NOTE: Connecting cable · Wire type : More than 1. 5 mm2 (H07RN-F or 245 IEC66) or 1. 3 mm2 (AWG-16) 8-5-4. Remove the electric parts cover from the outdoor unit. Connect the connecting cable to the terminal as identified with their respective matched numbers on the terminal block of indoor and outdoor unit. When connecting the connecting cable to the outdoor unit terminal, make a loop as shown in the installation diagram of indoor and outdoor unit, to prevent water coming in the outdoor unit. Insulate the unused cords (conductors) from any water coming in the outdoor unit. Proceed them so that they do not touch any electrical or metal parts. ­ 46 ­ FILE NO.
