Safety PrecautionsRead this ìsafety precautionsî carefully and thoroughly before implementation to ensure proper installation.These precautions whose marks and contents as the following MUST be complied with for they includeimportant points concerning safety.Contents marked with this sign concern personal safety of the user. Improperoperation can cause personal death or injury.Warning!Notice! Contents marked with this sign concern safety of the product and user. Improperoperation can cause personal injury or damage of machine.Trial run MUST be done after installation of the assembly to ensure no disorders occur. Meanwhile,explain method of use and trouble-shooting to the user according to the operation manual.In addition, this installation instruction and operation manuals should be kept by the user.Warning!Installation MUST be implemented by authorized organization and professional personnel.Unauthorized installation may cause water leakage, electric shock and fire hazard etc.Installation MUST be executed in accordance with this installation manual.Improper installation may cause water leakage, electric shock and fire hazard etc.Ask installation personnel to do preventions against leakage of refrigerant. While installing insmall room, proper preventions should be made to restrict leaking refrigerant within thicknesslimit even leakage occurs. Contact authorized organizations and ask them to do such prevention.Leakage of refrigerant exceeding thickness limit can easily cause hazard of oxygen shortage.Location of installation should be strong enough to bear the weight of machine, which cannot beinstalled on unspecified metal structures (e.g. burglarproof net)Installation support of insufficient strength can cause falling of the machine and personal injuries.Install as required to guard against typhoon, earthquake etc.Installation not as required can cause overturn of the machine resulting accidents.If thereís any leakage of refrigerant during installation, ventilation measures should be madeaccordingly.Contact between refrigerant vapor and fire can produce poisonous gas.Ensure thereís no leakage of refrigerant after finishing installation.If refrigerant vapor leaking indoors and contacts with fire sources such as blowing warmer andstove etc., poisonous gas can be produced.Use special circuit of power supply during installation and make fixed wiring layout accordingto national wiring standard by certified electricians. Insufficient capacity of power supply circuitor improper wiring layout can cause electric shock and fire hazards.Wiring layout MUST apply specified power cables and be grounded reliably. Ensure reliabilityof connections in parts of terminals for improper connection or fixing can cause fire hazard etc.MUST be grounded.Grounding line CANNOT be connected to gas pipe, tapping pipe, lighting rod or earth of telephoneetc.Improper grounding can cause electric shock.1
