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 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.

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.

WARNING

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.
