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 screws 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 capacity 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. 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 protector. 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 1/8 inch in each active (phase) conductors. Air purging Air and moisture in the refrigeration system have undesirable effects as indicated below: 1. Pressure in the system rises. 2. Operating current rises. 3. Cooling or heating(only for models with heating function) efficiency drops. 4. Moisture in the refrigerant circuit may freeze and block capillary tubing. 5. Water may lead to corrosion of parts in the refrigeration system. Therefore, the indoor unit and tubing between the indoor and outdoor unit must apply leakage test and be evacuated to remove any noncondensables and moisture from the system. 21 Electrical work and air purging
