User notice AMS-SVX03A-EN During operation, the total capacity of the indoor units operating at the same time shall not exceed the outdoor unit capacity. Otherwise, it will lead to inadequate indoor unit cooling (heating) capacity. According to the capacity, install an air switch or fuse at each indoor unit and a main air switch for all indoor and outdoor units. The air switch of each indoor unit is used for short circuit protection and abnormal overloading of the indoor unit, which is normally closed. The main switch controls the power supply for all indoor and outdoor units. User must cut off the main power supply for all units before cleaning. User should keep the unit powered on. If user do not use the unit for a long term, please cut off power supply and switch on the main power switch for 24 hours before operation. When the indoor unit receives shutdown signal, the fan would keep running for 20-70s to use residual cool or heat from the heat exchanger and ready for the next operation. If operating modes of the indoor unit and outdoor unit are not in accordance, the indoor unit fault indicator flashes after 5s and the indoor unit stops. In that case, just mode conversion can eliminate the conflict. Cooling mode is in accordance with dry or fan mode, while non modes are in accordance with heating mode. 3
