[. . . ] Snow protection plate Front Snow protection hood ■ Precautions for Installation • When the outdoor unit is to be installed in an elevated position, be sure to secure its feet. • If the outdoor unit is to be mounted on a wall, make sure the base plate supporting it is sturdy enough. • The base plate should be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration should be given to ensure that the outdoor unit will not fall. • When the outdoor unit is installed in a place that is always exposed to strong wind such as a coastal area or on a high story of a building, secure the normal fan operation using a duct or a wind shield. • Especially in windy areas, install the unit in such a way as to prevent the admission of wind. • 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 units. However, if outdoor work is difficult, you can change the procedure. For example, by making adjustments to the wiring and piping lengths on the inside (rather than the outside). • When using an air conditioner under low outside temperature conditions (Outside temp: -5 °C or lower) In COOL mode, prepare a duct or wind shield so that it is not affected by the wind. At least 500 mm Anchor bolts Snow accumulation line Holding frame Fixing the Outdoor Unit Fix the outdoor unit using attachment bolts. • Use 8 mm or 10 mm anchor bolts and nuts. • Do not allow the attachment bolts to protrude by more than 15 mm. • Install the outdoor unit at ground level. • Attach the vibration-proof rubber pads under the fixing legs.
