NOTES:
• If the space is larger than stated above, the condition will be the same as when there is no
obstacle.
• When installing the outdoor unit, be sure to open the front and left side to obtain better opera-
tion efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the
drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe and drain
cap. If the drain pipe and drain cap are used, the drain water in the pipe may freeze in ex-
tremely cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it
might become difficult to get warm, and it is likely to cause product malfunction. Construct a
canopy and a pedestal, or place the unit on a high stand that is locally installed.
