3. HOW TO INSTALL THE OUTDOOR UNIT
3-1. Installing the Outdoor Unit
Use concrete or a similar material to create 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 as illustrated below the anchor bolt dimensions.
●
Be sure to anchor the feet with anchor bolts (M10 or 3/8"). In
●
addition, use anchoring washers on the top side. (Use SUS
washers with nominal diameter of 10 or 3/8".) (Field supply)

3-2. Drainage Work
Follow the procedure below to ensure adequate draining for the
outdoor unit.
For the drain port dimensions, see the section 3-1.
●
Ensure a base height of 15 cm or more at the feet on both
●
sides of the unit.
When using a drain pipe, install the drain socket (field
●
supply) onto the drain port. Seal the other drain port 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.
3-3. Routing the Tubing and Wiring
Unit: mm
The tubing and wiring can be extended out in 4 directions
●
(front, rear, right, and down):
The service valves are housed inside the unit. To access
●
them, remove the inspection panel. (To remove the
inspection panel, remove the 2 screws, then slide the panel
downward and pull it toward you.)
(1) If the routing direction is through the front, rear, or right,
use a nipper or similar tool to cut out the knockout holes for
the inter-unit control wiring outlet, power wiring outlet, and
tubing outlet from the appropriate covers A and B.
When routing the wiring, be sure to attach each supplied
protection bushing to the edges around the wiring outlet
holes in order to protect the wiring from scratches by the
cutting burr.
(2) If the routing direction is down, use a nipper or similar tool
to cut out the lower flange from cover A.

* Protect the outdoor unit wiring with a conduit material or
supplied protection bushing to avoid damages by the edges of
knockout hole.
* Use sealing putty to seal off the hole to prevent the dust and
insects from entering the wiring outlet holes and the tubing
outlet.
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.
