2.3.8 Installation of Condensate Piping

(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 condensate piping as shown and take measures against condensation. Improperly
rigged piping could lead to leaks and eventually property damage.
