Toshiba rav-sm1103at-e Installation Manual page 9

• 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.
• When installing the unit in an area where
snowfalls may be heavy, take steps to prevent the
unit from being adversely affected by the fallen or
accumulated snow.
• Either make the foundation higher or install a
stand (which is high enough to ensure that the
unit will be above the fallen or accumulated
snow) and place the unit on it.
• Attach a snow shield (locally procured).
