HOW TO INSTALL 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 the figure shown below for the anchor bolt dimensions.
Be sure to anchor the feet with anchor bolts (M8). In addition, use anchoring washers on the top side.
(Use large square 32 × 32 SUS washers with JIS nominal diameter of 8.) (Field supply)

Drainage Work
Follow the procedure below to ensure adequate draining for the outdoor unit.
For the drain port dimensions
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-DS13U) onto the drain port.
Seal the other drain port with the rubber cap supplied with the drain socket.
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.
