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. WARNING This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death. CAUTION 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. WARNING When wiring ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY A QUALIFIED, EXPERIENCED ELECTRICIANS SHOULD ATTEMPT TO WIRE THIS SYSTEM. 0.8180.531.00 Do not supply 05/2007 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...... In a ceiling or wall Make sure the ceiling/wall 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 than drifting snow. Provide snow vents. When connecting refrigerant tubing 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 testng 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. 2

7. FUNCTION 7-1 Diagnostic With this feature is possible to have a visual signal that a trouble is occurring. This mode is always active and the signalling is made through the display board LEDS. In case of no troubles the LEDS status follows its normal function. The detected troubles are showed to the user/technician using the 3 (5) leds of the indoor unit receiver and the 5 leds on the outdoor pcb. For each fault there are different effects upon the operation of the A/C: NOTES The troubles are showed according to a priority list that is in case of more than one trouble present, is always showed, at first, the one with the highest priority (3 2 1 etc). Sensor damaged means a situation where sensor is short-circuited or opened. In case of damaged sensors, the system (CM, FMO, FMI etc), if in OFF state, does not start. system does not operate. To restart the system, power re-setting (off-on) is required note: before restoring power, adjust the dip-switch status on idu according to the connection pipes system does not operate. as soon as fault is cleared, the system automatically restart after 3 min during this time, the signalling is showed EFFECTS 16
