Installation of the Drain Hose
● Installation of Drain Piping
CAUTION!
Install the drain hose in accordance with the instructions in this installation manual and keep
the area warm enough to prevent condensation. Problems with the piping may lead to water
leaks.
1. Keep piping as short as possible and slope it downwards at a gradient of at least 1/100 so
that air may not remain trapped inside the pipe.
2. Keep pipe size equal to or greater than that of the connecting pipe.
3. Install the drain piping as shown and take measures against condensation. Improperly
rigged piping could lead to leaks and eventually wet furniture and belongings.
