HOW TO INSTALL THE OUTDOOR UNIT

Installing the Outdoor Unit
● Use concrete or a similar material to make the base, and
ensure good drainage.
● Ordinarily, ensure a base height of 5 cm or more. If a drain
pipe is used, or for use in cold-weather regions, ensure a
height of 15 cm or more at the feet on both sides of the unit.
(In this case, leave clearance below the unit for the drain
pipe, and to prevent freezing of drainage water in cold-
weather regions.)
● See Fig. 1-11-1 for the anchor bolt dimensions.
● Be sure to anchor the feet with anchor bolts (M10). In
addition, use anchoring washers on the top side.
(Use large SUS washers with nominal diameter of 10.) (Field

Drainage Work

The drain water will be discharged from the unit during heating
or defrosting operation mode.
Select an appropriate location with good drainage system.
(In winter, there is a risk of slipping caused by freezing
depending on the installation location.)
● Ensure a height of 15 cm or more at the feet on both sides of
the unit.
● Precautions for Installation in Heavy Snow Areas.
The platform should be higher than the maximum snow depth
+ 50 cm.
(In this case, leave clearance below the unit for the drain
pipe, and to prevent freezing of drainage water in cold-
weather regions.)
● When using a drain pipe, install the drain socket (Field
supply) onto the drain hole. Seal the other drain hole with the
rubber cap (Field supply). For details, refer to the instruction
manual of the drain socket (Field supply).
After completing the installation work of the drain socket,
make sure that the water does not leak from any part of
connection.
● In cold regions (where the outdoor temperature can drop to
below 0° for 2 to 3 consecutive days), the drain water may
freeze and may prevent the fan from operating. For this
case, do not use the drain socket (Field supply).

Routing the Tubing and Wiring
● See Fig. 1-11-1.
CAUTION
● Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit. Increased
noise will result if the tubing contacts these parts.
● When routing the tubing, use a tube bender to bend the tubes.
● In cold-weather regions, in order to prevent drainage
water from freezing, do not install the drain socket cap.
Also take steps to prevent water from accumulating
around the unit.
