4. HOW TO INSTALL THE OUTDOOR UNIT
4-1. 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.)
●
Refer to the Fig. 4-1 for the anchor bolt dimensions.
●
Be sure to anchor the feet with the anchor bolts
(M10). In addition, use anchoring washers on the top
side. (Use large square 32 ( 32 SUS washers with
JIS nominal diameters of 10.) (Field supply)
4-2. Drainage Work
Follow the procedure below to ensure adequate drain-
ing for the outdoor unit.
●
For the drain port dimensions, refer to the figure at
right.
●
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
(optional part STK-DS25T) onto the drain port. Seal
the other drain port with the rubber cap supplied with
the drain socket.
●
For details, refer to the instruction manual of the
drain socket (optional part STK-DS25T).
4-3. Routing the Tubing and Wiring
●
The tubing and wiring can be extended out in 4 direc-
tions: 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 3 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.
(2) If the routing direction is down, use a nipper or simi-
lar tool to cut out the lower flange from cover A.

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.
