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.
Using the tool or piping materials exclusive to R410A, install the air conditioner surely according to this
Installation Manual.
The pressure of the used HFC system R410A refrigerant is higher approx. 1.6 times of that of the former refrigerant.
If the exclusive piping materials are not used, or there is imperfection in installation, a crack or an injury is caused
and also a water leak, an electric shock, or a fire may be 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 the 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 wiring, use the specified wires and connect them securely so that external force of wire 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.
