Safety caution
Explanation of indications
Indicates possibilities that a death or serious injury of personnel is caused by an incorrect handling.
Indicates contents that an injury (*
*1: "Injury" means a hurt, a burn, or an electric shock which does not require hospitalization or a long-term going to the hospital.
*2: "Property damage means an enlarged damage concerned to property, or breakage of materials.
• After installation work has finished, check there is no trouble by a test operation, and explain using method and
maintenance method to the customers based on the Owner's Manual.
Please ask the customers to keep this Installation Manual together with the Owner's Manual.
Ask a shop or a professional dealer to install the air conditioner.
If you will install by yourself, a fire, an electric shock, or water leak is caused.
Take measures so that the refrigerant does not exceed the limit concentration even if it leaks when installing the air conditioner
in a small room.
For the measures not to exceed the limit of concentration, contact the dealer. If the refrigerant leaks and it exceeds the limit of
concentration, an accident of oxygen shortage is caused.
Install the air conditioner at a place which is satisfactorily bearable to weight.
If strength is insufficient, the unit may fall down resulting in human injury.
Perform a specified installation work against a strong wind such as typhoon or earthquake.
If the air conditioner is imperfectly installed, an accident by falling or dropping may be caused.
If refrigerant gas leaks during installation work, ventilate the room.
If the leaked refrigerant gas approaches to fire, noxious gas may generate.
After installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks in the room, and approaches to fire such as fan heater, stove or kitchen range, generation of noxious gas may be
caused.
Never recover refrigerant in the outdoor unit.
Be sure to use a refrigerant recovery device to recover refrigerant in reinstallation or repair work.
Recovery of refrigerant in the outdoor unit is unavailable; otherwise a serious accident such as crack or human injury is caused.
A person qualified for the electric work should deal with the electric construction conforming to the regulations of the local
electric company and the Installation Manual. Be sure to use the exclusive circuit.
If there is capacity shortage of the power supply circuit or incomplete installation, a fire or an electric shock is caused.
For cabling, use the specified cables and connect them securely so that external force of cable does not transmit to the
terminal connecting section.
If connection or fixing is incomplete, a fire, etc. may be caused.
Be sure to connect earth wire.
Do not connect earth wire to gas pipe, water pipe, lightning rod, nor earth wire of telephone.
If grounding is incomplete, an electric shock is caused.
Do not install the air conditioner at a place where combustible gas may leak.
If gas leaks and is collected at surrounding the unit, the production of fire may be caused.
Be sure to attach an earth leakage breaker; otherwise an electric shock may be caused.
Using a torque wrench, tighten the flare nut in the specified method.
If the flare nut is exceedingly tightened, the flare nut is broken and a refrigerant leakage may be caused after a long time has passed.
