its electrical wiring. Do not attempt to do it by yourself (charges are additional). If improperly performed by yourself, it may cause leakage, electric shock or fire. · Do not use a metal wire or copper wire as a fuse to prevent from failure or fire. · When installing, do not use an extended power cord or a power cord with excess

bending

N (radius less than 20mm). Also, use the cable tie supplied with the base-pan to secure it. Do not place the

G cord inside the unit body or it may cause short circuit or abnormal heat leading to a fire due to insulation

damage by an overly compressed cord.

· Use only on single outlet circuit exclusive for the air conditioner.
· Ensure the mounting support is firm and steady or there is a risk the unit may fall. · To avoid electric shock in case of current leakage, be sure to connect the air conditioner to the
ground. The ground wire diameter should be 2.5 mm² to 6 mm². Also, the end of the ground wire must be crimped with a round terminal before securing it and must not be loose by accident. Do not connect the ground wire to the gas pipe, water pipe, lightning rod, and the telephone line. If the ground wire is not installed properly, there is a risk of electric shock. If the unit is not grounded, the protective circuit such as lightning striking protection will not work properly.

· To avoid carelessness from power companies or other accidents that cause over current to get into the unit via the ground wire resulting in damage to the unit, be sure to install an earth leakage circuit breaker. Consult the
dealers (a registered water and electrical engineering dealer) for details. If no earth leakage circuit breaker is
installed, there is a risk of accident such as electric shock to occur.
