To minimize the risk of electric shock, you must always plug into a grounded outlet. Do not cut or remove the grounding prong from the power plug. Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated, and the wall receptacle is grounded through the house wiring. If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and circuit checked by a qualified electrician. Temporary Use of an Adapter We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections, use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the adapter is aligned with the large slot in the receptacle for a proper polarity connection. To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage. Warning Never use the appliance with a broken adapter. Temporary Use of an Extended Cord We strongly discourage the use of an extension cord due to potential safety hazards. Warning This appliance should be installed in accordance with national wiring regulations. This manual acts as a guide to explaining product features.

D INSTALLATION 19 Outdoor Unit Terminal block Over 5mm Connecting cable Connecting cable control Cover Control Use a recognized circuit breaker 20A (18K), 25A (24K, 26K) between the power source and the unit. A disconnecting device to adequately disconnect all supply lines must be fitted. CAUTION After the confirmation of the above conditions, prepare the wiring as follows: 1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method of wiring, be guided by the circuit diagram posted on the inside of control cover. 2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.) 3) Specification of power source. 4) Confirm that electrical capability is sufficient. 5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 6) Confirm that the cable thickness is as specified in the power source specification. (Particularly note the relation between cable length and thickness. (Refer to page 11)) 7) Always install an earth leakage circuit breaker in a wet or moist area. 8) The following would be caused by voltage drop. Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the normal function of the overload. 9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 3mm in each active(phase) conductors. 18 INSTALLATION Connecting the Cables between Indoor Unit and Outdoor Unit 1 Connect the cable from Indoor to outdoor unit.
