IMPORTANT!
Please read before installation
This air conditioning system meets strict safety and operating
standards.
For the installer or service person, it is important to install or
service the system so that it operates safely and efficiently.
For safe installation and trouble-free operation, you must:
• Carefully read this instruction booklet before beginning.
• Follow each installation or repair step exactly as shown.
• Observe all local, state and national electrical codes.
• Pay close attention to all warning and caution notices given in
this manual.
•The unit must be supplied with a dedicated electrical line.
• Ground the unit following local electrical codes.
• The Yellow/Green wire cannot be used for any connection
different from the ground connection.
• Connect all wiring tightly. Loose wiring may cause overheating
at connection points and a possible fire hazard.
• Do not allow wiring to touch the refrigerant tubing, compressor,
or any moving parts of the fan.
• Do not use multi-core cable when wiring the power supply and
control lines. Use separate cables for each type of line.
When transporting
Be careful when picking up and moving the indoor and outdoor
units. Get a partner to help, and bend your knees when lifting to
reduce strain on your back. Sharp edges or thin aluminium fins on
the air conditioner can cut your fingers.
WARNING
This symbol refers to a hazard or unsafe practice which can result
in severe personal injury or death.
When installing...
… In a ceiling
Make sure the ceiling is strong enough to hold the unit-weight.
It may be necessary to build a strong wooden or metal frame to
provide added support.
… In a room
CAUTION
This symbol refers to a hazard or unsafe practice which can result
in personal injury or product or property damage.
Properly insulate any tubing run inside a room to prevent
"sweating", which can cause dripping and water damage to
walls and floors.
... In moist or uneven locations
If necessary, get help
These instructions are all you need for most installation sites and
maintenance conditions.
If you require help for a special problem, contact our sale/service
outlet or your certified dealer for additional instructions.
Use a raised concrete base to provide a solid level foundation
for the outdoor unit. This prevents damage and abnormal
vibrations.
... In area with strong winds
Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.
In case of improper installation
The manufacturer shall in no way be responsible for improper
installation or maintenance service, including failure to follow the
instructions in this document.
... In a snowy area (for heat pump-type systems)
SPECIAL PRECAUTIONS
When connecting refrigerant tubing
• During installation, connect before the refrigerant system and
then the wiring one; proceed in the reverse orden when removing
the units.
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare
and union tubes before connecting them; screw by hand and
then tighten the nut with a torque wrench for a leak-free
connection.
• Check carefully for leaks before starting the test run.
WARNING
When wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY QUALIFIED,
EXPERIENCED ELECTRICIANS SHOULD ATTEMPT
TO WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tubing are
completed or reconnected and checked, to ensure the grounding.
• Highly dangerous electrical voltages are used in this system.
Carefully refer to the wiring diagram and these instructions when
wiring.
Improper connections and inadequate grounding can cause
accidental injury and death.
2
Install the outdoor unit on a raised platform that is higher then
drifting snow. Provide snow vents.
NOTE:
Depending on the system type, liquid and gas lines may be either
narrow or wide. Therefore, to avoid confusion, the refrigerant
tubing for your particular model is specified as narrow tube for
liquid, wide tube for gas.
When servicing
• Turn the power OFF at the main power board before opening
the unit to check or repair electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after the work, remembering to check that no
metal scraps or bits of wiring have been left inside the unit being
serviced.
• Ventilate the room during the installation or testing the refrigeration
system; make sure that, after the installation, no gas leaks are
present, because this could produce toxic gas and dangerous
if in contact with flames or heat-sources.

2P plug (red): Can be used for demand control. When imput is present, forces the unit to operate
with the termostat OFF.
DISP:
(CN072)
2P plug (white): Short-circuiting this plug allows the unit to be operated by the remote controller, even if it is not
connected to an outdoor unit. (In this case, alarm "E04", which indicates trouble in the serial communication
between the indoor and outdoor unit, does not occur.)
CHK:
(CN071)
2P plug (white): Test pin. Short-circuiting this pin allows the indoor FM (H fan speed), drain pump,
flap motor (F1 position), and electronic expansion valve full-open position to checked. However this function
turns OFF if the indoor unit protection mechanism is activated. The unit can be operated even if the remote
controller and outdoor unit are not connected. However even if the remote controller cannot is connected,
it cannot be used to operate the unit. This function can be used for short-term tests.

About EEPROM
(Erasable Programmable Read-Only Memory)
EEPROM is a component in which the various information necessary for functionning
can be electronically written or erased. This component holds informations
that is essential for the running of the unit, and must be handled with care.
