is not obeyed, it may cause
serious injuries.
CAUTION
If the caution is not observed, it may cause
injury or damage to the equipment.
WARNING
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.
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.
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 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
pumping-down operation" on page
CAUTION
Install drain piping according to this installation
manual to ensure good drainage, and insulate the
pipe to prevent condensation.
Improper drain piping may cause water leakage, and
make the furnitures get wet.
Install the indoor and outdoor units, power wire and
connecting wire at least 1 meter away from televisions
or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
Do not rinse the outdoor unit. This may cause electric
shocks or fire.
