3. OUTDOOR UNIT INSTALLATION
• When the outdoor unit will be exposed to strong
wind, fasten it with bolts at the places indicated by
the arrows. (Fig. 22)
• Since the drain water flows out of the outdoor unit
during heating operation, install the drain pipe sold
separately and connect it to an commercial 16 mm
hose. (Heat & Cool model only)
• When installing the drain pipe, plug all the holes (•
holes at two places) other than the drain pipe
mounting hole in the bottom of the outdoor unit
with putty so there is no water leakage. (Fig. 22)
