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.

This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.

This symbol refers to a hazard or unsafe practice which can result in personal injury or product or property damage.

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.

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.

SPECIAL PRECAUTIONS

• During installation, connect before the refrigerant system and then the wiring one; proceed in the reverse orden when removing the units.

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.

• 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.

When installing...

• 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.

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 test

ing 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.

WARNING

CAUTION

WARNING

… 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

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

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 a snowy area (for heat pump-type systems)

Install the outdoor unit on a raised platform that is higher then drifting snow. Provide snow vents.

EXCT: 2P plug (red): Can be used for demand control. When imput is present, forces the unit to operate

(CN073) with the termostat OFF.

DISP: 2P plug (white): Short-circuiting this plug allows the unit to be operated by the remote controller, even if it is not (CN072) 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: 2P plug (white): Test pin. Short-circuiting this pin allows the indoor FM (H fan speed), drain pump, (CN071) 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.
