CAUTION • Gases and vapours other than the target refrigerant gas, may cause semi-conductor sensors to react. Sensors exposed to silicon fumes may be permanently damaged. The accumulation of volatile organic compounds resulting from human occupation in a poorly ventilated room may cause inaccurate operation.

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.
