Page 13: Mounting
Mounting Please use a connecting wire (accessory) and an interconnecting cable (procured locally) to connect to indoor unit terminal board cable. If crimping tools are not available, please use other reliable methods for connection. Do not only use the insulating tape to connect; otherwise it can be dangerous. Since the Leak Detector cable has no polarity that is OK if the indoor unit's terminal A and terminal B are inversely connected. - Page 14 In case of mounting to wall box In case of mounting to wall box, cut the plastic stud in the accessory to a suitable length for filling the gap between the rear cover and the wall box. Then use the M4 screws in the accessory to fix the rear cover to the wall box through the plastic stud.
