The specifications of the power cable listed in the table above are applied to theconduit-guarded multi-wire copper cable (for example, YJV copper cable, consisting of PE insulatedwires and a PVC cable jacket) used at and resistible to , and shall be at least those ofordinary polychloroprene sheathed cords. If the working condition changes, they should bemodified according to the related national standard. The specifications of the air switch listed in the table above are applied to the breaker with theworking temperature at . . If the working condition changes, they should be modifiedaccording to the related national standard. The length of the recommended power cable should be less than 49.2 ft (15 m); otherwise, thediameter of the power cable is not enough. The mentioned power cable and transmission line length is just a reference value. It may bedifferent depending on the condition of the installation, humidity or materials. An all-pole disconnection switch , with a contact separation of at least 0.12 in (3 mm) in all poles, shouldbe connected in fixed wiring.-------------------------------------------------------------------------------------------------------------------------7.3 Ground Requirements The air conditioner is classified as a Class I appliance, so the grounding methods must be reliable. The ground wire must be secured on the screw hole with the sign as the right figure. The yellow-green wire of the air conditioner is the ground wire and must be securedwith a tapping screw.

The electric installation should be carried out by the professional as instructed by the local laws,regulations and also this manual. The air switch coupled with the leakage current protection switch must be equipped in thecircuits, which is of enough capacity and of both magnetic and thermal tripping functions incase of a short circuit and overload. The electrical work should use a cable long enough to cover the entire distance with noconnection. If it is unavoidable, ensure the connection is reliable, the externalforces will not impact the wires and the joint is not bare, otherwise it will cause electricalshock or fire . A power cable with the rated voltage and exclusive circuit for the air conditioning should beused. Do not pull the power cable forcefully after it is installed. The diameter of the power cable should be large enough and once it is damaged, it must bereplaced by the dedicated one. The multi-wire copper cable should be used for the power cable and the transmission line.104°F 40°C) 194°F (90°C)104°F (40°C)20
