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 correct diameter 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.
