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

For year round cooling applications with low indoor
humidity conditions, such as Electronic Data
Processing rooms, contact your dealer or see the
engineering databook or the service manual.

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.

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.

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 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 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 power
switch.
