1. When the position of the drain piping has been selected, cut out the corresponding knock-
out from the unit housing.
2. Select the position of the piping hole to be drilled according to the direction of the drain pipe
position selected for the application. The position of the piping hole should be slightly lower
than the wall mounted frame.
3. Drill a hole with the diameter of 2 3/16 inch or 2 3/4 inch (24K unit) for the selected outlet
pipe position. In order to drain smoothly, slant the piping hole on the wall slightly downward
to the outdoor side with a gradient of 5-10°. (As shown below)
4. Insert a sleeve into the hole to prevent the connection piping and wiring from being
damaged when passing through the hole.
