4. 4. Drain installation
CAUTION
• Perform drain work in accordance with this Manual, and ensure that the drain water
is properly drained. If the drain work is not carried out correctly, water may drip down
from the unit, wetting the furniture.
• When the outdoor temperature is 32 °F (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 extremely cold weather. (Reverse cycle model only).
• As the drain water fl ows out of the outdoor unit during heating operation, install the
drain pipe and connect it to a commercial 5/8 in. (16 mm) hose. (Reverse cycle
model only)
• When installing the drain pipe, plug all the holes other than the drain pipe mounting
hole in the bottom of the outdoor unit with putty so there is no water leakage. (Reverse
cycle model only)
