The permitted installation positions with horizontal motor shaft and
electronic module facing up (0°) are shown in Fig. 18. The permissible
installation positions with electronic module mounted on the side
(+/- 90°) are not shown. Any installation position is allowed except for
"electronic module facing down" (- 180°). The venting of the pump is
only ensured when the air vent valve is pointing upwards (Fig. 18, Item 1).
Only in this position (0°) can condensate be directed away via an existing
drilled hole, pump lantern and motor (Fig. 18, Item 2).
The permitted installation positions with horizontal motor shaft are
shown in Fig. 19. All installation positions except for "motor facing
down" are allowed.
The motor impeller unit can be arranged in four different positions,
relative to the pump housing (each shifted by 90°).
NOTE:
To make the installation work easier, it can be helpful to install the
pump in the piping without electrical connection and without filling
of the pump or system (see chapter 10.2.1 "Replacing the mechanical
seal" on page 110 for installation steps).

change when doing this).

NOTE:
Be sure that the O-ring (Fig. 6, Item 1.14) is not installed in a twisted
position or squeezed during installation.
