[. . . ] Installation Location · A place which provides enough space around the outdoor unit as shown in the diagram. · A place which can bear the weight of the outdoor unit and does not allow an increase in noise level and vibration. · A place where the operation noise and discharged air do not disturb neighbors. · A place which is not exposed to a strong wind. · A place free of combustible gases. · A place which does not block a passageway. · When the outdoor unit is to be installed in an elevated position, be sure to secure its feet. · Piping connections to the outdoor unit should be arranged in the sequence A, then B, starting from the bottom. (For each piping connection, the gas pipe is on the bottom and the liquid pipe on top. ) · When multiple indoor units are to be connected to the outdoor unit, make sure the ends of the pipes and wires from each indoor unit are connected to the outdoor unit correctly. (Problems caused by indoor units being connected to the outdoor unit incorrectly are very common in multiple-unit installations. ) · The length and height differences of the connecting pipes, between the indoor and outdoor units, must be within the ranges indicated below. · Total piping length: Two room (A + B) Multi · This air conditioner accepts a connection piping length of up to 30 m. · There is no need to add refrigerant as long as the length of the connection piping is 20 m or less. · · · · · · You will need to add 20 g of refrigerant per meter of added connection piping for installations requiring connection piping to be between 21 m to 30 m. · Minimum piping length: A or B = 2 m or more · Maximum indoor piping length: A or B = 20 m or less · Maximum piping height difference: A or B = 10 m or less · Maximum piping / height difference between two rooms = 10 m or less If the outdoor unit is to be mounted on a wall, make sure the platform supporting it is sturdy enough. The platform should be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration should be given to ensuring that the outdoor unit will not fall. When the outdoor unit is to be mounted high on a wall, take particular care to ensure that parts do not fall, and that the installer is protected. When doing installation work at ground level, it is usual to make wiring and pipe connections to the indoor units, first, and then to make connections to the outdoor unit. However, if outdoor work is difficult it is possible, instead, to make changes to the procedure. For example, by making adjustments to the wiring and piping lengths on the inside (rather than the outside). A place where the drain water does not cause any problems. The outdoor unit should not be installed with one indoor unit only. Be sure the (outdoor) unit is installed with at least two indoor units.
