Safety 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.
For use of air-conditioning units in applications with temperature
alarm settings it is advised to foresee a delay of 10 minutes for
signalling the alarm in case the alarm temperature is exceeded.
The air-conditioning unit may stop for several minutes during
normal operation for "defrosting of the indoor unit" or when in
"thermostat-stop" operation.
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.
Consult your local dealer regarding what to do in case of
refrigerant leakage. When the air conditioner is to be installed in
a small room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen depletion.
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 fall 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 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 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.
Never leave the unit unattended during installation or servicing
when the service panel is removed; live parts can be easily
touched by accident.
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 10
.
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.

Installation manual
READ THESE INSTRUCTIONS CAREFULLY BEFORE
INSTALLATION. KEEP THIS MANUAL IN A HANDY
PLACE FOR FUTURE REFERENCE.
IMPROPER INSTALLATION OR ATTACHMENT OF
EQUIPMENT OR ACCESSORIES COULD RESULT IN
ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY
TO USE ACCESSORIES, OPTIONAL EQUIPMENT, AND
SPARE PARTS MADE BY DAIKIN WHICH ARE
SPECIFICALLY DESIGNED FOR USE WITH THE
EQUIPMENT AND HAVE THEM INSTALLED BY A
PROFESSIONAL.
IF UNSURE OF INSTALLATION PROCEDURES OR USE,
ALWAYS CONTACT YOUR DAIKIN DEALER FOR
ADVICE AND INFORMATION.
WARNING
If the warning is not observed, it may cause serious casualties.
CAUTION
If the caution is not observed, it may cause injury or damage to the
equipment.
