Page 4: Safety Precautions
1. Safety Precautions  Read the following “SAFETY PRECAUTIONS” carefully before installation.  Electrical work must be installed by a licensed electrician. Be sure to use the correct rating and main circuit for the model to be installed.  The caution items stated here must be followed because these important contents are related to safety. The meaning of each indication used is as below.
Page 5 WARNING Install at a strong and firm location which is able to withstand the set’s weight. If the strength is not enough or installation is not properly done, the set will drop and cause injury. This equipment is strongly recommended to be installed with Residual Current Device (RCD) on-site according to the respective national wiring rules or country–specific safety measures in terms of residual current.
Page 6 CAUTION Power supply connection to Indoor Unit.  Power supply point should be in easily accessible place for power disconnection in case of emergency.  Must follow local national wiring standard, regulation and this installation instruction.  Strongly recommended to make permanent connection to a circuit breaker. Power supply 1: Use approved 20A 4-poles circuit breaker with a minimum contact gap of 3.0 mm.
