Before Operating The Unit; Installing Procedures And Preparation Before Operation - Yamato Pure Line WL320A Instruction Manual

1. Be sure to connect the earth wire.
・ Connect the power cord with an earth terminal included to an earthed outlet.
・ If a 3-pole power plug with an earth terminal is unavailable, be sure to connect the
earth wire (the green core wire of the power cord) to the ground wire or the ground
terminal to prevent an electrical shock accident from earth leakage.
・ Never connect the earth wire to the gas pipe or water pipe, in order to prevent fire.
・ The earth wire must never be used for grounding of the telephone line and lightning
arrestor. This is to prevent fire and electric shock.
・ Never use the branch socket outlet because it causes hazardous heat generation.
