•When performing electrical and earthing works, be sure to comply with the 'technical standards of electrical installations' and the 'wiring regulations' in the local regulations.

•Tighten the terminal block screw to 1.2-1.8 N•m (1.2-1.8 kgf•cm).

NOTE

•Each wire is labelled with the corresponding terminal number.

•Use shield cable (Category 5; less than 50pF/m) for noisy environmental site.

•Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. Code designation IEC: 60227 IEC53/CENELEC: H05VV-F, IEC: 60245 IEC66/CENELEC:H07RN-F, IEC: 60245 IEC 57/CENELEC: H05RN-F)

•Power & Communication cable shall not exceed 30m.

CAUTION

•For the terminal block wiring, use a wire with a ring terminal socket only. Regular wires without a ring terminal socket may become a hazard due to overheating of the electrical contact during installation.

•If you need to extend the pipe, be sure to extend the cable, too. The maximum length of each of the cable and pipe used should not exceed 15 metres (✴✴12/18✴✴) and 20 metres (✴✴24✴✴).

•Do not connect two or more different cables to extend the length. This connection may cause fire.

•Each circular terminal must match the size of its corresponding screw in the terminal block.

•After connecting the cables, make sure that terminal numbers on the indoor and outdoor units match.

•Ensure that power and communication cables are separated, they must not be in the same cable.

WARNING

•Connect the wires firmly so that wires cannot be pulled out easily. (If they are loose, it could cause burn-out of the wires.)
